Whether you are looking to grow your business or trying to get back to pre-recession levels, recruit- ing the best people for your team is critically important to the success of your business. In order to find people that fit your culture and possess the appropriate skill set, you need to approach recruiting from a marketing perspective. After you’ve locked down an engaging job description, today’s great talent acqui- sition starts with creating the best ap- plicant flow and online job traffic pos- sible for your open position.

Technique 1: Examine your Job Distribution and your Referral Net- work Open Rates Screen your list of jobs and review the positions that are and are not per- forming. Copy the outreach strategies of those that are performing for those that are not. Also, make sure you have configured your applicant tracking sys- tem (ATS) to distribute your jobs to the top construction industry online sites. When thinking about your distribution process, ask yourself the following: • Are the jobs posted to your career page on your corporate website? • Are your jobs being distributed to the appropriate niche job boards for con- struction and skilled trades? Are they also being distributed to general job boards like Monster and Career Builder? • Have you distributed your jobs among your referral networks? Refer- ral networks can come from any- where—professional organizations, lo- cal organizations, universities and trade schools. • Do you have the capability in your ATS to make sure your networks are opening your emails? If so, check to make sure your referral networks are, in fact, opening your emails to them. If they are not, call and let them know your positions are available. • Work with your local and national targeted referral groups and support them with training, mentoring or job shadowing programs. Network to find additional contacts within that organi- zation. Technique 2: Review the Con- tent of your Job Ad To get the most attention for your ad, use construction-industry standard job titles such as equipment operator or laborer, instead of a title that is unique to your company. Try looking online to verify the title is common in the market. Ask yourself if construction job seek- ers will understand what you seek. Is what you are looking for clearly stated (i.e., not just a list of requirements)? This is a great time to review your content. Is the position terminology relevant? • Construction industry recruiting specialists suggest you use industry ter- minology for people to find you. Don’t get creative. Emphasize title or skill and location. Also include relevant job posi- tion keywords for search engine opti- mization. When you have nailed down the po- sition description of the job ad, craft your company story. Remember, it should sell your company and your differentiators. You want the best person, but those top performers don’t want to work for just any company. They want to work for the best. They might even be currently employed, so making yourself unique, interesting and engaging is important. The following components are es- sential to an effective construction in- dustry job ad: • Information/history about the com- pany • Introduction that describes your company culture • Details about the job • Minimum requirements • A “day in the life” description of what the position entails • Benefits – what makes yours the best company to work for? • Salary range or pay structure (hourly, base plus commission, overtime) • How to apply After you post the position, try it yourself and search for the job on the web.

Candidates need a place to go tovalidate their interest and find out more.

• Use LinkedInStart discussions through construction

industry specific groups like ConstructionJobs and Construction Professionals Fo-rum. Send out job alerts to your own net-work of contacts. Many of them are inthe same business that you are.

• Use FacebookTalk with your employees about shar-

ing your jobs through their personalFacebook page to friends and family.

Your existing candidate pool can alsobe a great channel to tap when lookingfor job applicants. If you have an ATS,search for past candidates and sendthem an email to re-apply for the newposition. Every day, past applicants gain

OSHA letter to Arizona

or I were to raise this question wewould need to follow the existing law,which states that we must obtain sig-natures from 10% of the population ofthe county to have the question put onthe ballet. I am only guessing here, butI would imagine these two tried run-ning this idea up the flagpole with lo-cal residents and got a less than a fa-vorable response. Hence the bill’ssponsorship.

So, how does this affect SACA?Given the down turn in the localeconomy, and with the population de-creasing at the fastest rate in the coun-try by percentage of population (as re-

President continued from page 1 ported by the Sierra Vista Herald onMarch 28) this move is not only unneces-sary but could lead to higher taxes by thecounty to support two additional supervi-sors. Increasing taxes hurts the local con-tractors. This, coupled with the contrac-tors that have been hit hard by thedownsizing of Fort Huachuca could nega-tively impact local business to the point ofputting them out of business.

Increasing the size of governmentgenerally leads to more regulations, some-thing the county has been able to hold downto date. Planning and Zoning codes andbuilding codes have been held at reason-able levels and look to remain that wayfor the foreseeable future. Increasing the

Board of Supervisors to five peoplecould lead to increased regulation inboth of these areas.

SACA enjoys a great relationshipwith the County on every level. Fromthe Community Development to Plan-ning and Zoning, along with the CountyAdministrator, we are able to work to-gether constructively. Adding two morepeople to the mix could change the di-rection we are moving to an antigrowthagenda. This would hamper efforts inthe future when it came time to de-velop areas around the county. It wouldbe a mistake to change the water man-agement plans in Sierra Vista sub wa-ter shed given it is critical to the mis-

sion of the Post; this equates to evenharder times for the number one em-ployer in the area.

