Project Overview

Located on Northbourne Avenue, the Sydney and Melbourne Buildings form the gateway to the Canberra City precinct. Their stretching collonades are lined with restaurants, retail shops and bars, rich in history and heritage value. In a bid to revitalise and improve access in the area, funding was allocated to upgrade and extend the verges, providing additional space for retailers, cyclists and pedestrians.

Key elements of the project included; reclaiming of a section of road verge, removal of stepped thresholds at the building colonnades, upgrade of stormwater infrastructure, construction of vaulted tree pits, planting of mature street trees, high end granite paving, architectural street furnishings, raised cycle lanes, LED feature lighting and traffic signal upgrades.

Working in close proximity to the heritage listed buildings and local businesses proved a challenging aspect of the project. Complex worked tirelessly to manage these elements, performing much of the works out of hours and using small capacity plant to reduce noise and vibration. The project was completed without any major safety, quality or environmental incidents, and has received overwhelming positive feedback from all major stakeholders
