Lane secures Seattle ship canal contract

15 October 2019

Washington – Lane, part of the Salini Impregilo Group, announced October 9 it has won a USD 255M contract to build a water storage tunnel to help reduce polluted overflows into the Lake Washington Ship Canal in Washington.

Known as the Ship Canal Water Quality Project –Storage Tunnel project, it entails the construction of a 2.7-mile (4.2km) tunnel that will keep an annual average of more than 75 million gallons (276 million litres) of polluted stormwater and sewage out of the Canal, as well as Salmon Bay and Lake Union. Known as combined sewer overflow (CSO), these untreated waters that spill into the bodies of water near Seattle during heavy rains can make people sick, harm fish, wildlife and the environment.

Work is expected to start in October and be completed in 2022.

Salini Impregilo said it is ready to expand further in the United States, its biggest market by revenue, following the appointment of Mark Schiller as president and chief executive of Lane. With an order backlog at the end of June exceeding USD 4bn and new orders totalling more than USD 800M including contracts that are new or in the process of being finalised, as well as best offers, the group aims to increase its market share with new projects in the transport, water and tunnelling sectors.

In March, Lane won a USD 524M contract to build a basin storage reservoir in Florida to reduce harmful discharges into an estuary. There is also the Three Rivers Protection & Overflow Reduction Tunnel (3RPORT) in Ft. Wayne, Indiana; the Dugway Storage Tunnel in Cleveland, Ohio; and the Anacostia River Tunnel, which along with the Northeast Boundary Tunnel (NEBT) in Washington, D.C., belongs to the city’s major Clean Rivers Project.
