Raising the roof in London
We were appointed by the University of London to oversee the cranage works for the installation of a 20 ton steel roof-frame, to be lifted over the Grade II listed Senate House, and set in place over the courtyard. A considerable package of enabling works were undertaken to ensure the ground was strong enough to bear the weight of the crane and load. An added concern was that the works were taking place above an electrical switchroom.
The solution was the temporary installation of a framework of steels below street level. At the time of cranage outriggers were carefully lined up with the steel structure below ground to spread the load before the crane could haul the aluminium roof frame over the 5-storey building.
We are delighted that the recent cranage works went off without any hitches.
