Scope of works
The project scope of works included:-
- Site Establishment and provision of safe access for Murphy's personnel and pool personnel
- Removal and storage of 22 tonnes of pebbles from the roof
- Repair works to the existing membrane on the roof
- Removal and storage of pebbles on the decorative pebble beds
- Creation of falls and water proofing to the decorative pebble beds
- Removal and reinstatement of capping, external painting works to all existing steel beams, various waterproofing works to junctions, beams and other areas, removal and reinstatement of timber decking and other miscellaneous works as required.
The pool is a prestigious facility in a sensitive, high profile location situated on Sydney Harbour. For this reason the highest quality materials were specified and top quality workmanship required. Murphy’s achieved this by allocating trade qualified specialists for specific tasks.
The highest risk task in the project was to remove the existing pebbles from the roof and store them on-site. Firstly, Murphy’s was required to establish safe access to the roof and erect roof perimeter handrails to ensure project personnel were not at risk from falling from the edge of the roof. We achieved this through the fixing of custom handrails and a tube and fit scaffold access tower.
Once safe access to the roof had been established, the pebbles on the roof were shovelled into bags spread out evenly over the roof the ensure point overloading did not occur. Each bag was then craned from the roof and stored in a specified laydown area. Due to the surrounding environment of the pool facility being so busy, Murphy’s established appropriate traffic management and exclusion zones around the crane whilst the task was carried out succesfully.
Safe access was required to be in place for the duration of project works including painting, water proofing and the installation of new perimeter drip trims.
Benefits to the Client during Works
- No OHS and/or Environmental issues with the implementation of good controls
- Safe access maintained for general public and pool staff still using the pool buildings facilitys
- Ensure safe access for persons walking past the pool facility was maintained with good management
- Continual communication and consultative programming of the works on a daily basis with the client to ensure awareness of works progression
- Project was completed without any OHS, Quality and/or Environmental issues with sound development and implementation of Project Specific Management Plan (PSMP)
Project Summary
The reason the project was undertaken was to ensure the water tightness of the entire building. It had been identified in a diagnostic report by the engineer that areas of the building were permitting the ingress of water. The purpose of the project was to fix these identified areas in accordance with the project engineers specification.
During the course of the works, it was found that other areas not in the initial report required rectification. Murphy’s assisted the client with design to rectify these areas and carried out works as requested.
The Pool facility regularly shuts down for one month of the year each August. This time was the obvious opportunity window Murphy’s to complete the project works. Murphy’s allocated two site managers to ensure there was plentiful on-site leadership for the project works to be completed within the deadline. With the implementation of appropriate controls and the allocation of necessary resources the project was completed by the completion due date.
The high risk nature of the project (both Environmental and Safety aspects) meant that the development and implementation of the Project Specific Management Plan (PSMP) was critical. Murphy’s developed the PSMP and consulted with project personnel on a daily basis.
The painting upgrade works included the application of a 3 part painting system. The painting works were carried out to all structural elements of the building, both internally and externally. For this reason the works were coordinated with relevant persons from the pool management. Murphy’s ensured all manufacturers instructions were followed to obtain warranties.
All works on the project were monitored constantly and executed by experienced trade qualified persons. Murphy’s ensured that the quality of the works was to very high standards, with the development and implementation of Inspection Test Plans (ITPs) in accordance with the project specifications and relevant Australian Standards.
With effective communication through out the project and well thought through work methods, Murphy’s completed the project without any OHS & Environmental issues and to an extremely high quality.
