Exploring Opportunities

ell, spring has sprung. Or at least we hope it has by the time this magazine is published, which truthfully, is almost summer. At the time of writing this, the air is still
chilly and the skies are opening with torrential rainfall that threatens flooding in the normally dry Okanagan. This spring is the first with a new category of membership at MCABC: the non-voting affiliate member. There are now two options for affiliates. The first is full membership, with dues at half the contractor rate (a sliding scale) and includes voting status on all MCABC/MCAC business. The second non-voting status has flat-rate dues equal to those of associate members. A few existing members have chosen to change over to this new membership category and we have attracted some new members. As word continues to spread about this new lower-priced option, we hope to expand our membership even more. Last year, we saw significant progress in the partnership with the Electrical Contractors Association to bring the onerous contract clauses to life. These documents will help contractors minimize legal risk in their contracts with clients. We plan to put these proprietary documents online and make them accessible to members but have been delayed with both technical issues and scheduling problems. However, we promise a solution is close and we will be announcing how to access these valuable documents soon. Trades harmonization has recently become an issue for our industry when it was discovered that the ITA had created a template for a gasfitter’s trade and plans to eliminate B-fitter license training in the plumbing curriculum. The purpose of this is to ‘harmonize’ the training of trades across Canada, to which (ITA argued) B.C. was committed. Many of our members remain unconvinced this is the best way to train our apprentices and a letter arguing against this initiative has been sent to MCAC to present to the national apprenticeship directors. MCABC has followed up on our president’s initiative to explore opportunities to attract more service contractors into the association by engaging with UA Local 516 to develop a unique Service Contractor Services and Education program. It is clear that service contractors

want much of what MCABC has to offer, but they are less clear about whether it is MCABC that should deliver those services. We remain in discussion with 516 on how to move forward with this initiative. I would also like to address the recent B.C. provincial election but

as of press time, the final results are still a little unclear. Whatever the politics, we will continue to pursue Prompt Payment legislation. Through an email campaign we ran prior to the election, we now know where many of the former candidates, now elected MLAs, stand on the issue and we intend to hold them to their word. Positive progress has been made federally with the prompt payment bill having recently passed the senate and we intend to push for similar progress provincially. I hope all our members continue to enjoy success in the mechanical contracting industry in the coming months with construction still going strong and many large projects on the go. While our provincial government leadership may currently present some uncertainty, the B.C. economy remains strong and we continue to count our blessings.

The new View Royal Surgical Centre in Victoria is a 17,000-square-foot facility that occupies one and a half levels within a fivestorey office building. PML completed the base building in early 2016 before mobilizing again in October 2016 for the addition of the centre. “This wasn’t a purpose-built building for a surgical centre — it’s an office building,” says Edwin Wong, project manager at PML. “In addition, this was a fast-paced project — an accelerated schedule to put a hospital into a non-purpose-built building. That’s been our biggest challenge.” Completed in April 2017, View Royal is the first private surgical centre in Victoria, providing outpatient surgical services. It is expected to perform 2,500 to 2,750 surgeries annually. Procedures will include carpal-tunnel surgery, hernia repairs, colonoscopy and other endoscopy procedures. It is part of Island Health’s larger strategy to reduce surgical wait times and improve care. Located in Eagle Creek Village and next to

“The air handling units are huge — 40 feet long — and they had to be craned up onto the roof and they sit on structural steel supports that are bolted to the frame of the building,” notes Wong. “There is a diesel generator in the parkade as well.” A 270-ton mobile crane was necessary to lift all the large equipment onto the roof. “Anything that didn’t fit into the elevator had to be craned onto the roof. That was a challenge,” he says, noting they had to notify Victoria General Hospital whenever they were using the crane. PML also had to run new lines to serve the centre. It does not share domestic hot water with the base building. It requires its own electric and gas domestic hot water heaters. “We had to run a new three-inch domestic water main up from the parkade through an existing building. Finding a path and space was challenging,” says Wong. Once all the new equipment was added, “the natural gas had to be boosted from a two-pound system to a fivepound system, so that meant new meters — new regulators. A lot of things had to be changed out.” An army of trades was on site to meet the aggressive schedule. Wong estimates at

