Project Scope

The scope of works for this project includes:

• Conversion of existing water main to a fire main.
• Installation of new hydrants within the base.
• Replacement of Sewer pit and pumpstation lids.
• Installation of GPT baskets within storm water pits.
• Construction of concrete structures for a new fire tank and pump housing.
• Other associated works.

Key Challenges and Solutions

• Management of contaminated material (PFAS & PASS) required strict testing, onsite storage & drying procedures and transportation to off-site facilities for disposal. The permit and approval process was very time consuming and highly regulated.
• Working within a secure Defence site, with specific ac cess and security requirements.
• Exceptional amount of existing underground services to prove and work around, including sensitive communications cables and equipment, that required a significant amount of Non Destructive Digging (NDD) via Vac Truck.

Achievements

• Operated within a secure Defence site under strict access protocols.
• Managed removal and disposal of PFAS- and PASS contaminated materials.
• Maintained pedestrian and vehicle access to ensure uninterrupted base operations.
• Installed 1,200m of HDPE water/fire mains, including 600m via underground bore.
• Worked collaboratively with CBP, Defence, and contractors to meet program targets and minimise operational impacts.
