Bovis Lend Lease and Willmott Dixon are the two contractors selected for the final shortlist on the £300m Wandsworth Building Schools for the Future contract, after Galliford Try was eliminated from the race.
The two firms will now begin further dialogue with the council and draw up detailed plans for investment in two sample schools, Southfields Community College and Burntwood School.
Final bids will be submitted in the summer with a winner due to be announced in the autumn.
The contract covers work across all 16 of the London borough’s state secondary schools.
The sample schools will be the first to be transformed under the programme, and outline planning permission for both has already been granted. Work on these schools is scheduled will start in spring 2011.
A new Catholic secondary school, Saint John Bosco, will also be built during the programme, and Elliot School in Putney will be completely remodelled.
Council leader Edward Lister said: “We’re delighted to announce our final shortlist of two for this exciting project. BSF will completely transform the borough’s secondary schools and will help us provide the best possible education to all the borough’s children.”
