Project Case Study: Newington Armory – Armory Building Refurbishment and Asbestos Management Program Project No. CAP0472
SCOPE OF WORK
Murphy’s Group Services Pty Ltd was engaged to perform the asbestos removal and metal roof replacement works for the Armory Building Refurbishment – Asbestos Management Program – Buildings 12, 15, 30, 46, 149 & 190 to 194 at Newington Armory Sydney Olympic Park,. The client for the project is Sydney Olympic Park Authority (SOPA).
The project scope of works involved the controlled removal of corrugated asbestos roof sheets, installation of new metal roof sheets, flashings and cappings and other miscellaneous works. All asbestos removal took place using trained asbestos removers operating under licenced asbestos safety and environmental controls.
Newington Armory is the site of the former Royal Australian Naval Armaments Depot (RANAD). The site contains over 100 heritage buildings and is run by SOPA to provide a venue for performing and visual arts. The 52 hectare site of hills and woodlands is open to the public and is a place where the local community can work alongside established artists and international visitors. As such, a major consideration of the project was the protection of the public during the asbestos removal works.
The heritage aspects of the buildings were an important consideration. Murphy’s worked in closely with the client’s project manager and in accordance with the specifications so that the required materials and techniques were used to achieve a finished project in keeping with the original character of the buildings.
Asbestos roof removal and metal roof replacement
The removal of the corrugated asbestos cement sheeting was a major safety concern of the client. Murphy’s was able to allay the client’s fears by demonstrating through past work case studies where our licenced asbestos removal procedures had delivered successful results in similar situations. All personnel employed during the work were fully trained and experienced in asbestos removal, including additional training for asbestos removal supervisors.
A Project Specific Management Plan and Asbestos Removal Control Plan were developed through consultation with project personnel and the client. Situation specific Safe Work Method Statements were developed for each of the different style buildings on the project, which required individual safety control methods.
The safety of the public was paramount during asbestos removal and subsequent re-roofing operations. All work was conducted behind temporary fences and barricades to prevent unauthorised persons inadvertently entering asbestos removal and re-roofing areas where they risked being at danger.
Trained personnel working were protected using P2 masks, type 5 disposable coveralls and gloves when working in the asbestos removal area. Strict personnel decontamination methods were followed and the whole process was overseen by an independent licenced asbestos assessor, monitoring to detect release of asbestos fibres to air and inspecting areas to check all asbestos materials were removed.
Roofing replacement work was carried out by experienced trade qualified metal roofers using Bluescope Lysaght roof sheeting products. Ridge capping and guttering was replaced as part of the works, all materials were in keeping with the originally used materials making sure heritage features were preserved.
PROTECTION OF THE ENVIRONMENT
Protecting the environment surrounding the project buildings was made an absolute priority. The removal process of the asbestos sheeting needed to be performed with no release of asbestos fibres to the surrounds. This was achieved by the spraying down of asbestos cement sheeting with PVA glue solution to fix any loose fibres down to the sheet. The sheets were then removed using by trained and experienced asbestos removers, handling the sheets gently and taking extreme care. Air monitoring sampling was in place at each building throughout the asbestos removal so that the effectiveness of the removal process controls could be measured and reviewed. All readings were taken by NATA accredited hygienists and licence asbestos assessors and were below the detectable limit indicating no release of asbestos fibres to the environment.
The removed asbestos sheets, flashings, cappings and used personal protective equipment were wrapped in two layers of 200 micron plastic, sealed with duct tape and disposed of at a licenced asbestos disposal facility. Receipts were retained as proof of compliant disposal.
Buildings 190-194 and Building 15 were situated directly alongside the Parramatta river. Additional shade cloth and black plastic was used in these areas to ensure no materials or tools risked entering the waterway.
As part of Murphy’s ISO9001 accredited corporate quality management system, inspection and test plans were developed and employed for each building so that hygienist clearances, checks and key workmanship hold points were achieved.
