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.
concrete openings | 7www.csDA.org
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
c o n c r e t e c a s e s
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
Ground penetrating radar was used to scan concrete structures for hazards.

c o n c r e t e c a s e s
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.
c o n c r e t e c a s e s
concrete openings | 1 5www.csDA.org
c o n c r e t e c a s e s
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.

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.
concrete openings | 1 9www.csDA.org
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.
c o n c r e t e c a s e s
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.

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,

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
Safety and CSDA-OBP-1006—Ladder Safety, include precautions and
guidelines for the safe use of scaffold and ladders in the sawing and
drilling industry.
To date, the Alliance has released six Best Practices and a Toolbox Safety
Talk. Subjects include Highway Work Zone Safety, Reducing Silica Exposure,
Defensive Driving, Electrical Safety and Sprains and Strains Prevention. Four
of the Best Practice documents are also available in Spanish.

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

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

c o n c r e t e c a s e s
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

In addition to reporting fatalities and catas-

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.”

concluSion
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.

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.
