Crossrail has awarded its marine transportation contract to a joint venture between Bam Nuttall and Van Oord UK, it announced on Friday.
The contract involves transporting excavated material from Crossrail’s construction to Wallasea Island, Essex to create a new wetlands nature reserve. The contract is worth in the region of £50M.
Crossrail tunnelling will begin at Royal Oak in March with the first ships containing the excavated material arriving at Wallasea Island during summer 2012. The contractor will be responsible for shipping excavated material from Instone Wharf and Barking Riverside in east London and Northfleet, Kent to Wallasea Island.
Up to five ships a day will transport excavated material down the River Thames to Southend–on-Sea. They will then travel north passing Foulness Island before turning west into the River Crouch to reach Wallasea Island. The transfer of excavated material from London and Kent has been planned with the support and assistance of the Port of London Authority and the Crouch Harbour Authority.
Crossrail will provide 4.5M.t of excavated material for the wetlands from the 6M.t it expects to generate during the project.
The winning joint venture beat off competition from Carillion Capital Projects, a Cemex UK Operations/Keltbray joint venture, Lagan Construction, Port of Sheerness and VolkerFitzpatrick. Bam Nuttall is already working on the C806 contract to construct a jetty at Wallasea, which is due to be complete next year.
