CATEGORY 4: Projects with a value greater than $50 million

Three-stage roading project

The Lincoln Road project was the first of five projects in the Western Ring Route RoNS programme to start after the Global Financial Crisis. The SH16 Lincoln Road Interchange Improvements contract was procured by the New Zealand Transport Agency in March 2010 as an Early Contractor Involvement contract. Fulton Hogan along with designer URS (now Aecom) worked collaboratively with the Transport Agency to fast track the first stage of the project to start construction of the Selwood Road Bridge over the SH16 motorway. Construction started in January 2011 and formed Stage 1 of the project valued at $24 CATEGORY million. Shortly afterwards the Christchurch 4 FINALIST earthquake in February 2011 put a strain on funding and the project was developed collaboratively and let in stages as funding became available. Three stages were subsequently let totalling $138 million, delivering maximum value for the available funding. The project was complex, involving significant ground improvements, bridge construction and deconstruction of old bridges across sensitive coastal marine waterways, and all within a working motorway environment.

Stage 2 of the project (value $29 million) involved the construction of the westbound off ramp to Lincoln Road, which will provide additional capacity for traffic when the Waterview Tunnel opens in 2017. Stage 3 (value $66 million) was made up of all the eastbound widening works and the replacement and widening of Henderson Creek Bridge. Finally stage 3A (value $19 million) included an auxiliary lane from Royal Road eastwards and the widening and replacement of Lincoln No 2 Bridge on the motorway just west of Selwood Road Bridge.

“The project has been technically challenging with deconstruction of multiple motorway bridges over sensitive coastal marine areas and then replacement, and deep ground improvements for seismic stability of bridge approaches and carriageways; all carried out without affecting the daily use of the motorway,” says the company.

The Transport Agency gave the project a PACE score of 83 percent for delivery. Practical completion was achieved in August 2015, excluding the final Open Graded Porous Asphalt (OGPA) surfacing, a month ahead of programme. l
