Phase 1 Geotechnical Assessment

Desk studies and walkover surveys can provide a valuable insight into the likely ground conditions beneath a site at relatively little cost.

Using a combination of historical and geological information, combined with aerial imagery, internet-based research and other data sources, a ground model can be produced to identify geotechnical risks, to guide/ target the next phases of investigations and/ or to provide early indicators of ground-related development costs/ constraints.

Preliminary Sources Study Reports in accordance with HD 22/08 are specifically produced for highways infrastructure projects.

Case Study

Pre-Purchase Phase 1 Geotechnical Assessment Provides Cost-Effective Information

Ruddlesden geotechnical were commissioned to undertake a Phase 1 Geotechnical Assessment on behalf of a national housebuilder at an existing golf course in Dorset.

Following a review of the desk study information and the consultation of historical maps, geological maps and memoirs, a walkover survey of the site was undertaken. This information allowed a ground model to be produced, which was used to identify the geotechnical risks and current uncertainties with regards to the proposed residential redevelopment of the site.

The site was zoned, based on the anticipated ground conditions, and recommendations covering foundations, excavations, surface water drainage and slope stability were provided.

The findings of the Phase 1 informed the scope of works for the Phase 2 deotechnical investigation and contamination assessment and ultimately provided the client with an understanding of the development constraints, opportunities and forecasted development costs for the site, prior to committing to the purchase of the site.
