London utility Thames Water plc has named three U.K. construction teams for up to $3.5 billion of large-diameter tunnel work on its planned mega-sewer project, the 25-km Thames Tideway. Tunneling and separate financing contracts will be awarded this summer, with construction set to start next year.
The tunnel, with work projected to continue through 2023, will be the UK’s largest water-infrastructure project and is expected to create about 4,000 jobs, according to UK Building, a local publication.
