LOCATION SH2 Tutira   PRINCIPAL New Zealand Transport Agency   PROJECT DATES January 2010 to December 2010

Design and construction of rail and road bridges as part of the SH2 realignment at Tutira, north of Napier. The rail-over-road bridge consisted of a 40m concrete structure, utilising precast walls and roof with an insitu topping. The road bridge consisted of a 137m three span steel composite bridge elevated approx 70m above a gully. The bridge superstructure consisted of 400t of structural steel with precast deck panels followed by an insitu concrete deck. The substructure and foundations comprised precast pile caps over 1200 x 1500 x 13.5m deep raking bored piles socketed into sandstone.

Programme: The project was completed on time, meeting the client’s expected completion date due to the innovative design approach. This demonstrates Concrete Structures ability to construct complex structures in remote locations within tight time frames.

Quality: Project Quality Plan was implemented and observed in accordance with the Company’s AS/NZS ISO 9001:2008 certification. No significant non-conformances were reported and minimal remedial works were required.

Health & Safety: A site specific Health and Safety Plan Management Plan was implemented and observed in accordance with the company’s secondary level requirements for ACC WSMP. There were zero serious harm incidents.

Environmental: All required and appropriate environmental protection and mitigation measures were followed. These were in accordance with consent conditions and the project specific environmental plan.

Traffic Management: A specific traffic management plan was produced and implemented for this project.

Public Relations & Cooperative team approach: The project required a high level of co-operation, planning and communication between Downers EDI, Concrete Structures, New Zealand Transport Agency, Ontrack and Hawkes Bay Regional Council in order to maintain a safe and open State Highway and rail corridor, as well as mitigating any adverse effects on the water course.
