The Gregory Hills Drive project consisted of a 5km new dual carriageway from Camden Valley Way to Eaglevale Drive. The road provides a key link between Camden and Campbelltown and provides relief for traffic on Narellan Road.

The Orion team was engaged by Dart West Developments to provide Principal’s Representative services for Stages 5, 6 and 7 of the project, being the construction of the final 2.4km of the dual carriageway and construction of a single span bridge, protection slabs over Jemena and APA Trunk gas mains and 3 new signalised intersections.

Service relocation of existing Telstra, Optus, Jemena and Endeavour Energy overhead HV mains, was required to be done prior to commencement of bulk earthworks. Lengthy lead times on service cutovers meant a staged earthworks approach was required to be undertaken to meet project timelines.
Further to this a disused 1960s gas well was found during the civil works and required extensive consultation with various government entities and specialist contractors to cap and bury the well for road construction.

Orion Consulting through early collaboration with the client helped expedite discussions with network authorities to agree a combined services route to enable early relocation of services.
The gas well was identified early also through consultation with Landowners. Through persistence with relevant government bodies Orion Consulting was able to pull together all interested parties and agree on a safe method to cap and bury the redundant well.

Through its experienced site personnel and proactive ability to manage challenging projects, Orion Consulting was able to ensure the project was delivered ahead of time and on budget.
