                       d. Day tank high-level switch
                       e. All switches are normally closed with the day tank empty.
               B. Call for Fuel
                   1) A call for fuel is triggered by the day tank level switch:
                       a. The lead supply pump will start at day tank pump on level.
                       b. The normally closed supply solenoid valve at the main tank will be
                          energized and open.
                       c. The normally closed solenoid valve at the day tank will energize and
                          open.
                       d. Pump will stop at day tank pump orr level
               C. Low Level Alarm (Startup)
                   1) The day tank low-level alarm will be energized on system start-up and the
                      alarm bell will sound. The operator must depress the alarm silence
                      pushbutton on the touch screen to reset the low-level alarm circuit. After
                      the supply pump automatically fills the day tank above the pump off level
                      switch, press the reset button on the touch screen to reset the low level
                      alarm circuit.
               D. High Level Alarm
                   1) When the oil level in the day tank rises to the “high level alarm” setting,
                      the control system will stop the supply pump(s), close the supply solenoid
                      valve, energize the high level alarm light and sound the alarm bell. The
                      MCP will energize the return pump and the pump will continue to operate
                      until the oil level falls below the “pump off” setting. When the oil level
                      falls below the “high level alarm” setting, the high level alarm will
                      automatically reset.
               E. Day Tank Vent Alarm
                   1) In the day tank a vent leak detector will detect overflow fuel in the
                      operating vent. If the leak detector switch is opened, the supply pumps
                      will automatically stop, the control system will energize the day tank leak
                      alarm light, sound the alarm bell and close the day tank supply solenoid
                      valve.
                   2) The day tank vent leak detector is hard-wired to a DPDT relay. The relay
                      is wired in series with the supply pump motor starter holding coils so that
                      if the vent leak detector trips, the supply pumps will automatically stop.
               F. Day Tank Rupture Basin Alarm
                   1) A day tank rupture basin leak detection will energize the day tank leak
                      light, sound the alarm bell and de-energized the day tank supply solenoid
                      valve. Upon correction or alarm condition, the leak alarm circuit will
                      automatically be reset. An alarm event is logged in the alarm log.

Waste Water Treatment Facility

               G. Pump Failure
                   1) To prove pump operation, the supply pump motor starter auxiliary contact
                      must close and there must be oil flow as detected by the oil flow switch. In
                      the event either condition does not occur, the MCP will automatically
                      switch to the lag pump and start the lag pump and sound the alarm.
               H. Pump Control Monitoring
                   1) The MCP monitors the HOA switch positions. If the pumps are placed in
                      the hand or off position, the MCP will alarm to the BMS that the pumps
                      have been manually commanded on or off.
               I. Transition Sump and Tank Top Sump Alarm
                   1) A transition sump leak detection will cause the MCP to energize the
                      transition sump leak light, sound the alarm bell and de-energize the supply
                      pump. When the alarm condition is corrected, the leak alarm circuit will
                      automatically be reset. The alarm event is logged in the alarm log. The
                      location of the leak will be displayed on the touch screen system graphic.
               J. Main Tank Level Monitoring System
                   1) The MCP monitors the analog level in gallons of the bulk storage tank.
                      The MCP displays this information on the touch screen and transmits this
                      information to the BMS via modbus or BACnet. The MCP will
                      automatically alarm for fuel re-order level (adjustable).
               K. Remote Overfill Alarm
                   1) If the tank reaches the 90% level during a fill operation, the overfill alarm
                      horn and strobe will be energized. The fill operator can access the silence
                      switch to stop the horn, but the overfill alarm light will remain energized.
                      When the bulk storage tank level rises to 95%, the mechanical overflow
                      prevention valve will close, preventing overfill.

