Location & Overview
Keybridge house was previously owned by BT and is situated on a 1.35-hectare site on South Lambeth Rd, within the 9 Elms regeneration area. The site is approx. 400m from Vauxhall Station, one of the busiest public transport hubs in the Greater London Area, and is in very close proximity to the main Network Rail lines serving London Waterloo. John F Hunt was the principal contractor for the demolition phase of the works.
Work, Challenges & Solutions
The works comprised the total demolition of a 17-storey heavily reinforced concrete tower and 4-storey podium building plus partial demolition of the 2 levels of the existing basement. The tower slabs were 400mm deep supported on 1m square columns.
Part demolition of the 2-level existing basement, including the removal of sections of the 4m deep raft foundations to facilitate the installation of new piled foundations.
Design, supply and install all necessary temporary works to facilitate the demolition process, including propping to the existing basement retaining walls.
Soft strip of the tower, podium, and basement and extensive asbestos removal, including that which was contained within the 4 chimneys.
Real-time environmental monitoring, including dust noise and vibration, was carried out.
Extensive interface with Network Rail and other stakeholders to gain the necessary consent prior to the start of demolition and throughout the works.
