An appropriate site investigation is a key element in the management of geotechnical risks.
Halcrow’s approach embodies the following aims:
- thorough desk study of pre-existing information
- geomorphological interpretation of landforms
- phasing of investigations (if practicable) focussing the scope in each phase on the project risks that matter at that stage
- selection of appropriate investigatory / boring technologies
- integration of phasing with regulatory requirements
- ensuring that geotechnical investigations are optimised and cost-effective as a result of:
- thorough desk study of pre-existing information
- geomorphological interpretation of landforms
- geomorphological interpretation of landforms
- phasing of investigations (if practicable) focussing the scope in each phase on the project risks that matter at that stage
- selection of appropriate investigatory / boring technologies
- integration of phasing with regulatory requirements
- specification of appropriate laboratory and in-situ testing, and ground instrumentation, based on a thorough understanding of the geotechnical design requirements
- application of state-of-the-art geophysical techniques (surface and downhole) where likely to be of value, particularly to optimise targeting of exploratory holes
- experienced supervision to ensure quality of sampling procedures and in-situ testing
- efficient management and presentation of data from investigations and instrumentation monitoring, using database software
- interpretation of data by staff with detailed knowledge of local conditions and the requirements of the geotechnical design.
