HomeMy WebLinkAboutFORT COLLINS RESCUE MISSION - FDP230022 - SUBMITTAL DOCUMENTS - ROUND 3 - Irrigation PlansINSTALLATION GENERAL NOTES
1.DESIGN ASSUMES A MINIMUM DYNAMIC PRESSURE AVAILABLE FOR THE IRRIGATION
SYSTEM (NOT OBTAINED) OF 80 PSI, AT A MAXIMUM PEAK FLOW OF 10 GPM AT THE
EXISTING 3/4-INCH POINT-OF-CONNECTION (POC). VERIFY PRESSURE AND FLOW ON SITE
PRIOR TO CONSTRUCTION. CONTACT GENERAL CONTRACTOR OR OWNER'S
REPRESENTATIVE IMMEDIATELY IF FLOW OR PRESSURE ARE LOWER THAN LISTED ABOVE.
1.1.IRRIGATION TAP, METER, SERVICE LINES, AND BACKFLOW SHALL ALL BE THE SAME
SIZE, AS STATED ABOVE.
1.2.EXISTING CONTROLLER INSTALLED WITHIN FIRST PHASE IS A HUNTER 2-WIRE
CONTROLLER. UTILIZE DECODERS PER DETAILS AND SPECIFICATIONS.
2.ALL MAINLINES SHALL BE INSTALLED AT LEAST 5' FROM CENTER OF TREES, WHERE
POSSIBLE. DESIGN IS SHOWN FOR CLARITY, THUS MAINLINE ROUTING IN FIELD MAY LOOK
SLIGHTLY DIFFERENT THAN DEPICTED IN DRAWINGS.
3.CONTRACTOR SHALL CREATE A LAMINATED CONTROLLER CHART ADHERED TO THE
INSIDE OF THE CONTROLLER COVER OR A LAMINATED COLORED CONTROLLER MAP.
4.CONTRACTOR SHALL BECOME FAMILIAR WITH THE SPECIFICATIONS AND
INSTALLATION DETAILS FOR THIS AND RELATED WORK PRIOR TO CONSTRUCTION. FOR
CLARIFICATION, CONTACT IRRIGATION DESIGNER PRIOR TO CONSTRUCTION.
4.1.UPON FINAL ACCEPTANCE, CONTRACTOR SHALL TURN OVER REQUIRED
ADJUSTMENT KEYS INCLUDING BUT NOT LIMITED TO CONTROLLER ENCLOSURE AND
BACKFLOW ENCLOSURE KEY, LOCKING VALVE BOX KEYS, QUICK COUPLER KEYS, GATE
VALVE KEY, SPRINKLER HEAD AND NOZZLE ADJUSTMENT KEYS.
4.2. UPON FINAL ACCEPTANCE, CONTRACTOR SHALL TURN OVER SPARE PARTS
PERTAINING TO INSTALLED SYSTEM: BACKFLOW WINTERIZATION INSERT, TWO OF
EVERY HEAD AND NOZZLE (ROTOR NOZZLE TREE INCLUDED), ONE RCV DIAPHRAGM,
ETC.
5.COORDINATE UTILITY LOCATES OF UNDERGROUND UTILITIES PRIOR TO
CONSTRUCTION ("811-CALL BEFORE YOU DIG") .
6.IF DISCREPANCIES ARE NOTED IN THE FIELD BETWEEN SITE CONDITIONS AND
PROVIDED DESIGNS, CONTRACTOR SHALL NOTIFY OWNER'S REPRESENTATIVE OR
GENERAL CONTRACTOR IMMEDIATELY. DO NOT PROCEED WITH THE INSTALLATION OF
THE IRRIGATION SYSTEM IF SUCH DISCREPANCIES IN THE FIELD AFFECT THE PROVIDED
DESIGN, DETAILS, OR SPECIFICATIONS.
7.ALL IRRIGATION COMPONENTS (MAINLINE, WIRES, LATERAL LINES, ETC.) SHALL BE
INSTALLED IN LANDSCAPED AREAS WHENEVER POSSIBLE, EVEN THOUGH SAID IRRIGATION
COMPONENTS MAY BE SHOWN OUTSIDE PLANTING AREAS FOR CLARITY.
