FIELD QUALITY CONTROL
Provide labor, equipment, test apparatus and materials required for
preparation and performance of tests and inspections specified to
demonstrate that boilers and auxiliary equipment as installed are in
compliance with contract requirements. During start up and during tests,
ensure that factory trained engineers or technicians employed by the boiler
manufacturer and system suppliers or manufacturers of such components as
the boiler, burner, forced draft fan, feedwater treatment equipment, and
other auxiliary equipment be present, to ensure the proper functioning,
adjustment, and testing of the individual components and systems. Furnish
a detailed written record of test conditions, test procedures, field data,
and start up and operational performance of the entire heating plant to the
