STATEMENT OF WORK

Solicitation Number: W912WJ23Q0005

A. General Description of the Work to be Performed

The general description below is given to indicate the approximate scope of this project only. It does not limit the work required under the project documents.

1. Location and Background. Blackwater Dam is a high hazard potential dam located in the Town of

Webster, New Hampshire. It is located in central New Hampshire, about 15 miles north of the Town of Penacook, New Hampshire. The project consists of a rolled earth fill embankment and concrete non-overflow section, outlet works, and an uncontrolled concrete ogee weir spillway.

The outlet works are incorporated within the spillway and consist of three conduits located through the deep section of the spillway adjacent to the non-overflow section. These three gates are 5’3” high by 3’6” wide rectangular conduit. Access to the gates is by a stairway from the equipment operating room and then through a gallery. Flow through each conduit is controlled by a hydraulically operated gate; additionally each gate is also equipped with a hydraulically operated emergency gate. All gates are operated by hydraulic pumps located in the equipment room. Flow through the conduit passes back into the natural river channel. During normal operation all gates are maintained at a 3-foot opening. Air vents are provided for both the service and emergency gates.

There is an onsite 2-ton monorail hoist located in the operating room that will be available for use;

however, the Contractor shall be required to provide an annual inspection certificate and conduct operational testing in accordance with EM 385-1-1, Section 16, prior to use. Existing anchor points are located above the gate cylinders in the gallery. Similar to the monorail hoist, the Contractor shall be required to conduct operational testing in accordance with EM 385-1-1, Section 16, prior to use.

The gate chamber (gallery) is considered a Non-Permit Required Confined Space. If work execution in the gate chamber creates an atmospheric hazard, the gate chamber will be reclassified as a Permit- Required Confined Space. Any work conducted in a Permit Required Confined Space must be completed in accordance with EM 385-1-1, Section 34 and will require a site-specific Confined Space Entry Plan.

2. Description of Work. The intent of the project is to minimize the ongoing hydraulic fluid slip, which is consequently allowing the operating gates to drift from their specified height. The project includes, but is not limited to, the removal and replacement of the middle piston ring for each gate (three service, three emergency) and replacement with a new hydrolysis-resistant polyurethane piston seal manufactured to operate within the specified hydraulic fluid type, pressure, & temperatures. The Contractor shall note that only one gate at a time may be worked on until the repair work is complete, which shall include standard acceptance testing procedures outlined below under “Sequence of Work and Work Plan”.

The Contractor shall take caution removing the existing piston rings & installing the new seals. If broken during Construction, the Contractor shall be responsible for replacement of the item and any schedule delays that may occur.

The Contractor shall not place the existing gates out of service during the time period of 01 March 2023 through 30 April 2023, inclusive.

No disassembling shall take place until all replacement parts are onsite. Prior to disassembling any of the gate components, the Contractor shall conduct a pre-construction bypass leakage test on each of the gates scheduled to have their piston ring replaced. After reassembling, the Contractor shall conduct a post-construction bypass leakage test. The results of these tests shall be provided to COR and local project personnel. Two bonnet seals will be provided for the Contractor's use during construction. Approximate value of each is $850.

3. Work Site. The site of the work is on a US Army Corps of Engineers Facility, in Webster, New Hampshire. All rules and regulations of the Facility covering general safety, security, site access, sanitary requirements, pollution control and traffic regulations shall be observed by the Contractor.

Information regarding these requirements is outlined below and may be obtained by contacting the Contracting Officer, who will provide such information or assist in obtaining same from appropriate authorities. In the event that there is a need for Government employees to access the gate chamber (gallery) to change gate settings or perform other dam operations functions, (e.g., a flood event occurs, routine gate changes are needed, etc.) during the work of this contract, the Contractor shall have equipment, labor, and materials available to ensure that the Contractor's construction materials and related items are not impeding access and that the gate chamber (gallery) is fully available for these Government operations.

4. Security. The Contractor shall report any vandalism, suspicious activities or devices to the Contracting Officer or local police as soon as possible. The Contracting Officer will notify the Contractor of any heightened security measures and will expect vigilant monitoring of equipment, grounds and security fencing while working.
