The 7.2 km long walking trail between Marino and Hallett Cove was constructed in stages between 1996 and 2006 and has not been regularly maintained. It comprises gravel paths, a network of timber stairs spanning gullies and boardwalks fencing, seats, viewing platforms and stormwater drainage assets.
Tonkin Consulting prepared an asset management plan, detailed structural inspection and defect and safety audit to ensure these public assets were kept safe and maintained.
The path and structures asset management plan included an original condition assessment, valuations, options for improving accessibility, a renewal/ maintenance plan, and annual maintenance program with expenditure. It also identified additional funding for maintenance.
Stairs and elevated timber structures were thoroughly inspected for safety and to identify any structural defects. Works like loose nails, broken steps, split timbers and damaged stringers were flagged for immediate attention with estimated costs for repair. A safety audit considered trail usage, identified major safety concerns with structures (highest risk items being the stairs and balustrades) and recommended improvements and treatments.
A defect and safety report, detailed asset location register and maintenance schedule was prepared for consistent reporting. Tonkin Consulting also prepared an estimated remaining life and replacement value.
The safety audit was overseen by a qualified building certifier applying a risk based approach based on Australian Standards and the Building Code of Australia. The asset management plan was based on the IPWEA / NAMS guidelines
