Failure data clearly supported that the majority of the roof failures were due to the failure of metal roof edges. These

findings suggest that current building codes in North America (i.e. NBCC and ASCE) do not accurately identify wind design loads acting on roof edge metal systems. The Roof Edge Systems and Technologies (REST) project is a consortium of academia, government and roof industries

Three edge configurations – the Anchor Clip Configuration (ACC), Continuous Cleat Configuration (CCC) and Discontinuous Cleat Configuration (DCC)– were installed on the building’s penthouse roof to study the measured wind-induced pressures acting on the surfaces. The Canada Post Pacific Processing Centre was identified as a suitable field monitoring site for this study. Positioned at an airport location, the building can be categorized as having an open terrain exposure with the predominant wind direction ranging from south-west to north-west. In order to be exposed to the critical wind direction range, instrumentation was placed on Penthouse 6, located on the west

side of the building with a parapet facing the incoming west wind. Building owner Michael Bryson said “Canada Post has been involved with the NRC for the past 20 years, including participation in a major study to understand roof membrane properties in the late nineties. When the NRC was in search of a new building site, the Canada Post Pacific Processing Centre in Vancouver was an ideal choice for wind performance. For building owners like me, this provides a comfort zone to know that the measured wind uplift forces are less than the designed values”. All installation and roofing work was completed by RCABC member Marine Roofing, with material provided by Carlisle SynTec

Systems. Larry Lemke of Marine Roofing said “We have installed several million square feet of roofing in the Western region of Canada, and found it interesting to be a part of a new research study of this kind, especially considering that Marine Roofing is the first in its field to be able to contribute to scientific research of this nature”. Field data consisting of wind speed, direction and pressures was collected continuously from October 2013. The main focus of the study was to compare and contrast the performance of the common roof edge metal configurations used by North American industries (ACC vs. CCC vs. DCC). This was successfully accomplished by concluding that there is minimal difference in the induced loads due to variation in the configurations. At the highest recorded wind speed of 60 mph (27 m/s), the roofing assembly and edge metal systems performed well without failure. Pedro Padron of Carlisle SynTec Systems, a leading company in commercial single-ply roofing systems, agreed that “having our product monitored for wind performance through such a thorough and detailed study by world class researchers at the NRC is an excellent way of knowing how our product performs in the field under the most extreme of conditions”. NRC’s analysis also showed the presence of negative pressure (suction) acting on all three faces of the roof edges. These findings differ from the current code specifications for parapets. As such, the design of the roof edge attachment should consider pullout forces from the parapet. Rob Harris, former Technical Manager at the Roofing Contractors Association of British Columbia (RCABC) said “This is the first collaborative project which took place with all major players of the roofing community – manufacturers, installers, building owners and researchers. As a regulatory body for roofing in BC, we offer a RoofStar guarantee, where technical information of this nature is vital for success of such a program.” The outcome of this study will have a major impact on the Canadian roofing community, including the validation of existing wind provisions in the National Building Code of Canada (NBCC) for

In addition, this study will contribute to the inclusion of the edge metal test protocol into the existing CAN/CSA 123.21 standard. This impact is broadened beyond Canada by proposals to the ANSI/SPRI ES-1 standard and ASCE-7 wind load document. ■

CRCA bulletin explains waterproofing The Canadian Roofing Contractors Association (CRCA) has issued a technical bulletin to explain the difference between waterproofing and roofing. “It is imperative that designers, architects and contractors understand the differences and similarities between roofing and waterproofing to ensure that the proper system is installed, because some materials are designed to function under either condition,” the bulletin notes. To add to the complexity between roofing and waterproofing, the National Building Code does not provide a clear definition of waterproofing, CRCA adds. The bulletin continues: Roofing and waterproofing membranes are used on decks as barriers to moisture entry into the spaces below. Both share some similar functional requirements, but others are quite different. For optimal performance it is important to understand the different loads and stresses waterproofing systems are exposed to when compared to roofing systems. Waterproofing can be defined as the treatment of a surface or structure to prevent the passage of water under hydrostatic pressure. The non-exposed waterproofing membrane is used to protect walls, floors and tunnels below grade from ground water and to protect

