With the technical designs, surveys, and specifications already completed for the 23-storey tower blocks, the pre-construction phase will start imminently.
McLaren Construction will deliver fire safety repairs to the Bray, Burnham, Dorney and Taplow towers on the Chalcots Estate.
Work will start on site this month and the new cladding installation will begin in the summer as part of a schedule of works that will see the contractor working on two towers at the same time.
The works include full window replacement, renewal of flat roofs, installation of building maintenance units (BMUs), replacement of brickwork to the ground and first floor levels, including vents, louvers and canopies as well as insulation to the undercroft as required.
Related works will include radiator installations, internal making good and decorating as well as installation of relevant power supplies to BMUs and louvers.
Due to its different structure, a separate two-stage design and build’ contract has been awarded to John Graham Construction for the fifth tower block on the estate, Blashford. This will allow for works to start on the building sooner than would have been the case if Blashford was part of the same contract as the other tower blocks, the council said.
The Chalcots Estate, in Swiss Cottage,. Chalcots Estate is a 1960s council housing estate on Adelaide Road and Fellows Road in Swiss Cottage. It was evacuated in 2017 after the Grenfell Tower fire. This was because it had been refurbished (at a cost of £66m) in 2007-09 by Rydon as main contractor working with Harley Facades – the same team behind the Grenfell Tower refurbishment. In each case outer cladding panels, made up of aluminium panels with a polyethylene core, were ultimately revealed as not safe.
