A JV of Bam Nuttall and Van Oord UK will transport excavated material from the Crossrail sites to Wallasea Island, Essex, UK. The spoil will be used to create a nature reserve for UK wildlife charity Royal Society for the Protection of Birds (RSPB).

Some 4.5Mt of material will be sent to the site from Instone Wharf in up to five ships per day commencing in summer. Tunnelling will begin at the Royal Oak portal in March.

Crossrail programme director, Andy Mitchell, said: “We are delighted to be working in partnership with RSPB to create a major new nature reserve that can be enjoyed for generations to come. At least two-thirds of all Crossrail excavated material will be used to create the wetland at Wallasea Island. With the award of the contract to transport excavated material, Crossrail has now awarded the last remaining major contract that will allow tunnelling to commence in spring 2012.”