spaces below plaza decks that are on or below grade. The conditions of service for a waterproofing membrane differ from those of a roof. As a result, those physical properties that are important for a waterproofing application are not necessarily the same as those properties required for roofing. The following summarizes some of these differences. 1. The waterproofing is expected to perform for the life of the building. Unlike a roofing membrane, waterproofing membranes should be designed and built to provide maintenance free service, often for the life of the building on which it is applied. Roofs are typically easier to access and repair should problems occur. 2. The waterproofing needs to perform in a constantly wet environment. Depending on the amount and level of water in the ground, the waterproofing membrane can be in constant contact with ground water and wet soil. Roof systems, if properly constructed with adequate slope to drains, are usually only exposed to water for a short time. In addition, the hydrostatic pressure that they are subjected to is much less than that experienced by waterproofing membranes. Even

a ponded and poorly drained roof with 2 inches (50 mm) of surface water is only subjected to a pressure of approximately 0.07 psi (0.5 kPa). 3. The waterproofing barrier needs to resist ground chemicals. The contaminants to which waterproofing is exposed differ from those on a roof. Soil often contains acids, alkalies, salts and a variety of other contaminants that cause degradation of the waterproofing materials. The waterproofing system selected should be able to resist exposure to these chemicals over its expected service life. Although some roofs are exposed to contaminants from effluence exhausted onto the roof, their composition is typically known and preventive measures can be taken. The contaminants in soil often vary from location to location, and even by depth of the excavation. 4. The waterproofing barrier needs to resist construction abuse. Unlike roofs, waterproofing membranes typically do not have to be protected from foot traffic. However, they should be protected until excavations can be backfilled, or until the wearing course and overburden is applied. Although roofs are also prone to damage by other construction, it is more critical for waterproofing because of its inaccessibility. 5. The waterproofing also needs to be able to accommodate some movement in the substrate to which it is attached. Concrete walls and floors may experience settlement and shrinkage as it cures. In addition, decks may experience thermal movement and load deflection. The waterproofing membrane should be able to bridge small cracks and resist rupture from thermal expansion and contraction to some degree.

Roof stars GUARANTEED. BETTER.

Five companies honoured by RCABC RoofStar Guarantee program By Frank O’Brien

Henry Huber, president of Arcona Roofing, has a simple explanation when asked how his company has maintained an excellent claims-free record under the RCABC RoofStar Guarantee for a quarter century. The answer is in its motto: “Treat the customer’s building as if it were your own.” A small but experienced team – Arcona has five or six staff in the field – also means hands-on management that allows Huber to keep a close eye on all work, which has included contracts for new school construction and other demanding projects. Arcona, 46-year old, family-run firm, also holds the Certificate of Recognition (COR) from the BC Construction Safety Alliance. COR, developed by WorkSafeBC, is an incentive program that encourages companies to develop and maintain health and safety management systems that exceed regulatory requirements. “We always try to make sure every step is done just right,” said Huber, whose company has been an RCABC member for more than 30 years. Arcona was one of five member companies awarded for being claims-free under the RoofStar Guarantee program at the RCABC annual general meeting in December.

The other claims-free companies are sheet metal award winner Laing Roofing of Kelowna; Alpha Roofing & Sheet Metal of Kamloops; Heritage Roofing of Nelson; D.M. Henderson of Dawson Creek; and Continental Roofing of Delta, which is also the first Climate Smart registered commercial roofing contractor in BC. Laing Roofing, which has remained claims-free for 25 years, has been entrusted with some of the largest commercial roofing contracts in the central interior – including the landmark Sparkling Hills Resort near Vernon and

roofing of the Surgical Centre at Kelowna General Hospital. “We are doing a lot more architectural sheet metal panels,” said Laing vice-president Darran Light; work that won top honours last year in the Metal Architectural Design Awards. Like the other RoofStar Guarantee claims-free companies, Laing puts the customer first. “We always stand behind our workmanship,” Light said. “If there is anything that needs to be fixed or if a client is not satisfied with any aspect of the job, we will make it right, guaranteed.” ■

