as a business owner, I have encountered many challenges. Over

the years, I have learned valuable lessons from the logistical,

operational and financial challenges I have faced. By investing in

the right people and equipment, it has become much easier to overcome

problems and make my business a success. Through my involvement with

CSDA, I have acquired valuable knowledge from my peers. Knowledge that

I now share with others in order to help them with their own challenges.

Challenges are nothing new to CSDA contractors, nor are they things

that we shy away from. We often work on the front line of many high-

profile projects, racing against critical deadlines. Over the last several

years, CSDA contractors have been involved with demolition, renovation

and new-build projects at locations affected by devastating events. This

month, as we mark the 10th anniversary of the September 11th terrorist

attacks, members of CSDA are still working at the Ground Zero site in New

York City, proudly working to rebuild this area. In Louisiana, contractors

continue to help cities get back on their feet following the destruction

caused by Hurricane Katrina. This issue of Concrete Openings features

one such job. More recently, when the weekend-long closure of the I-405

highway took place in California, dubbed “Carmageddon” because of the

potential traffic problems it would cause, a CSDA contractor was on site to

cut the roadway and make sure the general contractor was able to reach

a very critical deadline. CSDA members are often one of the “behind-the-

scene subcontractors” whose critical tasks heighten the general contractor’s

reputation when deadlines are met.

What is it about CSDA members that motivates them to seek out

and ultimately succeed on these projects, and why are they chosen over

other contractor companies? Is it a desire for the adrenalin rush during

the job, or the thrill of accomplishment when a difficult job is completed?

Is it the mind set that they perform complex cutting work that some

general contractors cannot? What sets CSDA members apart from their

competition? For me, it is the confidence they feel from knowing their

operators are the industry’s best-trained and most well-equipped. If I was

running a project that required concrete cutting, I would be sure to have

a skilled CSDA contractor on my speed dial. The association runs several

hands-on training classes throughout the year, with Operator Certification

classes scheduled each November.

There will always be challenges to face in all aspects of life. It is how we

respond to those challenges that define us. CSDA has been helping sawing

and drilling businesses overcome their challenges and remain successful for

almost 40 years, and will continue to do so in the future.

We understand what contractors like George Cramer go through every day. So every day, we push ourselves to perfect our tools and technology to makea rough, dirty job a little easier and you even more effective.

Raising the Roof at BC Place Replacement of Vancouver Stadium Roof Aided by Diamond Tool Cutting

a stadium with the world’s largest air-supported roof was in need of improvements following a “deflating” incident in 2007 caused by a tear. In 2009, funding was approved to upgrade the Vancouver stadium’s infrastructure, plumbing, electrical systems and install a new retractable roof. the upgrade work included concrete cutting with diamond tools in various parts of the stadium and scanning with ground penetrating radar (GPr).

The contractor created 1-inch-wide expansion joints for new roof loads.


Bc Place is a 54,500-seat,

multi-purpose stadium

in Vancouver, British

Columbia, Canada. The

stadium opened in 1983 and is the home of the BC

Lions CFL football team and Vancouver Whitecaps

FC MLS soccer team. BC Place was also the Olympic

stadium during the 2010 Winter Olympics and

the 2010 Paralympics. In January 2007, a tear

occurred in the roof that led maintenance teams

to perform a controlled deflation of the roof. The

tear allowed large quantities of rain and snow

to enter the stadium, which then needed to be

pumped out. The following year, it was announced

that a number of renovations would be made to

the stadium, including the replacement of the

air-supported roof with a retractable, steel frame

roof with cable supports.

The concrete cutting work involved the

modification of 54 existing structural supports for

the installation of new structural supports, almost

500 feet of expansion joint cutting, GPR scanning

of various concrete structures and the cutting and

removal of sections of the concrete support slab for

the playing field to accommodate a new drainage

system. Precise and flat edges were required for

the new mounting plates and brackets, and cutting

could not interfere with other existing concrete

structures that were to remain. Access in many

areas was tight, so detailed planning of dust and

water controls were required to guard against

these hazards building up while cutting.

PCL Constructors Westcoast Inc. of Richmond,

British Columbia, was appointed the general

contractor for the work and immediately was given

a tight timetable. The Canadian Football League’s

Grey Cup Championship Game is to be played

under the new roof on November 27, 2011. Prior

to this date, the BC Lions are scheduled to play

their first home game at BC Place on September

30, with a Vancouver Whitecaps FC game following

on October 2.

The general contractor began looking for a

specialty contractor that had the range of services

to scan structures for hazards, perform accurate

concrete cutting and demolish existing structures.

PCL Constructors chose CSDA member Pacific

Blasting & Demolition Ltd. of Burnaby, British

Columbia, to complete the cutting and coring

elements of the structure and playing field slab.

However, Pacific’s scope of work quickly expanded

to include coring 6,000 anchor holes for the new

upper deck support system. The anchor hole work


included scanning the locations with GPR. These

core locations required scanning to locate and avoid

damage to existing structural steel. GPR technology

works by passing radar waves through the concrete

via a radar antenna. As the wave encounters

structural steel and other targets like PVC conduits,

it reflects back data that is converted to images

of these targets. The target depth and location is

transferred to the surface of the concrete.

“The project at BC Place was very high-

profile and we were very pleased to be cutting

there,” said Peter Alvernaz, division manager

for Pacific Blasting & Demolition Ltd. “As

the work progressed, we recognized the

opportunity to expand our offering on site

by providing the scanning services to the

general contractor.” Scanning was performed

by Pacific’s trained operators utilizing the

StructureScan Mini manufactured by CSDA

member Geophysical Survey Systems, Inc.

(GSSI). As the cutting contractor’s role on site

expanded to additional cutting and coring, so

did the scanning opportunities. To the interior

of BC Place, new supports were to be installed

on the structure that required mounting

plates on existing interior walls and concrete

beams. Each location required scanning. In

an effort to ramp-up scanning efforts, Pacific

purchased additional scanning equipment,

including a StructureScan Optical System,

also manufactured by GSSI. The scanning team

covered several hundred locations over the

course of 14 months.

While the demolition work started to

expose the concrete columns and slabs for

removal, the first concrete cutting task was

to isolate the slab on the playing field from

the rest of the ground floor slab. A 3,000-foot

perimeter cut was made around the playing

field at a depth of 7 inches. This made sure

the heavy equipment would not strain the

slab on grade outside of the playing field.

Two 40-horsepower slab saws from Dimas and

Husqvarna were used to cut the perimeter.

Some seating areas were removed to

expose a total of 54 areas required for the new

column struts and column upgrades. One full-

time scanning technician scanned the precast

slabs to identify rebar and pre-stressed cables

using the GSSI StructureScan Mini. Next, three

crews of three operators set up to cut and

remove the sections of the precast bleacher

slabs to expose the supporting raker beam.

These beams act as supports that prevent

columns or roof structures from sinking or

sagging. It was important for the contractor

to get as many of these openings completed

as possible before the old roof was deflated

and the erection of the new roof started.

The raker beams would be taking on added

responsibility, as the new steel columns would

be erected at the tip of each beam.

Pockets were cut, consisting of sections cut

from the end of the bleacher slabs around an

existing support column. The sections were 5

feet long by 3 feet wide and 5 inches thick with

a step. Crews used Longyear 360 and GDM

Plenum walls were removed under the raker beams around BC Place.

Column strut pocket openings were cut and broken out. Core drills were employed to create holes in the plenum walls.

wall saws, some fitted with 40-inch-diameter

blades. The corners were core drilled for the

overcuts to within 0.25 inches of the bottom

of the slab. With the openings being high over

the top of the stadium glazing, the cores could

not be dropped and the concrete could not

be jackhammered. The 1,000-pound pieces

were plate bolted before the final cut, and

craned out of the pocket when free. Where

cranes could not be employed, chain hoists

were used. Each opening took four hours to

mobilize, core, cut and remove.

As the first crew completed work on the

pockets, operators were re-employed to work

on the Husqvarna wire saw with a 100-foot

run of diamond wire. Thick concrete walls

formed air plenums for the fan intakes that

supported the dome roof. With the plenum

now redundant, 25-foot-high sections of the

plenum wall were removed at 16 locations

to provide space to support the raker beams.

Sections weighing 4,500 pounds and measuring

5 feet long by 3 feet wide and 2 feet thick

were removed with chain hoists and lowered

down to the slab before being taken away by

forklift. There were 80 pieces removed for a

combined total of 360,000 pounds. In some

areas, wire sawing was not practical, so drilling

was the only viable option. The contractor had

two four-man crews working for five days at

each location to finish this cutting work.

Where there were no plenum walls, the

raker beam upgrade required an opening

through the slab. A wire saw fitted with 50

feet of wire cut the 2-foot by 1-foot openings

through a 3-foot double tee pre-stressed slab.

In addition, plenum walls were core drilled

for seismic dampers at 32 locations to assist in

the creation of door openings and electrical/

mechanical holes.

The 14-story columns for the new roof

structure are supported by an existing

concrete ring beam. The new columns had

to be installed in pairs and directly across

the stadium from each other to keep balance

on the ring beam. The cutting contractor

arranged 54 mobilizations, coordinating

with structural upgrade crews below the ring

beam and column installation crews above.

This was a challenge for Pacific, but the work

progressed well at all stages. Working in the

stadium around several other subcontractors,

the team from Pacific had to be conscious of

potential safety hazards and make sure all

items of personal protective equipment were

worn at all times. Coordination was the key to

ensuring all trades were aware of each other’s

activities. This meant moving to convenient

locations to keep ahead of critical tasks.

Cranes were used both to lower the old roof

cables and to erect the new steel columns

and cables. Daily meetings with other trade

supervisors helped to ensure that there were

no delays. Fall protection plans were put in

place for all concrete removal that created

fall hazards.

