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.
As an emergency measure, a temporary heating plant was quickly constructed near the Supreme Court of Canada. PCL’s David Coyle was part of the leadership team that developed the conceptual layout, schedule and planning as well as site supervision during the construction and commissioning phases of the project. Utilizing his industry contacts, Coyle found all major pieces of equipment and sourced qualified mechanical and electrical contractors capable of performing the emergency repairs under an exceptionally stressful time and difficult site constraints. With teams working 24/7, the temporary facility was successfully commissioned within 37 days.

OBJ launches the 2026 Executive Report on Cornwall

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.
