Working for civils contractor Roadbridge, GDG’s onshore renewables team has been designing the structural and geotechnical aspects of the turbine foundations, as well as taking responsibility for the 3D modelling and alignments, floating and founded access tracks, crane pads and substation control building.
The team is working closely with Roadbridge engineers to optimise the alignment and track designs on a site that has locally steep topography, surface water and soft blanket peats.