8. AVOID CONFLICTS BETWEEN THE IRRIGATION SYSTEM, PLANTING MATERIALS, AND
ARCHITECTURAL FEATURES WHENEVER POSSIBLE. COORDINATE POTENTIAL RELOCATION
OF BOULDERS AND TREES IN TURF AREAS WITH LANDSCAPE ARCHITECT PRIOR TO
SPRINKLER LAYOUT. IF LANDSCAPE MATERIAL CANNOT BE RELOCATED,ADDITIONAL
SPRINKLERS MAY BE REQUIRED.
8.1.WHERE POSSIBLE, MAINTAIN 3'-5' DISTANCE FROM CENTER OF TREE TO MAINLINE
AND WIRES. VALVE BOXES SHALL BE AT LEAST 3' FROM TREE CENTER. MAINLINE
ROUTING AND VALVE LOCATIONS ARE SHOWN FOR CLARITY AND MAY BE SHOWN
WITHIN THE 3'-5' RANGE NOTED ABOVE.
9. CROSS FITTINGS ARE NOT ALLOWED, ONLY STANDARD TEES AND ELBOWS.
10.CONTRACTOR SHALL INSTALL NOZZLES PER PLAN, UNLESS IRRIGATED AREA
CHANGED IN SIZE OR PLANT MATERIAL TYPE CHANGES. IF NOZZLE CHANGES ARE
REQUIRED AND ARE SIGNIFICANT IN SIZE, CONTRACTOR SHALL CONTACT IRRIGATION
DESIGNER FOR APPROVAL.
11.CONTRACTOR SHALL FIELD LOCATE ANY EXISTING SLEEVES ON SITE PRIOR TO
CONSTRUCTION WITH THE AID OF THE GENERAL CONTRACTOR. MISSING SLEEVES SHALL
BE REPORTED IMMEDIATELY. NEW SLEEVES SHOWN ON PLANS ARE REQUIRED FOR BOTH
PIPING AND ELECTRICAL WIRING AT EACH HARDSCAPE CROSSING. COORDINATE
INSTALLATION OF SLEEVING WITH OTHER TRADES. ANY PIPE OR WIRE WHICH PASSES
BENEATH EXISTING HARDSCAPE WHERE SLEEVING WAS NOT INSTALLED WILL REQUIRE
HORIZONTAL BORING BY THE IRRIGATION CONTRACTOR.
12.INSTALL ALL ELECTRICAL POWER TO THE IRRIGATION CONTROL SYSTEM IN
ACCORDANCE WITH THE NATIONAL ELECTRIC CODE AND ALL APPLICABLE LOCAL
ELECTRIC UTILITY CODES.
13.THE FOLLOWING SHOULD BE NOTED REGARDING PIPE SIZING: IF A SECTION OF
UNSIZED PIPE IS LOCATED BETWEEN THE IDENTICALLY SIZED SECTIONS, THE UNSIZED
PIPE IS THE SAME NOMINAL SIZE AS THE TWO SIZED SECTIONS. THE UNSIZED PIPE
SHOULD NOT BE CONFUSED WITH THE DEFAULT PIPE SIZE NOTED IN THE LEGEND.
13.1.MAINLINE PIPE SIZES MAY VARY THROUGHOUT PROJECT. EACH MAINLINE LEG
IS SIZED TO ACCOMMODATE LARGEST VALVE ON THAT LEG. STATED SIZE IN LEGEND
MAY NOT BE THE LARGEST SIZE ON PLANS.
14.TWO-WIRE CONTROL CABLE DOES NOT REQUIRE ADDITIONAL SPARE WIRES TO BE
ROUTED WITH MAINLINE.
14.1.TWO-WIRE CONTROL SURGE ARRESTORS SHALL BE INSTALLED PER
MANUFACTURER'S RECOMMENDATIONS. ARRESTORS ARE NOT DEPICTED ON PLANS
15.TREES IN TURF ARE NOT IRRIGATED BY DRIP SYSTEM. DRIP LATERAL ROUTED NEAR
TREES IN TURF ARE NOT TO RECEIVE DRIP IRRIGATION. TREES IN NATIVE SEEDED AREAS
ARE IRRIGATED ON DRIP SYSTEM.
16.VALVES FOR NATIVE SEEDED AREAS SHALL BE ON A SEPARATE PROGRAM.
