University provideseconomics lesson inaward-winning LEEDconstructionBy Dermot MackPhotos: Sharp and Diamond LandscapeArchitecture
A multitude of green roofs and acommitment to energy savingshelped the University of Vancouver
Island, Cowichan campus, captureboth an international environmentalaward and local commercialbuilding honours.Built in Duncan, BC, the building
features six types of living roofsystems on three levels, accordingto Sharp and Diamond LandscapeArchitecture of West Vancouver.A lightweight green roof covers
88 percent of the campus, and over
30 percent is intensive green roofs,composed primarily of whitepumice, growing matter and sand.Level 3 is fully accessible andprovides quiet spaces to gather and

From the President
The holy trinityof roofingDecember 12 – seems like a fittingday to sit down and write my firstmessage as the newly electedpresident of the RCABC. Due to theblizzard in the BC Interior today Ielected to work on this message inthe cozy confines of my home.Like many contractors in our
proud association we have oursupervisory staff and crews workingfeverishly to bring jobs tocompletion prior to the Christmasholidays. This leads me into thecontext of my message. At this timeof year we share in the joyousapproach of the holidays and theusual frustrations of jobsites (poorweather, missing completiondeadlines and a general lack ofVitamin D within our biologicalmatter). I would like to focus onwhat I call the holy trinity ofroofing. This three sidedgeometrical design has become thefocus for all RCABC contractors. The congruent sides start as
equal parts of safety, quality, andproduction. I believe this is the mainobjective of all of our membercontractors. The focus on safetystarts with each and every memberand the pursuit of better safetyhabits. Our members are industryleaders in safety training and are allproud holders of the BCConstruction Alliance Certificate ofRecognition (COR). The RCABC is
the industry leader in training forthese safety programs, whichprovide more than individual safetytraining. They generate awarenessof safety for co-workers, the publicand the property that is involvedwithin the project. RCABCcontractors work with all levels ofregulatory bodies to ensure safework practices. Beyond roofingmany of our contractors employ orcontract out crane operators, truckdrivers, first aid personnel, trafficcontrol and hazardous wastespecialists.The next side of the triangle is
the quality side. This is the side thatseparates RCABC members fromother contractors. It is the un-compromising desire to provide thebest finished roofing project for ourcustomers. Building owners whochoose to have theirroof installed by anRCABC contractor andhave the installingcontractor supply aRoofStar guaranteeare doing their bestdue diligence for theirinvestment. They havethe added assurancethat comes with hiringa qualified contractor,with skilledtradespeople who aretrained in the technical applicationof accepted manufacturer’sproducts. RCABC-accepted thirdparty independent consulting andinspection firms provide qualitycontrol and ensure that the roof isinstalled to the required standards.
The inspectors also help RCABCmember contractors by makingrecommendations that provide asafer and more practical completionof the projects. Member contractors’employees are receptive to aninspector’s simple suggestions as toa safer work environment. Many ofthe inspectors were once
journeyman roofersthemselves and theirknowledge isinvaluable.Prayers for our
employees’ safety andfaith in our quality ofworkmanship lead meinto the final side ofthe triangle –production. Just thismorning our crewswent to job sitesthroughout BC. It
seems like on an hourly basis wecheck every type of weather-reporting means available. Yes,today was the dreaded 40%precipitation forecast. What to do,what to do? Let’s go for it! Theowners and general contractors just
want roofs on. The standard line weget in our industry is “well, it is notraining now!” By 9:00 a.m. theceiling in the sky became decidedlycloser to the earth and thesnowflakes came fast and furious.By the time the noon weatherreport hit the radio it sounded like aski report; “10cm base and 5cmfresh with another 5cm in theforecast”. Like all RCABC membersthe quality does not getcompromised. The crews stop thework they have in progress andtake all measures to protect thebuilding and the roof installation.This would discourage most peoplefrom carrying out their duties on adaily basis, however RCABCcontractors are a resilient breed.They will assure their customersthat God willing, they will havetheir crews back on site ASAP tocomplete the project in a timelyfashion. By selecting an RCABC member
an owner is choosing a roofingcontractor that is diligent andaccountable. Members haveresources that ensure completion of
the most challenging projects.Human, financial and equipmentresources play a huge role in alljobs big and small. I am alwaysamazed as I travel throughout BCand see buildings that have themost challenging roofs installed onthem. Most of the roofs have beeninstalled by RCABC contractors, andhave RoofStar guarantees. Thesebuildings are true landmarks withinour province and were constructedwithin demanding schedules. I feel very privileged to be the
