COMMON WORK FOR VALVES AND PIPES

GENERAL PIPING SYSTEMS TESTING REQUIREMENTS.

PRIOR TO ACCEPTANCE OF WORK, TEST PIPING SYSTEMS IN THE PRESENCE OF THE DDS REPRESENTATIVE AND AUTHORITIES HAVING JURISDICTION PER RESPECTIVE AND APPLICABLE GOVERNING CODES AND REQUIREMENTS OF THIS SECTION. CONDUCT TESTS PRIOR TO CONCEALING PIPING. BACKFILL BURIED PIPING TO EXTENT REQUIRED TO PREVENT MOVEMENT.

PROVIDE NECESSARY EQUIPMENT AND MATERIALS AND MAKE NECESSARY TEST CONNECTIONS REQUIRED TO PROPERLY EXECUTE TESTS.

OBTAIN WATER FROM POINT(S) DESIGNATED BY THE DDS REPRESENTATIVE. PROMPTLY REMOVE TEMPORARY CONNECTIONS UPON COMPLETION OF TESTING OR WHEN DIRECTED BY THE DDS REPRESENTATIVE.

REMAKE LEAKING GASKET JOINTS WITH NEW GASKETS AND NEW FLANGE BOLTING. DESTROY OLD BOLTING. WHERE WELDED JOINTS FAIL, SUBMIT PROPOSED METHOD OF REPAIR FOR APPROVAL BY THE DDS REPRESENTATIVE. TESTING SHALL TAKE PLACE DURING STEADY STATE AMBIENT TEMPERATURE CONDITIONS.

OTHER THAN STANDARD PIPING FLANGES, PLUGS, CAPS AND VALVES, USE ONLY COMMERCIALLY MANUFACTURED EXPANDABLE ELASTOMER PLUGS FOR SEALING OFF PIPING FOR TEST PURPOSES. THE SAFE TEST PRESSURE RATING OF ANY PLUG SHALL BE NOT LESS THAN TWO TIMES THE ACTUAL TEST PRESSURE BEING APPLIED. DO NOT USE EXPANDABLE ELASTOMER PLUGS FOR PIPING WHICH COULD DEVELOP SUFFICIENT REACTIVE FORCE TO CAUSE DAMAGE TO A STRUCTURE, OTHER PIPING, OR CAUSE MOVING OF THRUST OR ANCHOR PROVISIONS IN CASE OF BLOW-OUT.

REMOVE COMPONENTS FROM PIPING SYSTEMS DURING TESTING WHENEVER THE COMPONENT MAY SUSTAIN DAMAGE TIE TO TEST PRESSURE OR TEST MEDIA. AFTER COMPLETION OF THE TEST, REINSTALL THE COMPONENT AND RETEST AT THE COMPONENT PRESSURE RATING WITH SUITABLE MEDIA.

CHECK SYSTEM COMPONENTS SUCH AS VALVES FOR FUNCTIONAL OPERATION UNDER SYSTEM TEST PRESSURE. DO NOT ADD TEST MEDIA TO A SYSTEM DURING A TEST FOR A PERIOD AS SPECIFIED OR TO BE DETERMINED BY DDS REPRESENTATIVE.

PREPARE AND MAINTAIN RECORDS OF PIPING SYSTEMS TESTS. RECORD DATES, TEST GAUGE IDENTIFICATION NUMBERS, AMBIENT TEMPERATURE, PRESSURE RANGES, RATES OF PRESSURE DROP AND LEAKAGE RATES.

THE CONNECTIONS BETWEEN NEW UNDERGROUND PIPING AND THE EXISTING SHALL NOT BE SEPARATELY TESTED. PRESSURE SPECIFIED IN GOVERNING CODE SHALL BE MAINTAINED ON THE JOINT FOR NOT LESS THAN 30 MINUTES.

IN THE EVENT TESTING DEMONSTRATES LEAKAGE RATES IN EXCESS OF SPECIFIED LIMITS, DETERMINE SOURCE(S) OF LEAKAGE, REPAIR OR REPLACE DEFECTIVE MATERIALS AND WORKMANSHIP AND RETEST INSTALLATION UNTIL COMPLIANCE WITH SPECIFIED REQUIREMENTS.

CLEANING AND FINISHING

UPON COMPLETION OF WORK IN EACH RESPECTIVE AREA, CLEAN AND PROTECT WORK. JUST PRIOR TO FINAL ACCEPTANCE, PERFORM ADDITIONAL CLEANING AS NECESSARY TO PROVIDE CLEAN EQUIPMENT AND AREAS TO THE DDS REPRESENTATIVE.

SUBMITTALS:

SHOP DRAWINGS AND PRODUCT DATA GROUPED TO INCLUDE COMPLETE SUBMITTALS OF RELATED SYSTEMS, PRODUCTS, AND ACCESSORIES IN A SINGLE SUBMITTAL TO DDS REPRESENTATIVE.

PROJECT/SITE CONDITIONS

INSTALL WORK IN LOCATIONS SHOWN ON DRAWINGS, UNLESS PREVENTED BY PROJECT CONDITIONS.

PREPARE DRAWINGS SHOWING PROPOSED REARRANGEMENT OF WORK TO MEET PROJECT CONDITIONS, INCLUDING CHANGES TO WORK SPECIFIED IN OTHER SECTIONS. OBTAIN PERMISSION OF DDS REPRESENTATIVE BEFORE PROCEEDING.

EXAMINE RELATED WORK AND SURFACES BEFORE STARTING WORK OF ANY SECTION:

REPORT TO DDS REPRESENTATIVE, IN WRITING, CONDITIONS WHICH WILL PREVENT PROPER PROVISION OF THIS WORK.

