Three fit-out specialists are chasing an interiors contract for the 70,000 m2 Shell Centre in Waterloo, south London.

ISG InteriorExterior, Bovis Lend Lease and Overbury are understood to be in the running for the contract, which could be worth up to £100m. Shell has sent out prequalification documents for the scheme.

The work involves fitting-out and refurbishing the premises. It comes at the same time as Shell is seeking to rejuvenate its brand, which suffered last year after claims that it had overstated its oil and natural gas reserves.

The scheme is being designed by HOK, which beat fellow US architect Gensler in July.

Other firms involved in the scheme include project manager Mace, consultant Gardiner & Theobald and M&E contractor Hurley Palmer Flatt.

Deputy prime minister John Prescott approved construction of the scheme last year, after a year-long public inquiry overturned a previous decision by Lambeth council to refuse planning permission.

The council had turned down the planning application for a series of reasons, including the proposed building’s height and bulk, the fact that it overlooked the north block of County Hall, the impact the retail space would have on businesses in the area and the loss of open public space.

The original scheme had been revised several times and approved by planning officers, but was rejected by councillors on the planning committee.

The scheme is part of the wider regeneration of the South Bank, that includes the mixed-use Bankside 4 scheme, sold from Land Securities to a Grosvenor-led consortium in October.
