Shallow Geotechnical Testing
These reports are required by council for every new build, extension and many types of renovation
We use a scalar penetrometer to measure soil bearing capacity. Logs of soil type are generated using a hand auger or a small excavator.
These tests determine what kind of foundation is required
Foundation Design
We typically design concrete slab or timber pile foundations. The slabs usually include foam pods for insulation and to enhance slab strength.
The foundation design depends on the size and weight of the building, and the bearing capacity of the ground – it’s strength, cohesion and risk of liquefaction.
Review of Building Consent Applications
Unfortunately, more than 50% of building consent applications in New Zealand face delays in council processing because of incomplete design information.
When the council issues Requests for Information (RFI’s) it slows down the job and costs you money. Both the designer and council will charge you extra. The more RFI’s , the more you pay.
Branch Consultants are certified Building Consent processors. We can check your building consent application and quickly identify outstanding issues that will hold up your consent.
Earthquake Assessment
Earthquake damage is common on most older houses in Christchurch. Many houses offered for sale have structural damage, or poorly executed EQC repairs.
We have carried out many, many assessments of Earthquake Damage as part of pre-purchase inspections or for Insurance purposes. These reports can be as simple or as detailed as you need them to be, depending on the issue and your budget.
Structural Engineering
We cover all aspects of residential structural engineering. From Architect led builds with complex elements to multi story townhouses, and simple renovations
3D Geological Modelling
New builds or developments taking place on hills or in technically difficult locations will benefit from 3D modelling in the design phase.
This can assist with understanding the geotechnical properties of the site, and the design of buildings and services with respect to areas of geotechnical hazards and drainage.
We construct topologically accurate 3D models of the surface and the subsurface, using drone imagery, LINZ data and geological investigation methods.
