CON001926 - Whakatane Project Future Proof - Stage 4A

The Bay of Plenty Regional Council is seeking a suitably qualified civil construction contractor to deliver Stage 4A of Whakatāne Project Future Proof, a key component of the ongoing flood resilience improvements along the lower Whakatāne River. Stage 4A is located adjacent to the Whakatāne Boat Ramp and will replace and upgrade a section of the existing flood defense network while maintaining flood protection throughout construction.

Briefly, the physical works include: • Location, protection and management of all existing services during construction. • Establishment of the work site, temporary access arrangements, environmental controls, laydown and stockpile areas, and traffic management. • Site clearance, including removal of vegetation, obstructions, existing pavement, kerb and channel, sections of existing floodwall, and associated water services. • Excavation and pavement reconstruction works, including new kerb and channel, concrete surfaces, footpaths and associated reinstatement. • Removal, relocation and reinstatement of existing water supply infrastructure and associated pipework. • Construction of a new floodwall, including excavation, reinforced concrete footings, stitch pours and installation of precast floodwall panels. • Design, fabrication and installation of flood gates at vehicle access locations to maintain flood protection continuity. • Construction of service penetrations and associated seepage control and drainage measures through the flood protection structure. • Relocation and reinstatement of streetlight poles, services and associated infrastructure. • Earthworks, topsoiling, landscaping and full site reinstatement. • Working alongside the public, boat ramp users, nearby businesses and stakeholders to minimise disruption throughout construction. •
