THE SYSTEM DESIGN IS BASED ON XX PSI AND XX GPM AVAILABLE AT THE POINT OF CONNECTION. THE CONTRACTOR IS RESPONSIBLE FOR VERIFYING THESE REPORTED READINGS PRIOR TO CONSTRUCTION. IF A DISCREPANCY EXISTS BETWEEN THE REPORTED AND THE FOUND READINGS THAT WILL ADVERSELY AFFECT THE OPERATION OF THE SYSTEM, CEASE CONSTRUCTION ACTIVITY AND NOTIFY THE CLIENT REPRESENTATIVE AT ONCE BY TELEPHONE AND IN WRITING. THE CONTRACTOR SHALL OBTAIN AUTHORIZATION FROM THE CLIENT REPRESENTATIVE BEFORE PROCEEDING WITH IRRIGATION SYSTEM INSTALLATION. IN THE EVENT A PRESSURE DISCREPANCY IS NOT REPORTED IN WRITING PRIOR TO THE START OF CONSTRUCTION, THE CONTRACTOR SHALL ASSUME FULL RESPONSIBILITY FOR ANY NECESSARY REVISIONS. CODES: INSTALLATION SHALL OCCUR IN ACCORDANCE WITH ALL LOCAL CODES AND MANUFACTURER'S SPECIFICATIONS. NOTIFY THE CLIENT REPRESENTATIVE BY TELEPHONE AND IN WRITING OF ANY CONFLICTS PRIOR TO CONSTRUCTION. SYSTEM INSTALLATION: INSTALL IRRIGATION SYSTEM AS SHOWN ON PLAN AND CONSTRUCTION DETAILS. DO NOT WILLFULLY INSTALL THE IRRIGATION SYSTEM AS DIAGRAMMATICALLY SHOWN ON THE DRAWINGS WHEN IT IS OBVIOUS IN THE FIELD THAT OBSTRUCTIONS, GRADE DIFFERENCES, OR DIFFERENCES IN SITE DIMENSIONS EXIST THAT MIGHT NOT HAVE BEEN FORESEEN AND CONSIDERED IN THE IRRIGATION SYSTEM DESIGN. INSTALL ALL PIPING AND VALVES IN COMMON TRENCHES WHERE FEASIBLE AND INSIDE PLANTING AREAS WHENEVER POSSIBLE. ALL VALVES SHALL BE LOCATED IN GROUNDCOVER/SHRUB AREAS AND INSTALLED A MAXIMUM OF 12" AWAY FROM BACK OF WALKS, WALLS, OR MOWBANDS. MAINLINE SHALL BE ROUTED AT THE BACK OF WALK AS MUCH AS POSSIBLE. IF DIFFERENCES OR OBSTRUCTIONS EXIST IN THE FIELD THAT WILL NOT ALLOW FOR THE INSTALLATION OF THE IRRIGATION SYSTEM AS DIAGRAMMATICALLY SHOWN, THE CLIENT REPRESENTATIVE SHOULD BE INFORMED BY TELEPHONE AND IN WRITING BEFORE PROCEEDING. IN THE EVENT THAT THIS NOTIFICATION IS NOT PERFORMED, THE CONTRACTOR SHALL ASSUME FULL RESPONSIBILITY FOR ANY REVISIONS AND REPAIR WORK NECESSARY. TESTING: PRIOR TO BACKFILLING TRENCHES THE CONTRACTOR SHALL CHARGE THE MAINLINE AND TEST SYSTEM FOR LEAKS AND REPAIR THE MAINLINE AS NECESSARY. THE CONTRACTOR SHALL ALSO TEST THE CONTROLLER AND WIRING SYSTEM TO VALVES ENSURING OPERABILITY PRIOR TO BACKFILLING TRENCHES. BACKFLOW PREVENTER: LOCATE PER PLAN, AND OBTAIN APPROVAL FROM THE CLIENT REPRESENTATIVE PRIOR TO INSTALLATION. CONTROLLER: THE FINAL LOCATION OF THE AUTOMATIC CONTROLLER SHALL BE APPROVED BY THE CLIENT REPRESENTATIVE PRIOR TO INSTALLATION. THE CONTRACTOR IS RESPONSIBLE FOR PROVIDING CONDUIT AND WIRE FROM SECONDARY SERVICE POINT TO CONTROLLER A PER PLAN. SEE PLANS FOR ADDITIONAL INFORMATION. SLEEVING: CONTRACTOR SHALL ADEQUATELY SIZE ALL SLEEVES SHOWN ON PLAN. SLEEVES SHALL BE INSTALLED AT THE NECESSARY DEPTHS PRIOR TO PAVEMENT CONSTRUCTION AS SHOWN ON PLANS. SLEEVING SHALL EXTEND 12" BEYOND THE EDGE OF PAVING INTO PLANTING AREA. HAVE ENDS SEALED AND MARKED CLEARLY ABOVE GRADE. IN THE EVENT THAT THE CONTRACTOR FAILS TO INSTALL THE SLEEVES AS NOTED ABOVE, ANY ADDITIONAL WORK AND COSTS TO INSTALL THE SLEEVES FOLLOWING PAVEMENT INSTALLATION SHALL BE AT CONTRACTOR'S COST. REMOTE CONTROL VALVES: SET PRESSURE REGULATING MODULES TO 50 PSI FOR BUBBLER SYSTEMS. QUICK COUPLING VALVES: PROVIDE OWNER WITH ONE OPERATING KEY, TWO SETS OF LOCKING COVER KEYS, AND ONE HOSE SWIVEL. FIELD ADJUSTMENTS: SUBSTITUTIONS OF EQUIPMENT ARE NOT ALLOWED. ALL MATERIALS SHALL BE NEW AND INSTALLED IN A WAY THAT PROVIDES A COMPLETE AND EFFICIENT OPERATING SYSTEM. FIELD ADJUSTMENTS MAY BE REQUIRED TO PROVIDE OPTIMUM OPERATING EFFICIENCY -- THE CONTRACTOR SHALL BE RESPONSIBLE FOR CONTACTING THE CLIENT REPRESENTATIVE TO REVIEW PROPOSED FIELD ADJUSTMENTS PRIOR TO INSTALLATION. IF WRITTEN NOTIFICATION IS NOT RECEIVED AND RESPONDED TO BY THE CLIENT REPRESENTATIVE THE CONTRACTOR SHALL ASSUME FULL RESPONSIBILITY FOR ANY NECESSARY REVISIONS. L-2 NOTES: 1.WATERING TIMES ARE BASED ON WEEKLY APPLICATION RATES (IN INCHES). 2.THIS IRRIGATION SCHEDULE IS BASED ON A 8 HOUR WATERING WINDOW. THE IRRIGATION SYSTEM SHALL OPERATE BETWEEN 10 P.M. AND 6 A.M. 3.DURING THE LANDSCAPE ESTABLISHMENT PERIOD, INCREASE THE OPERATION RUN TIME BY 20%. 4.DUE TO UNFORESEEN SITE CONDITIONS AND WEATHER, THE IRRIGATION SYSTEM RUN TIMES MAY NEED TO BE ADJUSTED AS NECESSARY TO ENSURE THAT PROPER MOISTURE IS MAINTAINED IN THE LANDSCAPE. 5.WATERING TIMES ARE BASED ON ANNUAL EVAPOTRANSPIRATION OF 51.2 INCHES PER YEAR, IN ACCORDANCE WITH APPENDIX A OF THE MODEL WATER EFFICIENT LANDSCAPE ORDINANCE. 6.SET CONTROLLER SO FLOW THROUGH THE METER DOES NOT EXCEED 40 GPM.
