Celebrating Milestones

By Cheryl Mah

Pemberton (now Yarrow) building 1911.

T

he Vancouver Island Construction Association (VICA) recently marked two big milestones — amalgamation of the local Island construction associations under the VICA banner and the celebration of its 100th anniversary.

“There’s an air of excitement of being a member of the association and what we can do working together moving forward,” says Greg Baynton, CEO of VICA. Several attempts have been made over the past decade to create a single Island construction voice (originally there were four local associations) without luck. But last year through the efforts of several key people, the merger finally became a reality.

Baynton credits the Merger Task Team (Chris Erb, Sheldon Saywell, Don Cameron and Angus MacPherson), “They put in a tremendous amount of work and were able to get on the same page quickly to make the amalgamation possible.

And Pete White, our current chair has been outstanding at leading this newly formed board.”

The amalgamation better serves the industry on Vancouver Island, the Gulf Islands and coastal B.C. It allows for cross-island communication and collaboration on key member and industry

issues as well as networking opportunities that had not occurred before.

“As the Island has matured, it’s really boiled down to one market and not three anymore. We are able to be more effective and stronger as one organization,” says Baynton.

The various pieces for the newly-revamped organization have been falling into place over the past year with administrative changes almost complete. The new board consists of members from each of the previous associations’ boards.

“To celebrate our history and a new association on our centennial has really rejuvenated the leadership and there’s a sense of new beginning and new opportunities,” says Baynton.

VICA was founded in 1912 as a builders exchange and is one of the oldest not-for-profit construction associations in Canada. The association represents more than 500 member companies accounting for about 90 per cent of the Island’s ICI construction.

“In celebrating our 100 years, we’re going to have open houses up and down the Island and a big gala event in the fall,” notes Baynton, adding a big celebration was hosted by the Lieutenant Governor of B.C. in February. “Over 200 dignitaries attended the event to kick off our centennial.”

As CEO since 2006, Baynton takes great personal pride in the association.

“I came into this job thinking I’d do this for 5-6 years [and retire] and then this past year I’ve been thinking I can do another 5-6 years because I’m enjoying what I’m doing. I believe I’m making a difference,” he says.

The 57-year-old Victoria native has a diverse background in the industry with more than 25 years of experience owning and operating trade

hear for good

By Don Schouten, WorkSafeBC Manager of Industry and Labour Services—Construction

A

s someone who has spent a number of years on construction sites, I know that it can get loud — really loud. Most workers are probably used to it and simply tune it out, but what they may not realize is that they could be causing permanent damage to their hearing.

Prolonged exposure to noise can cause a permanent, untreatable disease known as noise-induced hearing loss. Around 300,000 B.C. workers are exposed to loud enough noise in their jobs to cause this condition.

When you’re around circular saws, generators, jackhammers, and power tools, exposure to noise doesn’t seem like a particularly worrisome hazard — but that’s what makes it so dangerous. This is especially true of young workers who may be more concerned about doing the job right rather than protecting their hearing.

In fact, a 2010 report showed that 28 percent of construction workers younger than the age of 20 weren’t using hearing protection. In 2009, it was only 20 percent. In both years, young workers in the construction industry reported higher rates of non-use for hearing protection than any other industry.

The good news is that the use of hearing protection overall in the industry has increased from 58 percent in 1978 to 88 percent in 2010. Plus, over the past 30 years, there’s been a decrease in the average hearing loss of construction workers who have had 16 to 25 years of exposure.

May is Speech and Hearing Awareness month in Canada so it’s the perfect opportunity to remind all workers about the importance of hearing protection. Remember, hearing protection must be worn at all times

when noise levels are above 85 dBA, which is the sound level of the average lawn mower. With all the trades using different types of tools and equipment, there is so much unpredictable ambient noise on a worksite that it’s not effective to only use hearing protection when a worker is actually creating noise.

Did you know that you are required to develop a hearing conservation program for workers whose noise exposure is greater than the limits set out in the Occupational Health and Safety Regulation? Or those workers who are exposed to noise are supposed to have hearing tests at least once every year? For more information about hearing loss prevention, FAQs, and useful resources, check out WorkSafeBC.com.

There is a section under the “Safety at Work” tab devoted entirely to hearing loss prevention.

I remember what it was like working on a job: of all the different things I needed to think about and focus on, protecting my hearing didn’t register very high on my list. But now, as I listen to the game on the radio or hear my kids laugh, I am deeply grateful that I made that effort to wear hearing protection. It didn’t seem like a big deal then but it makes all the difference now.

It’s said that silence is golden, but not when it’s all you hear.

Please let me know what you think of this topic or any construction safety issue. Call me at 604.214.6989 from the Lower Mainland or tollfree elsewhere at 1.888.621.7233. Or email don.schouten@worksafebc.com.

I’d like to hear from you.

VICA AGM

contracting and general contracting firms on Vancouver Island. Over that time, Baynton was involved with VICA as a contractor member and also served as a past board member and chair.

“Under the influence of my parents I was lined up to do an engineering degree at UBC but ended up working for a wall and ceiling contractor for a summer job and never turned back,” reflects Baynton.

He wound up managing that company by age 25 and bought out the company (with the original owner’s son) a few years later. His contributions to the industry were recognized in 1994 with the “Industry Person of the Year” award from the Northwest Wall & Ceiling Bureau.

In 1997, Baynton opened his own contracting company specializing in building envelope for new construction and building envelope remediation.

After selling his business in 2004, a chance encounter with good friends (and association members) led to him joining the association in 2006.

“I really believe in the association and what it stands for and what it means to the industry,” says Baynton about the decision. “It was good timing because I wasn’t interested in contracting anymore and I saw the opportunity as a way to transition out of the industry yet still keep me engaged in a really dynamic industry that I’m proud to be a part of.”

Moving from working in the industry to association management was certainly different, he admits.

“It was a bit of a transition working for a nonprofit and being answerable to a board but it has turned out to be very positive and I’m absolutely delighted to be here. There’s a lot of mutual respect between the board and myself and we work very 8

well together,” says Baynton.

“My experience has been broadened and I’ve met a lot of people I wouldn’t have otherwise met, particularly in government.”

He oversees a staff of eight operating out of the Victoria office. Another office is located in Nanaimo.

“We have excellent staff and function as a team. I’ve got great people working with me to make sure we’re addressing our members’ needs,” says Baynton. “I do what we refer to as the up and out so I’m out interacting with the industry and meeting people. For me to do that, we have to have a strong business service foundation here and we do.”

VICA provides an array of services for the industry from government relations and networking opportunities to educational seminars. At the core Excavation for Hudson’s Bay of these services is project destore 1914. livery and tendering available BidCentral has made the tendering process through BidCentral, an online planroom that provides a centralized destination for the com- more efficient and cost effective.

Connections “The provincial government is shifting their policy around procurement. There is a change in procurement policy that is going to really impact the industry on the Island if the government follows through with it,” says Baynton, declining to get into specifics only saying the association is actively engaging the government on the issue.

Another initiative he is working on is trying to create more collaboration with architects and owner groups on the Island.

“We’re wanting to form a contractor, owner, consultant group where we meet regularly and talk about challenges in the marketplace and work together to find solutions so that the broader industry isn’t reacting to problems — that we’re more proactive,” he says. “We really hope to develop that part of our membership and be more inclusive of the owner and consulting communities — an important objective of ours. We think it will be a mutually beneficial relationship.”

Of course, a pressing concern for the industry is the impending skills shortage. Baynton describes it as a “freight train coming down the tracks at us” and predicts the Island might feel it within 12 months. “It’s already happening in other areas like Northern B.C. where they are trying to recruit bodies,” he says.

The association is preparing for the demographic shift by engaging young construction leaders in every capacity of the organization.

“We’ve formed a group called Young Construction Leaders and invited them into strategic

planning sessions so succession planning for the association and for our membership is important,” says Baynton.

A more immediate concern for members is the low volume of work in the marketplace. The uncertain global economic conditions combined with the end of government stimulus spending have resulted in a noticeable slowdown.

“This year so far has been very much like the fall of 2011 which was a bit flat,” notes Baynton.

“Government isn’t spending much money right now so we’re really feeling that. When the infrastructure money dried up last year, we’ve been in a bit of a vacuum every since. Although we have commercial and niche condo activity, that hasn’t replaced the activity that was generated by the infrastructure stimulus.”

Despite the slowdown, there are encouraging signs that things might be picking up soon. Several projects are coming down the pipe including three new schools and a utility corridor for CFB Esquimalt. A recent announcement indicates the contract for BC Hydro’s largest capital project, the proposed John Hart project, should be awarded by summer 2013.

A number of major projects under construction are also helping to sustain volume including the Uptown mixed-use project and the helicopter facility for 443 Maritime Helicopter Squadron at Pat Bay. “Barring some major unforeseen international or financial event, I think we’re going to see some good growth in the second half of the year and

will finish the year on a really positive note and head into 2013 equally as strong. We’re optimistic,” says Baynton.

This is also a special year for Baynton personally. He is getting married in September.

Outside of work, he enjoys golf, boating and spending every minute possible with his 9-yearold granddaughter Maddie, “who never ceases to amaze me and teach me things about life.”

100 YEARS STRONG When the land was excavated to build Victoria High School in 1912, there were no giant cranes, no bobcats. As Vancouver Island grew at the beginning of the last century much of the muscle came from horses and men, not machines. A need to support those men and their employers led to the formation of the Victoria Builders Exchange.

For 100 years the association has served its members as they built houses, churches, office buildings, stores and schools on Vancouver Island. During the past century the island transitioned from local markets to one regional market leading to the amalgamation of three local island associations. Today the Vancouver Island Construction Association represents contractors and suppliers to the industry, providing education, advocacy, access to project opportunities and other benefits.

ast + Epp was the structural engineering firm for an iconic 19,000 sq. ft. visitors’ centre at VanDusen Botanical Gardens.

Targeting Living Building Challenge and LEED Platinum, the striking entrance point serves as an interactive education centre and welcome portal to revitalize public interest in the gardens. It includes lecture rooms, exhibition space, a cafe, and guest services.

