Project anatomy

Contract scope and delivery roles

Client / authority
Icon Water
Delivery parties
Principal construction contractor delivers the works; the reviewed owner updates leave its name unspecified.
Contract route
Icon Water's owner-managed renewal project is under construction. The reviewed community updates describe site delivery rather than a current invitation for bids.
Execution window
The April plan placed pours in July/August/September, June moved them to September/October/November, and the 21 August plan moved them to October/November/December 2026.
Works package
Membrane-bioreactor treatment infrastructure, relocated existing services, bulk excavation and major concrete foundation pours at the operating Lower Molonglo plant.
Marine interfaces
Biological treatment and membrane filtration support discharge quality to the Molonglo River. Existing services and treatment functions must remain coordinated with the new foundation and process work.
Commercial evidence boundary
Repeated changes to the published pour months shift concrete, pump and labour booking dates. The June 950 m3 largest-pour description retains that planning basis; the later plan requires its own confirmed pour release.

Evidence gap

What remains unverified

Outstanding evidence

  • Issued pour sequence and confirmation of completed pours
  • Embedded process interfaces, quality checks and structural release
  • Concrete-delivery access and later membrane/process commissioning
