Project Overview

The John Gorton Building is located in Parkes, ACT, accommodating staff from two prominent Government Departments. The building was originally constructed in 1956 and has recently received significant restoration and upgrades to preserve its heritage values.

In 2015 Complex was engaged to deliver the John Gorton Building Carpark Upgrade project. The original scope of works included demolition of the existing carpark and construction of a new carpark with hard and soft landscaping features. During construction, additional works to refurbish the main building entrance, strengthen existing lightwells and waterproof the basement office area were incorporated into the project.

Construction featured; carbon fibre strengthening, concrete capped “Wolfin” waterproof membrane installation, granite segmental paving, exposed aggregate paving with inlayed corten steel, LED lighting, bespoke timber/concrete street furnishings, stormwater harvesting tree pits and significant landscape plantings. The works were completed without any major safety, environmental or quality non- conformances and featured as a finalist in the 2018 CCF and MBA awards.