To complete the cutting, demolition and

scanning work at BC Place, Pacific Blasting

& Demolition Ltd. used a 40-horsepower

diesel slab saw, a 360 wall saw and a wire

saw from Husqvarna. Also, a slab saw from

Dimas was used along with a wall saw from

GDM. A pneumatic drill was custom fabricated

by the contractor that used a bencher drill

mounted on an air cylinder with specialty

track mounts and a vacuum attachment. In

addition, a 1-inch-wide, 26-inch-diameter

wall saw blade was manufactured by Cyclone

Diamond Products. To conduct GPR scanning

on the concrete structures of the stadium, a

StructureScan Mini and StructureScan Optical

System manufactured by GSSI was used.

The cutting work remained on schedule,

which enabled crews to erect the support

beams on time and meet budget. As the

contract came to a close, Pacific’s operators

were given additional cutting tasks. Core

holes were drilled to provide duct openings

for the electrical and mechanical trades. The

contractor began work in March 2010 and

completed all cutting by August of 2011.

“I believe we were chosen to do the work

at BC Place due to our ability to coordinate

with other trades and our reputation to

deliver on time. This was a monumental

project for Pacific Blasting & Demolition Ltd.

We are extremely proud of the results our

supervisors and crews accomplished on this

project,” concluded Alvernaz.

The upgrade at BC Place remains on

schedule for an official opening at the end

of September 2011. The cutting and demoli-

tion work performed by this CSDA member

helped raise the roof at the venue.

c oncrete cutting with diamond tools is being used on a number of

projects throughout Louisiana to help the state recover from the

damage caused by Hurricane Katrina in 2005. transport links and

infrastructure were rebuilt or repaired as soon as possible following the disaster.

While a new twin span bridge was constructed to reconnect two cities in

eastern Louisiana, the old damaged bridge spans remained. Having been

marked for demolition, these damaged concrete spans required subtle and

precise cutting to safely remove them from the area. the work began in april

2011 and consisted of around 100,000 linear feet of sawing, including cutting

depths of up to 40 inches.

all sawsCutting Contractor Aids I-10 twin Span Bridge Replacement

The Interstate-10 Twin Span Bridge runs

north and south across Lake Ponchartrain and

links Slidell to New Orleans. The original spans

were opened in 1965 and consisted of 433

65-foot concrete spans. Each span was two

lanes wide and had clearances of 8.5 feet for

most of the bridge, with a 65-foot clearance

at the bascule bridge section. The new twin

span bridge is located just 300 feet east of the

old spans and has three lanes running in each

direction. It stands 30 feet above the surface

of the lake with an 80-foot-high section near

Slidell. Each span is 60 feet wide.

The selective saw cutting of the old twin

span bridge sections involved the demolition,

removal, processing and recycling of concrete

decks, pier caps and beams. This was part of

the Louisiana Department of Transportation’s

recycling program to reuse damaged structures

for revetment shore protection systems. To

comply with parts of the program, all slurry

and waste material had to be kept to an

on deck

1 4 | septeMBer.11

Saw cutting allowed the contractors to

contain and control more debris as opposed

to traditional breaking methods. In addition,

the methods used by the cutting contractor

provided greater levels of safety for employees

and caused less vibration than breakers and

wrecking equipment. The bridge sections were

already damaged, so high levels of noise and

vibration could have caused the sections to

crumble into the lake and injure operators.

The first tasks for the team from Concrete

Cutting & Breaking involved deck slab sawing

and cutting the diaphragm splits. This cutting

work was started in advance of the critical

path selective demolition sequencing. The saw

cutting of deck and diaphragms maintained

deck egress access and use. Wire saw runs were

then set up to cut the pier caps. These sections

were at elevated heights, so precise sections

and weights had to be determined before

cutting commenced. The weight of the cut

sections had to meet the lifting capabilities

of the cranes on site.

absolute minimum and such materials had to

be contained and disposed of in line with state

regulations.

The use of diamond tools to cut the

damaged bridge spans was specified, as this

would reduce the possibility of debris falling

into Lake Ponchartrain. In addition, the speed

of these cutting techniques would be more

efficient than breaking and burning rebar.

The demolition division of NASDI, LLC, based

in Waltham, Massachusetts, was chosen as the

general contractor for the project by parent

company Great Lakes Dredge and Dock

Company of Oak Brook, Illinois. NASDI then

contracted CSDA member Concrete Cutting

& Breaking Co. to perform the cutting work.

“We had to use several cutting techniques

to complete the job,” said Ed Gushwa, project

manager for Concrete Cutting & Breaking’s

southeast region. “There were areas with limited

access that were between 30 to 70 feet above

the water line. Wire sawing was best suited for

these areas, but on top of the decks we used slab

saws fitted with large diameter blades.”

Operators and equipment from the

company’s Florida and Michigan locations

were transported to Louisiana as they are

specialized in highway and bridge work. The

work area was set up at the bridge, which

included a 300-ton crane and a work barge to

move and off-load the cut sections of concrete.

The crane also moved trucks, saws and support

equipment onto the deck elevation.

The cutting team slab sawed longitudinal

deck cuts between the deck and the

American Association of State Highway and

Transportation Officials (AASHTO) steel beams

below for the total length of the bridge.

Operators made four cuts that each measured

over 5 miles long to depths of 6.5 inches. The

cuts were made short of full depth penetration

to contain the slurry produced while cutting.

It took four operators 14 weeks to complete

the four cut lines using CC120 slab saws from

Diamond Products. The next job was to make

parapet plunge cuts into barrier wall splits.

This would create smaller wall and deck cut

sections for the lifting and removal operation.

Pier caps were cut into sections by diamond wire sawing.




It was then time for Concrete Cutting &

Breaking to perform deep cuts on the four

end and four intermediate diaphragms for

each longitudinal deck cut. There were a

total of eight diaphragm splits per span and

433 spans in each direction on the bridge.

Operators completed transverse deck cuts with

slab saws at the channel spans. Four of the

cuts measured 100 linear feet, two measured

200 linear feet and the other spans cut were

around 8 feet for the cut and lift operation.

Slab saws from Diamond Products were fitted

with 91-inch-diameter blades from Husqvarna

and Diamond Products for the deep cuts.

upon completion of the slab sawing work,

the cutting contractor began setting up pulleys

and equipment for the wire sawing of the

pier caps. The 120-horsepower tractor rig wire

saw was used to make vertical splits from the

floating barge deck through the cap elevation.

The splits were approximately 45 square feet

per pull. Each pull took 1.5 hours to complete

before the cut concrete sections were removed

by crane.

Cutting work on bridges always has its

challenges. Access to the work area on the

I-10 Twin Span Bridge was restricted due to

The wire saw and pulley setups were placed on floating work barges.

Wire saw pulls were completed using a 120-horsepower rig.

Support columns for the pier caps were broken for removal.

each end being detached from the shore

line. Staging areas for the job were set up on

floating barges and all trucks, saws, storage

containers, trailers and support equipment

had to be lifted via crane on and off the bridge

deck in the middle of Lake Ponchartrain.

The aggregate used to construct the bridge

components also provided the cutting

contractor with a challenge. The concrete was

tough to cut and the bridge components were

heavily reinforced with steel. Representatives

from CSDA member companies Diamond

Products, Diamond Tools Technology and

Husqvarna were on hand to provide technical

support and suggest solutions.

The containment of slurry was of concern

right from the beginning of the job. The

bridge engineer and local DOT water quality

personnel reiterated the state’s program to

minimize slurry and waste materials entering

Lake Ponchartrain. By using wire sawing

techniques and avoiding full penetrative cuts,

the cutting contractor was able to keep slurry

levels to a minimum.

To complete this large job, Concrete

Cutting & Breaking used 10 120-horsepower,

V-6 slab saws manufactured by the company

and Diamond Products. The contractor also

manufactured four 120-horsepower and four

60-horsepower parapet plunge deep cut saws,

two 120-horsepower tractor rig wire saws

and a 1,500-gallon water tanker trailer and

pump system. Diamond Products supplied the

120-horsepower deep cut saw for the deck

cutting. Blades ranging from 26 to 91 inches in

diameter were supplied by Diamond Products,

Diamond Tools Technology and Husqvarna,

while diamond wire was also supplied by

Husqvarna and Diamond Tools Technology.

The cutting work on the I-10 Twin Span

Bridge began in April and finished in August.

The work was completed on time and within

budget.

“We have an ongoing relationship with

this customer and have completed numerous

projects of similar scope for NASDI in South

Carolina and Florida, “said Gushwa. “Our

reputation for successfully completing

complex selective demolition projects, not to

mention our staff of experienced employees

within all levels of the company, is what

convinces companies to use us.”

Cut sections were rigged and lowered to the barge by crane.

Hydraulic Versus High Frequency— Wall and Wire Saw Technology in the Concrete Sawing and Drilling Industry

w hen cutting large concrete areas, a wall or wire saw

can be the ideal piece of equipment for the job. Wall

and wire saws have typically been powered by hydrau-

lics, but now contractors have a choice between hydraulic or high

frequency machines. High frequency technology has been around

for over 30 years, though it took some time for this technology

to become fully developed. Products were limited and not readily

available in the marketplace, therefore it took a while to break

into the hydraulic-dominated construction industry. It was not until

the 2000s, when high frequency equipment was more refined,

that acceptance of this technology grew. Since then, various high

frequency products have emerged into the concrete cutting and

drilling market, including high frequency wall and wire saws. It

is important to look at the differences in hydraulic and high fre-

quency wall and wire saws to understand how each operates, their

maintenance needs and modern techniques. This will enable cut-

ting contractors to best determine which is better for a particular

project or for their fleet.

operation and BeneFitS

Wall saws are built to cut through reinforce concrete, brick

and other building materials to make openings, while wire saws

are used to cut through larger concrete structures such as bridges,

foundations and very thick walls. The end results are the same—pre-

cise, efficient cutting—but it is how hydraulic and high frequency

systems work to achieve the end result that is the difference.

converterS and power packS

High frequency wall and wire saws produce enough power

to move the blade or wire through the material to be cut. When

using a high frequency product, the power supply is converted into

greater power through a high frequency converter. For example, a

480-Volt, 60-Hertz power supply can be converted into 400 Hertz

by a high frequency converter. There are a lot of different ways

to measure power, but the most precise way is to measure at the

blade shaft of the saw head. This provides contractors with a true

measure of power in the system.


