Kogarah Library is located prominently in Kogarah Town Square, a busy pedestrianised public space in the town centre.
The main purpose of the project was the replacement of the entrance foyer roof, as the existing roof was leaking and defective. Murphy’s was chosen for this work by the client as the company has the necessary expertise and experience in metal roof replacement.
Murphy’s installed a new 370 square metre metal roof in 0.48 Base Metal Thickness (BMT) Trimdek sheeting, in Woodland Grey colour. Flashings and trims were also completed in 0.55BMT Woodland Grey Colorbond steel.
The risks of persons or objects falling from the roof were controlled by erecting edge protection rail around the perimeter of the roof. The roofers worked from completed sections of the roof to replace it progressively, working in harnesses to prevent falls through the open roof space. Murphy’s personnel carrying out the work were trained in Safe Working at Heights, which covers the use of safety harnesses, anchor points and static lines. A scaffold access tower was constructed by licenced scaffolders to provide personnel access to the roof.
Electric scissor and boom lifts were used inside the foyer to replace the ceiling. The electrical cable and equipment was isolated from the power supply while this work was carried out.
The safety of the public was preserved by preventing access to the foyer building during the project. An alternative route into the main library building was maintained throughout the project. Temporary fencing and signage was set-up to secure the work site from unauthorised entry.
Weather forecasts and rain radars were checked so work did not begin if wet weather was expected. The roof replacement was completed in sections, so the roof was never left open to the elements. The roof was left watertight at the end of each shift by replacing the removed section and through use of temporary flashings and tarpaulins.
