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
