Site Investigation

Analysing Below Ground for a Range of Clients

Unforeseen ground conditions may represent the most significant hazards for a construction project.  A site investigation can investigate and pinpoint these potential hazards and significantly reduce risks.  Inadequate site investigation can result in delays to the programme and necessitate a remedial plan to rectify contaminated soils and groundwater and/or re-construct building systems.  Byrne Looby geologists, engineers, environmental scientists and technicians deliver value-added, risk-based, site-specific solutions.  Our comprehensive range of field services can identify the nature and extent and risk of substances found in soil, sediment, surface water, groundwater and building systems.  Our services span the entire lifecycle, including site investigation and feasibility studies, risk assessment, monitoring, remedy selection, remedial design, site reuse, and preparation of competitive tenders to third-party specifications as well as construction management.

Our clients range from individuals to major contractors and developers to constructing energy from waste (EfW) facilities and peaking plant power stations.  We have experience working in challenging environments such as soft Ground, peat bogs, slopes with specialist rigs or scaffold platforms, overwater investigations in harbours, rivers and lakes, landfills, crane lifts and buildings basements and other below-ground structures.

We employ a combination of in-house and third-party resources to undertake site investigations using techniques to maximise the quality of the data obtained.  These techniques include cable percussion boring, rotary open-hole, cored drilling, Geobor and resonance equipment with appropriate flushing mediums to maximise recovery, dynamic (windowless) sampling and probing, static cone penetration testing (piezocone, magcone, seismic cone, gamma cone) and mechanically and hand-excavated trial pits.

We prepare the Ground Investigation Report (GIR), the Geotechnical Design Report (GDR), and specific geo-environmental interpretation and recommendations.  We present exploratory hole and other test data following the current local quality standards (British, EU or the Middle East) and are Eurocode 7 compliant.  The ground investigation data can be presented electronically in the latest AGS format for inclusion in BIM.
