Geotechnical Reports
A geotechnical report is essential for safe construction, evaluating a site's subsurface conditions. It details soil, rock and groundwater properties through field tests like hand auger geotechnical boreholes or test pits, and analysis to identify hazards. Our range of engineering geology services also includes liquefaction assessment and slope stability assessments. Tailored for projects like residential dwellings in New Zealand, geotechnical site investigation ensures compliance with the New Zealand Building Code (NZBC) and MBIE seismic guidelines, informing geotechnical design parameters for foundations or retaining walls.
A geotechnical investigation 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 applications, detailed site investigation 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)
