HERITAGE ASSET PROTECTION DURING SENSITIVE ROAD REHABILITATION WORK
The Project
2021 saw severe weather impacts on the UNESCO World Heritage Site – The Jenolan Caves. The Roadways (Jenolan Caves Road at Hampton, 2 Mile & 5 Mile) were faced with landslips, broken rails and even floods. Safety concerned prompted closing access to these roads, and repair works were undertaken in the years after. McIlwain Civil Engineering engaged UBY Group to deliver vibration monitoring services at the Jenolan Caves Heritage Hotel during drilling, excavation and soil nailing works associated with the 2 Mile Hill project. Given the sensitive heritage environment, reliable monitoring and responsive coordination were critical to ensuring construction activities could proceed safely and compliantly.

Project: 2 Mile Hill – Jenolan Caves Heritage Hotel
Location: Jenolan Caves, New South Wales, Australia
UBY Services: Vibration Monitoring
Project Duration: 3 months
Construction Activities: Drilling, excavation and soil nailing works to rebuild roads
Environment: Live, heritage-listed structure
The Challenge
The project involved carrying out drilling and excavation works in close proximity to a heritage-listed structure which is over a 100 years old, where even minor vibration impacts could pose a risk to the asset.
Key challenges included:
- Working within a highly sensitive heritage environment
- Ensuring real-time visibility of vibration levels during construction
- Maintaining regulatory compliance while keeping the project on programme
- Minimising disruption to the site and surrounding operations

- Proactive coordination of site access and setup, enabling seamless integration with ongoing work.
- An experienced team with a proven understanding of operating in heritage-sensitive environments
Results
The vibration monitoring near heritage structure delivered measurable value to the project by:
- Continuous monitoring by the UBY team kept the project under constant control
- Any potential alerts were identified well before their exceedance
- The contractor team remained within acceptable limits, posing no risks to the Jenolan Caves House
With the quality & clarity of monitoring service provided by UBY, McIlwain team could continue the project without any interruptions.