BEGINNING WORK OF ANY SECTION WITHOUT REPORTING UNSUITABLE CONDITIONS TO DDS REPRESENTATIVE CONSTITUTES ACCEPTANCE OF CONDITIONS.

FIT MATERIALS AND EQUIPMENT TO OTHER PARTS OF EQUIPMENT AND STRUCTURE.

CAUSE AS LITTLE INTERFERENCE OR INTERRUPTION OF EXISTING UTILITIES AND SERVICES AS POSSIBLE.

KEEP ROADS CLEAR OF MATERIALS AND DEBRIS.

DETERMINE AND VERIFY LOCATIONS OF ALL EXISTING UTILITIES ON OR NEAR SITE.

PROVIDE NECESSARY PERMITS, LICENSES, AND INSPECTIONS.

DRAWINGS

DRAWINGS IN GENERAL ARE DIAGRAMMATIC AND INDICATE SIZES, LOCATIONS, CONNECTIONS TO EQUIPMENT AND METHODS OF INSTALLATION.

SCALED AND FIGURED DIMENSIONS ARE APPROXIMATE.

BEFORE PROCEEDING WITH WORK CHECK AND VERIFY ALL DIMENSIONS.

DIMENSIONS INDICATED ARE LIMITING DIMENSIONS.

AS BUILT DRAWINGS

INCLUDE ALL FIELD CHANGES, ADJUSTMENTS, VARIANCES, SUBSTITUTIONS AND DELETIONS, INCLUDING ALL CHANGE ORDERS.

EXACT LOCATION, TYPE, AND FUNCTION OF CONCEALED VALVES, AND PIPING.

EXACT SIZE, INVERT ELEVATIONS AND LOCATION OF UNDERGROUND AND UNDER FLOOR PIPING AND VALVES.

TRANSPORTATION AND HANDLING FOREIGN MATTER.

SHIP EQUIPMENT IN ORIGINAL PACKAGE, TO PREVENT DAMAGING OR ENTRANCE OF FOREIGN MATTER.

SPECIAL TOOLS

FURNISH TO DDS REPRESENTATIVE AT COMPLETION OF WORK:

SIX SETS OF ANY SPECIAL TOOLS REQUIRED TO OPERATE, ADJUST, DISMANTLE OR REPAIR EQUIPMENT FURNISHED UNDER ANY SECTION OF THIS DIVISION.

"SPECIAL TOOLS": THOSE NOT NORMALLY FOUND IN POSSESSION OF MECHANICS OR MAINTENANCE PERSONNEL.

ONE PRESSURE GREASE GUN FOR EACH TYPE OF GREASE REQUIRED:

WITH ADAPTERS TO FIT ALL LUBRICATING FITTINGS ON EQUIPMENT.

INCLUDE LUBRICANT FOR LUBRICATED PLUG VALVES.

PROTECTION OF MATERIALS

MATERIAL, EQUIPMENT OR APPARATUS DAMAGED BECAUSE OF IMPROPER STORAGE OR PROTECTION WILL BE REJECTED. REMOVE FROM SITE AND PROVIDE, NEW, DUPLICATE, MATERIAL EQUIPMENT OR APPARATUS IN REPLACEMENT OF THAT REJECTED.

REVIEW OF CONSTRUCTION

WORK MAY BE REVIEWED AT ANY TIME BY DDS REPRESENTATIVE.

ADVISE DDS REPRESENTATIVE THAT WORK IS READY FOR REVIEW AT FOLLOWING IMES:

PRIOR TO BACKFILLING BURIED WORK.

PRIOR TO SYSTEM TESTS.

WHEN ALL REQUIREMENTS OF CONTRACT HAVE BEEN COMPLETED.

NEITHER BACKFILL NOR CONCEAL WORK WITHOUT DDS REPRESENTATIVE'S CONSENT.

NOISE REDUCTION

COOPERATE IN REDUCING OBJECTIONABLE NOISE OR VIBRATION CAUSED BY MECHANICAL SYSTEMS.

CORRECT NOISE PROBLEMS CAUSED BY FAILURE TO INSTALL WORK IN ACCORDANCE WITH CONTRACT DOCUMENTS.

GUARANTEE

GUARANTEE ALL NEW WORK LABOR AND MATERIAL FOR ONE FULL YEAR FROM THE END OF THE PROJECT CONSTRUCTION.ALL NEW WORK GUARANTEE ALSO APPLIES TO SERVICES INCLUDING INSTRUCTIONS, ADJUSTING, TESTING, NOISE, BALANCING, ETC.

EQUIPMENT MANUFACTURERS SHALL INCLUDE FULL COVERAGE DURING WARRANTY PERIOD.

TRENCHING, EXCAVATION AND BACKFILL

TRENCHING AND EXCAVATION

MINIMUM DEPTH:

SAME AS THE EXISTING PIPE DEPTH. PIPE DEPTH VARIES AT DIFFERENT LOCATIONS.

EXCAVATE TO BELOW BOTTOM OF PIPING AS REQUIRED TO INSTALL NEW VALVE MEETING REQUIREMENTS SHOWN IN THE DETAILS ON DRAWINGS.

REFILL WITH WELL TAMPED SAND AND GRAVEL.

BACKFILLING:

IMMEDIATELY AFTER PIPING INSTALLED, INSPECTED, TESTED AND ACCEPTED.

REMOVE SHEET PIPING AND BRACING.

BACKFILL AROUND PIPING WITH SPECIAL CARE TO SOLIDLY FILL VOIDS WITHOUT INJURY TO PIPING.

BACKFILL MATERIAL:
