C O M P A N Y W E B S I T E P A G E I D # R esidents and tenants likely are to be stampeding soon to One-Six, a new five-story, 71,763-square-foot building that recent- ly joined the skyline of Calgary, Alberta. One-Six features 103 units on four residential levels and one level of ground-floor retail. The building's comfort system and domestic hot- and cold-water supply features extensive use of Aquatherm Blue Pipe SDR 17.6 and Aquatherm Green Pipe SDR 11. The comfort system is comprised of a chiller and six boilers. Nu-Mun Contracting Ltd. rec- ommended and ultimately installed Aquatherm polypropylene random pipe for all the system's mains and risers, in- corporating over 750 feet of 6-inch Blue Pipe SDR 17.6. Nu-Mun Vice President David Muncaster explained that the firm has been using Aquatherm for a decade and the piping systems offer numerous advantages compared with steel pipe, including outstanding durability with a service life of 60+ years, low operating and maintenance costs for the owner and a low likelihood of being targeted by thieves at the jobsite. In addition, a heat fusion installation process does not require a flame watch like welding does. Nu-Mun considered a few options when specifying the project's piping systems. In the end, Muncaster said the cost of steel fittings and the longer cure time and difficulties of gluing and prim- ing other plastic pipe systems in cold weather ruled those options out. RIGHT TOOLS FOR THE JOB Through the years, Nu-Mun has had hundreds of employees complete the Aquatherm factory-certified heat fusion training programs and all its plumbers are certified for one or more of Aqua- therm's fusion techniques, (including socket, butt and electrofusion). For the One-Six project, two install- ers spent about 10 days fabricating fit- tings in a 750-square-foot shop to create custom-built rolling vertical offsets to work around the building's structural components. The skill of Nu-Mun's team and its years of experience with Aquatherm pipe were evident through- out the project. "We did all prefab and custom piping in house at our shop, vastly speeding up the onsite installa- tion time," Muncaster said. ACROSS AND UP The Aquatherm Blue Pipe SDR 17.6 travels down the building's fifth floor hallway, just over half the length of the building, before transitioning into a vertical riser. The pipe wraps 270 degrees around a stairwell then travels down the backside of the stairwell be- fore entering a mechanical room in the parking garage. The mechanical room incorporates custom pre-built 90 degree elbows, offsets, tees and take-offs. Other key components of the system include six Weil-McLain Evergreen 399 boilers, a Baltimore Aircoil chiller, ClimateMas- ter heat pumps, Thermotek makeup air units and Grundfos pumps. Muncaster explained that Nu-Mun has gained extensive experience with the pipe over many years, in projects that have included numerous commer- cial four-story walk-ups, custom homes and 15 condominium buildings ranging in size from 10 to 160 suites. "We've been using Aquatherm pipe for more than a decade, so we know how it can help us solve very challenging situations," Muncaster said. HALVING LABOR Per Muncaster, the ability to custom fabricate the piping offsite at Nu-Mun's shop presented huge labor and cost savings over steel pipe. He estimated that labor costs on the One-Six project would have doubled if the company had tried to use steel. "There were some really tricky custom fittings we could only make in Aquatherm, because we knew it was light enough that our crews could then get it in place," Muncaster said. Colin Middleton, principal, Allen Wasnea Engineering, Edmonton, Alber- ta, said his firm completed the project work on a very tight timeline thanks in large part to Nu-Mun's experience with the Aquatherm pipe and the product's versatility. "David Muncaster was very instru- mental in helping us size the system, be- cause being all metric means the sizing is totally different than standard pipe sizes," Middleton said. "He helped us greatly with his knowledge of what the Aquatherm pipe was capable of based on his extensive experience with it." The building, which was completed in September 2017, is being rented out to occupants and tenants, and Muncaster is confident that although they may never be aware of the role Aquatherm and Nu-Mun Contracting played in their comfort, they will be happy living or working in the One-Six. "This project turned out really well. I'm very happy with how it looks, the overall quality and how it works. Aqua- therm has been a fantastic product with nearly zero issues in the 10 years we have used it," he concluded.