president of such a longstandingand respected association. Our firm,Western Roofing, based out ofKamloops, is one of the originalfounding members of RCABC datingback to 1962. Whether you are alongstanding member or one of ournewer contractors you are part of alikeminded group of leaders in theroofing industry when it comes tosafety, quality and production.During this year I would love to
field comments and questions fromanyone reading Roofing BCmagazine. If I do not have theanswer I will do my best to pointyou in the proper direction. With thelaunch of our own RCABC andRoofStar marketing initiatives wehave staff in place at our Langleyoffice to fulfill all of your roofrelated requests.Please feel free to contact me via

50,000 square feet and cost $12per square foot, for a total of$600,000. The membrane beneath the
green roof is from Soprema Canadaand described as a “protectedmembrane roof/inverted roofmembrane assembly.”The irrigation is a Rainbird
system with a weather-basedcontroller that collects rainwater incisterns and pumps it up to the roof.A “blue roof” provides additional
stormwater retention and treatmenton the green roof. It is similar to arain garden, and offers additionalwildlife habitat and plant diversity.Universal Sheet Metal Ltd. of
Saanichton, BC was the roofing
contractor and the project carries afive-year RCABC RoofStar warranty.The project has been awarded
LEED Gold certification throughsustainable site, water efficiency,natural ventilation and daylighting,and high performance buildinginitiatives.The campus received a 2013
Green Roof and Wall Award ofExcellence for the University ofVancouver Island. This is one of theawards given by Green Roofs forHealthy Cities, which recognizesinnovative living architecture inNorth America.The project also captured a
Commercial Building Award fromthe Vancouver Island Real EstateBoard; and the Roy WillwerthPrecast Concrete ArchitecturalRecognition Award from theCanadian Precast/PrestressedConcrete Institute was presented toVictoria-based Garyali Architect Inc.for their design of the campus. ■

ASTM International is currentlydeveloping several standards forsustainable roofing systems.ASTM Committee D08 on
Roofing and Waterproofing’ssubcommittee D08.24 onSustainability, is working onnumerous standards, including
ASTM WK26599, Guide for Designof Sustainable, Low-slope RoofingSystems, which will address theprocess designers use to determinethe demands and factors a roofingsystem must be able to withstand.These factors include weather, foottraffic, building pressurization, and
interior humidification.“This standard will help
designers and specifiers design adurable, long-lasting roof capableof protecting the building structureand contents,” consulting engineerand ASTM D08.24 task group chairEric K. Olson, PE, explained toConstruction Canada Online. “The standard places emphasis
on analyzing all the adverseconditions the roof will need toendure to help select a durablesystem. Roofs are unique buildingsystems in that failure places thebuilding and its contents at risk ofdamage,” said Olson.The standard will address the
gap between roofs being designed
to be durable without incorporatingsustainable properties. In otherwords, it provides the guidelinesfor a durable and sustainableroofing system.“Replacing a failed roof and
damaged building contents andstructure creates an environmentalburden,” said Olson. “Currentsustainability trends such as use ofroofs for open/paved space,vegetation, photovoltaics, andrainwater retention, make life evenharder for the roof and furtherincrease risk of roof failure if the
roof is not properly designed.”Additional standards in
development include:• ASTM WK26595, Guide for RoofSystem Durability;
• ASTM WK26596, Practice for(Product Category Rule) forPreparing EnvironmentalProduct Declarations of Low-slope Roofing Membranes; and
• ASTM WK29304, Guide forSelection of Roofing/Waterproofing MembraneSystems for Vegetative (Green)Roof Systems. ■

Don’t getthe winner’scurseNever break the threecardinal rules ofestimatingBy Tara Landes
Minimizing costs is everycontractor’s goal during thetendering process. Too often,contractors focus solely on price,adopting strategies and pricing thatcan kill the rewards of winning thecontract. These tactics can threatenthe company’s overall financialhealth. Break these three cardinalrules for minimizing costs, and yourisk losing any profit you mighthave earned for the job.Rule 1: Never adjust theestimate to compete on priceLet’s define a couple of terms:A “bid” or “price” is the dollar
value the customer is willing to payto buy your service. It’s largelydetermined by what the market willbear.The “estimate” is an internal
calculation composed of three parts:the dollar value of materials +labour + overhead.The estimate, therefore, should
be as accurate as possible andcannot be adjusted for marketconditions – your costs don’tchange. You can make a strategicdecision to decrease the profit on ajob, but you can’t decrease the
estimate. Price – estimate = profit.If you’ve ever heard these
comments, you’re probably breakingthe first rule of estimating:• To the estimator: “We really needto sharpen our pencil on thisone.”
