Geotechnical Reports
A geotechnical report evaluates a site’s subsurface conditions to guide safe construction. Through field tests (such as hand auger boreholes or test pits) and analysis, it details soil, rock, and groundwater properties, identifying hazards such as liquefaction or slope instability. Tailored for projects like residential dwellings in New Zealand, it ensures compliance with the New Zealand Building Code (NZBC) and MBIE seismic guidelines, informing design parameters for foundations or retaining walls.
A geotechnical report offers key recommendations, including foundation types, bearing capacities, and risk mitigation (such as slope stability measures, ground improvement, or deep piles), ensuring stability and a 50-year durability in accordance with the NZBC Clause B2. Essential for building consent application, it supports safe, compliant designs, protecting dwellings and adjacent properties.
Some examples of the purpose of a geotechnical report include:
Due diligence when purchasing a property
Supporting building consent application for residential or commercial development
Supporting resource consent application to subdivide a property
Hazard analysis and mitigation
Drone imagery of the site can be supplied (where applicable)
