Frequent project meetings with the client and the subcontractors enabled the Project Manager and Site Manager to communicate effectively with all stakeholders and solve problems as they arose.
To ensure delivery of high quality workmanship, Murphy’s management developed Inspection Test Plans (ITP’s). These procedural documents were issued to and implemented by our site manager to ensure all works completed were in accordance with the project specification and relevant Australian Standards.
A Project Specific Management Plan was created and used to guide works for the project. Risk assessments before and during the project were conducted and all work activities had safe work methods specific to the project developed and delivered through SWMS for all tasks.
As the works were situated in a live Australian Naval base, all project personnel were required to be trained with three levels of induction: Garden Island base induction, Brookfield contractor induction and Murphy’s project site specific induction.
The site was regularly inspected and audited by the Safety Coordinator to ensure the safety systems being used on site were effective.
All waste produced on site was minimised and disposed of using a licensed environmental waste handler as appropriate. All staff were trained in environmental aspects of work during their Brookfield and Murphy’s Site Specific Induction.
Asbestos materials discovered during the works were removed by Murphy’s in-house licenced asbestos removal capability. Asbestos waste was double-wrapped in black plastic, sealed with duct tape and taken for legislatively compliant disposal at the asbestos waste disposal facility at SITA Kemps Creek.
Benefits offered to Client during Project Works;
– Accommodation block was kept operating as normal
– Work delivered with minimum of disruption to residents of the block.
– In-house licenced removal of asbestos materials discovered during the works
– Delivery of the project with no lost time injuries, safety or environmental issues.
– Project delivered on-budget, on-time and with high quality workmanship.
Due to the complexity of the works and the high risks involved, Murphy’s assigned a highly trained and experienced team to the works.
Murphy’s project team all worked together to successfully deliver the project both on and off site. This included the development of all approved documentation and implementation at work-site level.
The project was delivered on-time and to a high standard of workmanship without any issues throughout the course of the works. Brookfield and Defence were very pleased with the completed project.
