Council postpones the planned final dredging trip because of storms; rescheduling depends on weather and tides

Project sources

Cornwall Council reported on 23 October that storms had postponed the planned final dredging trip at Truro. Rescheduling depends on suitable weather and tides. Its 11 September update recorded nine completed trips and approximately 1,530 tonnes removed. The capital campaign serves Town Quay, Garras Wharf and Worth's Quay.

Project anatomy

Contract scope and delivery roles

Client / authority
Cornwall Council / Port of Truro Harbour Authority, within Truro Town Deal
Delivery parties
Cormac, named by the owner for the capital-dredging workstream
Contract route
The 11 August owner update identifies Cormac's appointment for capital dredging, without a separate works contract reference, tender route or dredging contract value. Mannin's identification in the harbour notice names the plant, not an additional awarded contracting party.
Execution window
The 23 October update postpones the planned final trip and gives a weather- and tide-dependent rescheduling intention without a fixed replacement date. The August factsheet identified about seven suitable transit and turning opportunities from mid-August through late November; Notice 8 extends the capital programme to December.
Works package
Targeted removal of accumulated mud and silt at three upper quays to restore water depth. The harbour notice sets an upper planned quantity of 5,600 cubic metres. Wider public-realm, pontoon, piling and bridge works are separate waterfront components, not completed by this dredging milestone.
Marine interfaces
Mannin's draft constrains transit above Malpas Point. The dredging cycle combines grab excavation, hopper loading, spring-tide river transit and bottom-door discharge at the designated Falmouth Bay site. The owner factsheet puts transport at approximately twelve nautical miles; it is not a surveyed route plan.
Commercial evidence boundary
The September 1,530-tonne figure is cumulative across nine trips and includes earlier work. The initial 605 tonnes therefore stays within that total. The remaining quantity, actual replacement trip and survey acceptance will determine closeout. The wider Town Deal allocation and planned 5,600 m3 ceiling retain their distinct funding and volume bases.

Storms postpone the planned final dredging trip

Cornwall Council reports that the final operation planned for the weekend has been postponed. A replacement depends on favourable weather and tidal conditions; no fixed date is given.

Source

Nine dredger trips reach approximately 1,530 tonnes

The owner reports nine completed trips, a narrow navigable channel and more space to moor at Town Quay between operations. The total includes the earlier 605-tonne campaign.

Source

Owner reports the first 605 tonnes removed

The 12-17 August campaign removes approximately 605 tonnes of accumulated silt. Further operations depend on suitable tides, with the excavation and offshore disposal cycle continuing.

Evidence gap

What remains unverified

Outstanding evidence

  • Dated replacement for the storm-postponed final trip
  • Remaining excavation and disposal quantities, with mass and volume kept on their stated bases
  • Post-dredging bathymetry, survey datum and harbour acceptance
  • Final disposal monitoring and dredging account
