676-23-002 Update Electrical Systems Tomah VAMC Statement of Work

I. Background This project will involve several tasks. Several electrical systems are in need of repair and a few tasks related to those systems are in need of attention. In summary:

· Surge protection devices (SPD) for buildings 240A, 400, 401, and 406 main service panels are not working. Those devices need to be replaced as soon as possible,

· Batteries for DC relay for the primary service switchgear are failing in building 428. The battery system needs to be replaced with new AGM batteries,

· Generator Fuel Tanks have surface water leaking into fuel and must be corrected, and

· Heat cable for melting roof snow and ice are needed on buildings 401, 402, 403, 404, 406, 407, and 408.

II. Scope of Work There four tasks in this scope of work. The contractor shall provide all materials, labor, qualified supervision, and equipment to demolish and then install new items outlined in the scope of work, specifications, sketches, descriptions, and follow-up discussions.

Task 1: Replace Surge Protection Device for Building 240A, 400,401, and 406 Main Service Panels The surge protectors are failing or no longer working in these buildings, and they need to be replaced. The surge protectors must be Type 2 per NFPA 70. The existing panels are Square D, QED, Series 2, REV80258-133-06, 60 HZ. Square D must be consulted for the proper size devices. The panel data are:

The surge protectors shall be Square D compatible Surgelogic HL2IMA24C, HL4IMA24C or equal and suitably sized for service.

Task 2: Replace Batteries for DC relay for the Primary Service Switchgear in Building 428 Remove the existing batteries, charger, and storage rack and recycle the batteries in accordance with regulatory requirements. Provide disposal documentation to the COR.

Provide and install new Absorbent Glass Mat (AGM) batteries, compatible charging system, and storage rack sufficient to hold the new equipment, and fits into the available space (6’ Wide X 3’ Deep X 8’ High). The battery system must connect to an existing alarm system that notifies when the relay is activated. Provide commissioning of the battery system. Perform a system test to verify that the new system operates properly. VA shops personnel and COR shall witness the test.

Currently we have 109 cells of 80 A-hr capacity rated at 1.2 V/cell (higher AH to end cell voltage of 1.10V and more to 1.05 V/cell). We will need the same capacity with the AGM battery bank.

Task 3: Mitigate Water Infiltration to Generator Fuel Tanks located at B445, B448 and B424 Tanks 445 and 448 Currently water is infiltrating into the fuel tanks. We want to raise the tank pads and each port hole above the surrounding ground elevation by six inches. The contractor is responsible for measuring the tank pads and port openings for each pad.

Tanks at generator building 445 and 448: We would like to have a six-inch ring added to each tank port (Interstitial Monitoring, Supply & Return Pipes, Vent, and Fill) openings. The rings should have a seal or be welded to prevent water infiltration. A new concrete pad shall be added to the top of the existing pad. Concrete shall be contoured such that the concrete slopes away from the ring of each port to the outer edges of the pad. At the ring, the concrete will be 6-inches thick and taper to about four inches at the edges. This configuration will promote drainage away from the port openings. A layer of tack coat shall be placed between the concrete layers to bond the two slabs together. Include:

· Identification Tags - ports shall be tagged with aluminum name plates embedded in the concrete.

· Paint the fill port as shown in the photos,

· Bollards - An 8-foot tall (4-feet in ground and 4-feet above ground) bollard, 6-inch diameter bollard shall be placed just outside the pad at each corner of the pad. Bollards shall be covered with yellow plastic covers. Holes for the bollards shall be hand dug. The photo shows the typical existing layout.

Tank Pad 445 behind B403 Tank Pad 448 behind B407

Tank 424 (Replace fuel lines and raise pad) Tank at 424 - This tank is in a parking lot. Replace the supply and return pipes because they are deteriorating from exposure to water in the sump. This section of the pad should be dug up as needed to gain access to the pipes for repair. Once the pipes are replaced, the backfill material around the sump should be pea gravel. Patch asphalt around tank pad as needed. Replace demolished concrete pad.

Supply and Return Lines needing replacement.

Additionally, each port on this tank pad will be raised six-inches. This pad will become an island in the parking lot to prevent parking over the tank. The new pad should have a curb that is about 5 inches high. The new concrete at the raised ports will be about six-inches thick. The elevation difference between the ports and the curb edge will provide a small amount of drainage away from the ports. A layer of tack coat shall be placed between the concrete layers to bond the two slabs together. Include:

· Identification Tags - ports shall be tagged with aluminum name plates embedded in the concrete.

· Paint the fill port as shown in the photo,

· Bollards - Six 8-foot tall (4-feet in ground and 4-feet above ground) bollards having a 6-inch diameter. Each bollard shall be covered by a yellow, plastic cover. Each bollard shall be placed just outside the pad at each corner of the pad and at the mid-point of the long side. Bollards shall be hand dug. The photo shows the typical existing layout.

Tank Pad 424 behind B424 (Kitchen Dock) See Appendix B for sketches of existing and proposed conditions.

Task 4: Remove and Replace Snow/Ice Melt Trace on Buildings 401, 402, 403, 404, 406, 407, and 408.

· Remove and dispose of the existing snow/ice melt system on the seven buildings listed.

· Provide and install a new snowmelt system installed along roof edges, valleys, and down spouts in accordance with manufacturer’s recommended layout and installation requirements.

Snow and ice melting systems shall include automatic controls capable of and configured to shut off the systems when the roof temperature is above 45°F and no precipitation is falling, and an automatic control that will allow the system to turn on when the outdoor temperature is 38°F and precipitation is falling so that the potential for snow or ice accumulation is negligible. The specifications (22 05 33 Snow Melt Trace) provide the salient features of the system.

· The snow/icemelt system shall be connected to the building automation system (BAS). The BAS system shall indicate that the snowmelt system is off or on and shall report to the maintenance office in Building 40 through the BAS system. Building 401 has a Siemens BAS system reporting to Metasys. The remaining buildings have a Johnson Control BAS system reporting to Metasys.

A design for a snow/ice melt system was recently completed and installed on Building 400. We are providing this design as an example of our intent for the snow/ice melt system for each of the buildings listed. We are also providing building sketches with rough estimates of wall dimensions. Together, the example design, the building data, and the specifications can be used to assist the contractor in designing the layout plan and estimating quantities of materials. The contractor shall be responsible for determining and confirming final lengths and layouts for the cable system. The sketches and recent design are provided in Appendix C.

The snow/ice melt cable system is being requested as a sole source item. The reason to use the same system is for consistency across the campus. Providing a consistent system on campus reduces maintenance costs for training, number of spare parts being held on-hand, specialty tools for repairs, and better familiarity of the system with maintenance staff. The system being sole sourced is nVent, Raychem Rim2, IceStop Self-Regulating Heating Cable, GM-2X, as provided in the example design in Appendix C. All associated fixtures, controllers, clips and sensors shall be compatible with the system.

The contractor shall be responsible for all new electrical requirements as needed including but not limited to: conduit, breakers, cabling, sensors, mounting brackets, circuits or controls.

III. ADDITIONAL REQUIREMENTS
