DA & CDC Geotechnical Support questions

Can you guarantee council approval?+

No consultant can guarantee an authority’s decision. We can provide clear, relevant and defensible geotechnical information addressing the agreed request.

What documents should I provide?+

Send the latest architectural drawings, survey, structural concept if available, planning or certifier request, and previous reports for the site.

Can you respond to a request for further information?+

Yes, where the request concerns our geotechnical scope. Additional investigation or analysis may be needed if the authority raises a new issue or the design changes.