Perhaps its most innovative feature is the dramatic free-form, organically-shaped roof structure, which metaphorically represents petals of an orchid, flowing seamlessly into the surrounding landscape like an extension of the garden itself.

The design team pioneered a wood solution for the new visitor centre in the interests of economy, sustainability, innovation, and to

H

atch Mott MacDonald was retained by the City of North Vancouver for design, management and construction administration for the 210m long Harbourside West Pedestrian Overpass and intersection upgrade, the newest section of the North Shore Spirit Trail.

This landmark project aimed to meet the requirements of multiple stakeholders, enhance community access in the area and provide a vital link over the railway tracks to connect Kings Mill Walk to West 1st Street.

Strict budgetary and short timeframe objectives were essential to successful delivery.

In addition, addressing numerous site constraints while creating an aesthetically pleasing form and considering environmental impacts, were key success factors.

The serpentine bridge consists of approach viaducts supported on ‘tree’ piers and a 42-m arch span to provide safe passage over three railway tracks. The design is functional, innovative and aesthetically pleasing.

Since the official opening of the overpass on June 9, 2011, there has been an average of 11,230 users per month; or 365 people per day.

meet tight time constraints. While similarly complex building forms have been achieved through the use of steel or concrete, this is believed to be the first example of wood use for such a complex form.

Seventy-one unique panels consisting of glue-laminated wood and standard dimensional lumber components were designed by Fast + Epp and subsequently prefabricated and created by StructureCraft Builders Inc. (a company owned by the principals of Fast + Epp).

The prefabricated panels were designed to have mechanical, electrical, acoustical and ceiling finish components pre-installed, to fast track construction, avoid mid-winter rain exposure and ensure a high-quality installation.

In recognition of their outstanding work, Fast + Epp won this year’s top honours from ACEC-BC. “We are very honoured and humbled to receive the Lieutenant Governor’s Award of Excellence from ACEC. We were in a category with many worthy projects so we’re happy to have come out on top. The judges obviously saw something in this small but exciting project,” says Duane Palibroda, managing associate at Fast + Epp.

liffwalk at the Capilano Suspension Bridge Park is the culmination of years of innovative engineering, allowing people access to the face of a 90 m cliff on a labyrinth-like series of narrow bridges, stairs and platforms. Cliffwalk serves as the medium to describe the importance of the water cycle through a series of interactive exhibits on this amazing 213-metre journey.

Morrison Hershfield was retained as the Engineer of Record and provided structural/ aesthetic design, construction inspection, erection, mechanical & electrical engineering and instrumentation/load testing services.

This role required MH to go beyond the typical design procedures used for conventional bridges/buildings and address the unique survey/construction techniques (the fabricator describes as ground-breaking) required in this one-of-a-kind park.

Longer than two football fields, Cliffwalk was constructed using a total foundation area of only 11 m². The construction allowed the reclamation of 8,100 m² of previously unusable park land, a net benefit of more than 735 per cent!

soft engineering award of Excellence Kerr Wood Leidal Associates Ltd. | Partington Creek: A New Watershed Development Planning Process, Coquitlam

T

he lower third of ecologically rich Partington Creek watershed is planned for a $1.5 billion greenfield development. Over the next 20 years, what is now forested land will become a new town centre, home to about 12,000 people.

Kerr Wood Leidal Associates developed an Integrated Watershed Management Plan for the City of Coquitlam, which charts a new and better way to plan sustainable communities. The common approach to land development is to first create land use plans and then engage engineers to lessen the negative impacts of development. This reactive approach limits the opportunities and solutions available.

The multidisciplinary team worked together and changed the initial land use plan to maximize environmental protection and rainwater management. The result is a net environmental benefit for the watershed post development without any reduction in the development’s population, livability, or financial pro forma.

The IWMP calls for sustainable infrastructure that goes well beyond regulatory requirements in preserving this undeveloped watershed’s ecology.

he renewal of the UBC Biological Sciences Complex reveals the tremendous potential in aging building stock. This $45 million project was fast-tracked through design and construction in only 19 months to meet the federal stimulus funding deadline. The 16,000m2 buildings received all new mechanical systems and a full environmental abatement, complete envelope upgrade, and seismic reinforcement.

Applying innovative, environmentally-sensitive design to the rejuvenation of older buildings can represent a more economical and sustainable option than new construction. A creative, collaborative approach to the building systems design has helped transform a tired building into an uncompromising, first-class research facility — providing a compelling example of efficient, low-impact redevelopment.

Feature Project

A Digital Future

By Cheryl Mah

V

ancouver has evolved over recent years to become recognized as a leading digital media hub in Canada, home to many companies such as Electronic Arts and Disney/PIXAR. A new educational facility on the Great Northern Way Campus (GNWC) will not only attract the best and brightest in digital design but will also become a catalyst for turning the site into a long envisioned industry district for creative and digital sector firms.

The Centre for Digital Media, currently under construction, will be a state-of-the-art training facility for the digital arts field (gaming software, animation, film). It will house the Masters of Digital Media (MDM) program, Canada’s first professional graduate digital media degree. The ground floor provides

academic space while the three upper floors will have 76 units of student housing.

“We are proud and excited about this new facility, part of our plans to make Great Northern Way Campus an important part of Vancouver and British Columbia’s digital economy,” says Morgan Sturdy, GNWC board chair.

Designed by Musson Cattell Mackey Partnership (MCMP), it is the first new building for the campus and marks a major step towards transforming the 18.5 acre site in the city’s False Creek Flats. The land was donated by Finning International in 2001 to UBC, SFU, Emily Carr University and BCIT. The campus is managed by GNWC Trust for the four academic partners.

“The campus has been quite dormant since it was bequeathed to the four institutions.

Hopefully this building will start to change that,” says Mark Thompson, MCMP partner in charge of the project. “The long term master plan is for the neighbourhood to become a digital media cluster.”

The MDM program is currently housed in the existing digital facility next door.

“It’s a building that we renovated a few years ago — an old industrial building from the Finning era when it was an industrial site. They’ve outgrown the facility so that was the genesis of the need for the new building,” says Thompson.

Locating the new building in close proximity to the existing facility (which will be repositioned) was viewed as important in order to provide space for graduating students to incubate businesses.

Feature Project

“There’s office space within the existing building that will be used to transfer people out of the program into the real life world of digital media,” explains Thompson.

Another key objective was to bring student housing onto the site, which has been called a “digital dormitory.”

“The MDM program has an international profile so you do get students from other countries coming and having them right on site is a huge advantage and helps to create a vibrant learning environment,” says Thompson.

The new building is considered to serve as a gateway function to the site so it needed to have a unique iconic image, notes Thompson. “It is always challenging to pioneer on a site like this because the rest of the site is mostly industrial buildings or vacant land.”

Inspirations behind the design included movement and a “technology ribbon”.

“We integrated the idea of a ribbon into the building, which is a theme that also influenced the renovation of the existing building,” describes Thompson. “The wood cladding on the north and south facades are seen as evocative of the West Coast and having a tactile sort of foil to the metal ribbon which symbolizes industry.”

The shape of the building is also meant to evoke transportation metaphors.

“The site has a transportation history and it’s in a transit corridor so the shape is meant to reinforce the idea of movement and communication,” says Thompson. “Integrating movement into the architectural image of the

building was seen as a positive way to create a more striking expression.”

The exterior features an angled wall on the western end of the site which not only creates a unique architectural profile but also serves as a digital screen for projecting video or images.

“This building is predominantly white and wood so because we’re able to project onto the white surface, that’s where we’ll add colour and the animation for the building,” notes Thompson.

The new centre will have 16,000-square feet of teaching, meeting and studio space on the ground floor. Because of the nature of the MDM program, the design focuses on smaller collaborative spaces for students to work together on projects.

“We’ve built a lot of flexibility into the planning of the MDM space itself — lots of moveable walls — to create different types of learning environments rather than your traditional classrooms and lecture halls,” says Thompson.

The task of making the contemporary design a reality was placed in the hands of VanMar Constructors. VanMar broke ground on the 51,000 square foot facility in late June 2011 with substantial completion set for this August. Manpower is expected to peak at 60 on site.

Hansen Ng, GNWC director of development, reports the project is about 55 per cent complete as of late March and is on time, on budget.

“After the insulation is in, the focus of the work will be substantially completing the interior finishes,” he says.

The four storey structure is slab on grade ground floor concrete and second, third and fourth floor wood frame on top. The exterior is a combination of metal cladding and wood.

Main challenges included poor soil conditions (requiring a pipe pile foundation) and the unique cantilevered elliptical design.

“Given that we are on a tight schedule and having to work through that many custom design details was a bit of a challenge,” says Ng. “False Creek Flats is on fill so we knew it walking into the project and it meant an upgrade to the geotech design.”

Designed to meet a LEED Gold certification, the building features a number of sustainability strategies including geothermal heating, solar hot water, storm water management and a green roof on the lower level. The building profile is designed and oriented to allow maximum daylighting.

“The key feature is energy performance,” notes Ng. “We have a solar supplemented geothermal system that is designed to take on 100 per cent of the hot water needs. In addition to domestic hot water, we have radiant floor heating. It will mean big energy savings.”

The new $13 million centre will open its doors to students in September 2012.

pcor Tower is a 66,974m2, 29-storey office tower. The project is the first high rise building to be built in Edmonton in more than 20 years and is the first building of an eventual four block development known as Station Lands. The tower is comprised of a two storey retail podium, 26 floors of office space, and a mechanical penthouse floor. There are four levels of below grade parkade with a total area of 28,288m2.

The building is expected to use 121kWh/m2/year of energy, a 41.4 per cent energy use reduction as compared to ASHRAE Standard 90.1. The 28 construction business

Earth Tubes Epcor Tower takes advantage of a unique system of earth tubes used to pre-heat and pre-cool the building outdoor air. The principle of earth tubes is a geothermal exchange between the air and the surrounding earth using a thermally conductive material as a separation. The greater

Earth Tubes — Courtesy of AECOM

By Jillian Pederson

Mechanical the surface area in contact with the ground, the greater the heat transfer will be. Because the ground temperature essentially remains constant below the frost line, the ground can be used to heat the air in the winter season and cool the air in the summer season. In order to maximize the rate of heat transfer, it is ideal to flow the air at a low velocity through the earth tubes to provide adequate lag time for the heat transfer to occur.

