NSW Public Works (NSWPW), in partnership with Heritage NSW, developed specialised methodologies for assessing 3,670 NPWS assets listed on State, National and World Heritage Registers. As part of the project, NSWPW analysed diverse heritage elements including buildings, works and relics of historical, cultural and architectural significance, adapting processes to account for varying asset types, conditions and locations, while complying with statutory obligations.
A comprehensive model was created for repair estimates, ongoing maintenance costs and a predictive dilapidation model to assess future liabilities.
The final report outlined the methodologies, inspection procedures, bespoke integrity and condition ratings, an inspection checklist framework and maintenance plan.
The project is expected to provide NPWS with a detailed, actionable suite of methods for assessing its heritage asset liabilities.
