BRISBANE AIRPORT’S NEW RUNWAY IS A CRITICAL PART OF A MULTI-BILLION DOLLAR INVESTMENT INTO CAPACITY-BUILDING INFRASTRUCTURE.
At 3.3km long, 60m wide, Brisbane Airport’s new runway is located two kilometres to the west of the existing main runway. It features more than 12 kilometres of taxiways, navigational aids, airfield infrastructure and hundreds of hectares of airfield landscaping. The biggest aviation project in Australia at the time of completion, it means Brisbane Airport possesses the best and most efficient runway system in the country.
BAC reclaimed 360 hectares of soft marshland by pumping 13 million cubic metres of sand onto the site. Over four years, the weight of the sand, working with 330,000 wick drains funnelling the water to the surface, created a solid base for the runway and taxiways. The new pavement is 3.3 kilometres long, 60 metres wide and has 12km of taxiways. Environmentally sound and award-winning, the project created 2,700 jobs during the construction phase.
Ranbury initially provided constructability advice and estimates of construction costs for various parts of the proposed works with the role expanding over the course of the project to include that of Project Cost, Constructability, and Risk Adviser.
As the project moved into the detailed design and construction phase, Ranbury’s role was further extended to include Scheduler and Commercial Adviser for tender selection advice to BAC for the major packages.
As appointed Cost Planner, Programmer and Commercial Adviser, we provided the following services:
- Time Management
- Cost Management
- Constructability Advice
- Tender Evaluation Assistance
- On-site construction manager secondment for civil and dredging packages.
Our consultants worked closely with our client to ensure project goals were successfully achieved. The project won an Excellence Award in the Environmental category of the 2014 Queensland Engineering Awards. The runway was completed and officially opened in July 2020.
