Atkins and Amp will provide design and engineering services on the west section of the Thames Tideway project. The contractors for this section, Bam Nuttall, Morgan Sindall and Balfour Beatty, will tunnel 6km of 7.2m-diameter tunnel from the Acton Storm Tanks at the extreme west of the scheme, to the start of the central section at Carnwath Road. The west section is largely through clay, entering a section of sand at its eastern end. Valued at GBP 416M (USD 602M), it incorporates seven separate work sites along the route. Mobilisation work for the western section begun in September last year with completion scheduled for 2022.