The earth tubes are designed to utilize as much of the building structure as possible in order to minimize the additional costs required to build them. Two vertical intake shafts run down the exterior of the parkade walls. These intake shafts are constructed with glycol heating lines inside the concrete to ensure freezing does not occur when cold air is being drawn in. Once the shafts have passed the lowest parkade level, they turn 90° to continue horizontally below the parkade structure. The earth tubes then form a loop around the building’s core before connecting to the main tower air handling unit which provides the rest of the conditioning.

The earth tubes themselves are built as a combination of precast concrete pipes and poured concrete plenums with internal columns for structural support. The plenums are 9.5m wide and 2.5m high, with an airflow rate of 18,877L/s per earth tube. The earth tubes are designed for the maximum load, which in Edmonton occurs in heating mode.

The desired temperature rise is from -34°C to 6°C, 6°C being the constant ground temperature below the frost line, resulting in a 40°C delta.

Using a heat transfer rate of 0.5°C/m, each earth tube needs to be a minimum of 80m in length. The actual length of the constructed earth tubes are 116m and 97m.

This provides significant savings on the ventilation heating and cooling loads. An 8,760-hr annual analysis was used to calculate the energy saved from the earth tubes. In heating mode the earth tube saves 1,473,994kW/year and in cooling mode it saves 84,874kW/year. This equates to approximately CDN$51,687/year in cost savings.

Exhaust Air Heat Recovery In order to capture waste heat from the general exhaust system, a heat recovery unit is located at the exhaust outlet. This recovery unit captures the heat in the exhaust air and returns it to a heating coil in the main tower air handling unit via a glycol run-around loop. The exhaust air heat recovery is capable of providing a 19°C temperature rise for 37,754L/s of outdoor air. This lessens the load on the main heating coil in the tower air handling unit, thus lessening the load on the boiler system.

Winter Free Cooling

Exterior — Courtesy of Phil Stark (Ledcor)

In a climate such as Edmonton’s, there is an opportunity to take advantage of winter free cooling. During the winter months when the outdoor air wet bulb temperature is less than the chilled water temperature, in this case 6.7°C, the entire cooling load can be achieved through the cooling towers. This is accomplished by providing cooling towers capable of running year round with integral immersion heaters. In free cooling mode, the chillers are turned off and bypassed completely. The chiller plant is currently sized at 6,400kW with the possibility for future expansion. Winter free cooling can be used 39 per cent of the year in Edmonton. This is a significant load reduction on the chiller system.

Glycol from the second heat exchanger is used to heat the intake shafts of the earth tubes to prevent freezing. The heating system is currently sized for 7,719kW with the possibility for future expansion. The stack condensing system increases the overall boiler plant efficiency from 85 per cent to 95.5 per cent, a difference of 998kW of input power, by capturing both sensible and latent heat.

Conventional boilers are used on this project in conjunction with a stack condenser.

Conventional boilers are used on this project in conjunction with a stack condenser. All of the boilers are breeched together in order to combine the flue gases prior to entering the stack condenser. Heat in the flue gases is extracted in two separate heat exchanger coils within the stack condenser: one using water and one using glycol. The flue gas temperature is lowered below its dew point, resulting in condensation and extraction of latent heat, in addition to the sensible heat. Water from the first heat exchanger is re-

Epcor Tower uses dual flush water closets which have a maximum flow rate of 6Lpf. The reduced flush is 30 per cent of the maximum or 4.2Lpf. The building also employs low flow urinals, low flow lavatories, and low flow shower heads.

Rainwater is captured and stored in a 725m3 tank located under the parkade structure. Precipitation is captured from various roof levels, the balconies, and the street level plaza areas.

The rainwater is then treated and reused to flush water closets and urinals at an estimated 4,439m3/yr. The combined result is a 63 per cent water use reduction compared to a conventional building.

Fire Protection Systems

by Cel Chow

Multi-Level Atrium with Smoke Management System

I

n an effort to ensure that the welfare of the general public is served, building codes and regulations are used to determine the proper building design and construction methods.

The basic objectives of fire protection requirements in the building code are to safeguard life and property. In general, these objectives are achieved in buildings by providing a safe means of escape or a safe refuge for occupants in the event of a fire, by designing the building to limit the growth and spread of fire and smoke, and by providing fire detection and alarm systems and fire suppression systems.

Types of Fire Suppression Systems There are three types of fire suppression systems in buildings:

1. Water Based Fire Suppression Systems A manual fire suppression (standpipe) system is required in a building that is more than three storeys in building height. This standpipe system is intended to provide a means for fire responders to fight a fire inside a building. The standpipe system provides a hose connection at each exit in the stairwell and the fire department will use their hoses and nozzles to set up the fire operation stations in the stairwell before attacking the fire.

The building code requires sprinkler protection for certain types of occupancies and construction in order to reduce the risk of fire in the building. An automatic sprinkler system is a system of pipes or tubes with sprinklers connected to a permanent water supply. The heat of a fire will cause the sprinkler to open and discharge water onto the seat of a fire. The sprinkler system, as required by the building code, is designed and installed in accordance with National Fire Protection Association (NFPA) 13, Standard for the 30 construction business

March/April 2012

Installation of Sprinkler Systems. However, residential buildings that are four storeys or less in building height, will have their sprinkler system designed and installed in accordance with NFPA 13R, Standard for the Installation of Sprinkler Systems in Residential Occupancies up to and including Four Stories in Height.

There are several types of sprinkler systems available. Wet sprinkler systems with piping normally filled with water are used in residential and heated buildings. Dry pipe sprinkler systems with piping normally filled with pressurized air are used in unheated areas such as unheated buildings, parking garages, attics and other exterior areas. Preaction sprinkler systems with piping normally filled with air and the control valve operating upon the receipt of a signal from a fire detection system are used in museum, art gallery, high value electronic equipment, data rooms and storage freezers. This type of system is designed to discharge water from sprinklers by opening the control valve through the preaction sprinkler detection control system. This minimizes the chance of the sprinkler system accidentally discharging water. Deluge sprinkler systems employ open sprinklers. All sprinklers in a deluge system discharge water once the control valve is activated by the sprinkler detection control system.

This type of system is designed to protect large instantaneous fires in industrial establishments such as hydro substation transformer fires, flammable liquid fires in flammable liquid storage warehouses or tank farm facilities.

In the late 1980s, a special sprinkler was developed to protect glazing partitions to provide an equivalent to a listed two-hour vertical wall assembly. This sprinkler permits the building design team to improve the architectural design by using sprinkler protected glazing partitions in areas that require a fire-resistance rating of up to two hours. This allows flexibilities in the building design for aesthetic or security reasons.

2. Clean Agent Gas Systems Clean agent gas systems are used for the protection of high value equipment such as electronic products, computers and data storage. Gaseous fire suppression involves the use of inert and chemical gases, creating a total flooding condition in an enclosed room, and therefore does not result in water damage to the properties that they protect. The most common clean agents in Canada are Inergen, FM200, NOVEC 1230 and carbon dioxide systems. A fire is suppressed by reducing the oxygen content in the room or by removing the heat from the fire through the process of rapid gaseous agent expansion. The reliability of these fire protection systems relies on the sophisticated control systems detecting the presence of a fire and operating the shutdown sequences of equip-

ment power and room integrity systems (doors, fire/smoke dampers). The building codes do not accept these gaseous fire suppression systems as replacement of sprinkler systems in the protection of building structures, because, unlike a continuous water supply, they have only a “one-shut� single discharge capability.

3. Wet and Dry Chemical Systems Wet chemical fire suppression systems are usually used to protect commercial kitchen exhaust hoods and industrial cooking facilities. Dry chemical fire suppression systems are used to protect industrial operations involving flammable and combustible liquids, such as spray paint booths and flammable liquid dispensing stations. These systems are generally automatic systems controlled by a fire detection system using heat detectors or fusible links with a spring loaded mechanical release system.

Dry chemicals are also used as fire suppression agents for portable fire extinguishers.

Automatic Sprinkler Systems In addition to reducing the fire risk in a building, automatic sprinklers add environmental benefits by reducing the levels of air and water pollution, water usage and overall fire and water damage. In general, only one to two sprinklers open in a fire. The sprinklers suppress or control the fire at an early stage. On average, early fire suppression by the sprinklers reduces the peak heat release rate to as low as 300 kW, while a fire in a building without sprinkler protection could reach a heat release rate of 13,200 kW. The average quantity of water discharged from the two sprinklers is not more than 100 US gpm, while a single fire hose can easily discharge 250 US gpm to attack a fire in a building without sprinkler protection. Flashover occurs at approximately five minutes in an unsprinklered room fire while flashover does not occur in a fire in a sprinkler protected room. It is expected that more than one fire hose is needed for full extinguishment of a fire during a manual fire suppression operation. It is clear that sprinklers can significantly reduce the amount of contaminated air emission from a fire, fire protection water usage and runoff to the environment.

The provision of automatic fire suppression systems in buildings not only reduces the fire risk and enhances the fire and life safety of the occupants and the property, but also reduces the negative environmental impacts that can be caused by a fire.

Mechanical

Improving Insulation Practices

By Lee Loftus

A

timely opportunity exists in British Columbia building construction to save money, reduce energy consumption and shrink our carbon footprint.

That opportunity is the typically unseen insulation on pipes and ducts of heating and cooling systems, known as mechanical insulation.

Based on a survey of peer-reviewed research and trade journals, interviews with mechanical insulation professionals and energy modeling of three different building types, actions have been identified that can be taken by the provincial government, utility companies, local government, developers, engineers and building owners/operators.

These changes could save millions of dollars in heating and cooling costs, while eliminating thousands of tons of greenhouse gas emissions each year.

And the cost of mechanical insulation is typically only one per cent of total building construction budgets. That makes it one of the simplest and most cost effective ways to save money and our environment.

Unfortunately, concerns have increasingly come to light about poor installation practices in mechanical insulation for building construction in B.C. Local and global goals to use energy more wisely and reduce greenhouse gas emissions heighten the urgency and opportunity for taking action.

