Challenges

Site access constraints

With multiple contractors working on site, Vaughan navigated varied site access constraints through effective coordination and clear communication with stakeholders, fostering positive relationships and ensuring the project remained on schedule.

Undisturbed public operations

The Penrith Cricket Club grounds consists of three ovals and is located adjecent to the Penrith Stadium, it was critical that the ground and public space remained operational throughout construction. Vaughan ensured that all works were completed safely with appropriate cordoning measures.

Archaeological Requirements 

Heritage NSW requested that archaeological trial holes be dug prior to construction to ensure that it was not an area of archaeological significance. An investigation was undertaken in collaboration with our licenced asbestos assessor and specialist heritage consultant, to ensure the area did not present any contamination or heritage significance. Seven test holes were investigated with no notable findings.