• To the project manager: “Put in afudge factor just in case it’s off.”
• To the sales rep: “We need tochange the estimate for strategicreasons.”
Rule 2: Never makeassumptions whencommunicating with the fieldThe estimator carefully considers
how the job will be constructed,including the materials, the labour,maybe even the specific staffinvolved. They use formulas andestimating templates and also usetheir years of experience to makethe best judgments of how best tocomplete the job.The thing about experience,
however, is that no two people haveexperienced life exactly the same
way. It is unlikely(impossible?) thatone person’s gutfeel about how torun the job will bethe same as another person’s. If theestimator is not explicit about theirreasoning, it is unlikely that theproject manager will meet theirexpectations. Best practices forcommunicating with the fieldinclude holding kick-off meetings,developing project plans, andestablishing feedback loops whilethe job is in progress.Rule 3: Never skip the final jobcostingOnce the job is complete, the
final job costing should be detailedenough to determine how accuratethe estimate was. It is statisticallyimpossible for estimating to betotally accurate all of the time. Anestimate is simply a best guess ofwhat will happen in the future, andunless you have a time machine, it’spretty hard to predict perfectly. The
final job costinghelps determinethe degree ofaccuracy of yourestimates and
identify patterns that allow you totighten the process for next time.There are three types of errors:
1. Quantity errors: These typicallyinclude inaccurate estimates ofthe number of hours or amountof material required for a givenjob.
2. Rate errors: Most often, thesestem from inaccurateunderstanding of a company’scost structure. If a company doesnot have an annual budgetingprocess, rate errors are almostguaranteed to be a significantproblem in the estimatingprocess.
3. Errors of omission: These mostcommonly happen when wellintentioned, loosely supervisedstaff perform work outside ofscope without proper
documentation, and do notcharge the client.
Have you got the winner’scurse?Contracting can be a bitterly
competitive line of work. In leantimes, it feels like your competitorsare “giving it away” in order to keeptheir guys on the tools. Inprosperous times, it feels like it’swho you know, more than what youknow, that wins the best jobs.In reality, successful companies
rarely “buy work” with pricingdiscounts. Instead, they have theprocesses and systems in place toensure they never break the threecardinal rules of estimating. That’sthe winner’s curse; whoever makesthe biggest estimating mistake winsthe job. ■

Housing starts trackdown from 2012Victoria – BC housing starts slowed in October following a Septemberbump in activity, reports Statistics Canada. Starts in BC’s urban marketspulled back to a seasonally adjusted pace of 23,900 units, marking a 19percent drop from September as fewer multi-family projects got underway.October’s drop suggests a softening in construction activity – a trend
also evident in September building permits.Following an August uptick, residential permit volume retreated in
September. Total volume fell to a seasonally adjusted $513.1 million duringthe month, down 14 percent from August on lower volume in both thesingle and multi-family sector. Through three quarters, residential buildingintentions were about 3 percent lower than in the same period in 2012. Adecline in permits to the weaker levels of late 2012 points to a slowdownin new home and renovation construction in the fourth quarter.A slowdown would be consistent with an expected moderation in the
resale market and elevated levels of new home inventory in markets acrossthe province. Full-year starts are forecast to end 2013 at 25,800 units,down 6 percent from 2012 before advancing 4 percent in 2014. ■

As of January 1, 2014, changes toR-values for polyisocyanurateinsulation go into effect inaccordance with the newly updatedASTM C1289-11 standard forinsulation testing. The new industry-wide standard
used in determining long-termthermal performance for polyisoroofing products brings new testingmethods for the determination andcalculation of Long Term ThermalResistance (LTTR) values.“The products’ physical
properties won’t change. Only theway LTTR values are calculated willbe adjusted,” explained MikeDuchame of Carlisle SynTec, aleading supplier of polyisoinsulation.In the new year, the LTTR values
will change according to ASTMC1289-11. As projects are bid forinstallation in 2014, roofingcontractors should verify thespecified LTTR values and ensurethat quotes reflect the appropriatethickness for the new LTTR values.
