Complex asbestos and reinstatement works at steel fabrication workshop.
McMahon Services was engaged by one of Australia’s largest steel distributors and manufacturers to undertake asbestos removal and reinstatement works at their steel fabrication workshops in O’Sullivan’s Beach, South Australia.
The complex project required the removal of over 9,000 square meters of asbestos roofing, box guttering, flashings and 400 square meters of asbestos vent ridges.
One of the major challenges was to complete the removal and reinstatement works within a four week period during the scheduled shutdown over the Christmas period. The project called for an in-house team of asbestos removal technicians, roofers, crane drivers and riggers with over 60 personnel on site at the project’s peak.
The team worked 12 hour days, seven days a week over the month of December. Working close to the coastline, the team was faced with days of high winds as well as a small heat wave only taking breaks for Christmas Day and Boxing Day, totaling approximately 12,600 man hours.
Complete internals of the workshop were covered in plastic before asbestos removal works commenced, and extensive decontamination works were also conducted to ensure there were no traces of Asbestos at handover. Specialist HEPA vacuums were used to clean all internal surfaces, purlins, trusses, girts, wall cladding, overhead cranes and structures.
All manufacturing plant and equipment housed within the workshop were also decontaminated. An Industrial Vacuum Recovery Unit was then used to high pressure wash the machinery and the waste water disposed of in line with EPA requirements.
Asbestos roof material was replaced with concealed fixed-steel roofing, along with foil blanket insulation supported by safety mesh. In addition to the new roof, skylight sheeting and finishes such as new downpipes, gutters, safe access walk ways, static lines and ladder access to suit the roofing profile were also installed.
An extensive fleet of equipment was mobilised to site for the duration of the project including four cranes ranging from 25-250 tones and 23 Elevated Working Platforms. Given the large scope of the project and asbestos removal works required, community and stakeholder engagement with neighboring businesses was critical to address concerns and to detail the removal process and safe work methods. Some 80 residents surrounding the site were also notified by hand delivered mail explaining the project details.
