The switching station allows for electricty to be managed between three underground HV AC & DC circuits between multiple substations. Tony Gee carried out platform earthwork and drainage designs for the facility across a two-year period

Tony Gee used InfraWorks software to produce detailed 3D images of the building on the proposed site which had allowed for the rapid producing of images from any angle during the initial site assessment. The engineering design was developed to have a reduced visual impact with which the key aim was integrating the earthwork screening into the landform adjacent to the facility.
A key challenge had been the drainage design given the site being located adjacent to a low point in the adjacent field with consequently high water table.