In the RDH analysis of a random RDH staff or RCABC accepted population of 267 flat roofs that inspectors at various times over the were under 10 years of age, 52 life of the roofs, typically before percent of these roofs were covered milestone warranty expiry dates or

during other reviews such as condition assessments, warranty reviews or depreciation report assessments. It was determined that 139 of these 267 flat roofs (52 percent) had an RCABC RoofStar Guarantee in place and 128 (48 percent) did not. This alone is a useful statistic that demonstrated the prevalence of the RoofStar program within the Lower Mainland flat roof marketplace, RDH noted. To determine if the roofs within these two databases had observed issues or potential claims, RDH then analyzed the observation data entered into the database by RDH staff, sorting the recorded issues into those that are potentially warrantable and those that are non-warrantable. When roofing observations were entered into the database a condition criticality was also assessed for each observation, ranging from normal maintenance tasks like drain cleaning and minor flashing repairs to more critical items such as roof leaks/staining, failed or damaged membranes, or severe ponding. Only critical items were then

flagged as “warrantable issues” while non-critical roofing maintenance or repairs were considered as “maintenance issues” and not counted in the analysis. The observations for each building were then counted and the number of buildings with roofing issues was totaled for each dataset. The results confirmed that the presence of an RCABC RoofStar Guarantee reduces the chance of warrantable roofing issues by approximately 42 percent. To confirm that the available sample of roof information provides a statistically significant result, RDH conducted a chisquared test (a statistical test applied to sets of categorical data to evaluate how likely it is that any observed difference between the sets arose by chance). This test determined at a 95 percent confidence interval that the presence of an RCABC RoofStar Guarantee reduces the frequency of roofing issues, RDH discovered. The RCABC Guarantee Corp. coverage is only available through members of the Roofing Contractors’ Association of BC, noted Judy Slutsky of RCABC. ■

A detailed and extensive analysis of the Roofing Contractors Association of BC’s RoofStar Guarantee has shown that it enjoys strong acceptance by the industry and has had a positive and significant impact on building performance, according to RDH Building Science Inc. of Vancouver. “The RCABC RoofStar Guarantee program reduced the warrantable roofing issues by up to 42 percent. The analysis demonstrates that the RoofStar Guarantee program appears to have reduced the number of roofing issues and likelihood of claims on flat roofs in the Lower Mainland of BC, as compared to roofs built without the guarantee,” concluded RDH principal Graham Finch and 10

Soprema opens new polyiso plant Drummondville, Québec – Soprema has announced the opening of the company’s first polyisocyanurate insulation manufacturing plant in North America. The opening ceremonies drew provincial and municipal officials as well as PierreÉtienne Bindschedler, President of Soprema and Richard Voyer, Executive Vice-President and CEO of Soprema North America. “This new plant is a turning point for Soprema Canada, because it allows us to expand our presence in the construction market,” said Voyer. “We now offer our customers complete solutions for roofs, for

which we manage all the production phases. Once again, we are proving our leadership and we are strengthening our vanguard position in this sector.” The groundbreaking was held in May of 2014 and the first CN freight trains arrived on site in November 2015. Summer 2015 was also a test and trial period for the production of polyisocyanurate panels. In October, the company gained the capacity to serve customers within a radius of 800 kilometres around Drummondville, which includes the Toronto area, the northeastern

United States, Montréal and the maritime provinces. Plant wins Real Estate Excellence award The new plant, designed and created by the consortium of ABCP Architecture and Dominique Blais Architecte, was built by the general contractor, Ronam Constructions, supported by a large number of subcontractors. The project won a real estate Excellence Award from the Urban Development Institute of Québec. This award, which honours innovation and contribution to the community, rewards those who have participated to the success of