Identifying the problem and proposing solutions was the task of a new White Paper on mechanical insulation independently authored by HB Lanarc Consultants and commissioned by the BC Insulators Union Local 118 [Also known as the International Association of Heat and Frost Insulators and Allied Workers -IAHFIAW].

The aim was to more formally recognize the opportunity to meet energy and greenhouse gas reduction goals through reversing the trend of poor mechanical insulation installation practices.

BC Insulators is concerned because its members install the mechanical insulation for many multi-unit residential and commercial buildings in B.C. Those members, through partner organizations like the B.C. Insulation Contractors Association (BCICA) have written training curriculum for mechanical insulation used by similar organizations across North America.

Mechanical insulation, as a key component of a building energy system, plays an important role in:

• Improving energy efficiency, thereby mitigating greenhouse gas emissions and moving toward sustainable energy use; • The economic performance of buildings, including minimizing spending on energy and ensuring durable buildings; and • Health and safety — through fire stopping and protecting workers/building occupants from unhealthy indoor air quality (moisture-caused mold) and burn (exposed pipes).

Ironically, mechanical insulation as a significant solution to all these issues has been largely ignored in B.C., a province that rightly has some of the most aggressive greenhouse gas reduction targets in the world.

Energy efficiency requirements have increased in the B.C. Building Code, and much more aggressive changes are anticipated, while many B.C. local governments are also strongly encouraging green, energy efficient buildings.

But mechanical insulation has not yet been identified as a priority and, unfortunately, achievement of energy performance targets is being hampered by poor mechanical insulation installation practices.

Yet building owners, operators and tenants could save millions of dollars annually simply by improving mechanical insulation practices.

The challenges to implementing effective mechanical insulation are many, and include significant gaps and omissions in the Model National Building Code, the BC Building Code and ASHRAE Standards, and industry best practices manuals, all detailed in the White Paper.

Regrettably, there is also very limited oversight of building codes and best practices by regulatory bodies, leading to significant non-compliance and mechanical insulation deficiencies.

As identified from research cited in the White Paper, they include: • Outdated or incomplete engineering specifications, or lack of knowledge of best practices by engineers, especially for newer, high performance and low-temperature systems; • Problems due to unqualified installers and inadequate training; • Lowest cost tendering and “value engineering”, reducing costs below what is necessary

for best practices, particularly when the developer is not the eventual owner or operator; • A perception among some developers and engineers that mechanical insulation is not a critical building component; this may be in part due to lack of focus on it during education; •P oor quality, lower cost insulation materials on the market; •C hallenges related to engineering field review, including assessing whether installations meet code and design specifications; •A fragmented design and construction process where engineers and installers do not typically work closely together; and •T ight construction timelines and focus on drywall completion, which can prevent inspection of some systems.

Based on the results from the interviews with industry experts and analysis of policies and codes within and external to B.C., the White Paper developed a set of recommendations in order to improve mechanical insulation practice in B.C. It is clear that a unified and compelling set of changes at the senior government level, supported by local government policies, is needed to achieve a consistent, improved level of performance across B.C. The reasons for insulation deficiencies are complex and interrelated; therefore a single solution, such as regulatory changes alone, will probably not result in the best possible outcomes.

To address these issues, two mutually reinforcing strategic elements are recommended: •P rovide a consistent regulatory framework across B.C. that embeds standards for mechanical insulation in building codes; and •B uild capacity in local government and industry to maximize compliance with codes, standards and best practices, both existing and future.

Much attention is being paid to significant improvements in construction practices aimed at achieving “green buildings” but one of the simplest and most cost effective methods — mechanical insulation — has to date been largely ignored.

That should change as knowledge spreads.

Water & Waste

Designing a Trash Hub

An award-winning facility drives Edmonton’s ground-breaking waste management centre. By Simon Chan

N

ot long ago, the prospect of keeping 90 per cent of a major city’s waste out of a landfill would have been deemed a lofty dream. By 2015, however, it will be a reality for Alberta’s capital city.

The Edmonton Waste Management Centre is a highly innovative solution to the ever increasing amount of waste produced by today’s cities, and a key part of the overall centre is the Integrated Processing and Transfer Facility. It is here that the bulk of the city’s waste will be brought for sorting and distribution, and is a key facet to the integrated system that includes composting, processing recyclables, electronic waste processing, power production from landfill gas, environmental protection and monitoring, construction and demolition recycling and even the production of alcohol fuels from processed waste.

Stantec partnered with the City of Edmonton, HIP Architects and Clark Builders to build the Integrated Processing and Transfer Facility, which by 2013 will process 350,000 tonnes of material from both residential and commercial waste streams.

A team of designers from Stantec addressed the numerous challenges surrounding a project of this scope and complexity in the areas of civil, structural, mechanical and electrical engineering, while providing project management for the new facility.

A key challenge the design team faced was building a facility that would withstand the rigours of a major city’s waste disposal needs.

(Imagine the level of industrial traffic at only one landfill.) Specified high-strength concrete was used by designers to ensure heavy abuse doled out by industrial equipment, like bulldozers, would not result in unsustainable maintenance costs.

To achieve the level of durability required, while maintaining its versatility, the building is an intricate combination of pre-engineered structure, cast-in-place concrete and structural steel framing. It is divided into two areas with a six metre difference in elevation. The first is a commercial tipping floor, which absorbs the bulk of heavy traffic. The tipping floor slab was constructed of high strength concrete to withstand repeated heavy equipment abrasion and is surrounded by 3.6 metre cast-in-place push walls.

The second is a multi-use pre-processing and sorting room that distributes waste throughout the Waste Management Centre and where the refuse for the future biofuel facility will also be derived. A network of sorting trammels has been designed into the structure, supported on nine metre high piers that are surrounded by elevated structural steel platforms. The innovative use of space enabled designers to fit a variety of complex tasks, within a single facility, ensuring

the efficient distribution of the sorted waste throughout the centre.

Another major challenge for the design team was maintaining the temperature in the facility.

A mechanical system had to be developed to ensure the ambient temperature in the tipping floor area did not drop below 5 ºC. The freezing and thawing of the concrete foundation would have an adverse effect on the longevity of the structure. In addition, the machinery throughout the facility must remain at optimum operating temperatures to avoid breakdowns and inefficiency. With the extremes of an Alberta winter and constant opening of large overhead doors to accommodate industrial traffic, this was no easy task. The design team developed a highly efficient building envelope, coupled with a ambient temperature monitoring system to automatically regulate the building’s heating system.

For its design, the Integrated Processing and Transfer Facility won the 2011 Consulting Engineers of Alberta Award of Excellence for Buildings Engineering.

The end result of this integrated design and project management process is a state-of-the-art facility that serves as the hub for Edmonton’s industry leading waste management centre.

Water & Waste

Toward Net Zero Water

By Mona Lemoine

A

s the urban population swells, the need for water and wastewater services expands. This alone represents a problem. Coupled with aging water supplies and outdated wastewater treatment infrastructure, unsustainable water use patterns and climate change, we now find ourselves face to face with a serious threat to a precious resource.

While the green building movement has worked hard to change the way people view water, a widespread adoption of more integrated systems that include supply, treatment and reuse of water at the building and neighborhood scale is necessary. This requires a major shift in how buildings are conceived, designed, regulated, built and operated. We must move toward a “soft path” for water management through decentralized and distributed-scale systems, which offer alternatives for communities willing and/or forced to re-think their present path.

CHALLENGES A variety of challenges exist for net zero water projects that seek to use best practices around water conservation, rainwater harvesting, greywater and blackwater reuse in distributed and on-site systems: Regulatory barriers Water is regulated across multiple jurisdictions and agencies.

Barriers stem from the current bias for centralized water supply and wastewater treatment and the associated lack of an authoritative body with appropriate powers to operate, manage and regulate decentralized approaches. To create support for net zero water projects, a major shift from our current regulatory framework is necessary. A more holistic approach to regulating water and waste is needed at all agency levels in order to support innovative projects and drive future policies.

Financial barriers Net zero water projects rely upon on-site or distributed systems for water supply and treatment otherwise managed at the municipal level by publicly-owned utilities.

As such, the cost burden for supply and treatment systems — as well as their ongoing operation, maintenance and replacement needs — are shifted from the utility to the individual project owner.

While this can create financial barriers for project owners, unique opportunities exist for utilities to develop fee structures and incentives to support the transfer of capital cost, expense and revenues to offset an owner’s upfront investment in on-site water systems. Removing regulatory barriers to decentralized systems can help spur market innovations and new products available to designers and homeowners pursuing net zero water strategies, thus bringing down upfront costs and reducing life cycle cost payback periods.

To create support for net zero water projects, a major shift from our current regulatory framework is necessary.

Cultural barriers In addition to regulatory and financial barriers, public perception about the safety of water reuse and on-site wastewater management present significant obstacles for net zero water projects. Such fears are rooted in our historical management of water and waste and the resulting public health issues that have surfaced. Today, education is needed to assure the public of the safety of modern decentralized water systems and inform them of their environmental, social and economic benefits. Addressing cultural barriers around decentralized water systems requires a shift in the fundamental ways in which we view water and human waste. Instead of the current “out of site, out of mind” thinking, we need to take ownership not only of how we use water inside our buildings and for irrigation, but how we operate, maintain and replace on-site systems over time. In doing so, we will treat water as the precious resource that it is.

BEST MANAGEMENT PRACTICES Best management practices (BMPs) for decentralized water systems emphasize closed-loop systems, ultra-efficient measures to reduce system demand, small-scale management systems, fit-for-purpose water use and diverse, locally appropriate infrastructure. Establishing a water balance (a numerical account of how much water enters and leaves the boundaries of a project) is a critical step in understanding water flows on-site. The most successful design strategies are those that not only seek equality between water supply volume and building demand, but also address long term financial and public health risks and provide educational opportunities for building occupants.

The following are innovative projects using best practices for decentralized and distributed water strategies from our region and around the globe.

Greywater Reclamation & Reuse Center for Urban Waters, Tacoma, Washington, includes a rainwater harvesting system coupled with captured greywater from the building to achieve an estimated 46 percent reduction in potable water use. In addition to the greywater reuse system, the Center will showcase a laboratory for collecting, monitoring, and assessing water quality effectiveness of low impact strategies.

