CONTROLS. Control system shall be [pneumatic] [DDC] [or] [electric]. Provide all
devices required, including air compressors, refrigerated dryers, current transducers,
transformers, thermostats, sensors, controllers, actuators, control valves, dampers, transmitters,
flow meters, etc., to provide a complete and operable system. All thermostats for systems that
provide both heating and cooling shall have a deadband of 2.8 degrees C [5 degrees F]. All
equipment and systems shall be automatically controlled [and monitored] by the control system.
[The control system shall tie into the existing [EMCS] [UMCS] system.] [A description of the
existing system shall be provided by the design agent.] Control system instructions shall be
provided for each system. The instructions shall consist of half-size laminated drawings and
shall include the control system schematic, equipment schedule, ladder diagram, sequence of
operation, panel arrangement drawings, wiring diagram, and valve and damper schedules.

TESTING, ADJUSTING AND BALANCING. Testing, adjusting and balancing of
each system shall be the Contractor's responsibility. Testing and balancing of air and hydronic
suystems shall be accomplished by a firm certified for testing and balancing by the Associated
Air Balance Council (AABC) or National Environmental Balancing Bureau (NEBB). Prior to
testing, adjusting, and balancing, the Contractor shall verify that the systems have been
properly installed and are operating as specified. Testing of individual items of equipment shall
be performed by a person authorized to perform such tesing and startup by the equipment
manufacturer. The contractor shall correct all systems and equipment not found in compliance,
and shall be responsible for all labor and materials required for this effort. AABC MN-1,
NEBB-01, SMACNA-07 or ASHRAE 111 shall be used as the standard for providing testing of
air and water systems. The selected standard shall be used throughout the entire project. All
recommendations and suggested practices contained in the selected standard shall be
considered mandatory. Instrumentation accuracy shall be in accordance with selected standard.
10-15.2
Piping systems. Each piping system including pipe, valves, fittings and equipment
shall be hydrostatically tested and proved tight at a pressure of 1-1/2 times the design working
pressure, but not less than 699 kPa [100 psi] for a period of not less than two hours with no
appreciable loss in pressure. Piping shall not be insulated until testing is completed and
acceptable. Upon completion of installation and prior to startup, each hydronic system shall be
balanced. All balancing data, including deficiencies encountered and corrective action taken,
shall be recorded. Following final acceptance of certified reports by the Contracting Officer, the
setting of all HVAC adjustment devices shall be permanently marked by the Contractor's
balancing engineer so that adjustment can be restored if disturbed at any time.
10-15.3
Air systems. Following adjusting and balancing, duct pressure testing of air systems
shall be performed on 10 percent of the systems which have been randomly selected by the
Contracting Officer. No additional testing will be required if at least 90 percent of the tested
systems pass the air leakage test requirements. If less than 90 percent of the tested systems
pass the air leakage test, an additional 10 percent of the systems shall be tested. This process
shall continue until 90 percent of the total number of tested systems pass. Where specific
systems require special or additional procedures for testing, such procedures shall be in
accordance with the standard selected. All data, including deficiencies encountered and
corrective action taken, shall be recorded. Following final acceptance of certified reports by the
Contracting Officer, the setting of all HVAC adjustment devices shall be permanently marked by
the Contractor's balancing engineer so that adjustment can be restored if disturbed at any time.
10-15.4
Equipment. Each item of central operating equipment provided, including boilers, [air
handling units,] [
] and chillers shall be tested in accordance with the equipment
manufacturer's standard testing procedures. A factory representative shall be present for the
SOW-145
