Geotechnical Site investigations include both thorough desktop research, as well as visual and subsurface investigation. Our Geotech Team analyse geological and seismic maps, and visit the site. The site visit allows for a visual assessment as well as a subsurface investigation, which includes auger holes and test pits to expose the profile of the layers of soil and rock.
Geotechnical site investigations are required for all residential dwellings, subdivisions, structures and
Geotechnical Investigation Assessment Reports
Our team can provide thorough Geotechnical Investigation Assessment
Reports that summarise the site investigation work. This includes:
- Geotechnical assessment reports for building and resource consents
- Liquefaction analysis, slope stability assessments, seismic assessments
- Commercial, residential and industrial projects
- Soakage testing and design
Land Development and Subdivision technical feasibility assessments
The Tiaki geotechnical team is experienced in assisting developers with pre-purchase assessments. We work closely with the planners and the developer to put together land development and subdivision technical feasibility assessments. This assessment provides advice on the following
- Amount of lots that can be developed
- Roading requirements
- Geotechnical stability of the site
- Flooding and stormwater predictions
- Local authority rules and regulations that apply to that particular piece of land.
Sea Walls and Coastal Erosion
In New Zealand we are surrounded by water, and it is becoming increasingly important to protect our coastlines and existing infrastructure from erosion. Our team can assess and design seawalls and coastal protection structures. This includes designing new structures as well as replacing previous seawalls.
