The New York City Dept. of Environmental Protection selected Frontier-Kemper Constructors for a $1.1-billion contract for its Kensico-Eastview Connection Tunnel Project, the contractor’s parent company, Tutor Perini Corp., announced Oct. 23.
The plan calls for construction of a 2-mile-long, 27-ft-dia concrete-lined deep rock tunnel between 400 ft and 500 ft underground to convey drinking water from the Kensico Reservoir to the Catskill/Delaware Ultraviolet Light Disinfection Facility in Mount Pleasant, N.Y. The tunnel is planned for a capacity to carry 2.6 billion gallons of water per day.
