Contractor is responsible for verification of all details, measurement, etc., prior to ordering materials and execution of work.

2. Replace facilities’ single 300-gallon hot water heater in Lodging Building 300 with a new high efficiency hot water heating system that will meet the same level of performance of first hour rating capacity while exceeding the current hot water storage.

Existing conditions: A.O. Smith Model #BTP300 / 1,000,000 BTU/Hr, 300 gallon, natural gas fired hot water heater.

Total Hot water system Objective:

2.1.Meet performance requirements in-kind to existing, including hot water system equivalent to 1,000,000 BTU/Hr.

2.2. Exceed existing storage capacity of 300 to >300-gallons and 970 Gal/Hr. recovery capacity temperature rise at 100⁰F.

3. Implement a design and schedule that limits facility down time and hot water use to occupants. This can be achieved by notifying COR and/or facility manager of hot water

914 MSG / CEC

Niagara Falls Air Reserve Station

2405 Franklin Drive

Niagara Falls, New York 14304-5063 disconnect and with preconstruction planning and preparedness prior to demolition of primary (existing) unit. Provide limited engineering services as necessary to support design of the replacement system.

4. Selectively demolish, remove, and properly dispose of the existing hot water heater and associated components.

4.1. Be aware that removal and replacement of hot water tanks will require some level of dismantling and reassembly of existing mechanical room equipment to safely complete objectives.

5. Provide and install any and all necessary ancillary components such as piping, joints, valves, pipe hangars, pipe insulation, etc. and modify/add (as required) any existing gas or hot/cold water piping, venting, condensate piping, electrical or other components as needed to facilitate a complete and proper installation of the new hot water heaters.

6. Relief valves. No valves shall be installed between a relief valve and its water heater or storage tank. The P&T relief valve shall be installed where the valve actuator comes in contact with the hottest water in the heater. Whenever possible, the relief valve shall be installed directly in a tapping in the tank or heater; otherwise, the P&T valve shall be installed in the hot-water outlet piping. A vacuum relief valve shall be provided on the cold water supply line to the hot-water storage tank or water heater and mounted above and within 6 inches above the top of the tank or water heater.

7. Installation. Installation shall conform to NFPA 54. Storage water heaters that are not equipped with integral heat traps and having vertical pipe risers shall be installed with heat traps directly on both the inlet and outlet. Circulating systems need not have heat traps installed. An acceptable heat trap may be a piping arrangement such as elbows connected so that the inlet and outlet piping make vertically upward runs of not less than 24 inches just before turning downward or directly horizontal into the water heater's inlet and outlet fittings.

Commercially available heat traps, specifically designed by the manufacturer for the purpose of effectively restricting the natural tendency of hot water to rise through vertical inlet and outlet piping during standby periods may also be approved.

7.1. This design will have a second hot water tank installed in-line with the hot water heating system. Contractor will plan tank sizes that best utilizes the space and not obstruct existing controls and equipment. The system will achieve facility hot water demands and temperature recovery requirements.

7.2. Each hot water tank will reside on a concrete pad. (4-inch-thick construction). The footprint of each hot water tank is limited to the space constraints provided within the mechanical room.

7.3. In addition, this project will include replacement of an expansion tank, circulation pump, venting, condensate piping, and piping (as defined in No.5 above). Modify and add electrical circuits as needed to meet the requirements of the hot water heating system.

7.4. Finishes: Contractor will address all ancillary components with proper pipe insulation, labels/warnings and painted surfaces to match existing hot water heating system.

8. Provide an operation and maintenance training session with Base staff at system turn over.

Submit copies of all operation and maintenance manuals, warranties, and list of spare parts.

9. Environmental Protection

9.1. Collect, containerize and properly dispose of all waste materials generated from the project off base, including but not limited to: existing heaters, piping, insulation.

9.2. Ensure the work area is clean and free of all debris at the end of each work day.

9.3. The Contractor shall be responsible for characterization, storage, describing, packaging, labeling, marking, and placarding of wastes related to the removal of the joint sealant to include waste sealant and sand blasting material/media at a minimum; blasting media used on the installation cannot be recycled, it must be disposed of. The Contractor shall characterize the waste as required by the disposal facility. Any analytical results shall be forwarded to 914 MSG/CEV for review and approval. Waste shall not leave the base until approval has been obtained from 914

MSG/CEV. It is anticipated the waste will be characterized as non-hazardous. The

Contractor shall manifest, pack, ship and dispose of all waste in compliance with

Federal, State and local laws and regulations.

9.4. Comply with Base standards for storage of hazardous materials such as sealant and gasoline and wastes. Bulk materials and wastes must be secured and stored under cover. Maintain supplies on hand to contain and cleanup any spills generated by the Contractor’s activities. Report any spills to the Base Environmental office in accordance with Base’s SPCC Plan.

9.5. Contractor is to recycle or divert as much waste as practical.

9.6. Quarterly the Contractor must submit the Waste / Recycle Materials Log for

Contractors with a list of materials disposed and recycled.

9.7. Green Purchasing: The Contractor shall comply with the Green Purchasing requirements of the contract. Known / possible EPA Comprehensive Procurement

Guideline, USDA Biobased, Green Seal Energy Star, etc., items. Recycled materials must be used to fullest extent in accordance with Executive Order 13101.

The EPA web-site, http://www.epa.gov/cpg, can be accessed for further instruction on what is an EPA-designated material.

9.8. An asbestos and Lead based paint (LBP) survey was not completed in any of the mentioned work areas. The contractor shall immediately contact 914 MSG/CEV and 914 MSG/SGPB prior to disturbance if any asbestos and LBP containing materials are suspected.

10. Submittals

10.1. In addition to any submittals required, provide the following project specific submittals for government review and approval prior to initiating work:

10.1.1. Work Schedule

10.1.2. Waste Logs
