General Contracting

In the last few years, Birnam has been incorporating a more solid focus into the General Contracting industry, specializing in strong Project Management. Our General Contracting Division works with mechanical systems, process works, water and wastewater, and general infrastructure projects. These include water treatment facilities, pump stations, process piping, retrofits and rebuilds, as well as state of the art lagoon aeration systems, new buildings and a variety of structures.

In the last couple of years, this division has expanded under the guidance of Phil Coeck due to his extensive expertise. We complete our jobs start to finish, with quality and integrity. This increased focus on our General Contracting Division has helped us target the Municipal ICI sector.

In 2016, Birnam began work at the Bright’s Grove Lagoon, installing a new sewage treatment facility, which treats 3500 cubic metres a day. Using state of the art technology, and an existing lagoon, our GC division created a full-scale treatment plant, in record time. This project was time sensitive with a variety of environmental considerations, and required the existing plant remain functioning throughout the project to ensure the upkeep of wastewater processing demands for the City of Sarnia. This 13-million-dollar venture included upgrading 2 lagoon cells with new diffused aeration systems and chambers, and replacing existing sand filters with the new Submerged Aqueous Growth Reactor (SAGR) system consisting of 4 cells. The project required the creation of a new SAGR effluent Pumping Station, a new tertiary filter building, multiple upgrades to the existing site and facility, as well as the decommissioning and environmental remediation of a lagoon cell.
