Met with Craig Rebecca of Ameresco, Robert Colabatistto of Unity Mechanical Corp. 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-5 Steam Trap Replacement

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.