BC to lead Canadian economy in 2016 VANCOUVER – A series of economic forecasts agree that British Columbia will lead the country in terms of economic growth in 2016, taking over from Alberta, which is expected to see its economy contract and return to only slow growth in 2017. The BC economy will grow by 2.8 percent in 2016, according to a CIBC World Markets report released November 23, with Ontario in second place at 2.4 percent. These rates of growth are well above the anticipated 1.9 percent growth nationwide. “Solid growth is in store for the central Canadian and more manufacturing intensive economies of Ontario and Quebec,” said CIBC World Markets chief economist Avery Shenfeld. “But the top spot is reserved for BC, which has been benefiting the most from overseas investment and from bordering some of the fastest-growing areas of the U.S. economy.” Reports from the Bank of Montreal, the Conference Board of Canada and Central 1 Credit Union have also ranked BC as the top performing provincial economy in 2016. ■

real estate projects in Québec. Winners are determined based on the quality of their real estate assets. Soprema seeks LEED Gold certification In terms of sustainable development, the Soprema project team put a lot of effort into adopting eco-friendly construction

and development practices for the new manufacturing plant. They included solar walls, LED lighting, white roofing, charge ports for electric cars, rainwater management, an improved ventilation system, energy efficiency, use of local materials, and replacement of paving asphalt with light-coloured roller-compacted concrete to reduce heat islands. Soprema hopes to obtain a LEED Gold certification for the plant. Polyisocyanurate is an insulation material (hydrophobic closed-cell foam) manufactured in flat, rigid panels coated on both sides. This product, with high thermal resistance, is used for many purposes, including roof insulation. “Indeed, polyisocyanurate is currently the best product on the market to meet climatic requirements of commercial, institutional and industrial buildings,” said a company spokesperson. Soprema is an international manufacturer specializing in the production of waterproofing and insulation products, as well as vegetative and soundproofing solutions, for the building and civil engineering sectors. The company operates in more than 90 countries worldwide. ■

Ski hill expansion OK’d A flurry of takeovers, permit approvals and planned expansions could translate into roofing contracts at BC ski resorts over the next few years. Here is why: The BC government has approved a master plan for a $1.5 billion ski resort expansion at Hemlock Resort in the Fraser Valley. Langley’s Berezan Group intends to build the all-season project, north of Chilliwack, in five phases. There would be an estimated $500 million capital investment in Phase 1, creating 1,153 full-time jobs. A further estimated $1 billion is expected to be pumped into the project through its full build-out, which would take decades. Since buying the resort in 2006, Berezan has invested $10 million into upgrading the existing infrastructure. In related news, a large U.S.-based ski resort developer has bought Mount Washington Alpine Resort, the only alpine ski resort on Vancouver Island. Pacific Group Resorts of Park City, Utah, have said they plan to “take Mount Washington to the next level.” The Garibaldi at Squamish Ski Resort, a proposal from Vancouver’s Aquilini Developments, could get a go-ahead under an environmental review early in 2016. If provincial ministers give the green light to the project, the proponents will embark on further public consultation. If approved, it would see the development of 22,000 bed units on Brohm Ridge, including thousands of homes and a number of new hotels. ■

Civic fees add to building costs

ROOFTOP DELIVERIES NOW AVAILABLE!

