This asbestos was safely removed by Lawson Environmental, in line with HSE rules, guidelines, and recommended procedures.
Due to the location of the neighbouring buildings, hand separation was required next. Following an inspection, a cut line was marked on the site plans. MEWPS were used for access when working at height.
Starting at the top course, the bricks were removed back to the agreed cut line by hand, across the top of the gates. A concrete beam was then carefully lifted down by the excavator.
Using an oxygen propane cutting torch, the roof trusses were cut into one-metre sections. When removing the bottom of the truss, a sit cut was made to both ends of it. One end of the truss, closest to the wall, was levered out; this ensured the truss fell away from the party wall into the drop zone. Starting at point one (shown below), all were cut out. A drop cut was made to the end of the steel, located next to the boundary wall of the building. Starting at the top of the steel beam, a hinge cut was made allowing the steel beam to be lowered towards the ground. The final cut was then made allowing the beam to drop to ground level. As the steelwork was cut out from bay one, work progressed on to bay two.
Then the brick-built gable walls were removed by hand, using a T750 hammer, down to 300mm above the neighbouring wall. An angled coping stone was then installed.
A bay of wall was to remain in place as it could be offering support to the neighbouring wall. The bricks were broken out, course by course, to a width of one metre.
The concrete encasement to the steel beams was also broken out. These were then hot cut using a propane cutting torch to ensure that the bay was separate from the remaining wall.
The mechanical demolition then commenced at the rear of the building. The area marked out in red (below) was the area of demolition that commenced first.