Composting Toilets C.K. Choi Building for the Institute of Asian Research was the first of its size to install composting toilets in North America, eliminating the need to connect to the campus sewer system and reducing potable water demands by over 375,000 liters (99,000 gallons) per year.

Membrane Bioreactors The Vancouver Convention Centre houses a membrane bioreactor designed to treat 20,000 gallons of wastewater generated by the facility each day. All of the building’s treated wastewater is recycled onsite for flush fixtures and to irrigate a six-acre green roof.

Water & Waste

Converting Waste to Energy

By Andy Harris

W

aste to energy, or energy from waste, is a curious blend of three Canadian industry sectors — logistics, processing and energy. Fortunately for us others have done the homework and we can benefit.

Waste management is the key logistical component and however you look at it our waste management practices reflect the fact that we have room in Canada, lots of it. We also have lots of waste — estimates vary yet allowing one tonne per family per year is one estimate that doesn’t even reflect construction/demolition, commercial, biomass, agricultural or industrial waste. The long-standing practice of just burning or depositing waste in landfills that are now reaching capacity or getting obsolete is proving limited and in many cases short sighted — the old thinking was out of sight out mind. There will always be some waste that has to go to a well-managed landfill, and if recycling makes sense after trucking costs are considered, the rest is a valuable fuel source.

Recovering energy from this waste moves the issue of disposal into an opportunity for generating income from heat or power sales. This is becoming increasingly important and even though Canada lags behind best-practice we can be certain that increasing costs and legislation will demand higher environmental standards of waste disposal and pressure industry and local municipalities to reduce their quantities of waste generation and landfill.

34 construction business

March/April 2012

Ultimately we will move to a reduction in the amount of waste created, together with a substantial increase in the amount of waste re-used and recycled. This means maximizing cost effective pre-treatment and processing of waste before disposal and where disposal requires combustion, that it is done in the most efficient way possible. In Kelly Lake in North Eastern B.C. the local Metis settlement is deploying a biomass to energy facility to generate some 15MWe to the BC Hydro grid using mostly pine beetle kill wood and forestry waste wood as feedstock fuel — wood that would normally be burned.

Combined heat and power (CHP) is the most energy-efficient process for converting waste into useable thermal energy, the key outputs of waste to energy facilities usually being heat or steam with some producing electricity. CHP using modern iterations of well-proven technologies offer significant improvements on a facility’s energy efficiencies compared to old burning or incineration equipment. Newer facilities achieve +80 per cent efficiency in converting waste into thermal energy with 95 per cent reduction in waste volume to produce inert harmless ash that itself can be reused as an aggregate supplement. Approximately two garbage truck loads (30 tonnes) of regular Canadian municipal sold waste (household garbage etc) can produce some 6MWt of thermal energy or 1MWe of electrical energy for export to the grid. We are seeing a drive to the provision of thermal energy from

waste replace ever-increasing costs of fossil fuels — especially for industry. Alongside clean waste destruction this cost saving or removal of pain, is in many cases overriding the production of electricity as the economic rationale. As one of my more lucid colleagues puts it in one of his more eloquent moments “It’s a beautiful thing, using what we don’t want (waste) for what we really want (energy)”.

In some cities there is so much waste that it has to be mass burned in vast facilities. We’re seeing a shift to a more decentralized or localized model where waste is dealt with close to where it is generated and thermal or electrical power is produced close where it is needed.

This and effective waste management is possible with clean technology. 1.5 tonnes of garbage per day in Old Crow northern Yukon is now cleanly destroyed in a mobile gasifier system rather than going to a simple landfill.

We are seeing towns, industry and city districts moving away from very large regional solutions to more localized scalable solutions. Driven by wiser policy, public concern over mass burn emissions and rising trucking costs this model is deemed more effective especially given the clean waste to energy technologies systems that have had to navigate approvals from the uber-stringent EU emissions controls. In fact praise is needed once again for the Scots’ diligence — add emissions control management to banking, distilling and engineering. The Scottish Environment Protection Agency (SEPA) sets the bar higher than anyone we’ve come across. SEPA leads the way in ensuring waste to energy facilities are non-polluting.

In the same way auto-diesel engines are now super-clean, waste to energy technologies are operating that have sufficiently evolved to satisfy the ever-watchful SEPA. Benchmarks for this industry will continue to evolve so whichever solution a waste to energy proponent seeks; expect scalability, adaptability and low operating costs as key elements for the right decentralized or localized model.

Another key factor is capital cost which is available for deployments with the right waste feedstock, site, power take-off agreements, technology and team.

Like all truths, waste to energy is obvious when revealed. Prevent pollution, provide energy from stuff we throw away, create new jobs, out with the problems — in with solutions. Better yet: in with solutions proven elsewhere under harder scrutiny. It makes sense, in Canada we’re experts at learning and adapting from others.

Transporting a 9,000 lb. Dragon

Testimonial “I thank Eagle West for their extra care and courtesy; this was the first time I’ve had one of my pieces lifted and moved by a crane company and I will definitely use Eagle West again to transport other pieces and recommend them to everyone.”

— Kevin Stone, metal sculptor, Metal Animation Studio Inc.

T

he Pacific National Exhibition (PNE) in Vancouver, B.C., contracted Eagle West Industrial Moving to deliver an impressive piece of art. Weighing in at 9,000 lbs, with dimensions of 35’ x 14’ x 12’ the mirror polished stainless steel Chinese Imperial Water Dragon sculpture was successfully delivered to the PNE. This move sets a whole new standard for precious cargo.

The dragon was created by Canadian artist Kevin Stone from Metal Animation Studio Inc. located in Chilliwack. They specialize in largescale, one-of-a-kind, three-dimensional, stainless steel sculptures (www.metalanimation.com). Some of their past projects include a bald eagle with a 31’ wing span, hand crafted from mirror polished stainless steel.

Viewing their customers’ needs as their own, Eagle West Industrial Moving came prepared for the delicacy required for this move. Utilizing a 120 ton Liebherr All Terrain Crane, along with over 20,000 lbs of counterweight and two spreader bars, the dragon was carefully lifted onto the freight truck. Since the dragon was oversized and extremely reflective, a specially planned route with the correct permits was a must. Using this specific route, the freight truck and pilot car transported the dragon with extreme care to ensure this grand piece of cargo was delivered safely and undamaged.

After the safe and successful completion of this move, Eagle West Industrial Moving was contracted yet again. The responsibility this time was to transport the Chinese Imperial Water Dragon back to its home at the Metal Animation Studio. Dave Wittenberg, technical sales representative, Eagle West Cranes, stated that, “the job was challenging enough dealing with such a delicate piece of art, but since it was over height and over width, it made things a little more difficult. I am grateful for the expertise of all the Eagle West personnel involved.”

A short while after the dragon returned home, Eagle West was trusted a third time with this delicate piece of art. This move was to the dragon’s latest home, the River Rock Casino located in Richmond. This is where the dragon currently resides. Since this location is in a direct flight path of the Vancouver International Airport (YVR), Eagle West could not simply drive in a big crane to off-load it into position. Rather, they used a specialized industrial moving rail system to roll the dragon safely into place. Gary Klynsoon, manager-technical service, stated, “the rail system allows our Industrial Moving team to move equipment into places where there is limited crane accessibility, overhead obstructions, or to provide a more cost effective solution for our customers.” Utilizing Eagle West’s specialized industrial moving equipment and personal, the dragon was yet again moved into position safely and undamaged.

The Effects of “Pay When Paid” Clauses

By Ryan Sharp

...case law suggests that it is difficult for a contractor to enforce “pay when paid” clauses as more than a provision for the timing of payment...

A

subcontractor must be mindful of “pay when paid” clauses, or possibly assume the risk that it won’t get paid at all.

It is not uncommon to see subcontracts which include a clause indicating that the subcontractor will not be paid for its work until the contractor has been paid by the project owner. Clearly this can create additional risk for the subcontractor and consideration should be given to such a clause prior to committing to work for the contractor.

These “pay when paid” clauses have been considered several times by courts across the country.

The courts have unfortunately failed to reach a consensus regarding the interpretation of such a clause. There have been differing interpretations on this issue.

The first interpretation is that “pay when paid” clauses are simply provisions which speak to the timing of payments from the contractor to its subcontractors.

Favourably for subcontractors, this interpretation is more often the one followed. A leading case for this principle is Arnoldin Construction & Forms Ltd. v. Alta Surety Co. (1995). In this case, the subcontractor was partially paid for its work by the contractor, but the contractor refused to pay the balance owed as it had not been paid by the project owner (which had gone into receivership).

The court held that in order for a contractor to interpret a “pay when paid” clause to mean “pay only if paid,” the language must be very 36 construction business

March/April 2012

clear. Such a drastic interpretation can never be derived from obscure language.

There was no such clarity with respect to the clause in this case, so the subcontractor was entitled to payment under the bond that had been put in place by the contractor. The “pay when paid” clause at issue read: “The balance of the amount of the requisition as approved by the Contractor shall be due to the Subcontractor on or about one day after receipt by the Contractor of payment from the owners”.

Note that if a court finds the wording of the actual “pay when paid” clause to be ambiguous, it will likely rule in favour of the subcontractor over the contractor (as it is typically the contractor who has drafted the contract).

However, a different interpretation suggests that clear “pay when paid” clauses may result in the contractor having no obligation to pay its subcontractors at all if it has not been paid by the owner (i.e. the subcontractor being paid for its work is conditional on the contractor being paid by the owner). It is this possible interpretation that subcontractors should be particularly mindful of prior to signing an agreement with a contractor.

The most cited case interpreted this way is an Ontario Court of Appeal decision, Timbro Developments Ltd. v. Grimsby Diesel Motors Inc. (1988), heard by the Ontario Court of Appeal.

The court held that the relevant “pay when paid” clause in this case clearly specified the subcontractors’ legal entitlement to payment, and not

merely the timing of the payment, which “will be made not more than thirty (30) days after the submission date or ten (10) days after certification or when we have been paid by the owner, whichever is the later”.

