The construction of 1.2kms of dual carriageway between Richmond Road and the existing Abell Road at Raine Avenue in Marsden Park. These works are part of the Elara (Marsden Park) residential development.
Orion was engaged by Stockland to provide contract administration services for the construction phase of the project.
Key challenges faced by the development team related to the tight program. Orion worked closely with Stockland, the contractor and relevant consultants to meet the opening date of December 2020.
With extensive remediation works in the first half of 2020 (which was completed under the supervision of an accredited EPA auditor), it was critical that any design or construction issues were resolved with little to no impact on the program. As well as ensuring the works tied in effectively to the adjacent residential subdivisions.
The issues faced included:
- staging of works timeframes,
- working around existing services,
- complying with the State and Local Voluntary Planning Agreements (VPA’s),
- complying with the access deeds for affected landowners,
- addition of traffic signals at the intersection of Glengarrie Road and Northbourne Drive,
- lead-in watermain along the full length of the road extension.
Orion worked closely with Stockland and the project environmental consultant to ensure any contamination onsite was remediated in a safe and efficient manner. It had been identified there was contamination in the western half of the site.
Orion was able to stage the works so that the civil works contractor was able to start the eastern half of the site, including decommissioning and backfill the two existing dams which was on the critical path.
The original program detailed key tasks being run in a linear format. The contractor was able to review their program and split the site into four zones. This allowed multiple crews to operate on different key tasks across the length of the road extension simultaneously.
In relation to compliance with the VPA’s and access deeds, Orion maintained transparent communications with the relevant stakeholders throughout the project. This was achieved through regular meetings onsite and formal notices.
During COVID restrictions, Orion ran outdoor meetings onsite as well as online meetings via MS teams. Maintaining effective communications enabled Orion to streamline the works and minimised adjustment works required by the adjacent residential subdivisions.
With the support of the contractor and relevant consultants, Orion was able to meet the road opening milestone of December 2020. This was not only a benefit to Stockland, but also to Blacktown Council, the Elara community (Stockland), the Horizon Estate community (Rawson), the Fernlea Estate Community (Allam Homes) and future landowners of the subdivisions currently being constructed by Universal Property Group (UPG).
