Envirotech delivered the Graham Sutherland Energy Centre upgrade over the university’s summer break, acting as Main Contractor for this complex plantroom replacement.

The project included the installation of four boilers, a chiller, and a CHP unit with a total heating load of 4.5MW. A new rooftop plant area was created for chillers and heat dumps, along with a packaged booster room and a new compressor room serving the building’s compressed air circuits. The system was converted from open-vented to sealed, and all DHWS services remained live throughout via temporary plant.

Working within a live university environment, challenges included coordinating works across a main student thoroughfare and managing extensive asbestos removal in the chimney structure. A key tenant required uninterrupted access throughout the project, including during crane lifts—managed through regular coordination meetings.

Off-site prefabrication using Revit and pre-assembled temporary headers allowed for fast, efficient installation and minimal disruption to university operations.
