As temporary works, they rarely come more complex than this one.
The lighthouse building was constructed Circa 1870 over two cut and cover tunnels now owned by LUL and NWR.
The existing construction comprised a terrace of buildings with masonry cross walls at approximately 6m centres supported off cast iron spreader beams onto the brickwork tunnel arches.
The construction method has required maintaining positive load on the girder beams during demolition of the cross walls and replacement with new structure loadings.
Pure Structures role has been in carrying out temporary works design for the retention of the historic façade and Lighthouse structure during the re-development.
As part of this we have been central to finalising the construction method and the analysis and reporting of the monitoring regime agreed in advance with LUL and NWR.
The Phase I project is largely progressed beyond the temporary works stage and PSL have been appointed as Temporary Works Designer for the equally challenging Phase II re-development of the rear of the site over Kings Cross Bridge.
