Harbour construction works

Tender description

Design and build civil engineering marine works to redevelop the St Ola Pier at Scrabster Harbour, Thurso, Scotland. Negotiated procedure with prior call for competition under the Utilities Contracts (Scotland) Regulations 2016 for the procurement of a design and build civil engineering contractor for the St Ola Pier Redevelopment at Scrabster Harbour, Thurso, Scotland. The overall redevelopment involves the reconstruction and redevelopment of the existing St Ola Pier and deepening of the inner and outer berths of the pier to allow larger vessel access. The outer basin will be dredged to ‐8 mCD, with a ‐9 mCD berth pocket adjacent to the pier on the outer berth. An inner berthing pocket will be dredged to ‐7.5 mCD adjacent to the pier on the inner berth. Dredging is mainly sands and gravels. The works required include partial demolition of the existing pier, new and part new pier construction with marine piling, dredged/imported filling, tie rod installation, concrete deck slab and reinforced concrete capping beams as well as dredging and spoil disposal (likely to sea disposal site and partially re‐used in the works). The existing finger pier (outer ≈110 m of pier) shall be maintained as a berthing structure on the inner face only for the 83 m reference vessel. A potable water supply will be provided on the St Ola Pier, along with pipework to support future marine gas oil import and export facilities.
