In the pre-planning phases of the project it was noted that due to the proximity of the deeper boreholes to the rail tracks and access constraints, the use of the cable percussive rig detailed in the client specification was deemed inpractical. It was recommended by Geo-Environmental and agreed by Osborne that a Comacchio 205 multipurpose rig would be best utilised for the deeper boreholes. On a project such as this, where there are both health and safety concerns and difficult drilling conditions, it is important to employ a Company that has both the track record and skilled staff to advise you. Our advise on this project reduced the risk of any project delays and cost overruns. As an organisation Geo-Environmental has been providing geotechnical and environmental consultancy, and ground investigation services since 1996 and has been working in the rail sector since 2007. We have provided services in a range of rail settings that have covered high-speed, interurban and commuter services, along with heritage lines.