VANCOUVER â&#x20AC;&#x201C; The work yards and buildings of Metro Vancouver roofing contractors â&#x20AC;&#x201C; and other industrial operators â&#x20AC;&#x201C; represent a rapidlyappreciating asset that could cost millions of dollars to replace, according to a study by the the Vancouver-based Commercial Real Estate and Development Association (known as NAIOP). For a roofing material manufacturer moving into Metro Vancouver, the civic fees alone could convince them to look at smaller BC cities. An NAIOP cost study revealed that, while the construction costs of an industrial building have not increased dramatically in the Metro region, land values and municipal fees have soared. NAIOP used the following scenario to ascertain costs: rezoning a 5.5acre site to industrial use and building a 100,000-square-foot warehouse space with a small office area. The study found that the construction costs for such a building would be $79.50 per square foot, or about $79,500. The land would cost at least $6 million, however, and, depending on the municipality, total civic fees would add an average of nearly $500,000. Richmond has the most expensive total fees and charges for the sample building, at an estimated $1 million. Vancouver was the second most expensive at nearly $695,000, and the District of North Vancouver, where total municipal fees increased 96 percent in 2015 from a year earlier, would require $687,698 in total fees, the NAIOP study found. Municipalities with the lowest total fees are Burnaby, at $194,000 and Maple Ridge, where civic costs came to $160,126. â&#x2013;

27,000 new condo units to be built by 2018 VANCOUVER â&#x20AC;&#x201C; At least 27,000 new high-rise concrete condominiums will be built in Metro Vancouver in scores of new projects by 2018, according to a study by Urban Analytics Inc. And they will all be built, the consultancy firm said, because 87% of the condos have already been pre-sold. Much of the new construction will take place in Burnabyâ&#x20AC;&#x2122;s Metrotown and Brentwood areas, in Surrey Central and in the city of Vancouver. Across BC it is forecast that 30,800 new homes will start construction in 2016, similar to the pace of 2015. Most of the construction will be multifamily units, according to Canada Mortgage and Housing Corp. (CMHC). â&#x20AC;&#x153;Demand for new homes in the province will be supported by employment, population growth and low mortgage interest rates,â&#x20AC;? said Carol Frketich, CMHCâ&#x20AC;&#x2122;s regional economist. â&#x20AC;&#x153;Multiple-family homes will account for about two-thirds of housing starts.â&#x20AC;? â&#x2013;

Roofs eyed for housing Flat roofs could be claimed for housing, according to a Dutch architectural firm that has developed a lightweight modular system for use in cities around the world. Designed by architect Janjaap Ruijssenaars of Universe Architecture of Amsterdam, the houses are made with a steel modular structure and Meccano-like façade. Called the Tretis House, the components snap together and can be licensed to developers, the company explained. Universe can ship the plans and components anywhere in the world. Ruijssenaars said the Tretris system allows builders to link three modular steel structures to create one complete home that, with all exteriors transparent, offers wide sweeping views of its surroundings. Each standard house measures 1,883 square feet, and balconies and shutters can be added on. â&#x2013;

Measuring Up The measurement of roofs and buildings is now light years beyond a tape measure and camera By James Gillett

Another new technology is drones or unmanned aerial vehicles (UAVs). UAVs (Figures 3 and 4) would seem to be a perfect fit for the production of aerial imagery reports. Since they do not have to carry a human being, they can be smaller, lighter, and fly farther using less fuel. They can also fly at lower altitudes and, potentially, to more remote areas. The technology is evolving rapidly, but federal aviation regulations concerning drones are moving much more slowly. After regulations are established, there should be a multitude of uses within the industry, both on- and off-site, without having to get on a ladder. Future of onsite measuring There are additional onsite technologies that can be used now to aid in the measurement of roofs and buildings. One of the main tools that you probably have in your pocket—the smartphone—will be used in many new and creative ways to help you measure and identify roof and building conditions. One of the simplest uses for a smartphone is to determine the roof pitch. There are numerous apps that use the gyroscope present in every smartphone to determine the pitch—either from the ground or resting directly on the roof. Additionally, there are a host of “smart tools” such as distance measurement, levels, protractor, vibrometer, and even metal detector that use the existing sensors in your smartphone to provide a more complete analysis of a building. One of the most useful onsite technologies to come along is advanced vision capability. This technology uses a multitude of