PART 3 EXECUTION

3.1.   Inspection
       3.1.1. Inspection:
               A. Prior to all work of this Section, carefully inspect the installed work of all
                  other trades and verify that all such work is complete to the point where this
                  installation may properly commence.
               B. Verify that all pipe may be installed in accordance with all pertinent codes and
                  regulations, the original design, and the referenced standards.
       3.1.2. Discrepancies:
               A. In the event of discrepancy, immediately notify the COTR.
               B. Do not proceed with installation in areas of discrepancy until all such
                  discrepancies have been fully resolved.
3.2.   Installation
       3.2.1. General:
               A. Install all pipes in strict accordance with plans, profiles, typical sections and
                  with manufacturer's written recommendations as approved by the COTR and
                  according to the California Department of Health Services’(DHS)
                  requirements. Appendix I contains DHS standards applicable to this project.
       3.2.2. Pressure pipe:
               A. Pressure pipe shall be laid in accordance with plans and profiles and typical
                  sections. Before new pipe is placed the subgrade material shall be graded so
                  that pipe will rest firmly on undisturbed granular material for its full length.
               B. In general, this should be accomplished by the inclusion of imported bedding
                  material as shown on the plans. All adjustments to line and grade shall be
                  made by scraping away or filling in the bedding to the body of the pipe and in
                  no case by wedging a blocking. Pipe shall be laid on an unyielding foundation
                  to proper line and grade with uniform bearing under the full length of the pipe
                  with slight hand excavation for the coupling to allow for its thickness.
               C. Where soft, wet or spongy conditions are encountered in the trench at pipe
                  subgrade, this foundation situation shall be corrected by the use of imported
                  stabilization material as specified in Section 02221.
               D. Carefully inspect all pipe, valves, and other appurtenances for cracks or other
                  prior to installation. Replace all damaged piping or appurtenances. Under no
                  circumstances shall damaged material be installed. Carefully lower pipe into
                  trench to prevent damage. Under no circumstances shall pipe be dropped into
                  trenches.
               E. All pipe, especially the ends, shall be carefully cleaned before the pipe is
                  joined. Whenever work ceases for any reason, the end of the pipe shall be
                  closed with a water-tight fitting, plug or cover. The interior of the pipe shall

Waste Water Treatment Facility

                   be kept free from dirt, foreign material or debris as the work progresses and
                   the pipe shall be cleaned after completion.
               F. Support pipe as required during installation to prevent distortion of pipe
                  before backfilling or installing permanent supports.
               G. Pressure line shall be laid to the line and grade shown on the plans. In
                  instances where grade shows constant uphill grade to structures or air relief
                  valve, the Contractor shall take all precautions necessary to secure continual
                  smooth alignment to such appurtenances.
               H. Fabricate and install pipe supports for aboveground piping as required and at
                  sufficient intervals to keep pipe in alignment and support the weight of the
                  pipe and its contents. Install hangers or supports at ends of runs or branches
                  and at each change of direction or alignment. Install pipe so as not to induce
                  strain or equipment.
               I. Repair any damaged coating per manufacturers written instructions. Touch up
                  any damaged paint as per specification Section 09900.
3.3.   Protection, barricades, etc.
       3.3.1. Pipe strung out along the trench or stored where it can be damaged or where
              injury may result to the public shall have special precautions taken to prevent
              damage from occurring. Pipe shall not be spread along trenches for extended
              periods prior to its actual use. Pipe shall be stored in a safe location out of the
              traveled way and properly barricaded with suitable lights provided to prevent
              vehicular damage.
       3.3.2. Where pipe is stored off of a right-of-way, the Contractor shall be required to
              obtain a letter of consent from the affected property owner prior to storage in such
              locations. Such letters shall be obtained and given to the COTR prior to use of
              private property.
       3.3.3. See Plans for typical barricades and safety precautions. In general, the "Manual of
              Warning Sings, Lights, and Devices for Use in Performance of Work upon
              Highways" issued by Caltrans shall be used as a minimum for the safety
              requirements to be used on this work.
3.4.   Laying, Bedding
       3.4.1. All buried pipe shall be laid on a prepared bed as hereinbefore specified. After
              laying, additional bedding material shall be added to a depth of 3 inches or about
              the mid-point of the pipe depending upon diameter, after which it shall be tamped
              with a suitable tool to secure uniform full length bedding up to the mid-point of
              the pipe. Additional bedding material shall then be placed to the depth shown in
              the standard details of the Plans and compacted by mechanical methods to a
              relative compaction of 90 percent.
       3.4.2. Take necessary precautions to prevent uplift and floating of the pipe prior to
              backfilling.

