Engineering in Colac and the Colac Otway District

For Irwin Consulting Engineers, a Geelong and Warrnambool based practice, Colac sits right between the two bases. It is one of the eight service areas, and clients in Colac and the surrounding district work with the principal directly.

Colac enquiries range from town blocks to rural properties: new homes, extensions, sheds and outbuildings, and drainage across larger sites. Soil and water conditions change across the district, so footing and drainage design starts with a close look at the site.

Services for Colac projects

The principal designs in Revit and provides a 3D BIM model, so you can see your model and how the structure fits together before anything is built.

House designs for new homes, from slab to roof framing
Extensions and renovations to existing homes
Footings for town and rural sites
Retaining wall design
Civil drainage and stormwater plans for houses and larger blocks
Stage inspections while the build is under way, plus checks on older buildings

The wider service area

From Colac, the service areas run out to Geelong, the Bellarine, Warrnambool, Torquay, Anglesea, Lorne and Apollo Bay.
