AECOM’s rail specialists are delivering mechanical, electrical and plumbing (MEP) design services for the West Link (Västlänken) — a major underground rail infrastructure scheme in central Gothenburg, Sweden.
We’re performing our work on two sections of the scheme. The first involves the basic and detailed MEP design for the new Haga underground rail station, a 300-metre concrete box including shafts for entrance and ventilation.
The second element relates to MEP design for the Kvarnberget section of the West Link tunnel. This proposed infrastructure has 560 metres of main rail tunnels and 120-metre-long service tunnel and associated shafts.
Our rail specialists in Madrid are delivering the overall MEP design, while our office in Stockholm is providing local coordination and contract administration.
Providing optimum solutions
Following the client Trafikverket’s decision to upgrade the station layout from two to four tracks, AECOM performed a revision of the basic design. In addition, our experts conducted an investigation on how to optimise the existing space and ventilation.
Accepted by the client, our solutions reduced the amount of excavation required, saving the time and cost. As part of the innovation commitment on the project, we proposed several solutions. This included a geothermal energy system in the station box structure.
