Prior to the strip out works, an R&D asbestos survey was carried out to ascertain if any asbestos containing materials were present. These were safely removed and works progressed to the strip out phase, comprising the removal of all the existing partitioning, ceilings, floor coverings, M&E systems and plant back to the existing core of the structure.
The demolition methodology saw the 45 tonne excavators munch the slabs onto the -oor below, where bobcats periodically dropped material down the internal well hole. Breaking was carried out in a limited manner to reduce the beams into manageable sizes. These were then moved to the West elevation, where the beams were lifted down to the processing area on the ground floor by the crawler crane situated in the Newman Street car park, in order to reduce noise levels.
The third parties in immediate vicinity to the works meant that noise and dust pollution were of a particular concern to Erith. Before the main structural demolition commenced, Erith undertook floor load testing to establish that 45 tonne excavators with cracker attachments could be safely used for the works, which reduced the need for breaking and the resultant noise pollution.
Erith’s Environmental department also undertook dust noise and vibration monitoring throughout the works, based upon safe baseline figures to ensure minimal disruption. Detailed monthly reports were then produced to assess any means of improving the environmental impact of the works, in line with our commitment to continuous improvement.
