Climate resilience is at the forefront of Hawke’s Bay Regional Council and stopbanks are at the heart of protecting our communities from the impacts of climate change. Thirty nine (39) stopbanks required assessments to upgrade from 1:100 year to 1:500 year flood events. Many of these stopbanks require strengthening and raising the banks to protect communities from the future flood events.
RDCL deployed a rapid screening process across several long sections of stopbanks and a seismic survey (MASW), which allowed targeted investigations of anomalies within the stopbanks. Targeted investigations included CPT, geotechnical drilling and Test Pits. This data gathering allowed engineering inputs for Failure Modes and Effects Analysis (FMEA).
RDCL produce geotechnical retention designs and supervised earthworks construction on the Taradale Stopbank.
RDCL keys benefits were;
- Supplying rapid screening geophysics across stopbanks, achieving up to 2km a day
- Local experience and engineering knowledge with construction supervision call-outs at a moment’s notice.