Another, more recent, case considering a “pay when paid” clause is Voka Steel Inc. v. Edgecon Construction Inc. (2011). Although there were multiple issues in this case that the court had to consider, it was held that the “pay when paid” clause was clear enough for the contractor to only have to pay the subcontractor once they had been paid by the owner.

In summary, case law suggests that it is difficult for a contractor to enforce “pay when paid” clauses as more than a provision for the timing of payment (i.e. “pay only if paid”). However, in certain circumstances if the contract is sufficiently clear the subcontractor can be left without payment for their work as a result of the owner’s failure to pay the contractor. Ultimately, the proper interpretation of a “pay when paid” clause will depend on the specific language used in the contract.

It is important that subcontractors look out for “pay when paid” clauses in contracts and seek legal advice when necessary to ensure that the clause does not eliminate their entitlement to payment solely because the contractor has not been paid.

Where do Claims Come From?

By John Singleton

A

t some point of time in our early lives we asked “where do babies come from?” At some point of time in their careers, architects have asked “where do claims come from?” Although the source of each phenomenon is markedly different, each involves a certain incubation period, one producing the joy of life and the other the fear of financial death. So where do claims come from? Knowing the answer to that question should satisfy more than one’s curiosity: it should provide some insight into how to avoid perilous future paths in the construction industry.

There are of course many sources for claims against participants in the construction industry. Some arise due to human failings, others out of a lack of experience or qualifications and still others out of a failure to properly manage the design, field services or construction services being provided. It is statistically true that during the course of one’s career in this industry one is bound to make mistakes and thereby incur responsibility for construction claims because of a failure to meet the standard of care applicable to the service being provided. Once in a while there will be a failure to meet applicable codes and standards in a design or a failure to detect critical deficiencies in the field or poor workmanship on site.

That has been a source of claims ever since I started representing participants in this industry 43 years ago, and I expect it will always be a source of claims.

Along a similar vein, it has been, and I always expect will be the case that from time to time individuals with inappropriate experience are assigned design or construction tasks and mistakes are made simply because of their inexperience. We all know that assigning the right person, with the right skills, is a critical part of any business, and that is particularly so in the case of those involved in designing or constructing projects and inspecting the performance in the field. These two sources of claims can only be managed by better management of the consulting or construction operations through adopting effective risk management, quality assurance and quality control measures. Some may think that is stating the obvious, but my experience leads me to conclude that the obvious often goes unnoticed.

There is another source of claims which is probably not so obvious. It is this source which has proven to be the most significant source of claims brought against participants in the industry and it is this source which seems to regularly and continuously incubate problems.

It is the source out of which “products liability” is born. The usual scenario goes something like

this: a new “amazing” product or system is conceived, it is marketed to the construction industry, there is a rush by the industry to adopt the product and be “first on the scene”, the product finds its way into hundreds, if not thousands of projects around the world and, then, usually in a very short time period there is a mass product failure. Looking back, it then becomes clear that the product, its advertised features, the rush to adopt it and the decision to use it were all illconceived. Only on birth and in the early years of its use did it become clear that the incubation period had produced a financial nightmare for the industry.

Failures of products over the years have always been a source of claims against participants in the industry, including architects, and have resulted in many instances, in aggravated claims in the hundreds of millions of dollars. Indeed, in some instances, the product in question has placed some segments of the industry in financial peril and threatened its very future. Let me give you some examples.

Asbestos-containing products were introduced into the construction industry mid-way through the last century. The warning signs concerning the use of this mineral in building products began to surface in the mid to late 1950’s.

By the early 1970’s it was universally known that many of the products which incorporated certain types of asbestos created a substantial danger to human health and safety. This resulted not only in literally hundreds of thousands of claims arising out of the use of these products, but resulted in the bankruptcy and financial ruin of manufacturers and distributors of these products and the designers and trades who became involved in their use.

Fast forwarding to the last decade of the last century, there was a rush to the use of face-sealed design in the construction industry throughout North America. It presented a plethora of economic advantages to developers and there was a rush by the industry to adopt the face-sealed system, and its related products, in thousands of multi-family dwellings. Experience over the ensuing two decades has shown that the concept and the rush to adopt it was ill-conceived. It, too, resulted in the financial ruin of many participants in the industry, and threatened the financial well-being not only of the owners of these projects, but of the entire architectural profession in some jurisdictions.

Indeed, it threatened the financial stability of many insurers of participants in the construction industry.

There are multiple examples of other systemic product liability claims in the construction industry which have brought about equal, if not greater financial problems for many partici-

pants. Untold millions of dollars were expended or lost in removing or attempting to remove ureaformaldahyde from wall cavities where it had been sprayed as an insulating material because of a fear that off-gassing from the product created a danger to the health and safety of the building occupants. Horrendous fire losses were experienced in industrial facilities when it was determined that plastic coated cables used in electrical cable runs and cable trays acted like a dynamite fuse when subjected to a fire source, a product which had been inappropriately evaluated as fire retardant for this condition under a standard published by a well-known international testing agency. Engineers, builders and plant owners were threatened with financial ruin by these claims.

Poorly manufactured copper pipe, introduced into the construction industry at low cost, resulted in widespread failure of the piping and the attendant expense of re-piping low-rise and high-rise buildings. Similar problems were encountered with the use of plastic pipe used in manufacturing mobile homes.

The list goes on: window systems inappropriate for use in high-rise buildings, roofing membranes which deteriorated when exposed to sun light, building papers which deteriorated when exposed to incompatible building products containing resins and so on and so on and so on. All of these problems have been born out of product failures, out of ill-conceived and certified building products or systems. It is this source of claims, ill-conceived or poorly designed or poorly manufactured products which, in my experience, have been the major source of claims for the past four decades or so.

So what’s the point of all this? It is no more than a wake-up call. You should know each day you go into the office or into the field that you should be wary of and be keen to question the use of new products and technologies in an industry which has been plagued with claims arising out of decisions to quickly adopt new products without thinking through whether or not they are appropriate for the particular use in question. That is not to say by being alive to these issues there will not be any more product liability claims, for there will be many to keep the legal profession well endowed. But being aware of the source of claims and keeping your radar on to assist in detecting other incubating product liability problems, is an important, if not critical part of any effective risk management program for those involved in the construction industry.

Anti-Competitive Behaviour in Tendering

By Charles Bois and Owen Pawson

C

ompetition has always been fierce in the construction industry in Canada. There will always be too many contractors bidding for too few contracts. With the economy in a fragile state, the competition has become even fiercer — especially for lucrative government contracts.

As a result, competitors may be tempted to pursue any advantage they can to land a deal.

Conversely, owners conducting tenders must be more cautious in dealing with bidders, for fear of accidentally providing such an advantage. While some advantages may be legitimate opportunities for bidders, some conduct may be anti-competitive and therefore illegal.

This article will provide construction industry participants (owners, contractors, engineers) with a brief review of the legal traps to avoid in tendering. Falling into these traps could mean stiff penalties and the very real possibility of jail time.

The Law Competition in the construction industry is regulated by both legislation and the common law (i.e. judge-made law). The purpose of the laws is to maintain and encourage competition by prohibiting certain anti-competitive conduct.

Knowing what conduct constitutes anti-competitive behaviour is key in avoiding liability.

Legislation The federal Competition Act (the “Act”) is the primary piece of legislation applicable to the regulation of competition in the construction industry. The goal of the Act is to protect competition — not competitors — so its focus is on the public interest. It sets out various offences and corresponding penalties for certain anti-competitive behaviours, including both regulatory and criminal offences. Allegations of anti-competitive conduct are investigated by the Competition Bureau, who may refer the matter to the Competition Tribunal or lay criminal charges. The Com38 construction business

petition Tribunal adjudicates regulatory matters, while the courts deal with criminal offences and some specific regulatory matters.

Common Law A number of common law actions (or “torts”) have developed in the courts over the years to provide relief to victims of anti-competitive behaviour. These torts are available when legislation has not taken over. Unlike the Act, common law actions tend to focus on private interests, so these matters must be brought by the affected parties and are heard in the courts.

Identifying bid-rigging can be tricky. It is common for members of the industry to discuss contracts and prices outside the tendering process, which may result in similar bids. However, when the parties move from discussing who is bidding on which contracts to actually agreeing on whom will bid, not bid, or win which contracts, the line will be crossed into illegal bid-rigging.

A recent example of this line-crossing can be found in Quebec, where three companies pled guilty to bid-rigging in a hospital’s call for tenders. Prior to tendering and unknown to the hospital, the companies agreed on who would win the contract, and they worked together to manipulate their bids accordingly. The Quebec Superior Court ordered fines of $50,000 for one company and $25,000 for the other two. The Competition Bureau noted that if the recent amendments to the Act had been applicable, these companies would have faced much stiffer penalties, including jail time for the executives.

Intimidation Intimidation is a tort that occurs when one or more parties threaten another to get the intimidated person to do something against their wishes, such as withdrawing their bid. The threatened bidder would be entitled to damages from the intimidators.

Anti-Competitive Conduct

Other Anti-Competitive Conduct

The following is brief summary of the types of anti-competitive behaviours that can land bidders in hot water.

The Competition Bureau may review other anti-competitive behaviours that are not necessarily illegal. These include abuse of dominant position, exclusive dealing, refusal to deal, and market restriction. As always, the key is whether these activities unduly restrict competition.

Some other common law torts that may come into play with tenders are unlawful interference with economic interests, inducing breach of contract, and restraint of trade. This listing is meant to highlight some important legal issues, but it is not comprehensive. The best way to avoid anticompetitive conduct is to speak with legal counsel before acting.

Conspiracy Conspiracy is the most serious of all anti-competitive conduct, which is why it is both a criminal offence and a tort. It occurs when two or more competitors enter into an agreement to fix prices, allocate markets, or control supplies. The effect of the agreement must be to unduly lessen or prevent competition. The parties must have “market power” and purposively worked together to limit competition. Convictions for conspiracy are punishable with a fine of up to $25 million and/ or imprisonment of up to 14 years. The Act also allows the victims to seek damages for their loss.