When comparing high frequency to hydraulic, it is important to

note a larger hydraulic power pack is needed to achieve the same high

power output as a high frequency converter. Various connections and

hoses in the hydraulic power pack reduce power transfer efficiency,

therefore less power is supplied to the saw head. A hydraulic system

also runs the risk of a hose breaking and oil spilling on the jobsite,

making clean-up necessary and difficult. A high frequency system does

not use oil, creating a cleaner working environment. Furthermore, a

high frequency electric converter is safe to use around a minimum

amount of water.

Size and Setup

Wall and wire saws are not only moved to and from a jobsite, but

are also moved around the site depending on the type and quantity of

the material being cut. Their designs must be able to facilitate adjust-

ments and movements. Due to wall saws having many components,

most cannot be easily carried around. However, some high frequency

wall saw systems are light enough to be carried. Wire saws are typi-

cally equipped with wheels to allow for easy transportation, as they

can be heavy pieces of equipment. The difference is in the power pack.

Most high frequency converters are about the size of a small suit-

case and can be easily carried. This makes them easy to transport to and

from the jobsite as well as around the site when required. Hydraulic

power packs need to be transported on wheels and can weigh any-

where between 300 and 2,500 pounds. As a result, these power packs

are more cumbersome to move around the jobsite.

Some hydraulic and high frequency wall and wire saws are oper-

ated by remote control. Normally connected with wires, they enable

the operator to move around the job and maintain a safe distance

from the cutting area, within the limits of the wire. However, several

high frequency models have been introduced that have wireless tech-

nology, allowing operators more freedom and eliminating the chance

of them becoming tangled in the wire.

Another high frequency advantage is that high frequency con-

verters use one cord instead of the average seven hydraulic hoses that

connect the unit to the saw head. This makes set-up of high frequency

systems simple and quick, as there are less components to assemble.

maintenance

Since high frequency systems use different technology than

hydraulic saws, they have to be maintained differently.

Hydraulic power packs are tough. These units can be thrown

around yet start up again. High frequency motors need to be handled

with more care, as the electric components could break. As with any

type of system, a high frequency motor will last for a long time, pro-

viding it is properly maintained. Many contractors feel hydraulics are

more reliable because they do not have to be handled with as much

care. However, a well-treated high frequency machine can be just as

rugged and last longer than its hydraulic counterpart.

High frequency equipment is built with electronic components

and therefore operators have to take precautions when performing

maintenance. If clean-up is done at the end of each day when debris

is fresh, it can save time the next day after everything has dried. The

rule of thumb is, “taking two minutes at the end of the day can save

you 20 minutes the next.” Taking two minutes to flush the system and

make sure everything works will go a long way in ensuring the system

will work day after day. When there is a problem, changing out electri-

cal components as opposed to hydraulic parts makes repair work easier.

Often electrical components can be identified, removed and replaced

easier than hydraulic parts.

modern techniqueS and equipment

Wall saws use a track with a saw head attached, and the saw head

is moved up and down the track to cut the material. Wire saws can be

set up in an infinite number of ways—imagination being the only limit.

With the use of swivel pulleys, the saw can be set up to cut in any direc-

tion, either pulling or pushing the wire through the material. Wall saws

and wire saws have their specific applications, and in some cases one can

be used to complement the other.

Contractors like the ability to use both of these machines for vari-

ous projects and will bring both types of saws to a job site. High fre-

quency wall saws are now on the market and can be coupled with high

frequency wire saws, giving the operator a flexible saw in one single

system and saving the contractor from having to transport two sepa-

rate machines. This type of high frequency wire saw uses the same wall

saw unit, track, remote and power supply as the wall saw; making the

conversion between the two seamless. It is as simple as turning a dial on

the wall saw remote to change between the operation of a wall saw to

a wire saw, and the remote is equipped with software for both. It is best

to use this new companion wire saw when a contractor either has a high

frequency wall saw or is planning on using both frequently.

In general, the concrete sawing and drilling industry entails hard,

dirty, heavy and loud work. Finding new ways to create a better working

environment is the key to the future—not only for operators, but for the

industry as a whole. As technology continues to change, it is important

to learn about these new technologies and see how they will fit into the

cutting and drilling industry. High frequency technology is still classed as

a new addition to the industry, but more and more companies are begin-

ning to explore and use these systems. Many in the industry believe high

frequency technology will be the way to work in the future, and it is pre-

dicted that this technology will move into more equipment categories in

the near future. One thing is for certain; high frequency is here to stay.

The completed concert hall.

A Solid PerformanceDiamond Core Drilling Steals the Show

t he stage was set for one csDa member to put on a show-

stopping performance at a new concert venue in carmel,

Indiana. a specialist core drilling contractor was required to

create over 800 holes in the concrete floor of a concert hall that is

home to Michael Feinstein’s Great american songbook collection,

so that patrons could sit comfortably during events.

A total of 840 holes were drilled in the floors of The Palladium.



The Center for the Performing Arts is a

new entertainment complex located in the

center of Carmel, Indiana, and officially

opened in January 2011. The center includes

The Palladium concert hall, the Tarkington

proscenium theater and a 200-seat theater.

The Palladium acts as a museum and education

center by day and a concert venue by

night. The 1,600-seat concert hall has been

designed with a classical Palladio dome and

the building’s concrete, steel and stone-clad

structure is expected to last 500 years or more.

Approximately 6,750 cubic yards of concrete

were used in the construction of the building.

Acoustics were of great importance to

the design, but so was comfort. A heating,

ventilation and air conditioning (HVAC)

company was contracted to install individual

air diffusers under each seat of the main

concert floor and all balcony levels. This would

provide the audience with a comfortable room

temperature and minimize noise from the

HVAC system.

Holes were drilled 8.5 inches in diameter through 6-inch-thick concrete floors.

2 2 | septeMBer.11

Poynter Sheet Metal contracted CSDA member The Concrete Surgeons, also of Indianapolis,

to core drill 840 holes in the main floor and balcony levels with diamond tools. The majority of

the holes had to be 8.5 inches in diameter with some smaller holes of 6 inches on the balcony

levels. All holes had to be drilled through a 6-inch-thick reinforced concrete floor and each hole

was to be positioned to the exact specifications of the HVAC contractor. Work was to begin at

the end of August 2010 and all drilling work was to be completed in three weeks.

“There were strict dimensional tolerances for these holes and we had to maintain the

structural integrity of the rest of the building as well. The holes had to be positioned precisely

under each seat so that the air diffusers could be correctly installed,” said John Serban, owner

of The Concrete Surgeons. “These were all reasons why we were selected, as our core drilling

techniques met all of these requirements.”

The layout of the holes was marked out by Poynter Sheet Metal so that the cutting contractor

could get to work. The team from The Concrete Surgeons began by core drilling holes in the

6-inch-thick reinforced concrete concert hall floor. Of the 626 holes made, 68 had to be drilled

through a 2-inch layer of rigid fiberglass insulation batts. Each hole measured 8.5 inches in

diameter and took an operator around 15 minutes to drill. A 1,000-hertz, DD350 electric core

The holes were specifically positioned under seating areas for the installation of HVAC systems.


drill supplied by Hilti and one Shibuya core

drill supplied by Diteq Corporation were used

to create the holes. The drills were fitted with

core bits from Diamond Products. It took two

operators 16 days to complete all of the 626

holes in the floor of the concert hall.

The contractor then moved up to the

second and third balcony levels of the hall

to continue the drilling work. Operators core

drilled 60 8.5-inch-diameter holes through the

6-inch-think concrete balcony floors, before

completing the drilling work by drilling 38 holes

that were 6 inches in diameter. The Concrete

Surgeons created a total of 106 holes in the

balcony floors over the course of nine days.

Containing slurry and debris from the

core drilling work was very important on

this job. Had any slurry seeped through the

floor openings, damage was possible to the

fiberglass batts underneath the concrete slab.

The Concrete Surgeons used trap rings around

the core bits and the team vacummed as it core

drilled to control the slurry. A wet vacuum was

used to collect the 577 gallons of slurry created

during the course of the job.

The core drilling work at The Palladium

concert hall had a fixed schedule of three weeks

for completion. The cutting contractor assigned

two core drill operators to work eight-hour shifts

to complete the required 840 holes. The holes

were completed one full day ahead of schedule

due to the contractor’s ability to select the right

core bit for the job, as well as the holes being

drilled quickly, efficiently and precisely.


The main concert hall was cordoned off, while operators used harnesses when working on the balcony levels.

2 4 | septeMBer.11

Working in internal areas close to other

subcontractors, operators were trained and

prepared for all potential safety hazards.

The cutting area of the main concert hall

floor needed to be cordoned off to prevent

anyone from stepping in the holes and injuring

themselves. On the balconies, operators used

full-body harnesses with lanyards for fall

protection, while all employees were provided

with the necessary personal protective

equipment to complete the work safely.

