Temporary solid steel fencing was erected around the site to protect the public. Following a CAT scan, all services were terminated before works started, and all
drainage services leaving the site were capped off in the existing manholes. All vehicles entering site were pre-planned and controlled by an appointed banksman. Block paving, voids and drainage covers were protected during the demolition works. A 360-demolition excavator, with demolition attachment, was positioned at the rear of the structure. Banksmen were placed in position and all site staff were in radio contact. As the building was approximately 2 metres from Stafford Street, the demolition work commenced at 18:00hrs. The work was scheduled to take approximately 6 hours through the night.
Using a hydraulic grab attachment, the roof was removed back to the first supporting roof truss, allowing one bay of the roof to be lowered carefully to the ground floor slab. The demolition excavator then loaded the waste generated into a 40-yard bin that was located next to the building. As the demolition progressed, the internal walls were removed. All block work generated from this process was left within the building footprint for the excavator to track on. The external walls of the building were removed last, this, along with a Dust Boss, helped contain any dust generated.
Starting at the edge of the building’s slab and at the furthest point away from the site entrance, an excavator with bucket attachment lifted the slab in large pieces. The floor slab and foundations of the building were removed down to 240mm below existing ground level. Next, the footprint of the building was levelled and tracked in. The area was then covered in tarmac, which was managed by Lawson Group.