Bid-Rigging Bid-rigging is perhaps the most notorious of all anti-competitive behaviours in the construction industry. It is another crime under the Act, where two or more bidders agree to either bid, withdraw a bid, or work together on a bid without the prior knowledge of the tenderer. Unlike conspiracy, the parties do not have to have market power. Companies or individuals convicted of bid-rigging are liable to a discretionary fine of any amount and/or up to 14 years in prison.

Conclusion Competition is vital for a healthy economy. If all goes to plan, competition provides owners with a wider range of options, drives down prices, and forces competitors to be more efficient.

The laws in place ensure competition remains fair, no matter the size of the players. Some conduct is clearly anti-competitive, but others may be a valid use of market position. When in doubt, seek legal advice.

Optimizing Performance

Extending the Service Life of Concrete Structures. By Neil A. Cumming

The concrete substructure of the Vancouver Convention Centre is exposed to sea water during each tidal cycle. Numerical modeling was used to predict time to corrosion, and to test various design alternatives to improve durability to achieve a 100 year design service life.

M

any people think of concrete as a durable, long-lasting material, however the experience of the past 40 years might suggest otherwise. Governments in Canada, the U.S. and Europe have spent billions of dollars repairing and restoring aging structures that have not met their service life expectations, and engineers have warned that this is only the beginning. Indeed, when many of these structures were designed and built, service life was not a significant consideration. The result is that bridges, marine structures, dams, industrial plants, and many other structures built in the early to midtwentieth century began to deteriorate much earlier than expected, and we are now paying the price.

Having learned the lesson to some degree, owners and designers are now paying more attention to service life expectations during the design phase of projects. Service life expectations are being stated in defined terms, typically of 75 to 100 years. Many specifications and contracts have a definition of what “service life” is and how it will be measured.

Designers are trying to assess the effect of various design options on service life and are making design decisions to optimize service life performance.

The aspect that has perhaps not been fully recognized is the cooperative, fully-integrated approach of all the players in the design, construction and maintenance process that is necessary to actually achieve the optimum balance between service life, functional performance, initial cost and maintenance cost.

Managing Expectations — What is Service Life?

Service life is often defined as the period of time in which a structure performs its function without unforeseen or extraordinary maintenance or repair. Therefore, when considering service life, it is critical to define the level of maintenance the owner is prepared to accept. This is important when considering the trade-offs between initial cost and future maintenance cost. A typical example of this is a decision to use corrosion-

resistant rebar, which is now available in various forms. The increase in initial cost is significant, which is problematic for many owners who face budget restrictions. On the other hand, the savings in maintenance costs for bridge decks or marine structures can be substantial. Hence, the expectations of owners with respect to maintenance responsibilities must be established and the life cycle cost/benefit analysis of these design options must be given appropriate attention at the design stage of a project.

Predicting Service Life Service life of a concrete structure depends on many variables, some of which are environmental and thus beyond the control of the designers and owners. So when one sets out to design such a structure, how can service life be predicted? Fortunately there are design tools becoming available to assist designers in this task. Numerical modeling is now used to predict time to corrosion of rebar, which is the primary mechanism of concrete deterioration. These models allow various design options to be tested under various environmental conditions, and rational decisions can be made to improve durability at reasonable cost. In another mode, the time to first repair can be estimated for various scenarios, allowing a comparison of initial and maintenance costs.

More sophisticated models are under development that will allow similar analyses to be made of other forms of concrete deterioration such as alkali-aggregate reactivity and sulfate attack. There is abundant activity among researchers and practitioners to develop and improve these modeling techniques, and they are becoming adopted into common design practice. Numerical modeling has been used locally to predict time to corrosion for the Vancouver Convention Center Expansion, bridges on the Sea to Sky and Port Mann Highway 1 projects, and other structures.

Achieving Service Life We have reached a stage where 100 year service life of our concrete structures can be achieved with rela-

tive ease on paper. But achieving it in the real world requires an integrated approach. Modern design standards now address the service life objectives and have been adopted into building codes and specifications. Designers are more aware and are using the tools at their disposal to improve durability and reduce maintenance requirements. Materials suppliers are developing corrosion resistant rebar, supplementary cementing materials to improve concrete properties, and admixtures to stem other deterioration processes. Owners are more cognizant of the importance of maintenance and the trade-offs they can make between initial cost and maintenance costs. And contractors have developed quality control procedures to improve construction practices (curing, cover thickness, crack control) that will improve durability. The critical point is that all the actors have a role to play in achieving these extended service life expectations.

Finally, it is interesting to think about what the concrete construction world will be like 75 years from now, when today’s structures will be nearing the end of their intended service lives.

When we think of this in relation to the advances in concrete technology that have occurred in the last 75 years it is clear that we will be relying on technology that has yet to be developed to keep these structures in service even longer.

Neil A. Cumming, FACI, P.Eng., is executive vice president of Levelton Consultants Ltd.

Many structures that have already provided decades of service are being rehabilitated to provide up to 75 years of additional service.

Thinking outside the envelope A Net Zero Precast Concrete Home By Dennis Lattimore

D

ubbed a learning vehicle from the very start, construction of a net zero precast concrete home in Edmonton is a unique project that allows partners, Lafarge and Stantec, to better understand the true benefits of the integrative design process (IDP) in driving sustainable, energy efficient dwellings.

Learning is the goal for the industry partners, but the immediate beneficiaries will be two Habitat for Humanity (HFHE) families in Edmonton. The duplex’s innovative and integrative design, coupled with sustainable materials, will help create a very energy-efficient precast concrete home. This means that HFHE’s goal of providing a “hand up” to two hard-working families will be enhanced by lowering their energy bills — ideally to zero over the course of a year.

The Habitat families pay an interest-free mortgage that is amortized to 25 percent of their income; one the reasons why Habitat homes are affordable. The mortgage payments are reinvested into building more Habitat homes giving the Habitat program continuity. Families also contribute 500 hours of “sweat equity” on other Habitat projects as their down payment for the home.

This project is the first of its kind in Canada.

We are proud to support communities where they operate and to be involved in a solution which addresses sustainability’s triple bottom line — environmental, economic and social. Lafarge, Stantec, and HFHE are excited to pioneer a solution with the potential to reduce negative impacts of communities in the future. This project will help the team validate hypothesizes with respect to design, methods and materials driving better informed choices.

Canada Green Building Council’s Alberta chapter is also deeply committed to the project; donating the LEED for Homes certification reviewer and energy modeling to assist the project to achieve certification. The building is identical in size, orientation, and footprint to previous HFH duplexes in Edmonton built using traditional framing and construction methods. This allows the project team to measure and verify the home’s energy performance over the next five years and compare the results with their traditionally built twins. The duplex has the potential to achieve LEED Platinum certification.

From the beginning, the project was intended to be sustainable, with net zero becoming an achievable possibility after the envelope alone was able to achieve an EnerGuide 86 rating.

Dow’s contribution of high R-value insulation for the building envelope provided a real boost.

The net zero house project has been developed through an integrative and collaborative design process linking design, construction methods, and materials to provide an energy efficient home creating as much energy as it consumes on an annual basis. The extensive and multi-discipline developmental/design work that took place early in the conceptual stage paid dividends towards the goal of attaining net zero. The interface of 3D BIM modeling through the entire IDP helped solve constructability challenges and provide a better sustainable building solution. Other partners that make the IDP possible are Kassian Dyck & Associates, Vital Engineering, EcoAmmo and EcoSynergy.

Some of the knowledge gained from this unique project has been the design and development of high performance insulated precast panels addressing multiple building needs. These

panels provide structural support, architectural exterior finish, insulation and vapour barrier as well as interior wall finishes — all accomplished with the same precast element. Moreover, the interface of different trades and material suppliers has allowed for a better understanding of the challenges and the cooperation that is required to maximize the benefits of combining multiple green building concepts and solutions.

Construction on the new duplex will commence in June with families receiving their keys in September. In this case, the building envelope consisting of precast panels complete with windows will be installed in only several days with a small crane and crew. When compared to typical building methods, precast concrete brings the sustainable attributes of waste reduction, reduced construction time, reduction of safety risks, and innovation in materials.

The precast components for the structure are manufactured at the Lafarge precast plant in Edmonton where windows, exterior finish, electrical and mechanical openings are installed in controlled conditions before being transported to the Riverdale community site for assembly.

A hybrid geothermal / solar thermal mechanical system will provide domestic hot water and heat for the building. During the winter months the building will draw from the power grid but during the summer a solar PV array will provide the building with its electrical needs as well as exporting surpluses back to the grid.

This project exemplifies the use of a learning vehicle, allowing the partners to make informed choices to address future construction sustainability needs.

Dennis Lattimore is vice president of marketing for Lafarge Western Canada.

Anticipated benefits using precast concrete • High energy efficiency building envelope: R44 Walls & Basement Slab, R88 roof • Construction site waste reduction. Off site production • Enhanced Durability — Longevity • Reusability benefits (cradle to cradle) • Fire and sound resistance • Long span to depth ratio. Less structural material • Regional materials • Lower life cycle cost • Recycle Content (Fly Ash/Silica Fume) • Innovative design: use BIM to integrate design, manufacturing, construction

ARMCA Celebrates 50 years

CB spoke with Laura Reschke, executive director of the Alberta Ready-Mixed Concrete Association, about the association’s golden anniversary and what the future holds.

L-R: Laura Reschke, executive director; Ed Kalis — director of technical services and training; Cheryl Grisé — administrative assistant.

CB: What does ARMCA’s 50th anniversary mean to you and members?

LR: It’s a year to celebrate the accomplishments of the ARMCA, and to recognize the people responsible for the longevity of the association. ARMCA has been a strong voice for the members on all industry related issues. The retained membership is a testament to the strength of the association in bringing industry related businesses together for survival in an unpredictable marketplace.

CB: What is the association doing to mark the occasion?

LR: Our major celebration will take place in May at our Annual General Meeting and Convention. We hope to see many of our active and retired members participate in two days of fun filled activities including golf, special evening entertainment, and the President’s Banquet where we’ll acknowledge those who have graciously contributed their time and expertise for the ongoing success of the association. We offer a children’s program as well as a spousal program, and everything is centered on ARMCA’s 50th birthday. We will also introduce ARMCA’s new look with an updated logo and website to be launched during this event.