The team from The Concrete Surgeons

used the Hilti and Shibuya core drills with

diamond core bits to create all of the specified

holes. Slurry was collected in a wet vacuum

from Crusader. A total of 840 holes were drilled

through 6-inch-thick reinforced concrete

floors. In addition, some of the drilling

locations were on a slope and some holes had

to be created by also drilling through 2-inch-

thick rigid insulation fiberglass batts.

Because the core drilling work was

completed ahead of schedule, The Concrete

Surgeons was awarded additional jobs at

the venue, including the core drilling of

10-inch-diameter holes through foundation REVIEW AND COMMENT ON THIS ARTICLE AT:

Save a Life with Hands-Only™ CPR

core HEalTH

most of us understand the importance of having formal

training in emergency response, such as first aid or cardio-

pulmonary resuscitation (CPR). However, most workplaces

still lack an abundance of trained healthcare providers. This has led

the American Heart Association (AHA) to issue new guidelines that

promote a life-saving procedure anyone can do, even without training.

Hands-Only™ CPR is now being promoted by the AHA as a viable

method in treating heart attack victims and will potentially save thou-

sands of lives. Cardiovascular disease, which can cause heart attacks,

is responsible for one out of every three deaths in the united States.

This equals one death every 39 seconds. A 2010 AHA report showed

that effective bystander CPR, or Hands-Only™ CPR, provided immedi-

ately after sudden cardiac arrest can double or triple a victim’s chance

of survival.

Hands-Only™ CPR removes the responder’s responsibility of per-

forming an airway check and giving breaths to the victim, so that the

steps are easier to follow. This technique should be used when a co-

worker suddenly collapses or is found unresponsive.

• Checkforconsciousness.

• Ifthevictimisunconsciousorshowingsignsofaheartattack,

call 911.

• Ifthevictimisnotbreathing,anddoesnothaveblood

• Compressionsshouldbegivenhardandfast,withthe

compression rate at least 100 compressions per minute.

• Whengivingcompressions,allowforcompletechestrecoil.

• Minimizeinterruptioninthecompressions.

Survival rates for heart attack victims receiving Hands-Only™ CPR

are similar to survival rates for victims receiving traditional CPR. This

is a simple procedure that should be taught to all employees in the

workplace, whether workers have received formal training or not.

Besides Hands-Only™ CPR, there are other steps workers can take

to help a co-worker who may be having a heart attack. Noticing the

risk factors and signs of a heart attack can lead to early detection and

early response, decreasing the effects of the heart attack and raising

the odds of survival. Risk factors include:

• Poordiet

• Lackofexercise

• Obesity

• Smoking

• Age

• Stress

• Familyhistoryofcardiovasculardisease

Signs of a heart attack include:

• Sudden,intensechestpain,possiblyradiatingtothejaw,left

shoulder or arm

• Excessivesweating

• Nauseaandvomiting

• Shallow,rapidbreathing

• Bluishskin,especiallyaroundthelips

Any worker exhibiting signs of a heart attack can be given one adult-

strength aspirin or two low-dose aspirin if they are not allergic, providing

they are still conscious and able to swallow. Aspirin works quickly in the

bloodstream to prevent the formation of blood clots, which can decrease

the severity of the heart attack.

More information, including a video demonstration, can be found on

the AHA’s Hands-Only™ CPR website, http://handsonlycpr.org. The impor-

tant thing to remember is that two steps–calling 911 and performing

chest compressions–may save a co-worker’s life. Concrete cutting company

owners, managers and workers should all familiarize themselves with this

simple procedure.

How To Best Think About Loans For Your Business

By Ami Kassar

the Business of BusinEss

one important lesson learned from the economic crisis we have lived through, is not to

jump into debt head-first. Debt can, and should, be an important part of your business, but you have to think about it carefully and thoughtfully. a bad loan decision can send you and your sawing and drilling business spiraling out of control.

If you think that you might need a loan,

the first step is to sit down with a pencil and

paper and ask yourself some important ques-

tions. First, how much money do you think you

need to borrow and for exactly what purpose?

You should challenge yourself to see if there

are any creative ways to save on some of the

expenses you are projecting.

Once you have confirmed these numbers,

try to estimate how much money you expect

to make as a result of the loan and over what

period of time. What is your most conserva-

tive projection? Do some math to figure out

what monthly loan payment you can afford. It

is then a good idea to run these figures by an

accountant or financially-savvy friend.

You need to have a good handle on how

much money you really need, and what you

can afford to pay monthly for it, before you

start the process of shopping for a loan. If

you can find a loan product that meets your

budget and you are approved, it is advised to

move forward with process. If not, it is per-

haps time to go back to the drawing board

and rethink your business model.

Now that you have your basic economic

proposition intact, you need to understand

your collateral situation. Collateral is the first

thing most lenders look at when evaluating

a loan. They want to know how they will be

protected and what assets they can recover if

your loan cannot be repaid. The quantity and

quality of your collateral will have a direct and

dramatic impact on what interest rate you can

expect to pay for a loan, not to mention the

loan payment term the lender will offer you.

understanding how much collateral you have

is a good indicator of how much money you

can expect to borrow.

how lenderS calculate collateral

While every lender looks at collateral in

slightly different ways, there are general rules

of thumb that you can use to evaluate your

collateral situation.

For lenders, real estate is always the first

choice of collateral. If you own your own

building or any investment properties, this

is the first area they will look. What happens

first is lenders will take the current value of the

property and automatically deduct 25 percent

from the top line. So if a building appraises

at $1,000,000, for the lenders purposes, they

will consider the building worth $750,000.


What’s next for your business? What new opportunities are ripe for the seizing? What could you do with more knowledge and certifi cation? How far could you go with the right suppliers, the right connections, the right tools and timing? Spend time at World of Concrete and get what you need to build a stronger, more competitive business.

The lender will then deduct the value of any

mortgages you currently have on the prop-

erty, and the balance that remains will be the

collateral they are willing to use. Therefore, if

you already owe $500,000 on this particular

building, the lender will be willing to give

you $250,000 worth of collateral value.

Residential properties follow the same

formula as commercial properties, but with

one exception. In this case, lenders will be

a little more generous in how much they

deduct from the top line. As a general rule,

they will use 20 percent. So if a home is

worth $500,000 they will consider it worth

$400,000. If you have a mortgage of $200,000

on this property, they will consider there to

be $200,000 of collateral value.

Other forms of collateral include equip-

ment, receivables, liquid stocks and cash.

For concrete cutting equipment, lenders will

determine the forced liquidation value of

the equipment and generally lend at 50 per-

cent of its value. If your receivables are with

reputable companies and are for work that

is completed, you can generally expect to

get 80 percent of their value for collateral.

Liquid stocks are generally worth 70 percent

of their current value, and if you are willing

to lock up cash in a CD for the life of a loan

you will generally get 95 percent of its value

for collateral.

In today’s environment, lenders are gen-

erally looking for dollar-to-dollar collateral

value. This means that for every dollar of

collateral you have to offer, they will lend

you a dollar if everything else checks out.

The form of collateral that you have to offer

a lender will often affect what type of loan

you get. Today in the u.S., many small busi-

ness owners are turning to the Small Business

Administration (SBA) and factoring for their

lending needs.

how do SBa loanS work?

SBA loans are one of the most commonly-

misunderstood loans by small business own-

ers across America. There are some key prin-

ciples about the SBA program that every

business owner in the sawing and drilling

industry should understand.

First of all, the SBA is not a bank or a

lender. What the SBA does is provide a guar-

antee or insurance policy for loans to small

businesses. This way, banks will approve small

business loans that they otherwise may not

have considered. The government hopes that

the program will encourage banks to provide

businesses with loans that once may have

been considered a risk. If you take out a SBA

loan, you are borrowing the money from the

bank or the lender. You are not borrowing the

money from the government.

It can be common for small business own-

ers to think that they are not required to pro-

vide collateral for the loan because they are

getting a SBA loan with a government guaran-

tee. Regardless of the guarantee, this is still a

loan and the lender will demand collateral in

order to place a SBA loan. Remember that the

government is offering the insurance policy to

the bank, not to the business. SBA loans can

be a good option for small businesses. If you

cannot get a traditional commercial mortgage

or line of credit from a bank, it is always worth

your time to check if they would be willing

to make the loan with the SBA behind them.

when doeS Factoring make SenSe?

In today’s economy, more and more small

businesses are turning to factoring to help with

their working capital and cash flow require-

ments if they do not have the collateral required

for a SBA loan. Factoring has been around for

a while, but has become much more prevalent

in recent times. unfortunately, many businesses

do not understand it that well.

In a factoring arrangement, the lender

looks at who owes you money for services

completed and essentially buys those invoices

from you. The process is quite simple. After

you have reached an agreement with the

lender (or factor), you send copies of submit-

ted customer invoices to them. Within a couple

of days, the lender will send you an advance

on those invoices, usually about 80 percent of

the total. When the customer sends in pay-

ment, the money is addressed to your company

name but the destination is a new address con-

trolled by the lender. The lender then deposits

the money into an account before subtract-

ing a fee and returning any remaining bal-

ance to you.

Factoring agreements are tricky and often

have many hidden fees. Always get a few

quotes and understand what you are agree-

ing to before committing to one of these

arrangements.

what to watch For in a loan

agreement

Irrespective of the loan you agree upon,

there are some issues that you must pay atten-

tion to at the closing table. Getting a business

loan is not an easy task. The process can often

be emotional and it is easy to become con-

fused. It is important to clearly understand the

loan agreement before proceeding.

Here are five questions you should have

clear answers to before signing on the dot-

ted line.

• Whatwillallofmyup-frontfeesbe?

• Whatwillmyannualcostofcapitalbe

with all fees included?

• Howcantherateschangeduringthe

term of the loan?

• Whatcollateralwillthelenderbetaking,

and with what conditions?

