THREE firms are in the running for a deal to build the tallest building in the City of London, nicknamed the 'Helter Skelter'.
Bovis Lend Lease, Mace and Sir Robert McAlpine have all completed the prequalification stage for the contract to build the £400 million tower in London's Square Mile.
The 288 m-high building, with 60 floors is being developed by German fund management company DIFA and has been designed by architects Kohn Pederson Fox.
Stanhope has recently come on board to assist with the development and management of the contract.
Planning permission was granted at the end of last month and Mace has already been signed up to carry out pre-construction works.
The firm is remaining tightlipped about the extent of work it is carrying out.
A source at one of the other bidders said: 'We have not heard anything on this for a while but we understand it is a two-stage tender process.' A contract award is expected in the next few months and it is anticipated that construction work will start later this year.
The Helter Skelter building will set new heights for developments in London.
It will stand next to the existing 6-8 Bishopsgate Tower, formerly occupied by Barings Bank.
The scheme has been dogged by design problems since it was first proposed in 2001.
The Civil Aviation Authority insisted almost 20 m be sliced off the top of because of safety concerns.
English Heritage and Westminster City Council had already objected on the grounds that the tower would affect views from St James's Park.
The project signals a move towards developing more tall towers in the City of London.
Some of the most recent highprofile schemes include the Heron Tower, The Minerva Tower, 122 Leadenhall and 51 Lime Street.