17.NATIVE SEEDED AREAS ARE TO BE IRRIGATED WITH A BELOW GRADE SYSTEM BUT
UTILIZED FOR ESTABLISHMENT OF SEED. SYSTEM IS NOT INTENDED TO OPERATE BEYOND
ESTABLISHMENT.
18.NO IRRIGATION EQUIPMENT, INCLUDING BUT NOT LIMITED TO, MAINLINE, VALVES,
AND SPRINKLERS, SHALL BE INSTALLED WITHIN 3' OF NEW BUILDING FOUNDATION.

D.Flush Cap Assembly: Install at the end of each drip irrigation lateral pipe as shown on the installation
details.
3.9 INSTALLATION OF CONTROL SYSTEM COMPONENTS
A.Irrigation Controller Unit:
1.Install one valve output surge protection arrestor on each control wire and one for the common
wire.
2.Attach wire markers to the ends of control wires inside the controller unit housing. Label wires with
the identification number (see drawings) of the remote control valve to which the control wire is
connected.
3.Install a 120-volt, 15 amp switched and grounded 3-prong receptacle with GFIC inside the
controller unit housing.
4.Connect control wires to the corresponding controller terminal.
B.Control Wire:
1.Bundle control wires where two or more are in the same trench. Bundle with pipe wrapping tape
spaced at 10-foot intervals.
2.Provide a 24-inch excess length of wire in an 8-inch diameter loop at each 90 degree change of
direction, at both ends of sleeves, and at 100-foot intervals along continuous runs of wiring. Make
wiring loop by turning control wire 5 turns around 1-inch pipe. Coil 24-inch length of wire within
each remote control valve box.
3.Install common ground wire and one control wire for each remote control valve. Multiple valves on
a single control wire are not permitted.
4.If a control wire must be spliced, make splice with wire connectors and waterproof sealant,
installed per the manufacturer's instructions. Locate splice in a valve box which contains an
irrigation valve assembly, or in a separate 6-inch round valve box.
Use same procedure for connection to valves as for in-line splices.
5.Unless noted on plans, install wire parallel with and under PVC mainline pipe. If wire is installed
adjacent to section of metal pipe, separate wire from pipe minimum of 6-inches and install wire in
PVC conduit.
6.Encase wire not installed with PVC mainline pipe in electrical conduit. Or protect wire not installed
with PVC mainline pipe with a continuous run of warning tape placed in the backfill six inches
above the wiring.
7.Install surge protection along wires per Manufacturer's recommendations.
3.11 INSTALLATION OF OTHER COMPONENTS
A.Tools and Spare Parts:
1.Prior to the Pre-Maintenance Review, supply to the Owner operating keys, servicing tools, test
equipment, and any other items indicated on the drawings.
2.Prior to Final Review, supply to the Owner the spare parts indicated in the General Notes on the
drawings.
B.Other Materials: Install other materials or equipment shown on the drawings or installation details to
be part of the irrigation system, even though such items may not have been referenced in these
specifications.
3.12 PROJECT RECORD (AS-BUILT) DRAWINGS
A.Maintain on-site and separate from documents used for construction, one complete set of contract
documents as Project Documents. Keep documents current. Do not permanently cover work until
as-built information is recorded.
B.Record pipe and wiring network alterations. Record work which is installed differently than shown on
the construction drawings. Record accurate reference dimensions, measured from at least two
permanent reference points, of each irrigation system valve, each backflow prevention device, each
controller or control unit, each sleeve end, each stub-out for future pipe or wiring connections, and
other irrigation components enclosed within a valve box.
C.Prior to Final Review, purchase from the Owners' Representative a reproducible mylar copy of the
drawings. Using technical drafting pen, duplicate information contained on the project drawings
maintained on site. Label each sheet "Record Drawing". Completion of the Record Drawings will be
a prerequisite for the Final Review.
3.13 MAINTENANCE
A.Upon completion of Final Review, maintain irrigation system for a duration of 30 calendar days. Make
periodic examinations and adjustments to irrigation system components so as to achieve the most
desirable application of water.
B.Following completion of the Contractor's maintenance period, the Owner will be responsible for
maintaining the system in working order during the remainder of the guarantee/warranty period, for
performing necessary minor maintenance, for trimming around sprinklers, for protecting against
vandalism, and for preventing damage during the landscape maintenance operation.
3.14 CLEAN-UP
A.Upon completion of work, remove from the site all machinery, tools, excess materials, and rubbish.
