When Daniel O’Connell’s Sons won the construction contract in 2018 for the $122-million York Street Pump Station and Connecticut River Crossing project in Springfield, Mass., the owner’s designer, Kleinfelder, suggested pipe jacking to launch three new wastewater conveyance pipelines at the pump station that would run under a railroad and flood wall before crossing the river and passing through a levee to the Springfield Water & Sewer Commission treatment facility in Agawam, Mass.

The use of CM at-risk enabled contractors and engineers to quickly deliver a complex project key to solving Atlanta’s drinking-water supply problem.

The four-year project increases storage capacity and replaces two aging concrete water storage tanks and a pump station built in 1963.