• IfIchoosetogetoutoftheloanearly,

what penalties will I face?

It is absolutely critical that you understand

all of these issues clearly before you sign a loan

agreement. All too often businesses give up far

too much collateral for the loan they received,

then are subject to pre-payment penalties that

were in the small print. This has sometimes

ended with business owners in handcuffs.

It is natural to focus on getting the best

possible rate that you can, but sometimes it

is worth paying a little more in order to have

the flexibility to borrow more money in the

future or to trade one element of the loan

agreement for a better pre-payment penalty

option. You do not have to use up all of your

collateral in one go.

Loans should be designed to give the bor-

rower the most flexibility. Always push your

lender or your advisor to come up with two

very different options for you. The choice and

the differences between the two will help

make sure you are focused on all five of the

above questions.

preventing worker deathS at roadway

conStruction work zoneS

According to the Bureau of Labor Statistics, each year from 2003

through 2007, more than 125 workers died in roadway construction

work zones. Half of these worker fatalities involved the worker being

struck by a vehicle or piece of mobile machinery/equipment.

Through the OSHA and The Roadway Work Zone Safety and Health

Partners’ Alliance, the participants are developing a series of Work Zone

Death Reports for use as Toolbox Talks by workers and employers in

the highway and bridge construction industry. The first three Reports—

Hispanic Laborer Run Over and Killed by a Backing Flat Bed Dump Truck,

Flagger Fatally Injured When Struck by a Car at a Highway Work Zone,

and Three Construction Workers Killed After Being Struck by a Bus in

a Highway Work Zone—describe fatal incidents during which workers

were struck by motorists intruding into the work space or run over by

flatbed trucks backing up within the confines of the work space. Each

report briefly describes a fatal incident, including what happened,

who was killed and what can be done to prevent similar fatalities.

Representatives from the Alliance based the Toolbox Talks on research

two new oSha/cSda alliance BeSt practice

documentS releaSed

The Alliance released two Best Practice documents in July, focusing

on the subjects of scaffold and ladder safety, bringing the total of OSHA/

CSDA safety documents to seven.

Scaffolding forms temporary structures to support people and materials

in the renovation or selective demolition of buildings and other structures.

Serious injury or death can result if sawing and drilling contractors fail to

comply with all applicable safety requirements when erecting, using or

dismantling scaffolding. Ladders are a convenient tool to reach heights,

but they represent a risk to sawing and drilling contractors if not used

in accordance with company and specific site safety specifications or

requirements. These two new Best Practices, CSDA-OBP-1005—Scaffold

t he alliance between the concrete sawing & Drilling association (csDa) and the occupational safety and Health administration (osHa) is now

in its sixth year and continues to educate contractors, prevent on-the-job accidents and injuries and provide vital materials to advance a safe work environment for sawing and drilling professionals. Here is the latest news from the alliance Program.

t he 2011 annual meeting of the

International Association of Concrete

Drillers and Sawers (IACDS) was held

on May 7 in Bruges, Belgium. In an ever-

changing world, it is important to know how

the industry is doing on a global scale and

learn from the knowledge of industry peers.

In attendance were 43 representatives from

Austria, Belgium, France, Germany, Hong

Kong, Japan, Liechtenstein, Russia, Spain,

Sweden, Switzerland, the united Kingdom

and the united States. The association is now

in its 17th year.

The meeting included presentations by

representatives of two Concrete Sawing &

Drilling Association (CSDA) member com-

panies. Phillip Zuzelo of contractor member

Cardinal International Grooving and Grinding

LLC, based in Conshohocken, Pennsylvania,

talked about the benefits of runway groov-

ing and the utilization of trapezoidal-shaped

grooves. Zuzelo explained how the method

of concrete grinding is being used on airport

runways to prevent aircraft from hydroplan-

on concrete roads to increase their life span

was given by John Willis of CSDA manufacturer

member Tyrolit. These methods are seen as a

more eco-friendly alternative to resurfacing

worn concrete roads with asphalt. The results

provide a longer lifespan to the existing

concrete surface and the requirement to

adjust or move existing barriers and signage is

eliminated. Tests show that a road resurfaced

using diamond grinding and grooving can

provide 54% more skid resistance than an

untreated road, thereby reducing road traffic

accidents caused by loss of vehicle control.

Willis then went on to provide details of

a road resurfacing project in the u.K. where

a cutting contractor was able to grind 1,600

square meters (17,222 square feet) per shift

during nighttime closures. The contractor used

two large, 680-horsepower PC6000 road grind-

ers from CSDA member Diamond Products to

complete the work. The grinders were fitted

with 250 diamond saw blades, each measur-

ing 450 millimeters (17.7 inches) in diameter.

Due to the success of grinding jobs like this,

ing in wet conditions. The creation of grooves

on a runway can reduce aircraft braking dis-

tances by providing channels for water to run

off the concrete surface. This increases tire

friction and therefore aids with the braking

of the aircraft.

Statistics showed that, in wet conditions,

a plane with totally worn tires on a grooved

runway achieved better braking than one with

new tires on an untreated runway. When trav-

eling at 70 knots in 2.5 millimeters (1 inch) of

standing water, a plane with worn tires had a

frictional coefficient braking level around 40μ

on a grooved surface. When a plane with new

tires began braking on an untreated runway

in the same test conditions, the frictional coef-

ficient braking level was around 25μ. Further

analysis showed that creating trapezoidal-

shaped grooves in the concrete surface also

reduced tire wear, reduced rubber build-up

and decreased occurrences of chipping or clos-

ing compared with standard grooves.

the u.K. Highways Agency is now reconsid-

ering plans to overlay many of its decaying

road surfaces, and may opt to have these roads

resurfaced using diamond grinding.

Outgoing IACDS President Peter White

of the u.K.’s Drilling and Sawing Association

presented a report about the association’s

activities and achievements over the previous

12 months. These achievements included a

successful 2011 Diamond Award ceremony,

hosted by CSDA and held in Las Vegas during

the World of Concrete show in January.

Bronze, silver and gold awards were presented

to three sawing and drilling contractors whose

projects displayed the best examples of cutting

performance and innovation from entries

submitted. White confirmed that the next

Diamond Award will be open for entries in

the fall of 2012 and the ceremony will be held

at the April 2013 bauma exhibition in Munich,

Germany. To view the winning projects, visit

www.iacds.org and click on the Diamond

Award banner.

IACDS held eight 30-minute seminars on

subjects relating to concrete cutting during

bauma 2010. The goal of the presentations

was to heighten awareness of the concrete

sawing and drilling industry, educate

attendees about new technologies and detail

the possibilities achievable through concrete

cutting. Topics included dry cutting, efficient

cutting for minimal debris and waste water,

underwater wire sawing, hydraulic versus

high frequency cutting equipment, nuclear

power plant work, post-installed rebar and

new market opportunities for concrete

cutters. The seminars proved to be a success

for the international association. An advisory

committee has been formed to plan a similar

format of seminars for bauma 2013, with a

possibility of combining these seminars with

the Diamond Award ceremony.

A representative from each of the national

associations provided the current economic

status for the sawing and drilling industry in

their country. Representatives from Spain,

Russia, the u.K. and the u.S. all reported

reductions in membership and company

bankruptcies, but there have been some

encouraging signs. The Japanese association

felt the impact of the catastrophic earthquake

and tsunami in many forms. However, as

rebuilding work begins, the skilled work of

professional concrete cutters is expected to

be required on Japan’s nuclear plants, dams

and infrastructure. Associations in Austria,

Switzerland and Sweden remain strong,

while the German association continues

to uphold healthy numbers with over 600

member companies. This continued growth is

credited to a benefit given to contractors in

the form of a reduced social tariff levied by the

government, and to a robust construction and

demolition industry in Germany.

IACDS is planning to release a third edition

of its Tolerances and Limits for Construction

Sawing and Drilling in the coming year. Each

of the delegates at the meeting was provided

with a draft copy for review. The last update

of this technical document was released in

2006, and is the second document produced

by IACDS along with Basic Parameters for

Concrete Drilling and Sawing Equipment.

These documents can assist concrete cutters

in their day-to-day work, and can be found

on the IACDS Website (www.iacds.org), in

the CSDA Resource Guide mailed with the

June issue of Concrete Openings or via the

members section of the CSDA Website (www.

csda.org). These documents are also available

to members of other national associations in

electronic paper copies.

White, having served his two-year term as

president of IACDS, now makes way for newly-

elected IACDS President Jose Blanco of the

Spanish Association of Technical Demolition,

Cutting & Drilling. Blanco will also serve a

two-year term as president before one of the

concrete cutters of the world unite

two new vice presidents, Norikazu Shibuya of

Japan or Lars Sandstrom of Sweden, is elected

as president in 2013. The 17th annual general

meeting of IACDS has been scheduled to

coincide with CSDA’s 40th Annual Convention

and Tech Fair in Maui, Hawaii. The convention

will run from March 4 to 9, 2012 with the

international association meeting taking place

on March 6. For more information, read our

In april of 2011, a project commenced that involved the removal of almost 5,000 feet of steel-reinforced concrete posts and railings at the Blue Heron Bridge on the southeast coast of Florida. the posts required precise cutting so that new decorative railings and light fixtures could be installed and give the bridge a much-needed facelift. a local csDa contractor member was given the opportunity to be part of the renovation work.

rail good cutting

the job consisted of removing 4,830 feet of existing

railings and cutting 860 posts on both the eastbound

and westbound sides of the Blue Heron Bridge, which

connects Riviera Beach and Palm Beach Shores near the

coast in southeast Florida. The bridge has around 23,000

motorists cross it every day. The existing reinforced posts measured 10

inches wide by 10 inches thick and needed to be detached from the

brush curb. The removal of these posts would allow for the installation

of the decorative railings.

