Grimshaw has won the race to design the huge £1billion Northern Line extension, including new underground stations at Battersea Power Station and Nine Elms
The practice, which is already working on the massive HS2 and Crossrail projects, is part of the Ferrovial/Laing O’Rourke joint venture which has been named preferred bidder for the six-year contract.
It is understood Grimshaw, which increased its turnover by 44 per cent to £24 million according to its latest trading figures (AJ 07.01.14), will need to take on about 40 extra staff by the start of next year to handle the job.
Grimshaw and engineer Mott MacDonald are drawing up designs for all the station work, including the platforms and over-site developments.
The team beat three other rivals: Bam Nuttall and Balfour Beatty with CH2M Hill (formerly known as Halcrow), Buro Happold and Acanthus Architects LW; Bechtel and Strabag with Arup; and Costain, Dragados and Sir Robert McAlpine with Atkins and Weston Williamson.
The proposed start of construction for the Northern line extension is spring 2015. Subject to funding and permission to build and operate the extension, the new stations at Nine Elms and Battersea could be open by 2020.
According to TFL, the extension will kick-start regeneration in the Nine Elms area, where Kieran Timberlake is currently overseeing the construction of the new US Embassy (pictured below), and ‘provide major transport benefits’.
Grimshaw’s appointment is subject to a 10-day standstill period. The practice refused to comment.
The news of Grimshaw’s victory emerged as work began on dismantling Battersea Power Station’s four iconic chimneys, with the first to be taken down on the south west corner of the Grade II-listed landmark.
The 101m chimney is being demolished from the top downwards using a circular rig which ‘munches’ its way down the tower, collecting the debris and enabling it to either be re-used or conserved as part of the development’s legacy programme.
It is expected it will take five months to take apart the first chimney. Once the rebuilding process begins the chimneys will be rebuilt from the base up in 1.2m stages, using concrete and reinforcement.