Greg Chapman likes to solve problems. His knack for problem solving has led to a successful 33-year career in mechanical contracting. “I like the challenge of going in... where no one can figure out why it doesn’t work,” says the 52-year-old owner of Chapman Burner & Heating Service Ltd. “I understand things quickly. I grasp the concept and then we try to make the square peg fit in the round hole.” Born and raised in Vancouver, Chapman had an early interest in electricity and worked parttime as an electrician through high school. After graduating in 1983, he was offered a part-time job in the heating industry. “My first day was 16 hours and I’ve never looked back,” he recalls. “Back then, you didn’t have to get a plumbing license to become a gas fitter so I started working on oil burners. When BC Hydro had the oil-to-gas rebate, we would do one or two appliances a day converting them from oil to gas.” He would go on to work for different companies including Armstrong Pumps, Clear Brooks and was a part owner of Spears Sales & Service. In June 1999, he struck out on his own and founded Chapman Burner & Heating Service Ltd.

equipment — electric boilers, heat pumps — has so many problems,” he says, explaining often people select cheaper new products that are not robust and fail within several years. “It can be frustrating dealing with substandard equipment. You really need somebody who understands the whole system to be able to troubleshoot and offer solutions that won’t keep coming back to haunt people.” Chapman also sees issues with some new products such as plastic compression fittings. “We see a lot of failure of piping and venting systems or equipment itself. We are primarily still welding steel pipe so we do feel traditional methodologies have not let us down.” Another trend in the industry is the growing demand for integration of building systems.

On the condenser side, we use a pump and three-way mixing valve to recirculate the leaving condenser water back into the inlet condenser connection of the machines. As this condenser water circulates around and around, it continually warms up, until it reaches about 43°C, at which point we crack the three-way valve and discharge the warm condenser water into the hydronic heating loop. Once the recovered heat is into the hydronic loop, we can use it to provide heating at the air handlers, at the reheat coils or to preheat domestic hot water.

alk onto any construction site and you’re bound to encounter silica dust, well recognized as a potential
occupational disease hazard. Until recently, controlling exposures to the substance had been kind of hit and miss: contractors knew it was a problem but weren’t always sure when, how, or even if they had to deal with it. Now, thanks to generous support from the BC Construction Safety Alliance’s (BCCSA) Research Development and Opportunity Fund, companies have access to a free, made-in-B.C. computerized solution that can be used to quickly and easily assess the risks and identify precautions required to protect workers. Developed by the BCCSA in conjunction with WorkSafeBC and researchers from the University of British Columbia, the first-of-its-kind webbased Silica Control Tool (ST) brings into one place existing monitoring data gathered from an array of industry surveys and studies on worker exposures to silica dust.

MCABC AND ALBERTA TAKE VICTORIA BY STORM The 2017 conference was a reunion of sorts as the MCAs of British Columbia and Alberta joined forces to host A Royal Island Experience in Victoria, B.C. It had been nearly 20 years since a joint conference was held and it was great to meet up with colleagues from our neighbouring province and make some new connections! The conference was held at Westin’s Bear Mountain Resort and Spa, taking advantage of amenities like the fabulous Nicklaus-designed Valley Golf Course and luxurious Santé Spa. The three-day event saw everything from gorgeous sunshine for our outdoor welcome reception (phew!) and hail for the golf tournament. Activities included a walking tour of Victoria with lunch in Chinatown, zip lining through the forest canopy of Sooke and a cooking lesson and wine pairing with Westin Bear Mountain’s executive chef. New this year was a complimentary spa appointment for each delegate with their choice of a relaxation massage, pedicure or manicure. The pub crawl was revived at the request of our Alberta colleagues with much socializing at some of Victoria’s finest public establishments. B.C.’s associate members held an event to remember with the theme of Treasure Island. Why are pirates the best? They just aaargh! Oh yes, we also held some meetings, including our annual general meeting.
