Mumbai's three-year dredging tender creates three annual acceptance clocks
Mumbai Port's INR 281.70 crore estimate covers three annual campaigns, not one production event. Each cycle has a 24-week completion clock and a 45-day TSHD mobilisation requirement, while the separate 2026-27 budget line, earlier Van Oord contracts, and historical quantities use different accounting and delivery boundaries.

Where USACE dredging records actually appear
USACE dredging records are split between SAM.gov, the Navigation and Civil Works Decision Support Center, district engineering pages, DQM and local sponsor files. A solicitation, bid abstract, award, plant trace, hydrographic survey and acceptance record answer different questions.

Toukley puts the pump station inland and the intake 1 km offshore
Central Coast Council's current Toukley concept keeps the seawater pump station beside the treatment site and sends a 2.4 km microtunnel to an intake about 1 km off Jenny Dixon Beach. Brine would use the existing Norah Head ocean outfall through a short connection.

The CDO pipe pull was scheduled in April and the two desalination pipe pulls in June. Both operation-specific notices have since closed, while the wider three-line notice remains active.
