In 2009, a tragic explosion badly damaged the Cliff Central Heating and Cooling Plant, crippling the ability of the facility to heat approximately 50 buildings in downtown Ottawa.

With teams working 24/7, the temporary facility was successfully commissioned within 37 days.

Throughout his career, Coyle has had a hand in the building systems of many of the city’s most recognizable buildings, including the Canadian War Museum, Constitution Square Tower Three and West Block.
He’s the primary point of contact for the majority of PCL’s relationships with local mechanical and electrical subcontractors and is often requested by name among clients seeking to do repeat business with PCL.