All in all, the fact that we don’t have aneed, nor can we afford, to spend themoney to support two additional Supervi-sors, along with the uncertainty of whoand what it might bring to the CountyBoard of Supervisors, I would encour-age everyone to contact both SenatorGriffin and Representative Stevens andask the question, “WHY??” After theygive you the standard answer I receivefrom Senator Griffin, “It’s better for thecounty,” ask yourself if it is better for thecounty, or is it just better for the ones push-ing this agenda.

Ladders are a common sight in thefield of construction. They also con-tribute to frequent fatal accidents inthe ways of falling and electrocution.Types of materials used for laddersvary from wood, aluminum, and fiber-glass. Each material has a purpose.Wood is non-conductive, aluminum isanticorrosive, fiberglass is non-con-ductive and durable. No ladder shallbe painted or altered by the user. Eachladder has a duty rating label affixedto the side of the ladder when pur-chased. The duty label provides in-formation such a height and weightlimitations. The duty ratings for lad-ders range from household III (whichprovides a load up to 200lbs) to Spe-cial duty 1AA* (which provide a loadrating up to 375lbs).

Common types of ladders are usedin construction each has its own pur-pose. Step ladders are used to reachhigher elevations and should not beleaned against a surface. Extensionladders are used to be leaned on asurface and must extend 3’ higher thanthe next elevation landing surface.Extension ladders also have a rule ofthumb for the angle of set up, for ev-ery 4 feet in height the ladder is ex-tending, the base of the ladder mustbe 1 foot separated from the base ofthe wall or plane which the elevatedsurface is perpendicular to.

A few common rules for laddersafety

• Use a ladder when the break inelevation is 19 inches or more

• Do not use a metal ladder whenworking around electric equipment orelectric currents

• Place the ladder on a stable sur-face

• When leaning an extension ladder,place on a solid surface, never a win-dow or a movable object

• Secure the base of an extensionladder or have someone hold the baseto prevent movement

• Always face the ladder whileclimbing and descending

• Use the 3 points of contact rule.Always have either two hands and onefoot in contact with the ladder or havetwo feet and one hand in contact withthe ladder (unless using a platform lad-der)

• Never step on the top two rungsof a fixed ladder

Inspect the ladder you are using andmake sure the rungs are in good condi-tion. Make sure there is no broken hard-ware or pieces, and all locking mecha-nisms work properly. According toOSHA, in 2012 there were 775 con-struction deaths, 278 of the deaths werefrom falling. A SHORT DROP WITHA SUDDEN STOP MAY CAUSE SE-RIOUS INJURY UPTO AND IN-CLUDING A FATALITY.

WAM! April is Water Awareness MonthApril is Arizona’s 2014 Water

Awareness Month (WAM!) andthere is a lot to do this month cel-ebrating water locally and around thestate.

In Sierra Vista, the UA Coopera-tive Extension Water Wise Program,the City of Sierra Vista and theCochise Bicycle Advocates arekicking off the opening of the“WaterCycle Ride,” an easy 5-mileloop in the area around the Mall atSierra Vista that can be ridden on abicycle, walked or jogged. As a spe-cial during April’s WAM! celebra-tion, participants can even enter forprizes.

The loop utilizes a multi-use fit-ness path that follows Hwy 92,makes a detour through St.Andrews, connects onto BuffaloSoldier Trail, takes the connectingtrail through a natural area to AvenidaCochise and then returns back to theMall.

What makes the WaterCycleroute so much fun are interactiveeducational stops along the way.

Each stop explains a feature ofour watershed. Participants willlearn about the water cycle, rainwa-ter harvesting, how rain and snowreplenishes groundwater, why clean

water is important, how the city managesstormwater and why natural washes arebeneficial.

Participants can test their watersmarts by scanning a QR code on eachsite sign with their smart phone. As a spe-cial WAM! offering during the month ofApril, quiz participants can enter to wingreat prizes donated by The CochiseWater Project and M & M Cycling.

For activities happening around thestate and a calendar with a tip-a-dayideas, visit the WAM! website atwww.waterawarenessmonth.com.

Challenge yourself and your family toa WAM! goal such as saving a gallon ofwater a day by curbing wasteful habitssuch as not leaving water running, reduc-ing shower time by a minute or more andfixing that pesky leak (call a plumber!).Apply for a toilet and/or rainwater har-vesting rebate from thecochisewaterproject.com

Also take time to enjoy water. Cooloff at the San Pedro River, go find bea-ver dams, bring your fishing rod andcatch a few fish. Savor a good bookunder the green shade of a rustling cot-tonwood tree. Hike next to a stream inthe mountains, feel the velvet of dampmoss. Paint with watercolors!

Like the air we breathe, we oftenforget how important water is to life.Celebrate!

By Martin Holladay, GBA Advisoron greenbuildingadvisor.com

R-value measurements are subject toa fair amount of ridicule, especially bymarketers of radiant barriers. As it turnsout, however, the ridicule is mostly un-warranted.

