Friedman Met with Craig Rebecca of Ameresco at the Facilties & Operations Office located on the Roy C. Ketcham Senior High School Campus, and proceeded to review work performed on various energy conservation measures within the following buildings. This inspection occurred after our scheduled project meeting with Ron Broas, Director of Facilities & Operations of the Wappingers Central School District in which we discussed current status of project and any outstanding issues: Fishkill Elementary School ECM-4 Integrated and New Energy Management System During this inspection, work was estimated to be 50% complete within building. Installation of necessary wiring, conduit, raceways and relays were observed in progress. All work within project design specifications. Reference pictures as appropriate. ECM-7 Infiltration Reductions Work was reportedly 50% complete. Work was inspected and verified. It was observed due to each existing door structure conditions multiple weather stripping materials were installed. Reference pictures as appropriate. All work within project design specifications. ECM 14 Boiler Replacements At the time of this inspection it was observed that two (2) field erected Smith 28HE Series High Efficiency Steam Boilers were installed and set in place on new reinforced concrete housekeeping pads with a Power Flame dual fuel burner, Model C2-GO-20B with remote fuel oil pump connected to each boiler respectively. Integral to the steam system providing heat to the building is the installation of boiler feed tank with three (3) ½ HP centrifugal pumps, and condensate tank with two (2) ½ HP condensate pumps including all appurtenances. Boiler venting was reconnected to existing at points indicated as per the SED approved design (Refer to photos). The insulation of the piping system was currently in progress. During this inspection the steam boilers were operational, but currently not controlled through the building management system. The contractor also provided a separate electrical panel dedicated to all boiler related equipment (burners, remote fuel oil pump, existing duplex fuel oil pump, boiler feed, vacuum, and condensate pumps). The contractor also provided labeling of all electrical conduit runs from the boiler burners back to the dedicated electrical panel to assist in future service as necessary. Proper hangers and supports were installed, and the contractor stated that upon completion of all boiler work all ceiling penetrations where pipe hanger rods were mounted, the ceiling shall be repaired. The steam boilers have been commissioned with training remaining to be administered to the appropriate District s personnel.
