**[PART 1 - GENERAL]{.underline}**

1.  **SECTION INCLUDES**

"Work" includes, but is not limited to, materials, workmanship, and
manufacture and fabrication of components. Quality Control is a system
comprised of plans, procedures, and personnel necessary to produce an
end product which complies with the contract requirements.

**1.02 CONTRACTOR RESPONSIBILITIES**

A. The Contractor is responsible for quality control and shall maintain
an adequate inspection system and perform such inspections as will
ensure that the work performed under the contract conforms to contract
requirements. The Contractor shall maintain complete inspection records
and make them available to the Government. All work shall be conducted
under the general direction of the COR and is subject to Government
inspection and test at all places and at all reasonable times before
acceptance to ensure strict compliance with the terms of the contract.
The Contractor shall identify the individual from his organization who
shall be responsible for overall management and quality control, and
have the authority to act in quality control matters for the Contractor.

B. Government inspections and tests are for the sole benefit of the
Government and do not---

> \(1\) Relieve the Contractor of responsibility for providing adequate
> quality control measures;
>
> \(2\) Relieve the Contractor of responsibility for damage to or loss
> of the material before acceptance;
>
> \(3\) Constitute or imply acceptance; or
>
> \(4\) Affect the continuing rights of the Government after acceptance
> of the completed work under paragraph 3.01 E of this section.

C. The presence or absence of a Government inspector does not relieve
the Contractor from any contract requirement, nor is the inspector
authorized to change any term or condition of the specification without
the Contracting Officer's authorization.

**1.03 TESTS**

A. The Contractor shall provide all tests required by these
specifications, unless exempted by the COR.

B. The Contractor shall notify Contracting Officer\'s Representative a
minimum of 2 (two) working days in advance of times when work will be
tested.

**3.01 TESTING**

A. The Contractor shall promptly furnish, at no increase in contract
price, all facilities, labor, and material reasonably needed for
performing such safe and convenient inspections and tests as may be
required by the Contracting Officer. The Government may charge to the
Contractor any additional cost of inspection or test when work is not
ready at the time specified by the Contractor for inspection or test, or
when prior rejection makes re-inspection or re-test necessary. The
Government shall perform all inspections and tests in a manner that will
not unnecessarily delay the work. Special, full size, and performance
tests shall be performed as described in the contract.

B. The Contractor shall, without charge, replace or correct work found
by the Government not to conform to contract requirements, unless in the
public interest the Government consents to accept the work with an
appropriate adjustment in contract price. The Contractor shall promptly
segregate and remove rejected material from the premises.

C. If the Contractor does not promptly replace or correct rejected work,
the Government may:

> \(1\) By contract or otherwise, replace or correct the work and charge
> the cost to the Contractor; or (2) Terminate for default the
> Contractor's right to proceed.

D. If, before acceptance of the entire work, the Government decides to
examine already completed work by removing it or tearing it out, the
Contractor, on request, shall promptly furnish all necessary facilities,
labor, and material. If the work is found to be defective or
nonconforming in any material respect due to the fault of the Contractor
or its subcontractors, the Contractor shall defray the expenses of the
examination and of satisfactory reconstruction. However, if the work is
found to meet contract requirements, the Contracting Officer shall make
an equitable adjustment for the additional services involved in the
examination and reconstruction, including, if completion of the work was
thereby delayed, an extension of time.

E. Unless otherwise specified in the contract, the Government shall
accept, as promptly as practicable after completion and inspection, all
work required by the contract or that portion of the work the
Contracting Officer determines can be accepted separately. Acceptance
shall be final and conclusive except for latent defects, fraud, gross
mistakes amounting to fraud, or the Government's rights under any
warranty or guarantee.

2.  Allow each coat to dry thoroughly before applying succeeding coats.

3.  Make edges of paint adjoining other materials sharp and clean,
    without overlapping.

4.  Make each coat of paint a slightly different shade from preceding
    coat.

5.  Final colors shall match approved samples.

> C. Pigmented (Opaque) Finishes: Completely cover surfaces to provide a
> smooth opaque surface of uniform appearance. Provide a finish free of
> cloudiness, spotting, holidays, laps, brush marks, runs, sags,
> ropiness, or other surface imperfections.

