Dwelling on a classified lot
Geotechnical and Structural
- Ground
- Classified residential lot
- Method
- Shallow testing, then CPT to depth
- Scope
- Investigation and foundation design
- Outcome
- Consented as one package
A lot the council has already classified narrows what a foundation is allowed to be. That is useful information rather than bad news, as long as somebody goes and confirms which category the ground in front of you actually falls into.
Testing settled which category this site actually falls into, and the foundation was designed to suit that answer rather than the one mapped across the wider block. The structure above was then detailed for the movements the category anticipates.
The geotechnical report and the foundation design went to council together, with the producer statement issued by the engineer who did both. One package, one accountable name on it.
The rig sets up where the building will sit, not where the driveway is convenient
A stiffened raft is one of the answers a classification allows, once the testing supports it
Steel is placed to the design schedule and checked before the pour closes it in
Test positions are recorded against the site plan so the report can be checked later