This change is being made inorder to provide a comprehensiveapproach resulting in increasedreliability and consistency in theprediction of long-term thermalperformance of North America’smost popular rigid roof insulation,according to a Firestone bulletin.ASTM C1289-13e1 now
incorporates two test methods,ASTM C1303-11 and CAN/ULC-S770-09, which offer a similarapproach to predicting the longterm thermal performance for foaminsulation materials that exhibit airand blowing agent diffusion oraging over time.Both test methods employ a
technique called “slicing andscaling” to accelerate this agingprocess and provide an accurate andconsistent prediction of product R-value after five years, which isequivalent to a time-weightedthermal design R-value for 15 years.Based on extensive research overthe past five years, including bias
and ruggedness testing, mostthermal insulation researchers nowagree that the results of both ASTMC1303 and CAN/ULC–S770 providesimilar and consistent resultspredictive of actual ageperformance.As roofing projects are bid for
installation in 2014, the specifiedLTTR values must reflect theappropriate thickness for the newLTTR values (see chart on right). ■

The National Research Council ofCanada (NRC), in collaboration with Special Interest Group forDynamic Evaluation of RoofingSystems (SIGDERS), has beeninvestigating low slope roofassemblies for wind upliftperformance. In recent years,commercial roofs are being used(abused) as a platform with severaladd-ons. These add-ons can includepavers and solar panels, forexample.In this report, the focus is on the
most popular roof add-on: concretepavers. (In our Roofing BC summerissue we discussed the NRC studylooking at wind resistance of solarpanel setups.) The complete study,released in 2013 at the 28th annualRCI convention and trade show,was authored by NRC’s Dr. B.A.(Bas) Baskaran, Dr. SudhakarMolleti and engineer Steven KeePing Ko.
Concrete ideasApplying the Canadian
Standards Association (CSAA123.21-10) dynamic test protocol,the study looked at concrete paversas add-ons over a modifiedbitumen membrane.“Wind uplift forces acting on a
roof system can cause severe roofdamage. Irrespective of the roofingsystem, the wind dynamicsintroduce stresses within theroofing system causing fatigue,which may result in catastrophicfailure over time. Depending on themagnitude and frequency of thewind events, this could lead tocostly insurance losses,” Dr.Baskaran writes. “For this reason, wind uplift
testing of roofing systems hasbecome a critical designconsideration for insuranceapproval agencies, architects,engineers, roofing contractors andmanufacturers.”Two separate systems were used
to wind test concrete pavers on aroof.• System 1 consisted of a steeldeck, plywood, support board,modified bitumen membrane(cap and base sheets), Fabrenefabric, two layers of polystyreneinsulation and concrete paverswith plastic H-clips (see photos).
• System 2 consisted of poured-inconcrete composite deck,modified bitumen membrane(cap and base sheets), Fabrenefabric, two layers of polystyreneinsulation and concrete paverswith H-clips.
