OUT TO MUNCH: Demolition of four massive post-tensioned concrete cantilevers overhanging the Thames in east London was successfully completed last Thursday. With a maximum cross-section of 4m deep by 600mm wide, the cantilevers were the end sections of roof beams supported by four rows of 25m high precast columns. They provided covered docking facilities at the Seacon Buildings on Westferry Road.
Main contractor Erith used a long reach 'muncher' and a 1,000t mobile crane to remove the cantilevers, with advice from structural engineer Alan Baxter & Associates. Client St James Homes plans to build 16 storey and 12 storey residential towers on the site.