              pump station.
       3.4.4. Water in trenches shall be removed by pumping.
3.5.   Cutting Pipe
       3.5.1. General:
               A. Cut pipe for inserting valves, fittings, closure pieces, and as otherwise
                  required, in a neat and workmanlike manner without damaging the pipe or
                  lining and so as to leave a smooth end at right angles to the axis of the pipe.
       3.5.2. Cast iron and ductile iron pipe:
               A. Cut pipe with milling-type cutter, rolling pipe cutter, abrasive saw cutter, or
                  with sledge and cold cutter. Do not flame cut.
       3.5.3. Dressing cut ends:
               A. Dress cut ends of pipe in accordance with the type of joint to be made.
               B. Dress cut ends of mechanical joint pipe to remove sharp edges or projections
                  which may damage the rubber gasket.
               C. Dress cut ends of push-on joint pipe by beveling, as recommended by the
                  coupling or adapter manufacturer.
3.6.   Installation of Pipe through Slabs and Existing Walls
       3.6.1. Concrete walls and slabs:
               A. Install wall sleeves before concrete placement. Set sleeves in position
                  formwork and provide reinforcement around sleeves. Extend sleeves through
                  slabs one inch above finished floor. Clearance between pipe and sleeve shall
                  conform to requirements in NFPA Pamphlets No. 13 and 24. For pipes 3.5
                  inch and smaller, pipe sleeve shall be a nominal diameter 2 inch larger in size
                  than the nominal diameter of the pipe. For pipes 4 inch and larger, pipe sleeve
                  shall be a nominal diameter 4 inches larger in size than the nominal diameter
                  of the pipe. Where piping penetrates existing wall, install sleeve and grout in
                  place with non-shrink grout. Install mastic or other approved flexible sealant
                  between pipe and sleeve wall throughout full depth of sleeve.
3.7.   Appurtenances
       3.7.1. General:
               A. See plans for location of valves and appurtenances to be installed as a portion
                  of the pressure line. The Contractor should note that generally, valves that are
                  clustered are flanged by hub with the entire cluster properly bolted together.
                  Valves and other appurtenances having hub ends shall be connected to the
                  pipe by means of rubber rings of the same type used to join the pipe.
       3.7.2. Thrust blocks:
               A. Thrust blocking shall be provided at all valves, bends, tees, crosses and
                  reducers. Thrust block shall be constructed in accordance with standards
PROJECT NO. 3597135                    15200 –11 Piping System
United States Coast Guard TRACEN Petaluma
Waste Water Treatment Facility

