Magazine Precinct Goat Island.

Goat Island Magazine Precinct Re-Roofing

 

SCOPE OF WORK

The project scope of works involved protection of building heritage features, roofing, roof plumbing, maintenance and other miscellaneous works.

The works were undertaken on four buildings in the Goat Island Magazine Precinct:

  • The Colonial Magazine Building
  • The Scow Shed
  • The Addition to the Queen’s Magazine
  • The Winch House

The scope of works for each building can be summarised as below:

  • The Colonial Magazine Building: remove gutters and rusted downpipes, secure existing roof sheets, treat rust patches, clear out box gutters, install new guttering, new downpipes, new rainwater head and new sumps.
  • The Scow Shed: Remove all gutters, downpipes and above ground stormwater pipes including downpipe from south east corner. Remove brick piers for stormwater pipes. Remove selected roof sheeting along south wall. Secure existing roof sheeting, replace roof sheets, clean and services roof lights, install new copper gutters, downpipes and stormwater pipe, refix fascia in-situ.
  • The Addition to the Queen’s Magazine: Remove all gutters and rainwater pipes, install new guttering, replace fascias, install downpipes and clean out existing drainage system.
  • The Winch House: secure existing metal roof sheeting, apply external membrane patches and install barge rolls and painting the roof.
  • Sentry Wall: timber frame protection of opening
  • Quarry Face: If required, protect around new roof and guttering works

METHOD

Goat Island is located in the middle of Sydney Harbour and presented a challenging work environment. Logistically, all personnel, materials and equipment needed to be ferried by water taxi to the island at the start and end of the shifts. Thorough planning and ordering of materials and equipment was essential as program budget and timing constraints required that boat trips to and from the island were minimised.

The Goat Island facility was required to remain Operational for the entire time during the Project works for both staff on the Island and various visiting Public Groups.

Roof work by its nature is high risk as it involves work at heights. Murphy’s controlled the risks of working at heights by using a scissor lift and installing temporary height safety systems using static lines and anchor points on the roofs.

All workers using height safety systems and working in safety harnesses were trained by a registered training organisation (RTO) in Working Safely at Heights at AQF level 2. Scissor lift operators had formal training through a one day course with an RTO.

As it was not possible to use a crane due to the location of the buildings, the scissor lift was used for raising and lowering materials to and from the roof.

Quality Management

For all works on the project 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.

Project Control Group meetings were held throughout the project to keep open communication between the DECC and Murphy’s and the construction programme was updated progressively.

Safety Management

All personnel undertook the Murphy’s Site Specific Induction before being allowed to start work on the project. The site was regularly inspected and audited to make sure the safety systems being used on site were effective.

All staff were trained in work activities through SWMS for all tasks and through specific safety training where required such as safe working at heights. Murphy’s Site Manager covered the role of the trained site first aider.

A Project Specific Management Plan was created and used to guide works for the project. Risk assessments were conducted before and during the project and used to formulate the Safe Work Method Statements which covered all high risk work on site.

Environmental Management

Goat Island is located in Sydney Harbour so it was important that the harbour was kept free from pollution and waste materials during the works.

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 the work during the Murphy’s Site Specific Induction.

Heritage features of the buildings were protected including the masonry work of the sentry gate which was protected by the construction of a temporary wooden frame.

Goat Island Magazine Precinct Re-Roofing Project Summary

Benefits offered to Client during Project Works: 

  • Client kept aware of progress of works through effective communication from Murphy’s both on and off-site
  • The normal operations on Goat Island were able to progress including for various stakeholders continue visits to the island
  • Protection of the environment including Sydney Harbour and heritage aspects of the magazine buildings such as the sentry gate
  • No WHS and/or Environmental issues due to effective development and implementation of controls as outlined in the Project Safety Management Plan (PSMP)
  • Project delivered on-budget and on-time

 Due to the high risks associated with the project, including working at heights and working in a harbour side environment, 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 without any issues throughout the course of the works and Department of Climate Change were satisfied with the completed project.
