MECHANICAL / PLUMBING / ELECTRICAL UPGRADES
- Remove existing lift station, discharge piping and cap the vent piping above the ceiling grid. The cap is to be permanent in nature and water tight.
- Install in the sewer soffit ten lengths of four foot Rittling fin tube element, ¾” by 3.25” by 3.25”, 48 aluminum fins to the foot element. Prior to installing coordinate the locations with the TCC PM. Connect the supply and return from this loop to the domestic hot water heater. The piping for the Supply drawings of the proposed piping prior to construction.
All piping below the finish floor can be PEX. Piping entering the mechanical room shall be L copper and anchored to an interior wall using strut, clamps and 10 MIL tape. The circulator will be Grundfos, a Nibco 585 ball valve will be installed above and below the circulator for isolation. Between the bottom isolation valve and the circulator a Nibco ¾” ball valve with integral hose adapter will be required. Components of the utilduct heating system will include but will not be limited to the following; spring checks, isolatable air vents and an expansion tank. Flat line drawings will be required prior to construction of the utilduct heat loop. Provide a lighted, labeled single pole electrical switch and connect to the facilities electrical system.
The temperature in the soffit will be controlled by a remote sensor located in an accessible location, with the circulator and circulator relay located in the mechanical room. All low voltage wiring exposed will be in a conduit. Provide flat line drawings of the control system, with components identified by manufacture to TCC prior to construction.
- Verify that there are no leaks in any of the waste and vent plumbing above and below finish floor. Make repairs as necessary.
- Verify there are no leaks in the domestic water distribution system. Contact the TCC Project Manager for directions on how to proceed.
- Verify that the waste piping is graded properly.
- Extend the waste piping to within 6’ of the exterior of the building. Use a pre foam insulated length of pipe with a heat trace channel to extend the waste piping to the exterior of the building and connect to a new Lifewater duplex lift station. Provide a furnished termination kit that covers all of the pre-installed foam.
- Install an electrical heat trace to the bottom of the sewer main in ¾” PEX from Room 110 to Room 101.
- Install an electrical heat trace to the bottom of the sewer main in ¾” from Room 106 to Room 101
- Install an electrical heat trace in the pre foamed insulated waste line from the exterior and terminating in Room 101.
- Terminate all three heat tapes in a 6” PVC box four feet AFF in Room 101. Exposed heat tapes will be run in conduit. Re use existing circuits to power the heat tapes or run two new circuits from panel box A. All heat tapes will have individual lighted, and labeled switches.
- Insulate all exposed waste lines in the utilduct with 2” wall fiberglass insulation. All edges are to be sealed. Extend the insulation to the connection of the foam insulated main line exiting the building.
- Connect the new lift station to the existing village sewer main using mechanical couplings or electrofusion HDPE fittings, and Arctic Pipe. All vertical to horizontal change in directions will be made with 45 degree fittings. All fittings and joints will be insulated and covered by Arctic Pipe products. Connect the new lift station to the power source from the demoed unit
- Disconnect the existing fuel oil lines after the first valve and at a TCC designated location in the mechanical room. Install a new properly sized one piece copper fuel line from the fuel tank to the TCC designated location and reconnect the fuel line. Secure the new oil line to the exterior of the clinic. Verify over a 24 hour period that the hot air furnace and domestic hot water heater are operating correctly.
- Starting at the isolation valve located in the water plant, remove the existing 1” PEX from the 4” insulated containment pipe that runs from the water plant to the clinic. Remove the existing 1” PEX at the water header located in the clinic.
- Replace the existing line with one (1) 1” PEX line, and one (1) ½” PEX line. Additionally to the 1’ PEX line securely attach an electrical heat trace line. After the isolation valve in the water plant and up stream of the clinic, using a 4” brass nipple, add a 1’ NIBCO brass spring check valve with flow going to the clinic. Connect the 1” PEX to the swing check and approximately one (1) foot downstream, Tee the ½” PEX into the 1“ PEX.
- Reconnect the new 1” PEX to the water header using a new 1” ball valve. Secure the 1” PEX to the wall using strut and clamps. Transition the ½” PEX to ½” L copper one (1) foot AFF, secure the pipe using strut, clamps. And 10 MIL tape. Run the ½ “ L copper to the left hand side of the header, transition back to PEX and make a connection by adding an additional tee and isolation valve. Approximately four (4) AFF add the following; one Nibco 585 sweat ball valve, one Nibco ½” sweat ball valve with integral hose connection, one Grundfos brass circulator, one ½” Nibco 585 sweat ball valve. The circulator is to point with flow down. Adjust the circulator housing so that electrical connections are on top of the circulator
- Terminate the electrical heat trace in a 6” square PVC box, four feet AFF. Supply electrical power from the abandoned circuits in the mechanical room, or run a new circuit from Panel Box A. Provide a single pole lighted, labeled service switch.
- Provide a single pole lighted, labeled switch for the recirculation pump, utilizing existing circuits in the mechanical room or provide a new circuit from Panel Box A.
- Add a six inch takeoff to the main ductwork trunk and run solid 6” round duct to the mechanical room. Install a twenty four inch square diffuser in the ceiling grid with integral damper. Connect the 6” metal duct to the new diffuser with two feet of full size flex duct. No part of the flex duct can be hung or installed as to minimally affect the full size of the duct. Provide a twelve inch by twenty four inch egg shell grate in the ceiling.
- Disconnect electrical service from existing Vacuum pump.
- Reconnect electrical service to new owner provided vacuum pump.
- Remove the existing vacuum pump and set aside, install new owner furnished vacuum pump.
