Location:Whanganui, New Zealand
Project Duration: Jan 2019 – May 2019
Client: SET Engineering, on behalf of Housing NZ
Geotechnical investigation and assessment for subdivision of 5 sections into a total of 19 new lots for development by Housing New Zealand.
Geotechnical engineering advice was sought for the subdivision of the sections, with the advice required in a relatively short time frame. The ground conditions varied within the sections and across the sites, with areas underlain by soft soils and potentially liquefiable soils.
Miyamoto undertook a detailed desk study of the areas including retrieval of a number of documents from Council archives, and scoped and undertook the required investigation works which included shallow investigation techniques and soakage pit testing. Based on the results of the desk study and investigation Miyamoto produced Lot-specific geotechnical reports including assessment of the future seismic performance of the land and recommendations for innovative foundation options (modified NZS3604 foundations), that are suitable for the expected land performance and could be easily constructed using readily available materials. Miyamoto also provided construction monitoring services for the construction works and were on hand to provide design alterations as required.
Miyamoto provided proactive communication and delivery of the project in a timely manner and is proud to have provided effective solutions for HNZ and future tenants.