C.  Transparent (Clear) Finishes: Use multiple coats to produce a
    glass-smooth surface film of even luster. Provide a finish free of
    laps, runs, cloudiness, color irregularity, brush marks, orange
    peel, nail holes, or other surface imperfections.

D.  Touch-up and restore finish where damaged. If stain, dirt or
    undercoats show through final coat of paint, correct defects and
    cover with additional coats until coating or paint film is of
    uniform finish, color, appearance and coverage. Give special
    attention to edges, corners, crevices, welds, exposed fasteners and
    similar items to be sure these areas receive dry film thickness
    equivalent to flat surfaces.

E.  Clean off paint spots, oil and other soiling from pre-finished
    surfaces and surfaces with integral finish. Use solvents which will
    not damage finished surface.

                    from the fan as practicable and upstream from
                    restrictions in ducts such as elbows and
                    transitions.

                b.  Measure static pressure directly at the fan outlet
                    or through the flexible connection.

                c.  Measure inlet static pressure of single-inlet fans
                    in the inlet duct as near the fan as possible,
                    upstream from flexible connection and downstream
                    from duct restrictions.

                d.  Measure inlet static pressure of double-inlet fans
                    through the wall of the plenum that houses the fan.

                up an air-handling unit, rooftop unit, and other
                air-handling and -treating equipment.

            3.  Compare design data with installed conditions to
                determine variations in design static pressures versus
                actual static pressures. Compare actual system effect
                factors with calculated system effect factors to
                identify where variations occur. Recommend corrective
                action to align design and actual conditions.

            4.  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, full heating,
                economizer, and any other operating modes to determine
                the maximum required brake horsepower.

        B.  **Adjust volume dampers** for main duct, submain ducts, and
            major branch ducts to indicated airflows within specified
            tolerances.

            1.  Measure static pressure at a point downstream from the
                balancing damper and adjust volume dampers until the
                proper static pressure is achieved.

                a.  Where sufficient space in submain and branch ducts
                    is unavailable for Pitot-tube traverse measurements,
                    measure airflow at terminal outlets and inlets and
                    calculate the total airflow for that zone.

            2.  Remeasure each submain and branch duct after all have
                been adjusted. Continue to adjust submain and branch
                ducts to indicated airflows within specified tolerances.

        C.  **Measure terminal outlets and inlets** without making
            adjustments.

            1.  Measure terminal outlets using a direct-reading hood or
                outlet manufacturer\'s written instructions and
                calculating factors.

        D.  **Adjust terminal outlets and inlets** for each space to
            indicated airflows within specified tolerances of indicated
            values. Make adjustments using volume dampers rather than
            extractors and the dampers at air terminals.

            1.  Adjust each outlet in same room or space to within
                specified tolerances of indicated quantities without
                generating noise levels above the limitations prescribed
                by the Contract Documents.

            2.  Adjust patterns of adjustable outlets for proper
                distribution without drafts.

    12. PROCEDURES FOR VARIABLE-AIR-VOLUME SYSTEMS

        A.  **Compensating for Diversity:** When the total airflow of
            all terminal units is more than the indicated airflow of the
            fan, place a selected number of terminal units at a maximum
            set-point airflow condition until the total airflow of the
            terminal units equals the indicated airflow of the fan.
            Select the reduced airflow terminal units so they are
            distributed evenly among the branch ducts.

        B.  **Pressure-Independent, Variable-Air-Volume Systems:** After
            the fan systems have been adjusted, adjust the
            variable-air-volume systems as follows:

            1.  Set outside-air dampers at minimum, and return- and
                exhaust-air dampers at a position that simulates
                full-cooling load.

            2.  Select the terminal unit that is most critical to the
                supply-fan airflow and static pressure. Measure static
                pressure. Adjust system static pressure so the entering
                static pressure for the critical terminal unit is not
                less than the sum of terminal-unit manufacturer\'s
                recommended minimum inlet static pressure plus the
                static pressure needed to overcome terminal-unit
                discharge system losses.

