PQQ PRINCIPAL CONTRACTOR ACCESS INFRASTRUCTURE AND TIMBER POND INFILL, PEMBROKE DOCK MARINE

The Port of Milford Haven is a trust port and is the UK’s top energy port and Wales’ busiest port handling around 20% of Britain’s seaborne trade in oil and gas. The Port of Milford Haven also owns and operates Pembroke Port and Milford Dock.

The Port of Milford Haven has prepared a Development Plan for the strategic improvement of Pembroke Port, aligning itself with the Swansea Bay City Deal, named Pembroke Dock Marine. This UK and Welsh Government supported project will support the diversification of a strategic UK fossil fuel energy hub into a centre for the renewable energy industry. This will protect both the region and UK in terms of energy security, economy and inclusivity while also working towards achieving decarbonisation targets.

Pembroke Dock Marine comprises four separate but interrelated elements that together will build on an existing energy cluster that has grown around the Pembroke Dock area, in order to develop a world class centre for blue economic development.

The ERDF funded Pembroke Dock Access Infrastructure project is a key part of the Pembroke Marine Project and will specifically include

the construction of the following:

1. A new supersize access slipway,
2. A new workboat berthing facility, and.
3. Infilling of the existing timber pond.

The Principal Contractor appointed must have substantial experience in the successful delivery of a large Civil Engineering Marine Project or Projects with a value in excess of 10 million GBP.

The slipway construction will involve demolition, capital dredging, piling, excavation, the construction of retaining walls and a new supersize concrete slipway together with associated Temporary works, repairs to existing Quay walls, electrical and water distribution, network communications, SCADA and CCTV/security systems and the sequencing of the construction works to minimise disruption to the existing slipway operations.

The new workboat facility will involve modification of the existing Tee-Head building structure and access facility, structural modifications to the existing Ferry Terminal dolphins, new structural steel installations, the provision and fixing of 140m of new pontoon mooring facilities and restraints, together with the installation of electrical and water distribution, network communications, SCADA and CCTV/security systems.

The timber pond infilling involves the deposition into the existing pond of approx. 40,000 m3 and the surcharging of a further (approx.) 15,000 m3 of excavated material with a significant component of rock (to be crushed on site as part of the works). The infill requires to be designed to achieve a controlled settlement with fill laid over a protective sand layer and carefully compacted in layers to accommodate a future construction of a large Fabrication Building over the former pond (not within the scope of the works).

The Timber Pond is a Grade II listed structure and it is anticipated that key features such as the existing limestone retaining wall and sloping stone revetment will be retained and protected or otherwise subject to minimal and localised disturbance through the works where this is unavoidable.

The successful contractor will be appointed as the Principal Contractor and compliance with all H&S Environmental and Ecological legislation, WEFO and SBCD Procurement Procedures and Cross Cutting Themes will be mandatory.

The works will be undertaken under the NEC3 suite of contracts and the successful contractor will be expected to work collaboratively with the Client and its appointed Engineering Design Consultants, Environmental and Ecological Consultants, Project Manager, NEC Supervisor and Quantity Surveyor throughout the project.

Timescales:

It is anticipated the Construction Works contract will start in Q2 2021. However, ECI in the Design Process will be expected in Q1 2021.

Following evaluation of the PQQ returns it is envisaged a minimum number four and maximum number of 6 contractors will be invited to tender (ITT) for stage 2.