Failed at 125 psfThe first system failed at a wind
suction pressure of 125 psf (poundsper square foot) [6.0 kPa(kilopascals)]. During the failureinvestigation it was noticed that theweakest link in the system was thesupport board attachment to thestructural deck (steel deck). Themetal plates and fasteners pulledthrough the support board, causingthe delamination of the membrane.This delamination resulted indiscontinuity in the load transferpath thus allowing air intrusion intothe system. The lifted membranewas subjected to a pressuredifference of 125 psf (6.0 kPa).“The H clips maintained the
interconnection of the pavers [but]
the whole paver setup was upliftedduring wind gusts,” the researchersnoted, adding “It should be notedthat in cases where the failure ofthe roofing components led to theuplift of the pavers, the liftedpavers settled back to their originalposition without any damage tothemselves or to the clips.”Poured in placeThe second system, with a
poured-in monolithic concrete deck,performed exceptionally well inresisting the extremely high windpressures greater than 270 psf(12.9 kPa). With an air-sealedconcrete deck, the air intrusion intothe system was completely negated,and therefore the suction pressureswere transferred equally across allthe surfaces of roofing components(no pressure gradient) without anyuplift forces acting on them.“The applied uplift force is
resisted by concrete deck and itsattachment to the joist, which inthis case was the strongest link,thus allowing the system to sustainhigh uplift pressures,” theresearchers noted.Conversely, if any air intrusion
into the system occurs, it can breakthe load transfer path within thesystem components, and theirresponse might induce significantuplift movements of the pavers.
This has been evident in System 1,which demonstrated the necessityfor air tightness in the system atthe deck level.When testing a roofing system
for dynamic wind upliftperformance, many componentdetails and constructionmethodologies are considered.Some considerations for componentdetails include the deck type, deckattachment, insulation compressivestrength, membrane tensilestrength, and air permeability(leakage) of the individualcomponents and the roof systemcollectively. For this reason thereported wind uplift ratings fromthis study only applies to systemsbuilt at the NRC in the mannerdescribed in this report.Takeaway: Preventing airintrusion into the assembly is akey factor for concrete pavers tobe durable against wind uplift. ■

Three-quarter-inch 4’ x 8’ (19 mm x 1219 mm x 2238 mm) sheets ofplywood were placed on top of the steel deck. Sheets were attached with 8fasteners per board to the steel deck using #14 – 2 ¾” (70 mm) fasteners.
Cap sheets were torched to thebase sheet layer of the modifiedbitumen membrane system.
Concrete pavers were interconnectedwith plastic H clips of 5” x 3 ¼” x 2 ½”(127 mm x 83 mm x 64 mm).

Raleigh, NC – Coldweather calls for specialhandling and applicationof styrene butadienestyrene (SBS) modifiedbitumen, cautions SBSexpert Kirk Goodrum inthe latest issue of theRCI’s Interface journal.The research and
technical developmentmanager at Siplast notesthat “installation andstorage techniques”should change when thetemperature falls below10 degrees Celsius (50degrees Fahrenheit).The following are some tips for
installing SBS in colder weather:• Adhesives and roll goods shouldbe stored in a warm place.
• In cold weather, torch-gradesystems are the most forgivingand offer the best results.
• If the system will be appliedusing hot asphalt or cold process,cut the sheets in halves or thirds
to facilitate uniform adhesion.Allow the cut sheets to lie flatoutside for 15 minutes to allowthe membranes “to acclimate andrelax.”
• When using heated asphalt as anadhesive, do not overheat theasphalt as this can damage theasphalt, change its physicalproperties and is a firerisk.
Type 3 and Type 4 are themost commonly usedasphalts for application ofSBS modified bitumenmembranes. Such asphaltshould be at a minimum of204 degrees Celsius (400˚F)when it makes contact withthe membrane.• Apply (mop) the heatedasphalt no more than fourfeet ahead of the roll.