            3.  Measure total system airflow. Adjust to within indicated
                airflow.

            4.  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 as described for constant-volume air
                systems.

            5.  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 as described for constant-volume air systems.

                a.  If air outlets are out of balance at minimum
                    airflow, report the condition but leave outlets
                    balanced for maximum airflow.

            6.  Remeasure the return airflow to the fan while operating
                at maximum return airflow and minimum outside airflow.
                Adjust the fan and balance the return-air ducts and
                inlets as described for constant-volume air systems.

            7.  Measure static pressure at the most critical terminal
                unit and adjust the static-pressure controller at the
                main supply-air sensing station to ensure that adequate
                static pressure is maintained at the most critical unit.

            8.  Record the final fan performance data.

    13. GENERAL PROCEDURES FOR HYDRONIC SYSTEMS

            4.  Install jacket with 1-1/2-inch (38-mm) laps at
                longitudinal seams and 3-inch- (75-mm-) wide joint
                strips at end joints.

            5.  Seal openings, punctures, and breaks in vapor-retarder
                jackets and exposed insulation with vapor-barrier
                mastic.

        B.  **Where PVC jackets** are indicated, install with 1-inch
            (25-mm) overlap at longitudinal seams and end joints; for
            horizontal applications, install with longitudinal seams
            along top and bottom of tanks and vessels. Seal with
            manufacturer\'s recommended adhesive.

            1.  Apply two continuous beads of adhesive to seams and
                joints, one bead under lap and the finish bead along
                seam and joint edge.

        C.  **Where PVDC jackets** are indicated, install as follows:

            1.  Apply three separate wraps of filament tape per
                insulation section to secure pipe insulation to pipe
                prior to installation of PVDC jacket.

            2.  Wrap factory-presized jackets around individual pipe
                insulation sections with one end overlapping the
                previously installed sheet. Install presized jacket with
                an approximate overlap at butt joint of 2 inches (50 mm)
                over the previous section. Adhere lap seal using
                adhesive or SSL, and then apply 1-1/4 circumferences of
                appropriate PVDC tape around overlapped butt joint.

            3.  Continuous jacket can be spiral wrapped around a length
                of pipe insulation. Apply adhesive or PVDC tape at
                overlapped spiral edge. When electing to use adhesives,
                refer to manufacturer\'s written instructions for
                application of adhesives along this spiral edge to
                maintain a permanent bond.

            4.  Jacket can be wrapped in cigarette fashion along length
                of roll for insulation systems with an outer
                circumference of 33-1/2 inches (850 mm) or less. The
                33-1/2-inch- (850-mm-) circumference limit allows for
                2-inch- (50-mm-) overlap seal. Using the length of roll
                allows for longer sections of jacket to be installed at
                one time. Use adhesive on the lap seal. Visually inspect
                lap seal for \"fishmouthing,\" and use PVDC tape along
                lap seal to secure joint.

            5.  Repair holes or tears in PVDC jacket by placing PVDC
                tape over the hole or tear and wrapping a minimum of
                1-1/4 circumferences to avoid damage to tape edges.

    21. FIELD QUALITY CONTROL

                operation of the control system, the system it serves,
                the service it provides, and its location. For each
                controller, provide space for recording its readout, the
                reading at the controller\'s sensor(s), plus comments.
                Provide space for testing personnel to sign off on each
                data sheet.

            3.  Prepare a preliminary test report. Deficiencies will be

        G.  **If it is determined that the system is constructed
            according to the Contract Documents**, Owner will decide
            whether modifications required to bring the performance of
            the system to the OPR and BoD documents shall be implemented
            or if tests will be accepted as submitted. If corrective
            Work is performed, Owner will decide if tests shall be
            repeated and a revised report submitted.

        E.  **Threaded Joints:** Thread pipe with tapered pipe threads
            according to ASME B1.20.1. Cut threads full and clean using
            sharp dies. Ream threaded pipe ends to remove burrs and
            restore full ID. Join pipe fittings and valves as follows:

            1.  Apply appropriate tape or thread compound to external
                pipe threads unless dry seal threading is specified.