The main challenge facing the chosen contractor was to contain

all debris and minimize the amount of slurry created by cutting, as

the bridge is located over a waterway. The cuts had to be precise

so that the new decorative railings could be placed correctly. It was

also important to avoid high levels of vibration during the work to

maintain the structural integrity of the existing bridge span. Based

csda member cuts Bridge for new decorative railings

The eastbound side of the Blue Heron Bridge had 2,415 feet of concrete railings that required cutting.



on these specifications, the general contractor for the project—H&J

Contracting of Wellington, Florida—had to find a concrete cutting

contractor that had the skills and equipment to complete the work.

H&J Contracting awarded the cutting work to CSDA member ABC

Concrete Cutting – South Florida of Pompano Beach, Florida, a division

of Ohio Concrete Sawing and Drilling, Inc. Joe Bland, vice president of

ABC’s Pompano Beach office, stated, “Our past performance with the

general contractor was the determining factor when we were chosen

for the Blue Heron Bridge work. It was up to us to perform well on

this job and maintain our solid reputation,” he said.

The team from ABC began its first phase of work by cutting the

eastbound posts and rails flush with the brush curb. This included

cutting 2,415 feet of concrete posts and railings. The second phase

of the work, namely the westbound posts and railings, will begin in

September 2011. The contractor used an innovative technique to make

the cuts. A 360 wall saw by Longyear was attached to the front blade

of an electric mini excatvor. First, operators made 200 vertical cuts in

the railings, 14 feet on center, using hand saws custom fabricated by

ABC Concrete Cutting – South Florida. Each cut took around 10 minutes.

Once the vertical cuts had been made, the cutting team proceeded

to position the mini excavator with wall saw attached to begin the

horizontal flush cuts. The cuts were made at the brush curb to detach

the railings from the curb. The posts and railings were attached to a

Case 590 back hoe with lifting chains and straps as they were cut. This

made sure the concrete sections did not fall from the bridge into the

water and allowed the contractor to lift the pieces from the cutting

area onto a truck for removal. It took three weeks to complete the

2,415 feet of horizontal cutting.

The next task for operators, was to score cut and chip 11 trenches

measuring 5 feet long by 2 feet wide to a depth of 8 inches. These

trenches were required for new light posts to be installed on the bridge.

Some of the specified cutting areas in the

bridge deck and cantelevered sidewalk

contained reinforcing rebar, so operators

had to be prepared to encounter this

rebar while cutting and avoid severing

any of it. It took two operators 11 days

to create the 11 trenches.

ABC Concrete Cutting—South Florida

also performed some core drilling on

the Blue Heron Bridge. Operators used a

Weka core drill from Diamond Products

to create 2-inch-diameter holes 2.5 inches

deep over vertical rebar. The operators

then chipped out any remaining concrete.

This was done to allow the general

contractor to burn steel and epoxy holes

to eliminate delamination of existing

steel and concrete.

While cutting, the contractor encoun-

tered heavy reinforcement in the con-

crete. Each post on the bridge contained

#4 and #6 rebar, so operators had to

adjust cutting speed and monitor the

force applied to the saws to get the best performance out of the dia-

mond blades and bits. Another obstacle that ABC had to deal with, was

that approximately 20 percent of the bridge was missing its sidewalk.

This portion of the sidewalk had been removed by H&J Contracting for

replacement. This process had left a rough, uneven surface, so operators

used hand saws to perform the flush cuts until the team reached a smooth

surface and could switch to the wall saw attachment.

As specified, the contractor had to come up with a way to contain

debris and minimize slurry created on the job. A catch basket was

fabricated by the general conrtractor and installed to stop rubble from

falling into the water below, especially while chipping the 11 trenches

for the light posts. The catch basket was made of steel and expanded

metal. The basket measured 4 feet long, 3 feet wide and was 3 feet deep.

As the cutting work involved the removal of posts and railings,

all employees were required to wear safety harnesses while working

on the bridge. Worker harnesses were attached to temporary barrier

A wall saw was attached to the front blade of a mini excavator to cut the railings.

Horizontal flush cuts were made using the wall saw attachment.

walls to prevent falling the approximate 100

feet into the water below. The contractor

fabricated custom hardware that allowed

quick detachment and relocation of safety

cables to and from the barrier walls.

The use of hand saws were necessary

while the cutting team worked on areas of

the bridge where the terrain was uneven and

operators were unable to apply the mounted

wall saw. When the team reached smooth

terrain, shop personnel attached a track-

mounted saw and associated equipment to

the mini excavator. This technique greatly

reduced operator fatigue and reduced the

time required to complete the cutting work.

In total, ABC Concrete Cutting – South

Florida cut and removed 430 concrete posts

measuring 10 inches by 10 inches from the

brush curb and made 200 vertical cuts in the

post rail. They also performed 2,415 linear

feet of cutting to remove the 12-inch-wide by

12-inch-thick concrete rails on the eastbound

side of the bridge. Operators then used Weka

core drills to create 2,580 2-inch-diameter

penetrations measuring 2.5 inches deep over

exposed re-bar. To create the 11 trenches for

the installation of the new light poles, 5-foot-

long by 24-inch-wide cuts were made 8 inches

deep in the bridge deck and sidewalk.

The scope of work was completed on

schedule without damaging existing utilities

or areas of the bridge that were to remain as

built. “The performance of our operators on

this phase of the job matched expectations,

even with the hand-held aspects of the cutting

work,” said Bland. “This resulted in a high level

of satisfaction from both the management of

ABC and H&J Contracting.” The contractor

will now turn its attention to the westbound

side of the Blue Heron Bridge, consisting of

another 2,415 feet of cutting. When complete,

operators will have cut 4,830 feet of concrete

at the job site.

Operators also score cut and chipped out 11 trenches, each measuring 5 feet long.

In total, the contractor cut and removed 430 concrete posts to remove the railings.

For the Record—OSHA Recordkeeping and Reporting Requirements and State Variations

By Mark A. Lies II and Elizabeth Leifel Ash

today, OSHA regulations govern day-to-day operations and have

a direct effect on employee safety. As a result, it is easy for

OSHA’s more prosaic recordkeeping and reporting requirements

to get lost in the shuffle. However, OSHA can issue citations to

employers for failing to follow recordkeeping and reporting rules, just

as it can for machine guarding or lockout/tagout violations.

In 2009, OSHA introduced a National Emphasis Program (NEP) target-

ing injury and illness recordkeeping on the OSHA 300 Log, designed to

expose violations of recordkeeping regulations. While many employers

will not be subjected to a NEP recordkeeping inspection, even a routine

OSHA inspection will now focus on recordkeeping. It is critical, there-

fore, for employers to keep up with changes to OSHA’s recordkeeping

and reporting requirements and to be aware of state-specific variations

depending on where the employer does business.

injury and illneSS notiFication requirementS

Federal

Part 1904 of OSHA’s regulations contains the employer’s obligations

with respect to recordkeeping and reporting of occupational injuries and

illnesses. under the current rules, an employer must notify OSHA within

eight hours of the death of an employee from a work-related incident,

or the in-patient hospitalization of three or more employees as the result

of a work-related incident.

Recently, OSHA announced a proposal to revise its injury and illness

notification requirements. The proposed revisions would require employ-

ers to notify OSHA within eight hours of any work-related in-patient

hospitalization, regardless of the number of hospitalized employees,

and within 24 hours of an amputation. This proposed revision would

result in a significant increase in the number of cases that would require

notification to OSHA. Because an OSHA inspection is often triggered

by an employer’s notification of a fatality or catastrophe, an increase in

the number of “reportable” events would also increase the number of

OSHA inspections. OSHA is accepting comments on the proposed rule

through September 20, 2011. A copy of the proposed rule can be found at

http://www.gpo.gov/fdsys/pkg/Fr-2011-06-22/html/2011-15277.htm.

State

Notwithstanding federal regulations, many states operate their own

occupational safety and health programs and have varying injury and ill-

ness notification requirements. For example:

• Washington—Employersmustnotifythestateagencywhentwoor

more employees are hospitalized due to a work-related incident.

• CaliforniaandUtah—Employersmustreportallseriousinjuriesto

the respective state agency.


• Kentucky—Employersmustreportany

amputation suffered by an employee

within 72 hours of the incident.

injury and illneSS recordkeeping

In addition to reporting fatalities and catas-

trophes, OSHA requires employers to maintain

an OSHA 300 Log for all work-related illnesses

and injuries that meet any of the following

criteria:

• Theemployeewasoffworkforoneor

more days, excluding the date of the

actual injury or the onset of illness,

because of the injury or illness

• Theemployeeexperiencedoneormore

days of restricted duty as a result of the

injury or illness

• Theemployeereceivedajobtransferasa

result of the injury or illness

• Theemployeereceivedmedicaltreatment

beyond first aid

• Theemployeeexperiencedalossof

consciousness

• Theemployeeexperienceda“significant

injury or illness” diagnosed by a physician

or other licensed health care provider

The purpose of keeping a work-related log

of injuries and illnesses is to highlight potential

workplace hazards that lead to severe injuries

and illnesses. The OSHA 300 Logs, therefore,

provide a roadmap for an OSHA inspector

conducting an inspection. If, for example, several

injuries in the log are related to a particular piece

of machinery, the inspector will undoubtedly

scrutinize that piece of machinery for potential

hazards. In some cases, OSHA will use a pattern

of injuries as the basis for a willful citation, using

the log to show that the employer was on notice

that a hazard existed and did nothing to correct

the issue. Employers, therefore, should pay close

attention to the 300 Logs, particularly where

multiple employees experience similar injuries in

similar areas of a facility, as the logs can indicate

hazardous conditions.

