The work was to be carried out in St Petersburg Place adjacent to the famous Whiteleys Shopping
Requirement: Diamond Drilling and Diamond Sawing
The contractor required a T shaped opening through a 400 mm R.C. slab ready to receive a new staircase. The use of percussive breakers was not acceptable due to noise and vibration limitations.
They required sections of concrete that could be man handled and removed from site via a ramp to the ground floor using trolleys
The sections to be removed could weigh no more than 150kg.
Fumes could not be created within the building so all works were carried out using 3 phase and single phase electric tools.
The perimeter of the opening was Diamond Sawn using a 3 phase electric saw to define the edge of the opening and leave a clean cut to full depth.
The opening was then cross cut at 400 mm centres and then repeated in the opposite direction to form sections 400 x 400 ready for the contractor to remove them on trolleys to the ground floor.
The corners of the main opening were diamond drilled to complete the cuts and avoid overcutting into the remaining slab.
Diacutt then used a diamond 3 phase floor saw to cut the slab into 400mm x 400mm squares enabling the client to then lift out the sawn sections ready for disposal.

The client was pleased a clean opening could be formed without upsetting neighbours and ready for the installation of a new staircase with very little additional works.
