The contract, for a new quay and breakwater, is being carried out as a Joint Venture, with Westminster Dredging responsible for dredging and rock armour works.
The initial brief was for the design and construction of two lengths of new quay involving suspended decks over rock armour revetments so as not to have a detrimental effect on the wave regime within the harbour. All the initial tender returns were over budget. The Client's Engineer then developed a structural scheme of a composite steel / precast concrete beam / insitu concrete topping suspended deck supported on monopiles cored into bedrock at the sea end and sitting on an insitu concrete bankseat at the shore. The solution, which is more akin to bridge construction than a traditional marine deck, was re-bid by the Joint Venture working with a specialist subcontractor and satisfied the design and budget requirements allowing a price to be agreed and the project to proceed.
RJ McLeod's workscope on this contract comprises the construction of a 120m long, 22m span, open piled quay, with a load capacity of 30kN/m2. A specified load of 500 tonnes at 20m lift radius is required at the heavy lift area along with an enhanced uniform load of 50kN/m2. Also included is a remote mooring dolphin together with associated paving, drainage and services provision.
Principal Elements include:
Marine Piles 19 no. (1.4m dia.) drilled 10m into seabed
Structural steelwork 780T
Reinforced concrete 5,500m3
Precast pre-stressed concrete beams 400 no.
Mechanical and electrical quayside services
Key Issues:
- Works carried out within a busy harbour environment - close liaison with harbour authorities required to ensure minimum disruption to normal habour operations
- Contractor-designed mechanical and electrical services with design development ongoing