Most employers are probably already famil-

iar with the illness and injury log, referred to

as the OSHA 300 Log. However, the decision

whether to record an injury or illness is often a

difficult exercise. This decision involves compli-

cated issues of medical causation, issues in com-

puting days away from work and confusion over

the definition of “medical treatment.”

In light of OSHA’s National Emphasis Program on recordkeep-

ing, and the proposed revisions to the injury notification regu-

lations, employers must be diligent in evaluating and properly

recording work-related injuries and illnesses. During a record-

keeping inspection, OSHA will request first aid logs and interview

employees to find out about injuries and illnesses that may not be

included on the employer’s OSHA 300 Log. Employers are advised

to consider the following statements to ensure compliance with

recordkeeping and notification requirements.

• Establishasystemthroughwhichemployeesarerequired

to report injuries or illnesses in the workplace. Inform

employees that they will not be subject to retaliation or

other negative action for reporting a work-related injury

or illness. Train supervisors to respond to employee reports

of injuries and illnesses. This will ensure employees receive

prompt medical attention. Injuries and illnesses should be

reported to the safety manager for evaluation of work-

relatedness and an accurate safety record of events.

• Ensurethatthepersonassignedtomaintaintherequired

OSHA records is trained to complete these forms accurately

and in accordance with OSHA requirements.

• Keepsupportingdocumentationofallinjuriesandillnesses

reported by employees. If the employer determines that

the injury or illness is not recordable, document the basis

for that determination.

• EnsurethatOSHAisnotifiedwithineighthoursofany

work-related fatality or the in-patient hospitalization of

three or more employees. If the business operates in a state

with its own occupational safety and health program, check

for varying notification requirements.

• EvaluateOSHA300Logstoidentifypotentialhazardous

conditions or practices that have led to employee injuries.

Document any corrective action taken to address such

conditions.

It is important for employers to not only provide a safe work-

ing environment for employees, but to react appropriately when

an injury or illness occurs. By accurately reporting and recording

these occurrences, the employer can increase awareness of safety

hazards with their employees to lower the risk of injuries and

accidents in the future.

tips to Avoid Common Pitfalls in Injury and Illness Recordkeeping

evaluate work-relatedness carefully. This can be a particular

challenge where an employee is suffering from a musculoskeletal disorder

or respiratory illness that developed over time. Where the cause of a

particular injury or illness is unclear, the employer must evaluate the

employee’s workplace activities to determine whether work activities were

a discernible cause of the injury or illness. Consultation with a physician is

permitted and encouraged for difficult cases.

don’t confuse the need for recrodkeeping with fault or blame. The OSHA recordkeeping requirements are designed to be no-fault. If an

employee is injured at work in a bizarre accident, or even because of the

employee’s own misconduct that violated the employer’s safety policies,

the injury may still be recordable if it meets the definition of “work-

related” and meets any of the other recording criteria.

Be aware of employees who travel or work from home. Do not

assume that just because an injury occurs “off site” that it is not recordable.

Employees who are injured while traveling for work or working from home

may still be recordable.

even pre-existing conditions may be recordable. If an event

or exposure in the workplace causes or contributes to the significant

aggravation of a pre-existing condition, the injury or illness may be

recordable.

don’t confuse workers’ comp with recordkeeping obligations. While there is some overlap in these two systems (for example, the

Workers’ Compensation insurer’s first report of injury or illness forms

can be used for OSHA recordkeeping purposes), a recordable injury for

OSHA purposes is not necessarily a compensable injury. OSHA has very

deliberately stated that recording an injury on the OSHA 300 Log is not a

concession by the employer that the injury is compensable, and vice versa.

29 C.F.R. §1904.0.

“light duty” may trigger the obligation to record. If the

employer keeps an employee from performing one or more of the routine

functions of his or her job as a result of a work-related injury or illness, the

injury or illness is probably recordable because it may constitute “restricted

duty” or “job transfer” under the meaning of the regulations. In some

cases, employers can give “light duty” to an injured employee to prevent

aggravation or additional injury without triggering the obligation to

record the injury or illness. This only applies if the employee is fully capable

of performing all of the routine functions of his or her job even with the

injury or illness.

Controlling Losses at the JobsiteBy Bob Elster

there are several issues for concrete

sawing and drilling contractors to

consider when controlling losses

at the jobsite. It is important for

contractors to be aware of these issues and

be well prepared for a project that requires

materials, tools and equipment to be stored at

the jobsite. By taking steps to properly secure

property at the jobsite, whether it be materi-

als, tools, equipment or vehicles, contractors

can guard against theft and damages that can

cost a company time, money and manpower.

joBSite protection For Building

materialS, toolS and equipment

Make sure to store materials in an area

where trucks can deliver or haul it away eas-

ily. Employees should also have easy access to

these materials so that forklifts can operate

safely. Theft of building materials and equip-

ment, especially in areas where large quanti-

ties of material are stored, is a serious concern

for many contractors. The installation of high

fencing, outdoor floodlights and some type of

alarm system is recommended. Signs displaying

“No Trespassing” should be posted around the

perimeter of the insured’s jobsite or on tem-

porary fencing. Lock boxes or locked storage

sheds can be helpful in preventing the theft

of tools and equipment from the premises. On

larger jobsites, hiring a guard service to patrol

the site during off hours is also advisable.

automoBile liaBility iSSueS

and tranSportation to and

From the joBSite

Concrete sawing and drilling contractors

have significant automobile liability because

they drive specialty vehicles and often assume

responsibility for transporting equipment and

materials to jobsites. Some contractors may

have specially-outfitted trucks with equipment

that has been permanently installed. In most

cases, materials suppliers will deliver products

directly to the work site. However, some larger

insured’s may have their own tractor-trailers

for hauling supplies to jobsites.

During the loading and unloading of vehi-

cles, damage may occur to third party premises

or bystanders may be injured if items being

loaded or unloaded are mishandled and fall

from the vehicle. To forestall controversy over

possible claims arising from such accidents, it

is desirable that the “Automobile Liability and

General Liability: Premises and Operations”

coverage be written in the same company for

the same limits. While some underwriters may

choose to cover physical damage to road-ready

cranes under an automobile physical damage

policy, usually the broadest protection for var-

ious types of mobile equipment is covered

under an Inland Marine form.

Contractors should foresee how many

vehicles will be on the jobsite during the bus-

iest phases of the project. They should also

determine the size and type of the vehicles. By

doing so, a contractor can achieve more effi-

cient parking, storage and access. How many

of the insured’s vehicles are owned and how

many are leased should also be recorded. If

a variety of vehicles, including general util-

ity trucks and vans, flatbed trucks, or tractor-

trailers, are to occupy one jobsite, consider

designating one employee to direct traffic and

coordinate parking. Loop traffic patterns and

jobsites that require turning around are to be

avoided if possible. Make sure to review any

rental agreements to determine the degree

of liability assumed under that contract.

Determine if there are any storage or over-

night parking requirements. Vehicles that offer

limited visibility to drivers when reversing or

maneuvering should be equipped with proper

warning devices, including lights and/or alarms

for reversing. Contractors should find out if

there are lanes specifically set out for work

vehicles, and if loading and unloading areas

have been established and clearly marked at

the jobsite. The insured’s work site supervisor

should coordinate with the general contrac-

tor to confirm predetermined roadways and

loading areas.

If personal vehicles are used for business

purposes, such as meeting with clients,

inspecting job sites or work-related travel,

a non-owned vehicle exposure will exist.

Contractors should set up a system to review

4 8 | septeMBer.11

i n s u r a n c e c o r n e r

an employee’s Motor Vehicle Record (MVR)

and verify that personal insurance coverage

is adequate. The employee’s frequency of

travel and radius of operations should also

be determined. Workers travel to jobsites daily

and may use company-owned vehicles to do

so. Estimators travel to potential clients’ work

sites when preparing bids for a job. Contractors

should identify the hazards associated with

typical travel routes their employees take.

Often, routes will be unfamiliar to drivers.

Other hazards can vary, depending on the

location of a jobsite—whether rural or urban,

for example. Drivers may face such hazards

as traffic congestion, poorly maintained

roads or inclement weather. Since most work

takes place during daylight hours and during

warmer weather, driving at night or under

winter road conditions can be rare. The best

way for a contractor to assess an employee’s

driving habits is to ride along as a passenger

a few times a year. Often, an employee will

take greater care of the company vehicle and

drive safer if they are aware their employer is

actively monitoring their driving habits.

If equipment and supplies are not properly

secured on trucks before being hauled to

jobsites, this could result in damage to other

vehicles and drivers. In terms of waste materials

from concrete cutting, loose debris on a truck

could fall and cause serious damage to other

vehicles or even bodily injuries to drivers or

passengers of those vehicles. Many states have

“tie-down” laws, which mandate the tying

down of loose materials that could be blown

or spilled onto roadways during transport.

Contractors should be aware of the laws

that apply to their state(s) of operation and

review information for other states via their

Public utility Commission websites. Even if the

hauling of waste materials is subcontracted to

another company, the cutting contractor can

sometimes still be held liable if a claim is made.

Experienced drivers and employees should

explain to new employees how to secure

materials or heavy equipment for transport.

