Body

 

Dear Sir:

 

Contract documents and specifications have been prepared for Contract 15-830-3D Replacement of Tailrace Stop Logs, Headrace Gates, and Equipment at Lockport Powerhouse, Stickney Service Area.

 

The purpose of this project is to replace four headrace gates, one set of two headrace stop logs and one set of two tailrace stop logs in Bays 1 and 2, to allow the Lockport Powerhouse to dewater and service the turbines. Periodic maintenance of the turbine is required. However, due to the nonfunctioning head gates and tailrace stop logs, turbine maintenance cannot be performed. This project also includes concrete repair and a new tailrace deck to replace the steel hoist system, improving the overall structural integrity as well as aesthetics of the powerhouse.

 

The project consists of the following:

 

1.   Install one set of two carbon steel stop logs, including guides and bottom sill, to dewater the Head gates area of Bays 1 and 2.

2.   Demolish existing hoist system, supporting steel frame, stop log guides and tailrace stop logs in Bays 1 and 2.

3.   Install a temporary cofferdam system to dewater the tailrace area of Bays 1 and 2.

4.   Install a concrete retaining wall, pier walls and deck over the tailrace area of Bays 1 and 2.

5.   Install one set of two stainless steel tailrace stop logs in Bays 1 and 2.

6.   Regrade the area next to the new concrete retaining wall and install concrete pavement.

7.   Replace existing headrace gates with new stainless steel gates in Bays 1 and 2, including replacement of existing hoist system with four new motor-operated hoist systems.

8.   Repair delaminated and deteriorated concrete at floors, walls and ceilings at headrace and Tailrace areas in Bays 1 and 2, and concrete cracks in the headrace deck over Bays 1 and 2  and surrounding areas.

9.   Provide new lighting at tailrace side.

 

It is estimated that 100 jobs will be created or saved as a result of award of this contract with an estimated 31,500 man-hours of skilled trades utilized.
