Frequently asked questions
Do I need a geotechnical report for a building consent in Auckland?
Usually yes, unless the site can be shown to have good ground as defined in NZS 3604. Auckland Council will typically require a geotechnical report where the site is on a slope steeper than about 1 in 5, has fill of unknown origin, sits within a mapped landslide or coastal hazard area, has soft or peaty soils, or where the design falls outside NZS 3604 and needs specific engineering design. If the site is flat, on undisturbed natural ground, and the building is a standard NZS 3604 dwelling, a report may not be required, but the ground still has to be verified.
What does a geotechnical report include?
A geotechnical investigation report for building consent normally contains a desktop study of published geology and council hazard records, a site walkover, intrusive investigation such as hand auger or machine boreholes with Scala penetrometer or CPT testing, laboratory testing where required, a ground model describing the soil profile and groundwater, an assessment against the good ground criteria of NZS 3604, allowable bearing capacity and settlement estimates, geohazard assessment covering slope stability and liquefaction where relevant, and specific foundation recommendations. It is signed by a Chartered Professional Engineer.
What is good ground under NZS 3604?
Good ground under NZS 3604 is ground with an ultimate bearing capacity of at least 300 kPa that is not subject to erosion, subsidence, slippage or liquefaction, does not contain uncontrolled fill, and is not on a slope steeper than 1 in 5 or within the zone of influence of such a slope. If any one of those conditions is not met, the site is not good ground and specific engineering design is required.
Who prepares and signs your geotechnical reports?
Our geotechnical reports are prepared and signed by Chartered Professional Engineers (CPEng) registered with Engineering New Zealand, working to NZS 3604, MBIE guidance and New Zealand Geotechnical Society guidelines. Chambers Consultants is based in Papatoetoe, Auckland, and works across Auckland, Northland and New Zealand wide.
How do you decide what type of in-situ tests are best for a given site?
We evaluate the site’s soil conditions, project requirements, and potential risks to choose the appropriate in-situ tests. For instance, Standard Penetration Tests (SPT) are common for general soil strength, while Cone Penetration Tests (CPT) provide detailed soil stratigraphy. The site’s specific needs drive the test selection.
Do your digital reporting tools speed up turnaround time for urgent projects?
Yes, our digital reporting tools significantly speed up turnaround time for urgent projects. By utilizing cloud-based systems, real-time data sharing, and automated reporting, we can quickly analyze, process, and communicate findings, ensuring faster decision-making and a more efficient workflow for time-sensitive projects.
Can stakeholders view geotechnical data in real time through your cloud platform?
Yes, stakeholders can access geotechnical data in real time through our cloud platform. This enables seamless collaboration, quick decision-making, and easy tracking of project progress. The platform provides up-to-date reports, data visualizations, and insights that all relevant parties can access anytime, anywhere.

How often do lab findings significantly change the course of a project’s foundation design that you mentioned in your geotechnical report?
Quite often. Lab results like unexpected soil strength, moisture content, or compressibility can lead to redesigning from shallow to deep foundations, or adding ground improvement measures.
Clear, thorough documentation like this gives developers confidence to move forward efficiently.
Proactive risk identification can save projects from costly surprises
What are some of the most common risks you identify in residential developments for your geotechnical reports?
In residential developments, some of the most common risks we flag in geotechnical reports include:
1.Soft or compressible soils – Can lead to settlement problems, cracking in slabs, or uneven floors if not addressed with proper foundations.
2.Expansive clays – Swell when wet and shrink when dry, causing movement that can damage walls, driveways, and services.
3.High groundwater levels – Increase the risk of flooding, seepage into basements, and difficulties during excavation.
4.Poor drainage or surface water runoff – Can weaken soil strength and create erosion issues over time.
5.Slope instability – Even minor slopes can present slip risks if the soil is weak or water-logged.
6.Presence of fill materials – Uncontrolled or poorly compacted fill may settle unevenly, requiring remediation.
7.Seismic risk factors – In earthquake-prone areas, liquefaction potential or lateral spreading can be a concern.
These risks don’t mean a site can’t be developed, it just means the design and construction plan needs to address them early to avoid costly fixes later.
Your borehole sampling process sounds incredibly thorough. Would love to see it in action sometime!

Can reports influence construction methodology or sequencing?
Yes, geotechnical and structural reports can significantly influence construction methodology and sequencing. These reports provide essential data on soil behavior, groundwater conditions, load capacities, and structural constraints, all of which affect how and when specific construction tasks are carried out.
Are reports tailored for regulatory submission and approvals?
Yes, our reports are specifically tailored for regulatory submission and approvals, ensuring they meet all council, compliance, and industry requirements. We structure every report so it is clear, defensible, and aligned with what regulatory authorities expect, which significantly speeds up the approval process.
Are recommendations actionable for contractors and engineers?
Yes. Our recommendations are practical, clear, and written so contractors and engineers can apply them directly on site.
Are historical site conditions considered in reports?
Yes, we review available historical records, past site use, and previous investigations to understand potential risks. This helps us identify legacy issues that may affect design or construction.
How often do findings in reports change the initial design?
Report findings lead to design changes when site conditions differ from initial assumptions, such as unexpected soil behavior, groundwater levels, or load constraints. This is fairly common in complex or constrained sites and is addressed early to avoid issues during construction.
In many cases, the changes are refinements rather than full redesigns, helping improve safety, performance, and cost efficiency while keeping the overall project objectives on track.
Optimizing designs to reduce over-engineering is a smart approach to both sustainability and cost control.