                   shown on the Plans and as specified in Section 03300. Ground against which
                   the concrete is being placed shall be moistened (if needed) prior to placing so
                   that it will not absorb excessive moisture from the fresh concrete. Forms
                   where required shall be smooth and tight of sufficient strength to maintain
                   their shape during placing of the concrete. Placing methods shall be such that
                   the concrete will be placed in its final position without segregation. All
                   concrete shall be rodded in place to insure smooth surfaces along form lines.
                   Blocking shall be placed against undisturbed earth in such manner that pipe
                   and fitting joints or valves will be accessible for repair. The relative area of
                   thrust block required for various pressures and degrees of earth restraint are
                   noted on the plans. Where poor soil and higher pressures are encountered,
                   greater area of thrust block may be required.
       3.7.3. Joining mechanical joint pipe:
               A. Mechanical joint pipe varies slightly with different manufacturers. Install the
                  particular pipe furnished in accordance with the manufacturer's written
                  recommendations as approved by the COTR.
       3.7.4. Joining push-on joint pipe:
               A. Join pipe with push-on type joints in accordance with the manufacturer's
                  recommendations as approved by the COTR. Provide all special tools and
                  devices, such as special jacks, chokers, and similar items required for the
                  installation. Lubricant for the pipe gaskets shall be furnished by the pipe
                  manufacturer, and no substitutes will be permitted.
       3.7.5. Joining flanged joint pipe
               A. Prior to connecting flanged pipe, the faces of the flanges shall be thoroughly
                  cleaned of all oil, grease, and foreign material. The rubber gaskets shall be
                  checked for proper fit and thoroughly cleaned. Care shall be taken to assure
                  proper seating of the flanged gasket. Bolts shall be tightened in rotation so that
                  the pressure on the gasket is uniform. Torque-limiting wrenches shall be used
                  to insure uniform bearing insofar as possible. If joints leak when the
                  hydrostatic test is applied, the gaskets shall be removed and reset and bolts
                  retightened. Leave flange bolts with ends projecting 1/3 to 3/8 inch beyond
                  the face of the nut after tightening.
3.8.   Cleaning
       3.8.1. Care shall be taken to keep the pipe clean at all times during the installation. Prior
              to final connection to equipment or fire system risers the pipe shall be flushed so
              that velocities of 10 feet per second are obtained. Maintain for a sufficient time to
              clean the entire length of pipe. Contractor shall be responsible for disposal of
              water from flushing and testing procedures. Care shall be exercised to ensure that
              no equipment, structures, or landscaping shall be damaged by flush water.
              Contractor is responsible for repairing all damage at no cost to the Government.
3.9.   Tests
       3.9.1. General:

PROJECT NO. 3597135                    15200 –12 Piping System
United States Coast Guard TRACEN Petaluma
Waste Water Treatment Facility

               A. Upon completion of this portion of the work, and prior to its acceptance by the
                  Government, complete all tests.
       3.9.2. Hydrostatic testing:
               A. General:
                   1) Conduct pressure and leakage tests on all pipelines. Furnish all necessary
                      equipment and material and make all taps in the pipe as required. Notify
                      the COTR prior to beginning the tests. The Contractor shall hire a Fire
                      Protection Engineer to monitor all fire system piping and to certify it is in
                      compliance with codes. All pipe testing is to be hydrostatic.
                   2) Furnish the following equipment and materials for the tests in sufficient
                      quantity to complete all tests: approved graduated containers, approved
                      pressure gauges, hydraulic force pump approved by the COTR and
                      suitable hose and suction pipe as required.
                   3) Gauges for testing shall be calibrated with a standardized test gauge at the
                      start of each testing day. The calibration shall be witnessed by the COTR.
                   4) Conduct hydrostatic testing of all fire service piping systems in
                      compliance with NFPA, Pamphlet No. 24. Testing shall also conform to
                      the requirements of AWWA C600.
                   5) Conduct the tests on buried pipe after the trench has been completely
                      backfilled. The Contractor may, if field conditions permit, partially
                      backfill the trench and leave the joints open for inspection and conduct an
                      initial test. The acceptance test shall not, however, be conducted until all
                      backfilling has been completed. Conduct the tests on exposed piping after
                      the piping has been completely installed, including all supports and
                      hangers.
               B. Pressure pipe procedure:
                   1) After the pipe has been laid and backfilled and final compaction has been
                      obtained, the Contractor shall test pressure pipe between each valve
                      section or pipe run. The pipe shall be slowly filled with water so that air is
                      removed. Before applying the specified test pressure, air shall be expelled
                      completely from the pipes, valves and other appurtenances. If permanent
                      air vents are not located at all high points, the Contractor shall install
                      corporation cocks at such points so that the air can be expelled as the line
                      is filled with water. At the end of the pressure test, the corporation cocks
                      shall be removed and plugged or left in place at the discretion of the
                      Government. The pipe shall be tested hydrostatically to a pressure of 200
                      psi for a minimum of two hours. Reaction blocking pipe restraints and the
                      like shall be installed prior to test. Protect all equipment, which may be
                      damaged by the test pressure by isolating. Take all necessary precautions
                      to prevent any joints from drawing while the pipelines are being tested.
                      Repair any damages to the pipes or appurtenances or to any other
                      structures resulting from or caused by these tests. The costs for these
                      repairs shall be at no cost to the Government.

