Batemans Bay Bridge
Snapshot
The Bateman’s Bay Bridge project was initiated by Transport for NSW to replace the existing bridge over the Clyde River. The scope of the project included upgrades to several road approaches along the Princess Highway as well as surrounding local roads. This was undertaken to provide more reliable connections across the river, improve traffic flow and therefore access to Batemans Bay.

Highlights
Accelerated utility approvals
Turnbull worked closely with the constructor and utility owners to accelerate approvals to construct utilities. A dedicated approvals program and team allowed resources to be focused.
Value engineering without delays
Turnbull identified multiple opportunities to modify the project scope in order to reduce cost and construction time associated wtih utilities and traffic staging. To avoid delay, Turnbull allocated additional resources to drive the value engineering options alongside the original program.
3D models to drive certainty
We provided comprehensive 3-dimensional modelling of utility elements. This was conducted to a level of detail beyond that generally adopted throughout the industry. This resulted in a greater certainty of model information and efficiency in the coordination of the utilities model.
Scope

Effective Delivery of High-Risk Scope
Turnbull managed high-risk design elements: Utilities, temporary boat ramps and construction staging.
Flexible and Responsive
While the Turnbull team was located in Sydney, over 4 hours’ drive from the site, they travelled to site regularly during design to meet with the constructor, utility authorities and the client to ensure constraints were thoroughly understood.
