GPF Lewis commissioned LSJ Engineering as the structural steel contractor in a building refurbishment.
We are the appointed structural steel contractor to GPF Lewis, the main contractor refurbishing a building in Mortimer St, W1 (in Mayfair, London’s West End).
This is a very complicated job as the main part of the works is a vertical extension forming a new 5th floor level. The 5th floor of the building is currently the roof of the 4th floor!
We have had to strengthen the existing steel frame at critical points of the current roof level in order to take the new structure’s weight… The total weight of steelwork alone is over 60 tonnes! Some of the new cranked roof beams weigh over 2 tonnes, and the only way to get these to the new level is by lifting them with a mobile crane. GPF Lewis arranged for several weekend road closures to set up a 130 tonne mobile crane and lift the new steelwork into place.
The works are ongoing, and we expect to our contract to be complete before December 2021. We will update you with the finished project in the new year! Here are some of our photos and, excitingly, some drone footage taken by GPF Lewis! You can find their write up of the project here.
