Building #99 Tower
Site welfare and parking were located on the concrete slab at the front of the site. Heras fencing was supplied by Lawson Group with debris netting attached and was positioned around the boundary of the site. For safety and security, the access gate always remained closed and locked. The contact phone numbers for site supervisors and managers were displayed for site access.
Building #99 Tower was previously used as a telephone exchange and was built out of brick and timber with a tiled roof. It was sited next to building #114. The lower part of the structure was constructed of a mixture of concrete and brickwork walls.
Internally, this building was a challenge. Soft stripping was needed, and tiles needed to be removed for a bat check before any works could commence – but no bats were found in this building. A CAT scan of the site was carried out by the demolition supervisor who had received the relevant cable detection training.
After completion of the soft strip, demolition could commence. This started on the structure located at the lower level. A Lawson Group owned CAT 336F excavator, fitted with a hydraulic grab attachment, was used to dismantle the concrete and brickwork structure. Starting from the east-facing side of the structure, the walls were carefully removed, leaving the brick-built tower structure.
Next, the wooden and tiled roof of the tower structure was removed, followed by stepping down of the structure’s four walls. This process was repeated until the entire building had been deconstructed. The concrete and brick access bridge was also removed. The wood, brick, concrete and other associated materials were removed and lowered to ground level away from the building. These were processed in accordance with the method statement devised by Lawson Group’s highly qualified project management team.
