Quadrant Arcade, Regent Street, London
Quadrant Arcade is a Grade II listed enclosed retail street located in the southern end of Regent Street in central London. It is owned by The Crown Estate. Working alongside Project Managers Buro4, Architects Barr Gazetas and permanent structural works design Engineer Watermans, Civic Engineers have prepared proposals for the temporary works to allow the removal of the central column at the front of the arcade, between the ground and second floor level.
200 tonnes of load is needed to be transferred into a temporary structure and then jacked into a new permanent steel frame arrangement whilst the building above remains in full operation. The detailing of the temporary structure, jacking conditions and sequencing of the works is extremely complex.
The removal of the column is to provide a more spacious opening into a refurbished arcade entrance.