It is essential that straps and chains of suf-

ficient strength are used to hold materials

securely in place during transport. The pres-

ence of secure strapping and chains should

be part of any vehicle maintenance check-

list the company uses. Experienced workers

should coordinate the loading of materials

or equipment onto vehicles. Loads must be

properly balanced in order to prevent the vehi-

cle turning over while in motion or jackknif-

ing. Employees should double-check that the

vehicle is properly flagged and accompanied

by an escort vehicle when hauling oversized

loads. The height of the load should be mea-

sured along with the clearance distances of

any overpasses or bridges the vehicle may have

to navigate through or under

during its journey. If a truck is

carrying a large load that can-

not navigate through certain

areas, pre-planning the route

can save time and fuel.

under some state laws, the

driver of a company vehicle or

even the employer can be held

liable for damages that occur

as a result of using cell phones

or two-way radios while driv-

ing. Contractors should consider

prohibiting the use of hand-

held cell phones while driving and encour-

age workers to pull over if they need to make

a call. Cell phone and radio safety rules can

be discussed with all designated drivers and

hands-free devices, such as headsets, can be

provided. Several states have issued bans on

the use of handheld cell phones while driving.

Contractors are advised to pre-program the

most frequently dialed numbers into company

phones or use phones that are voice-activated

to minimize driver distraction.

All truck drivers operating vehicles that can

carry more than 26,000 pounds or more must

hold a commercial driver’s license (CDL) issued

by the state in which they reside. Drivers who

have a Class A endorsement on their CDL may

haul oversized loads. Training should be devel-

oped for seasonal or temporary workers who

have less experience operating the insured’s

vehicles. Since the Fair Credit Reporting Act

requires written permission from the driver to

obtain their MVR, contractors are advised to

make the acquisition of this permission part

of the hiring process. Consider offering driver

safety training for all drivers.

The cause of certain accidents may be

attributed to vehicle malfunctions, such as

the failure of the vehicle’s tires or braking

system. Contractors should make sure that

vehicles purchased or leased have dashboards

equipped with warning gauges that let driv-

ers know if something is wrong with the vehi-

cle. Many companies have Best Practices that

require drivers involved in heavy trucking

operations to visually inspect vehicles every

day using a checklist. This checklist must be

completed by the driver before starting their

work shift.

It is important to make sure maintenance

schedules are in place for specialized vehicles.

All vehicles should be kept in good condition,

repaired promptly as required and inspected

regularly. Employees should not be permitted

to repair or assist in the repair of the insured’s

vehicles unless they are trained mechanics.

moBile equipment iSSueS

Concrete sawing and drilling contractors

will have significant inland marine exposure

due, primarily, to the fact that they will require

a mobile equipment floater policy for protect-

ing valuable equipment like cranes, forklifts

and front-end loaders. Smaller equipment can

be protected with a contractors’ equipment

floater policy. Valuable papers and records cov-

erage is recommended, and an outdoor sign

floater policy may also be required.

Contractors often have to move large

quantities of waste materials like concrete

debris and slurry. This requires the use of heavy

equipment like forklifts, front-end loaders and

cranes. Some contractors may also own hydrau-

lic jacks and/or mobile manlifts. Large or valu-

able pieces of heavy equipment should be pro-

tected with coverage equal to what it will take

to replace that equipment. Contractors should

make sure equipment schedules clearly state

the number, type and configuration of the

insured’s mobile equipment. While such items

are unlikely to be stolen due to their large size

and awkward handling, the physical appear-

ance of heavy equipment can make it an attrac-

tive target for vandals.

If mobile equipment is to be stored at a

jobsite overnight, the contractor should assess

the security measures available to minimize

the potential for vandalism. If such equipment

is stored in a garage or shed, doors should be

kept locked whenever the equipment is left

unattended. The jobsite should be surrounded

by sturdy fencing with “No Trespassing” signs

prominently displayed and be equipped with

outdoor floodlights. Depending on the total

value of the equipment at the jobsite, a con-

tractor may wish to hire a security guard to

patrol the area during off hours.

Portable, handheld tools and equipment

should be protected under an Equipment

Floater. Smaller pieces of equipment could be

stolen while employees are focused on per-

forming their assigned tasks. Over time, such

losses could accumulate and result in substantial

losses. There are several ways to monitor the

whereabouts of portable tools and equipment

at jobsites. upon completion of a job, employ-

ees should double-check the area for any items

they might have forgotten. Equipment inven-

tories should be created and regularly checked.

Contractors should evaluate how valuable tools

and equipment are secured when not in use

and make adjustments where necessary. Tools

can be stored in a lockbox or storage shed at

jobsites to improve security. A sign-in/sign-out

sheet can be created for employees when using

handheld tools or equipment. This sheet can

be monitored or countersigned by an assigned

site supervisor.

By following the advice and suggestions

given here, sawing and drilling contractors can

control and reduce losses at the jobsite and

improve their insurance mods. Some of the

suggested controls should not be difficult for

many contractors to implement, but can make

a big difference to a company’s bottom line.

The Concrete Sawing & Drilling Association is a nonprofit trade association of contractors, manufacturers, distributors and affiliates from the construction and renovation industry. Membership in CSDA is open to concrete cutting contractors, manufacturers and

distributors of concrete cutting equipment and affiliated companies who provide products and services to the concrete sawing and drilling industry. Founded in 1972, CSDA reached the milestone of 500 member companies in 2006.

WWW.CSDA.ORG CONCRETE OPENINGS | 6 5

CSDA has always been in my blood. My father, Mike, founded DeAndrea Coring and Sawing, Inc. in 1971 and was one of the original 18 contractors that met and formed CSDA the following year in 1972.

I first became involved in the business when I was 16, working weekends and holidays while I was in high school and college. I graduated with a degree in construction management and

then began working at the company full time. My dad had me work out in the field cutting concrete for seven years, an experience that helped me learn so much about the sawing and drilling industry, and about CSDA. In 1996, I took over the company after my father passed away. I spent a couple of years finding my feet and reorganizing the business, which was a challenge. It was during this time that I was contacted by Richard Long of Lombardo Diamond Core Drilling Co., who knew my father through CSDA. He explained how he had been through a similar situation to what I now found myself in, and invited me to visit his business to see how it was run. I spent time at Lombardo and came

away with invaluable knowledge that has benefitted me to this day. I was blown away that another contractor would open his doors to me and I saw one of the true benefits of being involved in CSDA—networking and the building of relationships throughout the industry.

Over the years, I have found other benefits of being a member of CSDA. My company uses the Toolbox Safety Tips and Best Practices issued by the association, and thanks to CSDA we have a comprehensive safety manual that has helped us win jobs. I have sent operators along to Operator Certification classes and each time they have returned with a new perspective on the work they do, demonstrating better cutting techniques and increased knowledge of the equipment they use. I have always felt that CSDA works hard to be proactive and self-regulate our industry while constantly changing to keep moving forward. I remind myself that in business you must change or die. I have always felt that CSDA holds true to this saying too, which is why my company has remained in the association for almost 40 years.

Celebrate CSDA’s 40th

Next March

concrete Sawing and Drilling Association (CSDA) members will

be heading to Maui next March to celebrate the 40th An-

niversary of the association. Maui has been the most popular

convention destination for members so it was natural to return to this

beautiful island for such a major milestone. It all started in 1972 when

Les Kuzmick, Sr. had a vision to form a cohesive group of contractors

and manufacturers. His goal in founding CSDA was to provide a forum

to promote the concrete cutting industry, share information and intro-

duce new sawing and drilling technologies. Forty years later, CSDA has

met those initial goals and done so much more.

While Les was instrumental in forming the association, there have

been many members who have served as Board members, Officers

and committee members that have taken Les’ original vision and

expanded upon it many times. Today, CSDA has nearly 500 contractors,

manufacturers, distributors and affiliated members. This is a testament

to the dedicated members who grew the association from 18 companies

that met at the Los Angeles Airport on May 19, 1972. CSDA has always

been mindful of its mission to promote the selection of professional

sawing and drilling contractors and their methods. Sawing and drilling

with diamond tools offers the construction industry many benefits

including lower total project costs, precision cutting, maintenance of

structural integrity, reduced downtime, reduced noise, dust and debris,

limited access cutting and the ability to cut heavily-reinforced concrete.

Times have changed over the past 40 years, and today’s sawing

and drilling contractors have had to chart a different path and develop

a different business plan to fit today’s technologically-advanced and

competitive environment. Today’s contractor utilizes advanced equipment

and technology to perform sawing and drilling in less time and with a

lower unit cost. This fact, among others, has allowed for tremendous

expansion in the sawing and drilling market. In addition, contractors

are also adding services, such as ground penetrating radar and selective

demolition, beyond the traditional services to grow revenue. The original

vision Les established has expanded in many ways.

The number of services, programs and member benefits available to

CSDA members has also grown. The list of resources and benefits is long

and includes safety manuals and videos, Toolbox Safety Tips, training

programs, an insurance program, promotional materials, online training,

a website, Concrete Openings magazine, a mentor program, field tools

like sample forms and worksheets, the slurry analysis, specifications,

member profile analysis, conventions, discount programs and free World

of Concrete registration.

Interestingly, however, the biggest benefit is missing from this list.

Arguably the key reason why many belong to CSDA is networking. Les

hoped that the personal relationships developed between members at

the annual conventions and meetings would foster the exchange of

information, and that has certainly happened.

Come join CSDA members March 4-9, 2012 in Hawaii to celebrate the

association’s 40th Anniversary. I look forward to welcoming members and

friends from around the globe to the beautiful island of Maui.

Comprised of a DM 280 motor and a DS 450 drill stand, the DMS 280 drill rig is full of features that enable the user to operate the machine safely and efficiently. It is perfect for a variety of applications, including openings for ventilation and plumbing as well as holes in corners for wall saw openings.

The motor is equipped with a LED indicator to show the load of the machine and to make it possible for the operator to drill at maximum pressure for best results. The two-speed carriage gearbox allows optimum feed pressure to be applied on different diameter bits which enables the bits to run at their maximum performance level. The motor and core bit travel smoothly on the column with minimal adjustment thanks to the V-groove roller carriage.

With all these features, the DMS 280 drill rig is one powerful machine.

Keeping you ahead of the game.

Teamwork.