R-value is a measure of a material’sresistance to heat transfer. Before 1945,resistance to heat flow was measuredby referring to a material’s U-factor. Thelower a material’s U-factor, the betterthe material is at resisting the flow ofheat. Because many people assume thathigh numbers on a scale are “better” thanlow numbers, insulation manufacturers

Understanding R-Valuefound it hard to market insulation by brag-ging about low U-factors. So the R-value,which is simply the inverse of U-factor,was proposed by Everett Shuman, the di-rector of Penn State’s Building ResearchInstitute. Since R = 1/U, the higher the R-value, the better the insulation.

Does it “only measure conduction”?Some manufacturers of radiant barri-

ers falsely claim that R-value measuresonly conductive heat flow while ignoringthe other two heat-flow mechanisms, con-vection and radiation. In fact, R-valuesinclude all three heat-transfer mechanisms.

The usual procedure for testing amaterial’s R-value is ASTMC518, Standard

Test Method for Steady-State ThermalTransmission Properties by Means of theHeat Flow Meter Apparatus. The testmethod requires a technician to measurethe thermal resistance of a specimen placedbetween a cold plate and a hot plate.

When a fiberglass batt is tested, heatflows from the hot side of the batt to thecold side. Wherever individual fibers ofinsulation touch each other, heat is trans-ferred from fiber to fiber by conduction.Where fibers are separated by air, the heatis transferred from a hot fiber to a coolerfiber by radiation and by conductionthrough the air. Finally, the effects of anyconvective loops within the insulation are

also captured by the test procedure.Since a material’s R-value is the mea-

surement of its resistance to all threeheat-flow mechanisms–conduction, ra-diation, and convection–it is a usefulway to compare insulation products.

Of course, an insulated wall is af-fected by many factors not addressedby R-value testing. Although the R-valuetest captures the effects, if any, of con-vective loops within the insulation, it ob-viously cannot be expected to measurethe amount of air leakage through a wallassembly once the insulation is installed.The rate of air leakage is affected by the

OSHA continued from page 7density of the insulation, the presence orabsence of an air barrier in the wall as-sembly, wind speed, and the stack effect.

Because of these factors, a leaky wallassembly insulated with fiberglass battswill usually perform worse than a wall as-sembly insulated with spray foam havingthe same R-value as the batts. The per-formance differences are due to sprayfoam’s ability to reduce air leakage, not toany difference in R-value between the twomaterials. It doesn’t make any sense toblame the R-value test for differences inair leakage between the two wall assem-blies.

To obtain the best performance fromfiberglass insulation, the Energy StarHomes program requires most fiberglass-insulated framing cavities to be enclosedby air barriers on all six sides. While therecommendation is sensible, it’s hard toachieve in the field. If such a six-sided airbarrier can be created, however, fiberglassinsulation will meet the performance ex-pectation promised on the product’s R-value label.

Some marketers of radiant barriers orspray foam insulation imply that R-valuemeasurements are meaningless. On thecontrary, R-value is a useful measurement.But just because you know a product’sR-value doesn’t mean you know every-thing necessary to predict heat flowthrough a wall or ceiling. R-value is justone factor among many to be consideredwhen deciding which insulation to use.Builders must also understand many othertopics, including air leakage and moisturemovement. No one has yet invented a“magic number” that replaces the require-ment for builders to study and understandbuilding science principles.

Does radiant heat pass through insula-

tion like radio waves?Another scare tactic employed by

some marketers of radiant barriers is theidea that conventional insulation materials— sometimes called “mass insulation” —allow radiant heat to pass right throughthem. Scam artists have been known towarn builders that “mass insulation is trans-parent to radiant heat.” The implication isthat a layer of aluminum foil is necessaryto prevent radiant heat from traveling likeradio waves right through a deep layer ofcellulose.

In fact, most mass insulation productsdo a good job of stopping radiant heat flow.Radiant heat easily travels through air (forexample, from a wood stove to nearbyskin) or a vacuum (for example, from thesun to the earth). But radiant energy can’ttravel through a solid material.

If the sun is shining on a concrete pa-tio, for example, the heat travels to the soilbelow by conduction, not radiation. Here’swhat happens: the concrete is first warmedby the sun (by radiation), and then thewarm concrete gives off some of its heatto the ground below (by conduction).There is no radiant heat transfer from thesun to the soil.

When radiant heat hits one side of adeep layer of insulation, only a tiny per-centage of that heat is “shine-through”radiation that manages to miss all of thefibers in the insulation blanket and emergeunscathed on the other side.

The fact that heat flows through a layerof insulation doesn’t mean that the insula-tion isn’t working. By definition, insula-tion slows down heat flow; it doesn’t stopit. Heat will always flow from hot to cold.The more insulation, however, the slowerthe rate of heat flow.
