US-based engineering giants CH2M Hill and Jacobs have knocked out rival bid teams from Morgan Sindall, Mace/Atkins and Costain.
The Thames Estuary Phase 1 Programme involves a series of major flood protection works over a ten-year period.
The Environment Agency will pilot new longer term working arrangements to drive down costs and will work with one firm or consortium over the 10-year programme.
This will involve establishing a co-located integrated delivery team of suppliers and Environment Agency staff.
