Scope overview
The aim of this project is to increase the level of flood protection provided by the Waipaoa stopbanks up to a 100 year return period accounting for climate change effects out to 2090. Bulk earthworks are required to raise and widen the existing Waipaoa stopbanks to improve their resilience against flood events.
This 2yr Contract involves undertaking bulk earthworks (approx.300,000 m3) to raise and widen about 17km of the existing Waipaoa stopbank, and including the renewal of existing pipes laid through the stopbank in that area. All the soil material for this work will be sourced from Council-owned berm land located beside the stopbanks.
The scope of works also includes the full renewal and replacement of about 25 culverts/pipes laid through the stopbank along the alignment. This Contract spans two construction seasons.