CB: Why is the ARMCA an important association?

LR: Invaluable training and certification is provided to members and non-members through the ARMCA. The ARMCA is the voice of the industry for governmental issues. Since 1962, the ARMCA has evolved to become the readymixed industry’s principal representative for the growth and protection of the ready-mixed industry in Alberta with respect to regulation, development, and production operations. Our association requires the participation and position of all sectors of the industry that collectively make up the Alberta ready-mixed market.

CB: What has been key to the association’s success?

LR: ARMCA’s successes have been accomplished primarily through the volunteer efforts of technical, supervisory, and management personnel of many industry related companies that staff various ARMCA committees and subcommittees related to government relations and association management. It is the commitment of our members that help to shape our industry.

CB: What have been some important achievements?

LR: Due to a need for consumer protection on the quality of concrete being supplied, ARMCA created a specification for a concrete mix, “Duramix®”, a registered trademark of the association.

Duramix® is a product that meets all minimum standards of the national building code and is recommended for exterior applications such as driveways, concrete pavements, and parking lots, and is only available through ARMCA members.

The ARMCA developed an environmental management practices document for Alberta.

The association also developed a plant certification program for members. We provide ongoing training in concrete technology, and offer industry certification programs such as, Field Testing, Driver Certification, Plant Certification, and Pump Operators Safety Training and Certification.

The ARMCA staff and members provide representation on many committees that have influenced codes and standards affecting our industry.

CB: What are some initiatives the association is working on now?

LR: We continue to work with partners in the cement and concrete industry to promote concrete as a durable and sustainable product that will improve the overall environmental footprint.

In our promotion of concrete pavements, we are working with the provincial government on the utilization of concrete intersections where other materials have failed. We strive to create consumer awareness of the long term advantages of concrete both in sustainability and in long term fiscal

responsibility. We are developing documents to outline proper procedures for placing and finishing residential concrete and emphasizing the need for certified contractors. We help to educate consumers and the construction industry on understanding concrete, through documentation and information provided on our website; www.armca.net. Promotion of ICF construction (Insulated Concrete Forms) for substantial increased energy efficiency is another undertaking.

CB: What are some major issues facing the industry?

LR: Many people are not aware that concrete is the most consumed product globally, next to water. A major issue we are faced with is a skilled labour shortage in all aspects of our industry.

We are also challenged with attracting people to work in the concrete industry when there are so many choices due to the strong Alberta economy.

Also, the perception that concrete is not as cost effective as other paving materials, when this is not the case if one looks at the entire life cycle cost of concrete versus other paving materials.

CB: What is the outlook for the industry?

LR: The industry continues to develop new sustainable products through research and development. Very strong growth is anticipated.

The market will continue to grow to where the shortage of labour may not allow us to meet industry demands.

CB: How big is the association today? And what types of work are members responsible for?

LR: Our membership represents approximately 93 per cent of all ready-mixed producers in Alberta, many associate companies supplying the readymixed industry with a product or service, as well as affiliate members connected with the ready-mixed concrete business as a sub-trade or user of concrete such as cribbers, placers, finishers and pumpers, totalling approximately 257 members. Our members represent 98 per cent of the concrete volumes produced in the province of Alberta.

CB: What does the future hold for the association?

LR: ARMCA will continue to build on its success in establishing effective, mutually beneficial relationships with members, communities and the construction industry.

What Would Nature Do?

By Veronica Gilles and Anna Buchan

O

ften guilty of seeking the latest “cool” factor, architects are discovering that Biomimicry can be more than a sexy keyword on their web sites.

Emulating nature’s time-tested ideas to solve problems isn’t new. Five centuries ago Leonardo da Vinci looked to nature for the design of a flying machine: “Remember that your flying machine must imitate no other than the bat, because the web is what by its union gives the armour, or strength to the wings.”

Still, architects have been slow to catch on.

In fact, it was two biologists — Janine Benyus and Dr. Dayna Baumeister — who established a company to use Biomimicry to help designers, engineers, architects and business leaders develop sustainable products and processes. In 1998 they established the Biomimicry Group, and published the seminal book Biomimicry: Innovation Inspired by Nature. Their phone soon started ringing, with organizations like General Electric, NASA, Boeing, and Nike calling to find out how Biomimicry might help ”green” their products, policies and processes.

44 construction business

March/April 2012

What Biomimicry is Not A common misunderstanding of Biomimicry is that it refers to how nature can be used by designers simply to inspire the form of a building, a chair or even a hat. Biomimicry is not a biomorphic design tool; it is a biology-related science that differs from other bio-approaches by consulting organisms and ecosystems and applying the underlying design principles to innovation. It is a conscious emulation of nature’s function that goes well beyond form or metaphor. The design process stretches conventional notions of design integration by requiring the participation of a biologist to understand fully nature’s functions.

What Biomimicry Is Practitioners who incorporate the principles of Biomimicry essentially begin with one simple question: What would nature do?

Using biomimicry as a tool for sustainability requires a thought process that extends beyond the typical design process. We must ask not what we want to design, but must identify what we want the design to do. Then we ask nature what

it would do. How does the ecosystem capture energy, manage shear, attach temporarily, or clean water? Once we discover models in the natural world, we ask how we might mimic these principles and strategies, and emulate them. Finally, it is important to evaluate our designs, asking if they are really following the principles that nature uses to create conditions conducive to life.

Biomimicry in Architecture Although LEED has become the accepted standard for sustainable buildings in British Columbia, a world full of LEED Platinum buildings could still destroy the planet. Adopting a starting mantra of ‘no harm done’ could prove to be more realistic as the sustainability movement inches towards regenerative design ideas.

…the opportunities for applying the Biomimicry methodology to architectural design are unlimited. of a particular land. It encourages locally-attuned strategies that match local operating conditions and ecologies.

The process is rigorous, and a biologist is always part of the design team. The ecological and engineering challenges are first defined, followed by the identification of “champion adaptors” — the ingenious creatures and plants of a particular place that can provide guidance for locally-attuned design strategies. Design solutions are then tested against the “Life’s Principles” checklist and a measurable and rigorous Environmental Performance Standards. In this way, the actual function of a project, process or even organizational structure is informed at every step.

Who will inspire you?

HOK, which has an office in Vancouver, is contributing to this thought leadership by forging an exclusive alliance with the Biomimicry Group to integrate nature’s innovations in the planning and design of buildings, communities and cities worldwide. HOK chairman Bill Valentine FAIA, LEED AP says working with biologist Janine Benyus has been pivotal for HOK. ”We were immersed in a sea of information, strategies, science and insight, and left with a strong commitment for a far wider discovery and education of these ideas across the firm.”

To date, the HOK / Biomimicry Group alliance has eight planning and design projects around the

world. “Not only should this help us significantly reduce the environmental impact of our projects,” says HOK sustainable design director Mary Ann Lazarus FAIA LEED AP BD+C, “but it also has the potential to help define a whole new sustainable standard for our profession.”

The Genius of Place “Genius of Place” is a component of the Biomimicry Group’s design methodology for sitespecific challenges. It honours local wisdom and actively looks and listens for ways that local geniuses manage water, build soil, deal with changes in climate, and address other challenges

Clearly, the opportunities for applying the Biomimicry methodology to architectural design are unlimited. But it demands an explosion of conventional thinking. The method is clear: identify the challenges and ask, “What nature would do?”

Engage a biologist to help discover an appropriate model (the champion adapter), and understand its principles and strategies. Then analyze how the champion adapter functions and apply that functioning to your own design challenges.

Too often, architects are quick to come up with clever formal solutions — the familiar “sketch on a paper napkin” trick — followed, sometimes years later, by its rationalization.

Biomimicry offers architects the potential for creating sustainable and efficient buildings, systems and environments that follow the principles tested by nature over the last 3.8 billion years. To take advantage of this approach, however, requires us to quiet our cleverness and listen to nature for the true answers. As Benyus states: “…when the city and forest are functionally indistinguishable, that’s when we’ll really be at home on this planet.”

Flint comes to the post after more than two decades of leadership in the Canadian Armed Forces where he was most recently Commanding Officer of the Mission Transition Task Force Engineer Regiment in Kandahar, Afghanistan where he led the engineering effort for the orderly withdrawal and relocation of Canadian equipment, supplies and personnel.

The association changed its name in March (dropping a G). The new name reflects the change to licensing Professional Geoscientists (P.Geo.) instead of Professional Geologists (P.Geol.) and Professional Geophysicists (P.Geoph.). Alberta was the last jurisdiction in Canada to separately license Professional Geologists and Professional Geophysicists.

Unique Tower Proposal A unique 49-storey tower is being proposed at the north end of the Granville Street Bridge. The tower, at the corner of Howe Street and Beach Avenue, starts as a triangle at the base but twists into a rectangle higher up above the bridge. The $200 million mixed use project is by developer Westbank Projects Corp. and Danish architect Bjarke Ingels. The residential tower will have a nine storey podium which will include market rental housing, commercial uses and a childcare facility.

ESC Certification To promote corporate sustainability strategies in the construction sector, VRCA has launched the Excellence in Sustainable Construction (ESC) Certification Program, one of the first of its kind in North America to certify a construction company, rather than a construction project. The aim of the association-developed program is to encourage the three pillars of sustainability within construction companies, finding synergies between profits, protecting the environment and supporting communities.

A pilot version of the program was initiated in July 2011, which resulted in four successful applicants: Scott Construction Group, Flynn Canada Ltd., Gerry Enns Contracting Ltd. and Lark Group. The four companies received their ESC certifications on February 23, 2012 at a launch and recognition event held at Van Dusen Botanical Garden.

RAINDROP TO GO WHERE IT DOESN’T BELONG

All roofing guarantees are not created equal. Case in point: a non-prorated RoofStar Guarantee by RGC is good for five- or ten-years and completely covers all labour and materials. RoofStar is also the only one that includes a comprehensive inspection schedule overseen by independent, third-party inspectors who monitor the installation process and follow-up inspections at pre-determined intervals.

All of which is comforting. Because the only thing more determined than a raindrop is our commitment to make sure none of them ever go where they don’t belong.
