THE CHALLENGE

IKM was contracted by BP to undertake a phased geo-environmental ground investigation at a site located on the banks of the Firth of Forth.

During the desk study phase, IKM highlighted that there were many access and egress issues which would hinder the ground investigation. These included; the requirement to install two new access gates (without comprising security to the asset), the presence of an underground septic tank and associated underground pipe work, a vegetation scrape, the topology of the site (undulating with steep banks) and ecological constraints (nesting and breeding bird surveys were required due to the time of year). Service drawings highlighted an 11kV cable which ran through the centre of the site.

THE SOLUTION

IKM at an early stage were able to devise a solution, taking into account site regulations and restrictions, to allow the ground investigation to continue without the risk of striking the cable or any substantial costs associated with delays. As these potential issues were highlighted within the desk study, they were able to be resolved prior to mobilisation of expensive equipment.

Additionally IKM were able to tailor the original specification to suit the anticipated ground conditions so that appropriate plant and best drilling methods were employed.

Once resolved IKM conducted a two phase ground investigation, Phase 1 included trial pits for contamination and near-surface soils and rotary boreholes to check for obstructions as requested by the client. Phase 2 included cone penetration testing and geophysical surveys.

On completion of the works IKM produced a detailed report which included information for foundation design, the geotechnical properties of the soil, human health risk assessment, water environment risk assessment and waste classification. In addition the client returned to IKM for geotechnical advice, and IKM were able to aid with the planning application for the site.
