Project Details

$75m upgrade for the College of Engineering and Computer Sciences

Awarded the mechanical services contract for the project by Hindmarsh Construction, Benmax completed a major refurbishment of the Birch Building (Building 35) located at the Australian National University in Acton, Canberra.

Constructed in 1967, the 11,148 sqm heritage listed building previously housed the Research School of Chemistry but is now home to the College of Engineering and Computer Science with contemporary teaching spaces, MakerSpace learning environments and PC1/PC2 Certified research laboratories.

In line with strict requirements to maintain the buildings heritage features, including the unique precast façade, atrium stair and coffered floor slabs, the structure was stripped back to slab, columns and external walls with only the façade remaining.

Structures within the building were then strengthened to accommodate modern day building services and allow for an additional storey to be added for the large plant room. Works included reengineered load paths and footings, heavy steel bracing walls, and a new reinforced roof structure capable of supporting increased loads, including more than 35 x AHUs and 49 x fans.

To meet the needs of the client the entire project team was required to work to a tight construction program. To support this, Benmax incorporated the use of prefabricated and preassembled HVAC equipment into the build. This innovative construction method supported higher levels of productivity and enabled improved delivery time frames, while also supporting the highest standards of quality control and on-site safety of workers.

Benmax achieved practical completion on the project in August 2021.

“10/10. An excellent contractor to work with who can push a programme when its needed.”
