Points of note
Added extrasAs delivery partner to Network Rail, we’re oversaw the delivery of the structures and clearances portfolio – ensuring that it was possible to install overhead line equipment (OLE) and wires along the 235 mile (380km) track. We also monitored building and civils activity at stations and along the route. And we have identified access points for OLE plant, requirements for track lowering and areas needing clearance for OLE installation.
Saving £16mAround 150 overhead power lines were originally identified for relocation but, with the process to arrange outage dates with National Grid potentially taking five years, this would have delayed the programme. Our experts therefore reviewed the plans and came up with a solution that left some cables in place. We have identified a further four areas where similar solutions could be implemented, which together will save around £16m.
Trained utilities expertiseIn addition to project and programme management support, we put our utilities team to work on this mammoth project. They liaised with contractors and electricity distributors, leading complex legal discussions. One successful outcome was achieved through intensive negotiations with an electricity provider. Their agreement that high voltage overhead cables would be diverted in time for electrification of the train test track avoided programme delays.
“Mace’s Utilities Management Service team has already made a significant impact in the delivery of utilities diversions, which has been welcomed by our project managers, contractors, and utility companies alike. Its key contribution is enabling the GWLE delivery programme to stay on track – a stunning success, well done.”
