ESTIMATED LOCATIONS ARE LOCATED ON THE PLANS. 11. LOCATIONS OF QUICK COUPLER VALVES SHALL BE TO THE FRONT LEFT AND BACK REAR OF THE GREENS AND FINALIZED IN FIELD DURING CONSTRUCTION BY THE OWNER'S REPRESENTATIVE. ALL QUICK COUPLE VALVES LOCATED ON GREENS SHALL BE INSTALLED WITHIN 1m (3') OF A SPRINKLER UNLESS OTHERWISE DIRECTED BY THE OWNER'S REPRESENTATIVE. SPARE 24V WIRE (SATELLITE SYSTEM) OR DECODER CABLE SHALL BE RUN TO EACH QUICK COUPLER.
12. ALL FITTING CONNECTIONS FOR GREEN AND TEE SPRINKLERS SHALL BE DIRECTED AWAY FROM PUTTING GREEN OR TEE SURFACES.
13. PIPING TO TEE SPRINKLERS WITHIN THE TEE SURFACES SHALL BE KEPT TO A MINIMUM.
14. IRRIGATION CONTRACTOR SHALL THOROUGHLY COMPACT ALL MAINLINE TRENCHES IN LIFTS NOT TO EXCEED 30 cm (12") WITH A VERMEER TRENCH COMPACTION MACHINE OR EQUIVALENT. FINAL ACCEPTANCE OF TRENCH BACKFILL SHALL REST WITH OWNER'S REPRESENTATIVE.
15. ROUTES OF MAIN LINE PIPES MAY REQUIRE ADDITIONAL FITTINGS TO AVOID EXISTING TREES OR VEGETATION, LAKES AND/OR STREAMS, FEATURES CONSTRUCTION OR UTILITIES WHICH MAY NOT BE CLEARLY IDENTIFIED UNTIL CONSTRUCTION HAS BEGUN. CONTRACTOR SHALL PROVIDE ALL FITTINGS, CONNECTORS, JOINT RESTRAINTS, ETC. AS MAY BE REQUIRED TO SO AS TO NOT EXCEED RECOMMENDED PIPE CURVATURE.
16. MAXIMUM DEFLECTION OF HDPE PIPE SECTIONS SHALL BE KEPT TO TWENTY-FIVE TO ONE RATIO OR LESS, OR AS DESIGNATED BY PIPE MANUFACTURER, WHICHEVER IS LESS.
17. ALL TRENCH LINES SHALL BE KEPT OUT OF DRIP LINES OF TREES EXCEPT AS DIRECTED AND APPROVED BY THE OWNER'S REPRESENTATIVE.
18. ALL TRENCHES LOCATED IN ROCK OR OTHERWISE UNSUITABLE SOILS SHALL BE OVER-EXCAVATED TO A MINIMUM OF 75 mm (3") AND 75mm (3") OF SAND SHALL BE PLACED BELOW ALL PIPING AND WIRING, AND A MINIMUM OF 150mm (6") PLACED ABOVE ALL PIPING AND WIRING. THE REMAINING MATERIAL FOR TRENCH BACKFILL SHALL BE CLEAN AND FREE OF ORGANIC DEBRIS AND ROCKS AND APPROVED BY EITHER THE CONSULTANT OR OWNER'S REPRESENTATIVE BEFORE PLACEMENT IN TRENCH.
19. CONTRACTOR SHALL PROVIDE PERMANENT MARKERS FOR ENDS OF ALL PIPE SLEEVES AND ENDS OF ALL PIPES BURIED ACROSS STREAMS, DRAINAGE CHANNELS AND/OR EASEMENTS.
20. CONTRACTOR SHALL COORDINATE INSTALLATION OF ALL PIPING TO BE SUPPORTED OR SUSPENDED ON BRIDGES WITH OWNER'S REPRESENTATIVE DURING CONSTRUCTION.
21. ROUTING OF MAIN LINE PIPING AROUND CLUBHOUSE AREA, ROADWAYS AND/OR EXISTING STRUCTURES AND UTILITIES SHALL BE COORDINATED WITH OWNER'S REPRESENTATIVE(S) PRIOR TO EXCAVATION OF TRENCHES.
22. ALL QUICK COUPLER VALVES SHALL BE INSTALLED OUTSIDE OF GREEN SURFACES AND INSTALLED AS CALLED FOR IN THE DETAILS.
23. ALL MAINLINE STUB-OUTS ARE TO BE CAPPED AT THE TEE AND THRUST BLOCKED. THE LOCATION SHALL BE MARKED BY A 10" ROUND VALVE BOX.
24. CONTRACTOR IS RESPONSIBLE FOR ALL EXISTING MAINLINE TIE-IN'S NOTED ON PLAN AND ANY OTHERS REQUIRED TO KEEP THE EXISTING SYSTEM OPERATIONAL WHILE THE NEW SYSTEM IS INSTALLED.
25. CONTRACTOR WILL BE RESPONSIBLE TO REPAIR ALL EXISTING PIPE, POWER WIRE AND 24V STATION WIRE TO MAINTAIN EXISTING IRRIGATION SYSTEM
