II. Technical Requirements:

Part 1 General:

1. Summary

Furnish all labor, materials, and equipment to confirm the identify location of a water leak and repair service water supply line at Stamford Hurricane Barrier. The general location of the leak has been detected via sound testing, but the exact location of the leak and depth of the pipe in the ground is unknown.

Contractor will be responsible for excavation, removing all damaged pipe, and installing new “in-kind” piping; ensuring connection to existing un-damaged piping is functional and secure. Contractor will re-asphalt roadway.

Contractor will need to coordinate water service interruption/shut off with Aquarian Water Company, notify potentially affected end users, and the Technical Point of Contact prior to beginning project work.

2. Existing Conditions The water line that supplies the Stamford Hurricane Barrier Project Facility runs through the adjacent property (Woodland Cemetery). The water leak in the service supply line for Stamford Hurricane Barrier has been detected in the adjacent property (Woodlawn Cemetery). Woodland Cemetery is where the project repair site is located.

Detection has indicated that the leak is under an asphalt roadway. Exposing the damaged pipe will require cutting, removal of asphalt and trench excavation. Aquarian Water Company has noted the pipe to be a cast iron, 6-inch service water supply line and at approximately 4-5 feet depth. U.S. Army Corps of Engineers drawing STA-1 Sheet 023 (Stamford Hurricane Barrier Utilities East Branch Plans) indicates that the waterline pipe is 6 inches in diameter. Due to its age, no record of prior pipe replacement, and the fact that the material of the pipe at the curb stop shut-off being cast iron, it is an educated assumption that the material of the waterline to be cast iron.

Leak is not affecting water pressure beyond the leak site but is causing groundwater retainment/minor flooding within the Woodland Cemetery. Leak point has been identified by a leak detection service. The attached photos show aerial location map and leak location. In the event that the markings fade, the leak point is located directly in front of the headstone marked “Bella” and roughly 30 feet from the 90 degrees turn in the road.

3. Requests for Information

After contract award requests concerning the work of this project should be directed to the Technical Point of Contact, Park Ranger Ryan Maher at 978-318-8387 or mailto:Ryan.A.Maher@usace.army.mil
