Cloudy Bay Business Park Reservoir Slope Re-profiling - Marlborough District Council

Site drainage, manhole installation, dish channelling, and approx. 4500 cubic meters of earthworks to achieve the required slope re-profiling recommended following a geotechnical assessment.

The reason for the work is that the existing cut slope adjacent to the reservoir needed to be modified to approximately 45° to improve the factor of safety for slope stability for seismic conditions.

A 20 ton excavator fitted with GPS grade control was used to create a 4m wide bench midway up the slope with batters laid back at 50 deg.
