This project involves the construction of a new floodgate structure in the Mahunga Stream approximately 300m downstream of the existing floodgates at State Highway 2 in Ormond, along with the associated construction of stopbank upgrades to tie into the adjacent stopbank system.
The scope of work for this project includes sheetpile and cast-in-situ concrete structural construction, general earthworks and grading, installation of structural appurtenances (railings, walkways, etc.) installation of rock rip-rap stream armouring to stabilize the stream/stopbank, and effective management of flows within Mahunga Stream for the duration of construction.
The soil material for this work will be sourced from adjacent Council-owned river berm land located adjacent to the site.
The construction of this new floodgate is part of a 10yr construction programme that started in 2019 to increase the level of flood protection provided by the Waipaoa River Flood Control Scheme (65km of earthen stopbanks) up to a 100 year return period accounting for climate change effects out to the year 2090.
This tender has been awarded.
