A design and build civil engineer is sought for the redevelopment of St Ola Pier redevelopment in Scotland.
The £17M contract advertised by Scrabster Harbour Trust in Thurso, includes dredging of the inner and outer berths at the harbour, reconstruction of marine piling and land reclamation.
The tender announcement follows on from RPS’ appointment to undertake design on the project in June last year.
Works also include partial demolition of the existing pier, reconstruction 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 outer berth at the harbour will need to be dredged to -9mCD and the inner berth to -7.5mCD - overall dredging is around 150,000m³ of mainly sands and gravels.
Land reclamation and rock armoured revetment construction are also proposed to support the pier development and improve queuing and access to the ferry to Orkney. This reclamation may use imported rockfill or reused dredged material, the notice states.
In addition a potable water supply and a fuel supply will be re-routed from an existing pier in a dredged trench in the seabed around the harbour to the reconstructed St Ola Pier.
The Harbour Trust anticipate that three firms will bid, and it is expected that work will begin in December this year and be completed by March 2021.
