Bristol City Council awarded Bullo Limited a GBP 392,500 excluding-VAT works contract to remove accumulated silt within and adjacent to the Floating Harbour. Official contract details fix signature on 24 March 2026 and an original 30 March-26 June contract period. Bristol Harbour Authority's current notice 36/26 schedules dredging at the western end of Baltic Wharf from 10 to 17 August, identifies a floating dredge pipeline and uses the dredger call sign Bullo. No published instrument explains whether the later work falls under a variation, overrun, call-off or follow-on instruction, and completion remains unconfirmed.

Project anatomy

Contract scope and delivery roles

Client / authority
Bristol City Council, acting through Bristol Harbour Authority
Delivery parties
Bullo Limited - supplier named on Harbour Maintenance Dredging contract DN798895, Survey, dredger, pipeline, support-vessel, sediment-handling and disposal lower tiers - not separately identified in the reviewed public record
Contract route
Notice 027070-2026 records a below-threshold limited-competition works contract, tender DN798895, signed 24 March 2026. Bullo Limited is the active supplier at GBP 392,500 excluding VAT and GBP 471,000 including VAT. The contract lists six agreed metrics covering supplier performance, quality and progress, cost and value for money, user experience, risk management, and social value and sustainability.
Execution window
The official contract period runs from 30 March to 26 June 2026. Bristol notice 35/26 scheduled work at western Baltic Wharf from 27 to 31 July, while current notice 36/26 schedules a further approximately seven-day window from 10 to 17 August subject to weather and operational requirements. These later notices establish owner-planned field windows, not a published contractual extension, completed quantity, acceptance or closeout.
Works package
The award description is removal of silt built up within and adjacent to Bristol Floating Harbour by an appropriate method. Current harbour notices add only a western Baltic Wharf location, a dredger, floating pipeline and short operating windows. No public specification located discloses design depth, measured quantity, dredging method across each reach, sediment classification, pipeline discharge point, licensed disposal route or accepted output.
Marine interfaces
Notice 36/26 places a floating dredge pipeline beside the quay wall outside The Cottage Pub and warns that it may enclose the area. It imposes temporary navigation restrictions near Baltic Wharf and Underfall Yard, possible slipway disruption, a prohibition on passing between the dredger and marker pole, safe-speed and lookout duties, and VHF channel 73 contact using call sign Bullo. The work shares a live floating harbour with marina, leisure and water-sports traffic.
Commercial evidence boundary
GBP 392,500 is the signed excluding-VAT contract amount, not a final account or guaranteed physical production value. The notice chain publicly exposes six performance categories but no scored results, certified payments, variation value or accepted final quantity. Work scheduled after 26 June should be treated as a contract-administration question until Bristol publishes the relevant instrument.

Current harbour notice schedules another Baltic Wharf window

Notice 36/26 schedules about seven days at western Baltic Wharf through 17 August, identifies the floating pipeline and Bullo call sign, but does not publish the contractual basis or prove that the scheduled move has occurred.

Source

Earlier Baltic Wharf operating window followed the original contract end

Notice 35/26 scheduled a five-day western Baltic Wharf period after the 26 June contract end. It remains a navigation notice rather than a contract variation or completion record.
