“Engineering Aspects of the Construction of NYC Water Tunnel No. 3”

Ted Dowey, P.E., Project Manager, NYC Dept of Environmental Protection

Deep beneath Manhattan, nine miles (14.5 km) of tunnel have been excavated and ten shafts have been constructed, completing the excavation for New York City’s Water Tunnel No. 3. The contract for $670 million was executed by the joint contracting venture of Schiavone Shea Frontier-Kemper. The tunnel, 12’ 6” (3.8 m) in diameter and 500 plus feet (152 m) deep, was driven by a tunnel boring machine. Nine new shafts averaging 530 feet (161 m) deep were constructed in a variety of geologic and urban environments using blasting, raise boring, soil mix walls, ground freezing, pile driving, and soldier piles and lagging. The engineering components and production rates for the tunnel boring machine and raise boring machines are presented. Blasting techniques in the shaft (subject to vibration and noise restrictions) are presented. The structure of the combined DEP and consultant staff is discussed.

Mr. Ted Dowey, is an Executive Construction Manager for the New York City Department of Environmental Protection (DEP). He is directing the construction management of the Manhattan Tunnel contract. This is a $670 million project building nine miles of tunnel and ten deep shafts with a staff of over 30 DEP and consultant engineers, geologists, and inspectors. Mr. Dowey has been involved with the construction of New York City’s Third Water Tunnel for over 20 years, starting as a geologist, becoming a construction inspector, resident engineer, and finally the executive construction manager directing all aspects of the construction management for the project. Mr. Dowey also directs the geotechnical program which provides geotechnical information for the tunnel and shaft designers and provides a basis for contractor bids on the tunnel contracts. Mr. Dowey conducts community outreach at construction locations, informing and coordinating with Community Boards, elected officials, residential and commercial entities, and neighborhood organizations. Mr. Dowey has a BA in Geology from Columbia College, an MS in Mining Engineering from the Columbia School of Engineering and Applied Sciences and a New York State Professional Engineer License. Mr. Dowey has published three articles for the Rapid Excavation and Tunneling Conference and has had three tunnel photography exhibits.