Waste Water Treatment Facility

                   2) All exposed pipe, fittings, valves and joints shall be examined during the
                      test for seepage or other defects. Defects noted by this test shall be
                      removed and replaced by the Contractor with sound material. Afterwards,
                      the test shall be repeated to the satisfaction of the COTR.
                   3) In addition, a leakage test shall be conducted by the Contractor after the
                      pressure test has been satisfactorily completed. The duration of each
                      leakage test shall be two hours and during the test the main shall be
                      subjected to a pressure of l00 psi unless elsewhere specified. No visible
                      leakage shall be allowed on above ground piping. Leakage for fire system
                      piping shall not exceed 2 quarts per hour per 100 joints irrespective of the
                      pipe diameter. Leakage shall not exceed that as shown in Table 3 of
                      AWWA Standard C600 or not in excess of l0 gallons per day per inch
                      diameter per mile.
                   4) If any test discloses leakage greater than specified, the Contractor shall at
                      his own expense locate and repair the defective joints until the leakage is
                      within the specified allowance. All control valves shall be full opened and
                      closed under system pressure to ensure proper operation.
               C. Requirements for exposed pipelines:
                   1) All exposed pipelines piping shall have no visible leakage during the
                      specified test period. Any exposed pipeline with leakage shall be repaired
                      or replaced.
3.10.   Repairs
        3.10.1. Only new pipe free from defects shall be installed. Portions of broken pipe or
                short lengths may be used providing they are properly cut back and used as stubs,
                or short lengths required at structures for flexible joints.

3.2.   Preparation
       3.2.1. Furnish instruments required for testing, adjusting, and balancing operations.
       3.2.2. Make instruments available to Architect/Engineer to facilitate spot checks during
              testing.
3.3.   Installation Tolerances
       3.3.1. Air Handling Systems: Adjust to within plus or minus 10 percent of design.
       3.3.2. Air Outlets and Inlets: Adjust total to within plus 10 percent and minus 5 percent
              of design to space. Adjust outlets and inlets in space to within plus or minus 10
              percent of design.
3.4.   Adjusting
       3.4.1. Verify recorded data represents actual measured or observed conditions.
       3.4.2. Permanently mark settings of dampers and other adjustment devices allowing
              settings to be restored. Set and lock memory stops.
       3.4.3. After adjustment, take measurements to verify balance has not been disrupted. If
              disrupted, verify correcting adjustments have been made.
       3.4.4. Report defects and deficiencies noted during performance of services, preventing
              system balance.
       3.4.5. Leave systems in proper working order, replacing belt guards, closing access
              doors, closing doors to electrical switch boxes, and restoring thermostats to
              specified settings.
3.5.   Air System Procedure
       3.5.1. Adjust air handling and distribution systems to obtain required or design supply,
              return, outside air, and exhaust air quantities.
       3.5.2. Make air quantity measurements in main ducts by Pitot tube traverse of entire
              cross sectional area of duct.
       3.5.3. Measure air quantities at air inlets and outlets.
       3.5.4. Use volume control devices to regulate air quantities only to extent adjustments
              do not create objectionable air motion or sound levels. Effect volume control by
              using volume dampers located in ducts.
       3.5.5. Vary total system air quantities by adjustment of fan speeds. Provide sheave drive
              changes to vary fan speed. Vary branch air quantities by damper regulation.
       3.5.6. Provide system schematic with required and actual air quantities recorded at each
              outlet or inlet.
       3.5.7. Measure static air pressure conditions on air supply units, including filter and coil
              pressure drops, and total pressure across fan. Make allowances for 50 percent
              loading of filters.
