Bristol's signed Bullo contract is GBP 392,500 excluding VAT, GBP 471,000 including VAT, for 30 March to 26 June 2026. Notices 35/26 and 36/26, consulted in August, scheduled Baltic Wharf windows in late July and on 10-17 August with a floating pipeline and Bullo call sign. Both are absent from the current October listing. A post-term instruction, actual production and accepted quantities and depths remain unconfirmed.

Historical navigation windows follow the signed period

Bullo's UK7 records the signed value, original period and six performance metrics. The August source record cites later Baltic Wharf windows, now absent from the October index. Company pages describe corporate capability and fleet; project-specific instructions, accepted output and closeout remain outstanding.

Baltic Wharf pipeline and navigation interfaces

The historical notices describe an operating interface at western Baltic Wharf: a dredger, floating pipeline, marker pole, slipway disruption, VHF channel 73 and restricted navigation near Underfall Yard. The later scheduled windows and the original signed term have different dates. The controlling instruction or variation is needed to connect that work to the contract.

Evidence conclusion

Contract instruction, survey acceptance and closeout

The original 30 March-26 June term and six agreed performance metrics come from Find a Tender. The August source record cites 35/26 for 27-31 July and 36/26 for 10-17 August, subject to weather and operating requirements. The October index omits both; original full-text recovery remains outstanding. The date of their removal, actual work dates, post-term contractual basis, accepted depth and quantity, sediment route, plant and lower-tier assignments, scored performance, final account and handover remain unconfirmed.

Outstanding evidence

  • Contract variation, extension, call-off or follow-on instruction after 26 June

  • Dredging method, pipeline destination and licensed sediment route
