New York City’s oldest and largest reservoir is its most vital supplier of drinking water. The Ashokan reservoir is over 190 feet at its deepest point and can hold over 123 billion gallons of water. After the attacks of September 11, 2001, the need for a significant upgrade in Ashokan’s security was brought to light, resulting in permanent closure of the spillway road to vehicular traffic by the city and state. However, this would not be enough to protect NYC’s drinking water.

Conti Federal utilized state-of-the-art technology and methodology to provide Ashokan Reservoir with the security it needed. Working with USACE Omaha’s Protective Design Center on design input and threat assessment, Conti Federal was able to find an appropriate contract value and establish the most time-efficient schedule to make the required security improvements.

This cooperation led to all aspects of construction meeting USACE’s stringent specifications, including a rising bollard system designed to be able to stop a 15,000 pound vehicle traveling at 50 miles per hour. Conti Federal met all deadlines in spite of a major environmental challenge: a protected Eagle Nesting Zone was located along a conduit construction route resulting in strict guidelines and time-sensitive performance of construction activities.

Conti Federal’s proactive, collaborative, problem-solving approach to project execution enabled us to overcome challenges in a timely, cost-effective manner. As a result, the exemplary execution of this project was named Project of the Year by USACE New York in 2007

Key features of the project included:

  • Installed protection and defense structures
  • Constructed two duct banks
  • Performed topographic surveys
  • Constructed entry control points
  • Installed high security K-12-rated security fortification
  • Installed support structures for Closed Circuit Television Cameras
  • Installed electrical systems in PVC ducts
  • Accelerated performance schedule

Named Project of the Year for exemplary execution by USACE New York.
