The Mersey Docks and Harbour Company Limited plans to announce a tender for dredging works at the port area.
Officials’ plan is to appoint a contractor to undertake a package of dredging, quay wall construction and infilling works at “Liverpool 2” (Liverpool’s new deep water container terminal), Port of Liverpool, which will be located adjacent to the Royal Seaforth Dock at the Port of Liverpool.
The economic operator will be required to dredge, construct and infill (including compaction of infill material) a quay wall of the following approximate dimensions – 850m length x 30m height.
The quay wall will enclose an area of reclaimed land constituting approximately 2,500,000 m3 of predominantly dredged material. The area of reclaimed land will be surfaced (which may, at the discretion of the contracting entity, be procured under a separate package of works) to form a new deep water container terminal of approximately 22 hectares.
It is likely that the economic operator will take design responsibility for some or all of the Works. The economic operator will be required to dredge a berthing pocket in front of the new quay wall. It is anticipated that the economic operator will be required to remove approximately 1,000,000 m3 of dredged material from the quayside berthing pocket.
The source of the infill material is still to be determined, although it is anticipated that suitable dredged material may be obtained from any or all of the following sources – berth pocket dredge, approach channel dredge and maintenance dredge material obtained from the River Mersey or from commercially available sources.
These following works will also form part of this works package: capping beams, rear crane rail piles and further construction work relating to the provision of drainage and outfall extension.
The value of this project will be between £65,000,000 and £120,000,000.
