South Road Superway Project

The AUD 842 million South Road Superway project is the biggest single investment in a South Australian road project, and the state’s most complex engineering road construction project to date. The South Road Superway is stage two of the north-south transport corridor upgrade and will deliver a 4.8 kilometre non-stop corridor, comprising of a 2.8 kilometre elevated roadway, from the Port River Expressway to Regency Road.

Our involvement

Aquenta was engaged to develop the final investment budget together with the Engineers Estimate for the project and was an integral part of the selection panel during the negotiation phase. Our team streamlined the financial selection criteria by developing a common work breakdown structure early on in the procurement phase. Maintaining a common pricing structure and method of measurement between competing consortia reduced the financial comparison significantly.

The outcome

During the final planning for the project, Aquenta contributed extensively to the engineering workshops providing sound and real constructability advice which in turn was supplied to the consortia. Our team assisted in saving tens of millions of dollars in the final negotiations and continued to provide assistance in providing contract variation advice.
