to accommodate actual conditions.
Obtain approval from Architect for adjustment of fan speed higher or lower than
indicated speed. Comply with requirements in HVAC Sections for air-handling units for
adjustment of fans, belts, and pulley sizes to achieve indicated air-handling-unit
performance.
Do not make fan-speed adjustments that result in motor overload. Consult equipment
manufacturers about fan-speed safety factors. Modulate dampers and measure fan-motor
amperage to ensure that no overload will occur. Measure amperage in full-cooling, fullheating, economizer, and any other operating mode to determine the maximum required
brake horsepower.

the critical terminal unit is not less than the sum of the terminal-unit manufacturer's
recommended minimum inlet static pressure plus the static pressure needed to overcome
terminal-unit discharge system losses.
Measure total system airflow. Adjust to within indicated airflow.
Set terminal units at maximum airflow and adjust controller or regulator to deliver the
designed maximum airflow. Use terminal-unit manufacturer's written instructions to
make this adjustment. When total airflow is correct, balance the air outlets downstream
from terminal units the same as described for constant-volume air systems.
Set terminal units at minimum airflow and adjust controller or regulator to deliver the
designed minimum airflow. Check air outlets for a proportional reduction in airflow the
same as described for constant-volume air systems.

The TAB contractor's test and balance engineer shall conduct the inspection in the
presence of Architect.
Architect shall randomly select measurements, documented in the final report, to be
rechecked. Rechecking shall be limited to either 10 percent of the total measurements
recorded or the extent of measurements that can be accomplished in a normal 8-hour
business day.
If rechecks yield measurements that differ from the measurements documented in the
final report by more than the tolerances allowed, the measurements shall be noted as
"FAILED."
If the number of "FAILED" measurements is greater than 10 percent of the total
measurements checked during the final inspection, the testing and balancing shall be
considered incomplete and shall be rejected.
TAB Work will be considered defective if it does not pass final inspections. If TAB Work fails,
proceed as follows:

D.
Verify that balancing devices are marked with final balance position.
Note deviations from the Contract Documents in the final report.
Recheck all measurements and make adjustments. Revise the final report and balancing
device settings to include all changes; resubmit the final report and request a second final
inspection.
If the second final inspection also fails, Owner may contract the services of another TAB
contractor to complete TAB Work according to the Contract Documents and deduct the
cost of the services from the original TAB contractor's final payment.
Prepare test and inspection reports.

DUCT INSTALLATION
A.
Slope: Pitch ducts a minimum slope of 1:300 down toward manholes and handholes and away
from buildings and equipment. Slope ducts from a high point in runs between two manholes to
drain in both directions.
B.
Curves and Bends: Use 5-degree angle couplings for small changes in direction. Use
manufactured long sweep bends with a minimum radius of 48 inches (1220 mm) , both
horizontally and vertically, at other locations, unless otherwise indicated.
C.
Joints: Use solvent-cemented joints in ducts and fittings and make watertight according to
manufacturer's written instructions. Stagger couplings so those of adjacent ducts do not lie in
same plane.
D.
Duct Entrances to Manholes and Concrete and Polymer Concrete Handholes: Use end bells,
spaced approximately 10 inches (250 mm) o.c. for 5-inch (125-mm) ducts, and vary
proportionately for other duct sizes.
1.
2.
Begin change from regular spacing to end-bell spacing 10 feet (3 m) from the end bell
without reducing duct line slope and without forming a trap in the line.
Grout end bells into structure walls from both sides to provide watertight entrances.
E.
Building Wall Penetrations: Make a transition from underground duct to rigid steel conduit at
least 10 feet (3 m) outside the building wall without reducing duct line slope away from the
building, and without forming a trap in the line. Use fittings manufactured for duct-to-conduit
transition. Install conduit penetrations of building walls as specified in Section 260544
"Sleeves and Sleeve Seals for Electrical Raceways and Cabling."
F.
Sealing: Provide temporary closure at terminations of ducts that have cables pulled. Seal spare
ducts at terminations. Use sealing compound and plugs to withstand at least 15-psig (1.03MPa) hydrostatic pressure.
G.
Pulling Cord: Install 100-lbf- (445-N-) test nylon cord in ducts, including spares.
H.
Concrete-Encased Ducts: Support ducts on duct separators.
1.
2.
Separator Installation: Space separators close enough to prevent sagging and deforming
of ducts, with not less than 5 spacers per 20 feet (6 m) of duct. Secure separators to earth
and to ducts to prevent floating during concreting. Stagger separators approximately 6
inches (150 mm) between tiers. Tie entire assembly together using fabric straps; do not
use tie wires or reinforcing steel that may form conductive or magnetic loops around
ducts or duct groups.
Concreting Sequence: Pour each run of envelope between manholes or other
terminations in one continuous operation.
a.
Start at one end and finish at the other, allowing for expansion and contraction of
ducts as their temperature changes during and after the pour. Use expansion
fittings installed according to manufacturer's written recommendations, or use
other specific measures to prevent expansion-contraction damage.

Pouring Concrete: Spade concrete carefully during pours to prevent voids under and
between conduits and at exterior surface of envelope. Do not allow a heavy mass of
concrete to fall directly onto ducts. Use a plank to direct concrete down sides of bank
assembly to trench bottom. Allow concrete to flow to center of bank and rise up in
middle, uniformly filling all open spaces. Do not use power-driven agitating equipment
unless specifically designed for duct-bank application.
Forms: Use walls of trench to form side walls of duct bank where soil is self-supporting
and concrete envelope can be poured without soil inclusions; otherwise, use forms.
Minimum Space between Ducts: 3 inches (75 mm) between ducts and exterior envelope
wall, 2 inches (50 mm) between ducts for like services, and 4 inches (100 mm) between
power and signal ducts.
Depth: Install top of duct bank at least 24 inches (600 mm) below finished grade in areas
not subject to deliberate traffic, and at least 30 inches (750 mm) below finished grade in
deliberate traffic paths for vehicles, unless otherwise indicated.
Stub-Ups: Use manufactured rigid steel conduit elbows for stub-ups at poles and
equipment and at building entrances through the floor.
a.
b.
8.
3.5
If more than one pour is necessary, terminate each pour in a vertical plane and
install 3/4-inch (19-mm) reinforcing rod dowels extending 18 inches (450 mm)
into concrete on both sides of joint near corners of envelope.
Couple steel conduits to ducts with adapters designed for this purpose, and encase
coupling with 3 inches (75 mm) of concrete.
Stub-Ups to Equipment: For equipment mounted on outdoor concrete bases,
extend steel conduit horizontally a minimum of 60 inches (1500 mm) from edge of
base. Install insulated grounding bushings on terminations at equipment.
Warning Tape: Bury warning tape approximately 12 inches (300 mm) above all
concrete-encased ducts and duct banks. Align tape parallel to and within 3 inches (75
mm) of the centerline of duct bank. Provide an additional warning tape for each 12-inch
(300-mm) increment of duct-bank width over a nominal 18 inches (450 mm). Space
additional tapes 12 inches (300 mm) apart, horizontally.
