Restoring a high-profile Blue Mountains tourist corridor within a World Heritage Area — delivered six weeks ahead of program
- Replacement of a culvert damaged by a one-in-50-year rainfall event and subsequent flooding — restoring Cliff Drive to vehicle access and reopening the Leura Cascades picnic area, six weeks ahead of program and within the $2.8M budget
- Located adjacent to Chelmsford Bridge (Australia’s oldest unreinforced concrete bridge) within the Greater Blue Mountains World Heritage Area — 58 days of vibration monitoring with zero exceedances; weekly upstream/downstream water quality testing with zero adverse results
- Innovative use of High-Density Polystyrene (HDPS) blocks and a large modular shoring system to enable smaller equipment in the constrained site, eliminating vibration risk to sensitive structures and limiting HV powerline outages to planned crane lifts only
- Temporary dam, pump and diversion system installed to protect the waterway during construction; Rescue Plan with harnesses and davit arm for all workers — zero incidents, LTIs or first aid injuries across 7,030 person hours
- Deep cultural engagement with the Gundungurra Aboriginal Heritage Association; 20 staff completed Indigenous heritage ID training before excavation; 100 tree ferns removed and transplanted; 5,000 tonnes of sandstone excavated and backfilled on-site
