In early 2014 we were engaged to undertake geotechnical site investigations on proposed tank sites for Tasman Tanks across the West Coast, Canterbury, Tasman and Marlborough Regions.
There have been a number of sites which required some geotechnical design and ground improvement prior to the construction of these dairy effluent tanks.
Usually a site visit with Dynamic Cone Penetrometer testing provides sufficient information for construction recommendations where the ground conditions do not comply with NZS3604 definition of "Good Ground". The follow up normally has required the production of a PS4 (Producer Statement) to confirm that the proposed site preparation work has been undertaken to the specified standard.
We have developed a set of fixed rates for these tasks which allows clear budgeting for the client and cost effective solutions.
Additionally we have acted as Agent for some clients, assisting in production of Consent Documentation.