• Be aware of the
“equiviscoustemperature” (EVT),which is the temperatureat which asphalt has theviscosity similar to oliveoil. Notes Goodrum, “Theviscosity of moppingasphalt increases at anexponential rate: it cango from the consistencyof olive oil to molasses inminutes or seconds,depending on theweather conditions.”• When using coldadhesives, follow themanufacturer’s
recommendations for coldweather applications. Wheninstalling the membrane, applyconsistent pressure to ensureuniform contact between themembrane and the adhesive,because the membranes will bestiffer in cold weather. ■

Delta – The Boundary Bay IndustrialPark is set to become greaterVancouver’s largest new industrialdevelopment – and the largestroofing project in the region – whenPhase I completes in 2014.The 47-acre project, by real
estate development companyDayhu, will boast warehouse spacesupwards of 900,000 square feet.“We’re effectively the only option
under construction that can offercontiguous space of this magnitude,”says Paul Tilbury, COO of TheDayhu Group.According to CBRE’s Chris
MacCauley, there isn’t a singleoption right now in Vancouver forcompanies in need of warehouse
space in the 300,000 to 400,000square foot range.Delta has become the new
industrial destination. Triovest isbuilding the South Fraser IndustrialCentre, with 277,000 square feet injust two buildings, while Grosvenoris completing a 160,000-square-footproject. Also, Beedie DevelopmentGroup is finishing its smaller,120,000-square-foot Tilbury WestCorporate Centre this year.Hindered by a lack of land, Metro
Vancouver has historically been lesscompetitive in attracting big userscompared with Calgary, Toronto andthe US. But with the expansion ofPort Metro Vancouver and thecontinued growth trade, theshortage of industrial space has
spurred a rush of speculativeconstruction.Victoria, by comparison, is seeing
near zero industrial development,despite an increase in retail, officeand multi-family projects.Colliers International reports that
Victoria has seen more industrialspace given back to the market thanleased up for the first time in atleast 15 years. This is known asnegative absorption. At 4.5 percentthe industrial vacancy rate hastouched at least a 10-year high,new construction has fallen nearly50 percent in the past year to78,000 square feet and 33,400square feet was pushed back ontothe market during the first ninemonths of last year. ■

BCREA sees commercialstrengtheningVancouver – The BC Real Estate Association is forecasting strongercommercial construction for 2014, based on its “commercial leadingindicator.” The indicator is running 0.8 percent above the same period in2012, at 114.1 BCREA economist Brendon Ogmundsen said the indicator,which tracks retail sales and office employment, points to “an improvingeconomy and stronger commercial real estate action in 2014.”The recovery would be welcomed. While total non-residential
construction permits in BC increased in September from August, the outlookfor the year is not positive, according to Statistics Canada.In September 2013, municipalities issued permits valued at $326.5
million, marking a monthly gain of 10 percent. Stronger public-sectoractivity offset a decline in the industrial space. Volume has generallyclimbed since the end of 2012.Despite this positive trajectory, year-to-date activity was still down 25
percent from the first three quarters of 2012, reflecting fewer major projectstarts. Annual non-resident permit volume in 2013 is forecast to settle at 20percent below 2012’s levels, but remain above levels seen between 2009and 2011. ■

Walkpads, hatch safetygates and tape allrecruited to protect anddirect roof trafficBy Dermot Mack
Commercial roofs today are moreaccessible to more people than everbefore. Higher maintenance accessrequired for green roofs, HVAC andother mechanical systems, the useof roofs for solar platforms,
skylights and communicationequipment – and for amenityspaces – mean that the integrity ofthe membrane and safety concernshave become much morepronounced.“It is especially important to take
safety measures when dealing withspecific areas of the roof, such asaccess points (ladders, hatches, anddoorways) and around mechanicalequipment requiring maintenance,”
notes JimTierney, BuildingOwner ServicesManager withFirestoneBuildingProducts. “Extrasafetyprecautions arealso necessaryin the wintermonths orfollowing astorm sinceroofs can beslick after rain,frost, orsnowfall.”A recent trend
is the use ofsafety guardsaround roof hatches and “ladderup” safety posts on roof hatchladders. Roof hatch safety shouldbe taken very seriously, and guardsand posts can help to minimize therisk of falls.The Canadian
Roofing ContractorsAssociation notes in asafety bulletin thatroof access shouldideally be throughinterior staircases,and the roof hatchaccess should be well away fromroof edges and be equipped withguardrails. On buildings whereinterior access is unavailable,permanent ladder tie-off anchorsshould be strategically placed forsafety.A good first – and affordable –
step is to use brightly colouredsafety tape and markings aroundroof perimeters and hazards. Theseproducts serve to create a safetyzone around the roof edge,mechanical equipment, and otherhazards by visually drawingattention to these areas.
