Modifications to the design of High Speed 2’s (HS2) Birmingham Interchange station have knocked 12 months off the construction programme, New Civil Engineer can reveal.
The station building will now be built on land to the side of the tracks rather than above as originally planned.
HS2 said the change greatly simplified and reduced the time needed for construction of the station meaning around 12 months had been taken off the programme to build it.
The prequalification questionnaires (PQQs) will now be published next spring as construction on the station no longer needs as long a lead in time.
A PQQ for neighbouring Curzon Street Station is still planned to be published later this month.
HS2 Interchange Station now being built to one side
Consultant Arup is carrying out both the architectural and engineering design for the Interchange Station alongside the design of HS2’s London terminus, Euston Station in a deal worth £60M to £70M.
The design for Interchange is now in the detailed design phase with station building plans to be submitted early next year, for a request for approval under Schedule 17 of the Act to the local planning authority.
Interchange in Solihull, will be the penultimate stop before the high-speed service terminates in Birmingham city centre at Curzon Street Station. It will contain two 415m long platforms serving nine trains per hour in each direction. There will also be a new Automated People Mover system serving Birmingham Airport, Birmingham International Station and the NEC.
In parallel to the design of the station, Arup is also looking into an additional set of aspirations set out by the Urban Growth Company – set up by Solihull Council to maximise the benefits of HS2’s arrival – to further integrate the station into the surrounding infrastructure.
The additional elements were given the green light after a £10M funding package was approved in March this year.
The “aspirational outcomes” include multi-modal transport connectivity to include future transport connectivity for Metro trams and Sprint buses, a change of location of the drainage ponds to free up land for development and a provision for utility crossings over and under the line to facilitate future developments.
The alignment of the APM is also being looked at to see if it can be fully integrated with the soon-to-be redeveloped Birmingham International Station.
Revised images for the two northern stations were released in October this year.
Construction on Interchange is planned to start in 2019 and open in 2026 along with the remainder of HS2 Phase One.