            2.  Damaged Threads: Do not use pipe or pipe fittings with
                threads that are corroded or damaged. Do not use pipe
                sections that have cracked or open welds.

        F.  **Flanged Joints:** Select appropriate gasket material,
            size, type, and thickness for service application. Install
            gasket concentrically positioned. Use suitable lubricants on

        A.  **Install manual air vents** at high points in piping, at
            heat-transfer coils, and elsewhere as required for system
            air venting.

    17. TERMINAL EQUIPMENT CONNECTIONS

        A.  **Sizes for supply and return piping connections** shall be
            the same as or larger than equipment connections.

        B.  **Install control valves** in accessible locations close to
            connected equipment.

    18. FIELD QUALITY CONTROL

        A.  **Prepare hydronic piping** according to ASME B31.9 and as
            follows:

            1.  Leave joints, including welds, uninsulated and exposed
                for examination during test.

            2.  Provide temporary restraints for expansion joints that
                cannot sustain reactions due to test pressure. If
                temporary restraints are impractical, isolate expansion
                joints from testing.

            3.  Flush hydronic piping systems with clean water; then
                remove and clean or replace strainer screens.

            4.  Isolate equipment from piping. If a valve is used to
                isolate equipment, its closure shall be capable of
                sealing against test pressure without damage to valve.
                Install blinds in flanged joints to isolate equipment.

        B.  **Perform the following tests** on hydronic piping:

            1.  Use ambient temperature water as a testing medium unless
                there is risk of damage due to freezing. Another liquid
                that is safe for workers and compatible with piping may
                be used.

            2.  While filling system, use vents installed at high points
                of system to release air. Use drains installed at low
                points for complete draining of test liquid.

            3.  Isolate expansion tanks and determine that hydronic
                system is full of water.

            4.  Subject piping system to hydrostatic test pressure that
                is not less than 1.5 times the system\'s working
                pressure. Test pressure shall not exceed maximum
                pressure for any vessel, pump, valve, or other component
                in system under test. Verify that stress due to pressure
                at bottom of vertical runs does not exceed 90 percent of
                specified minimum yield strength or 1.7 times \"SE\"
                value in Appendix A in ASME B31.9, \"Building Services
                Piping.\"

            5.  After hydrostatic test pressure has been applied for at
                least 10 minutes, examine piping, joints, and
                connections for leakage. Eliminate leaks by tightening,
                repairing, or replacing components, and repeat
                hydrostatic test until there are no leaks.

            6.  Prepare written report of testing.

        C.  **Perform the following** before operating the system:

            1.  Open manual valves fully.

            2.  Inspect pumps for proper rotation.

            3.  Set makeup pressure-reducing valves for required system
                pressure.

            4.  Inspect air vents at high points of system and determine
                if all are installed and operating freely (automatic
                type), or bleed air completely (manual type).

            5.  Set temperature controls so all coils are calling for
                full flow.

            6.  Inspect and set operating temperatures of hydronic
                equipment, such as boilers, chillers, cooling towers, to
                specified values.

            7.  Verify lubrication of motors and bearings.

                complete.

            B.  Keep each wiring device in its package or otherwise
                protected until it is time to connect conductors.

            C.  Do not remove surface protection, such as plastic film
                and smudge covers, until the last possible moment.

            D.  Connect devices to branch circuits using pigtails that
                are not less than 6 inches (152 mm) in length.

            E.  When there is a choice, use side wiring with
                binding-head screw terminals. Wrap solid conductor
                tightly clockwise, 2/3 to 3/4 of the way around terminal
                screw.

            F.  Use a torque screwdriver when a torque is recommended or
                required by the manufacturer.

            G.  When conductors larger than No. 12 AWG are installed on
                15- or 20-A circuits, splice No. 12 AWG pigtails for
                device connections.

            H.  Tighten unused terminal screws on the device.

            I.  When mounting into metal boxes, remove the fiber or
                plastic washers used to hold device mounting screws in
                yokes, allowing metal-to-metal contact.

        E.  Receptacle Orientation:

            A.  Install ground pin of vertically mounted receptacles
                down, and on horizontally mounted receptacles to the
