Working on behalf of the Mayor and Commonalty and Citizens of the City of London, Mackley is nearing completion of a year-long project to construct a new staircase and footbridge to the north east side of London Bridge.
This project, located in the heart of the City of London, involved the construction of a new staircase and footbridge to connect London Bridge to the Riverside Walk. The scheme is part of the Riverside Walk Enhancement Strategy which was adopted in January 2015.
The existing public staircase and footbridge has been removed and replaced by a new steel framed staircase, visual screening and footbridge.
While the previous structure was not clearly visible from the bridge, the new staircase cantilevers over the river to form a striking structure.
The new staircase features York stone paving to landings and bridge treads, LED Lighting in the handrail, a stainless steel handrail and painted steel balustrade.
Andy Bosman, Mackley project manager, said: “The location of the project presented the site team with a number of challenges including a restricted work area and access of only 2m width due to the location on the river path next to London Bridge.
“The project involved the construction of 27 piles in two pile caps, with concrete pumped over 100m through steel pipes due to the restricted access to the location of the pile caps.
“The 25 ton new bridge was lowered into position using a 130 ton crane, which required weekend road and bridge closures.
“With the new bridge in place, the subsequent staircase flight and landing lifts were subject to the right wind and weather conditions.
“Despite the extremely busy and public location of the works, the site team has successfully delivered the project and improved access for pedestrians on the path along the River Thames.”
