The project, which is part of a four-year technical and commercial consultancy services framework, will be lead from Scotland.
The framework provided by WSP | Parsons Brinckerhoff will sustain the ongoing modernise project being undertaken by Metro, which will include new tracks, power lines, revamped stations and refurbished trains.
WSP | Parsons Brinckerhoff will also provide consultancy in station design, transport and highways infrastructure, civil and structural engineering, building services, safety quality and environment, and programme and project management.
Chris Reid, who has been named project manager at WSP | Parsons Brinckerhoff, said: “Being part of this framework is a testament to the strength of our combined transport and infrastructure offering in the North East.
“We look forward to supporting Nexus in their drive to modernise the 35 year old light-rail system so that it can continue to serve the public long into the future and be better equipped to serve growing passenger number in Tyne and Wear.”