Walkway padsWalkway pads can be another
essential item that helpsincrease safety levels. Walkwaypads serve two purposes. First,they provide a non-slip surface
for thoseaccessing theroof. Second,the padsactuallyprotect thesurface fromwear and
tear associated withindividuals accessing theroof for maintenanceand repairs. Walkwaypads safeguardpeople and roofsystems yearround, butthese arealsoidealforthe wintermonths as they can bemanufactured to display coldflexibility.
NotesTierney,“Rooftopaccess shouldbe restrictedto trainedprofessionalswho aremindful oftheirsurroundings.Safetyprotocols andproducts arebeing drivenby [safety] aswell as risinginsurancecosts.”He adds that
building ownersoftenpurchasepreventivemaintenanceprogramsfromcommercialbuildingmanufacturersin order tomaximize thelife of theirroofs and followwarranty
guidelines. “Thereis a trend of movingaway from purchasingthe standard 10 yearwarranty and investing in15 year or even 20 yearwarranties,” Tierney says.The CRCA agrees, noting
that high-quality productsinstalled by pros will requireless maintenance and repairs –and fewer people on the roof. ■

Victoria’ssecretA building boom isunderway in the city afterfive years of slowconstructionBy Dermot Mack
After snoozing for most of the pastfive years, Victoria has seen itsconstruction pace accelerate headinginto 2014. In 2013, total buildingpermits were running 10 percentahead of 2012 as of mid-year at anaverage of $52 million per month,but this year could easily surpassthat pace.Metro Victoria is the home of
Canada’s Pacific Navy, a strongpublic sector employment base andthriving tourism, which keeps theunemployment rate among thelowest in Canada. Yet the realgrowth is being shaped by aknowledge economy characterizedby high technology, advancedengineering, clean energy and twotop-ranked post-secondaryinstitutions with the University ofVictoria recently beingnamed Canada’s No. 1Comprehensive University. “The Metro Victoria
region is really positioningas a tier-two creative andentrepreneurial centre inNorth America, verysimilar to a Boulder,Colorado or Austin, Texas,”says Dallas Gislason,economic developmentofficer for the GreaterVictoria DevelopmentAgency. “We’ve beenranked as the second mostcreative city in Canada byDr. Richard Florida [author
of The Rise of the Creative Class].”Even as multi-billion dollar
shipbuilding contracts fire up, a newwave of high-rise housing ascendsand the airport expands to meetinternational demand, Gislason sayslifestyle will remain Victoria’seconomic trump card.A $3.3 billion federal
shipbuilding contract alone willprovide decades of employment atEsquimalt’s Victoria Shipyardswhere finishing and maintenancework will be done on non-combatvessels and smaller ships.Such investments have further
spurred $1.2 billion in residentialand commercial developments.The construction projects include
the $100 million mixed-use EagleCreek by Vancouver-based Omicronon a 10-acre site across fromVictoria General Hospital. Nowunderway, it will include 190,000square feet of retail and offices and160 homes. Meanwhile, everymajor shopping mall in GreaterVancouver is being renovated orexpanded.New condominium and rental
apartment construction in Victoriawas running at more than 100 units
per month in 2013, with much ofthe action downtown where half adozen high-rises are underconstruction. One is a major proposal from
Jawl Properties for an entire block,anchored by the former Royal Bank
building on DouglasStreet across from CityHall, which Jawl plans asa mixed-use residentialand commercial project.Another is an entire
block in the James Bayarea that was sold in2013 by the provincialgovernment. ColliersInternational ismarketing an office andretail complex calledCapital Park for the site,and the province haspledged to lease180,000 square feet of it. There will also be
retrofit work for sheet metal androofing contractors. The old CrystalPalace is being eyed for a $58million replacement or at least a $6million makeover. Victoria’s FireStation No. 1 will be upgraded tothe tune of up to $18 million.Other major projects underway in
the capital region include a $9million upgrade to Ecole QuadraElementary School; $180 million tomodern the maintenance facilities atCanadian Forces Base Esquimalt;and a new $104.8 million helicopterbase and buildings at VictoriaInternational Airport. ■

LEGAL AFFAIRS
Courtsfrown on‘if-paid’ and‘when-paid’clauses“Courts have beenhesitant to penalizesubcontractors byenforcing this type ofclause”by Chris Hirst
Those in the construction industrywill have heard of the “pay-when-paid” clause and its evil twin, the“pay if paid” clause.Though widelyused, these clausesremaincontroversial andare often confused.While both of