Through a combination of offsite and onsite technologies, roof consultants, contractors, and adjusters can get a complete measurement of a roof or building. Existing and emerging technologies allow the digital recording of roof and building elements and the manipulation of the information to assemble exactly the needed report. Let’s look at where we are and where we’re going. Offsite The past five years have seen the Figure 1: Airplane or satellite imagery can be translated into rooftop measurements, as in this sample readout from SkyMeasure by CorLogic. widespread acceptance of aerial imagery reports for both residential Figure 2: What’s coming: Lidar uses and commercial roofing (Figure 1). a combination of light and radar to The technology has been proven build a super accurate 3-D model of reliable and is in widespread use by a roof almost instantly. both large and small businesses. The main source of data used for aerial imagery reports has been photographs taken from either an airplane or a satellite with the metadata being used to build the roof model. While this method is very accurate, it also requires a high degree of human interaction and is highly dependent on the quality of the photograph. The amount of foliage on the trees, the strength of the shadows, and the time of year of the photograph also affect quality. But there is a newer and potentially more accurate method of aerial measurement that will be used soon: lidar. the software could general maintenance.

The airport, which is handling more than 1.65 million passengers annually, has already expanded its airstrip. Construction of an airport plaza will be carried out in partnership with PatAIRa Holdings and will feature a gas station and convenience store. The second phase construction of a new car wash and detailing bay will begin in 2016. ■

Roofing contracts will land at airports Series of construction projects linked to BC air terminals By Dermot Mack

The construction of a large mall on Victoria airport land is just one of the airport-lined construction projects that may keep RCABC members busy over the next few years. Vancouver-based Omicron has signed an agreement with the Victoria Airport Authority (VAA) to be the exclusive developer of a 100,000-square-foot shopping centre on Victoria airport land in Sidney. The announcement came just days after the McArthur Glen Group opened an outlet mall next to Vancouver International Airport. The Victoria project would include a 62-year lease on the land,

Bentall office portfolio expected to sell for more than $1 billion. Photo: Ivanhoé Cambridge

Commercial real estate sales eye peak Vancouver could see its first billiondollar real estate sale in 2016 as the purchase of trophy properties push sales volume to a historic peak. The expected sale of the Bentall Centre office portfolio and the Royal Centre office and retail tower this year “will push overall dollar volume to previously unseen levels,” according to Avison Young. “Both assets will very likely set new benchmarks and may produce the first billion-dollar-plus commercial real estate transactions in Vancouver’s history,” Avison Young noted in a recent 2016 forecast. The current record price for a Canadian office tower is the $1.27 billion paid for the 68-storey Bank of Nova Scotia tower in Toronto, in 2012. The Bentall Centre is made up of four office towers in downtown Vancouver. Its majority owner, Montreal-based Ivanhoé Cambridge Inc., put it up for sale last year. The four buildings range from 21 to 35 storeys and together contain 1.5 million square feet of office space and 53,000 square feet of retail. The offering is expected to attract local and “global institutional investors” according to a statement from Arthur Lloyd, Ivanhoé Cambridge Executive Vice-President, Office, North America. Michael Gill, principal in the

Avison Young capital markets division said he would not be surprised if Asian-based offshore investors were among those attracted to the Bentall Centre offering. The Bentall 5 building was sold in 2012 for $400 million, or $686 per square foot, to a group of Canadian pension funds. At that per-square-foot price, Bentall Centre would be worth north of $1 billion, though most analysts believe it will sell for more. Bids closed in December for Royal Centre at the corner of Burrard and West Georgia Streets, but no sale information has been released. Brookfield Office Properties’ sole asset in Vancouver covers 589,000 square feet, including a 37-storey office tower and 91,000 square feet of retail space. The property is assessed at $287.5 million but was also expected to have fetched a higher price. Word on the street is the property is under contract with a successful bidder. Total commercial real estate sales through the first nine months of 2015 across the Lower Mainland reached a five-year high of $5.5 billion, up from $4.2 billion in the same period a year earlier, according to the Real Estate Board of Greater Vancouver’s commercial division. ■
