Desk Study (Preliminary Risk Assessment)
Site investigation requires pre-planning. It is the key to cost effective, on-site success.
To obtain best value from a site investigation it is essential to carry out a desk study as the first stage to identify the geotechnical and/or geoenvironmental characteristics of the ground in sufficient detail to enable economic design as well as to minimise the risk of unforeseen ground conditions which can cause increased costs and/or programme delays.
An ESG desk study:
-
Enables initial understanding of the geological ground model and site history
-
Provides early recognition of site characteristics and potential geo-hazards
-
Aids the scoping of the site investigation
-
Avoids money being wasted on inappropriate methodology
-
Provides early warning of possible delays to programme and/or budget implications
-
Provides information on possible contaminants and anticipated areas of contamination
-
Assists health and safety and geoenvironmental management
-
Is an essential tool for risk assessment and risk management