these terms attempt to affect ageneral contractor’s obligations tosubcontractors when the ownerdoes not pay that generalcontractor, they differ in importantways.A “pay-when-paid” clause (i.e.,
that the general contractor will paythe subcontractor within “X” days ofreceiving payment from the owner)really only addresses the timing ofpayments; it does not affect theunderlying obligation to pay forwork performed.On the other hand, a “pay-if-
paid” clause (i.e. that the generalcontractor only incurs an obligationto pay the subcontractor if, and onlyif, it is first paid by the owner) mayconstitute a condition precedent thatexcuses the general contractor fromhaving to pay the subcontractor ifthe owner does not pay the generalcontractor.The issue with a true pay-if-paid
clause is that it attempts to create acondition precedent, that is, a clauseupon which the entire trade contractdepends. But, unlike other
conditionsprecedentthat generallydepend on theconduct of the subcontractor, pay-if-paid clauses are activated by a non-paying owner, a situationsubcontractors have no control over.For this reason, courts have beenhesitant to penalize subcontractors
by enforcing thistype of clause.RulingTake the Nova
Scotia Court ofAppeal case,Arnoldin
Construction & Forms Ltd. versusAlta Surety Co. (1995), where theowner failed to pay the generalcontractor. The surety in turnrefused to pay the subcontractorunder the labour and materialspayment bond. Surprisingly enough,the subcontractor was dissatisfiedand sued.At issue was a clause in the trade
contract that stated the finalpayment to the subcontractor wouldbe made within 30 days of thegeneral contractor being paid. Thesurety claimed the clause was acondition precedent, pay-if-paidclause.The subcontractor argued the
clause was not a conditionprecedent but a pay-when-paidclause that only affected whenpayment was to be made, notwhether payment would be made.The subcontractor lost at trial andappealed.The Nova Scotia Court of Appeal
agreed with the subcontractor,stating the clause “did not negatethe [prime] contractor’s obligation to
payfor the
work.” Thecourt looked
at the clause inthe context of the
whole contract andthe obligations it
imposed on the generalcontractor. In this light, the
clause only outlined whenpayment was to be made, and didnot constitute a condition precedent.The Court of Appeal reversed thetrial decision and awarded thesubcontractor the balance owing onthe completed contract, $547,857.27.The Court of Appeal also noted
that pay-if-paid clauses requiremuch clearer language than thatused in this clause, stating that “anintention so important cannot beburied in obscure language thatwould not alert the subcontractorthat payment for the subcontractwork was conditional on the ownerpaying the [prime] contractor.”Court’s “disdain”Another example of the court’s
disdain for these clauses is a recentdecision out of Ontario where apay-when-paid clause wasexamined in the context of Ontario’slien legislation.In Bradhill Masonry Inc. v.
Simcoe County District SchoolBoard, it was argued that the pay-when-paid clause eliminated thesubcontractor’s entitlement to abuilder’s lien.The owner argued that since the
subcontract provided that thesubcontractor would only be paidonce the general contractor hadbeen paid and since the generalcontractor had not been paid at thetime the lien was filed, thesubcontractor had no right to lien.The court had little time for this
argument and found that theowner’s argument amounted to littlemore than a shell game that wascontrary to the purposes of the LienAct.
It based its decision on twogrounds. First, the court found thatthe contract, like all buildingcontracts, was subject to the OntarioLien Act, not the reverse.Accordingly, this contractualpayment provision could not affectthe rights of the subcontractorunder the Lien Act.Second, the court found that the
fundamental nature of the lien right,based as it is on the price of thematerial or services and the supplyof those materials and services tothe improvement, could not beaffected by the status of theaccounts as between the generalcontractor and the subcontractor.
Despite impediments to theenforcement of these clauses in thecourts, it is unlikely that pay-when-paid or pay-if-paid clauses willdisappear from construction contractvocabulary anytime soon.Subcontractors can, however,
take some comfort in the fact thatan unpaid subcontractor’s rights tolien a project for its unpaid accountsare not likely to be significantlyimpaired by such clauses. ■
