The EQC GIPP project was undertaken in Christchurch during 2014 and 2015. It encompassed 28 properties spread across 17 locations and construction of the following types of ground improvement works:
- Gravel rafts,
- Stone columns,
- Soil-cement rafts, and,
- Driven timber piles.
The primary objectives of the EQC GIPP were to design and construct a range of ground improvement types across Christchurch residential properties and gain up-to-date market data, local experience and costs to construct such works. The information that was gained from this project was compiled and used to develop robust cost estimates and inform the Canterbury Earthquake residential damage claim settlement process.
Tony’s presentation will provide an overview of the EQC GIPP, the key lessons learnt, and, the main outcomes that are of particular interest to Geotechnical and Civil engineers who may design and/or manage such works in the future.
