The scheme's client, developer Chelsfield, declined to comment on the choice of contractor but confirmed an appointment was imminent. The project team includes architect Jestico + Whiles and project manager Mace.
Carillion is also one of two contractors pitching for a £60m speculative office block in Fetter Lane, central London, for developer Delancey Estates.
It’s puzzling why they are going so fast, though they have a clause in the contract to put it on hold
The firm is vying with Mowlem for the deal – two other rivals, Kier and Bovis Lend Lease, dropped out of the running for the 34,500 m2 project last week.
Sources claimed a decision would be made in early February. One source said the speed with which the contractors were to be chosen was a surprise, given the flat state of the office market in central London. The source said: "It's a bit puzzling why they are going so fast, although they do have a clause in the contract saying they can put it on hold."
The project involves the demolition of an existing building and the construction of an eight-storey block, designed by architect Woods Bagot.
