  16. QUALITY ASSURANCE & INSPECTION SUCCESS STORY OF QA&I QA&I HAS A VERY SPECIAL SIGNIFICANCE IN NTPC’s SUCCESS. NTPC ANALYSED THE REASONS OF POOR PERFORMANCE OF POWER PLANTS IN THE COUNTRY AND ENVISAGED MANY STATE OF THE ART MANAGEMENT CONCEPTS.

  17. QUALITY ASSURANCE & INSPECTION SUCCESS STORY OF QA&I NTPC’S EXPERIENCE OF PLAYING A COMPLEMENTARY ROLE WITH THE EQUIPMENT MANUFACTURER IN ENSURING THE QUALITY OF EQUIPMENT HAS BEEN WELL PROVEN AND DIRECTLY REFLECTS IN THE “ RELIABILITY AND AVAILABILITY “ OF THE POWER PLANTS

  18. QUALITY ASSURANCE & INSPECTION FEATURES THAT MAKE QA&I EFFECTIVE • INVOLVEMENT OF QA&I AT EVERY STAGE AS AN INTEGRATED APPROACH TO ASSURE QUALITY. • IN BUILT CHECKS AND BALANCES ENSURE EFFECTIVE CONTROLS. • SOME UNIQUE FEATURES OF NTPC QA&I SYSTEM ARE ELABORATEDAHEAD.

  19. QUALITY ASSURANCE & INSPECTION RELIBILITY CHAIN“ANY CHAIN IS AS STRONG AS THE WEAKEST LINK “ • LINKS OF THE CHAIN ARE : • RIGHT AND PROVEN TECHNOLOGY • RIGHT EQUIPMENT • RIGHT SOURCES • RIGHT MANUFACTURING PROCESS • RIGHT SYSTEMS - MANUFACTURING QUALITY - FIELD QUALITY IN BOTH ERECTION / CONSTRUCTION AND O&M PHASE

  20. QUALITY ASSURANCE & INSPECTION ENSURING HEALTHY LINKS RELIABILITY BY SYSTEM APPROACH • ENGINEERING • QUALITY SYSTEMS • CONTRACTUAL PROVISIONS • INSPECTION • FIELD QUALITY - IN ERECTION / CONSTRUCTION - IN OPERATION & MAINTENANCE

  21. QUALITY ASSURANCE & INSPECTION UNIQUE FEATURES SYSTEMS’ APPROACH • PREAWARD TIE -UPS • POST AWARD TIE-UPS

  22. QUALITY ASSURANCE & INSPECTION UNIQUE FEATURES • PRE-AWARD TIE-UPS : • QA REQUIREMENTS IN TECHNICAL SPECIFICATION. • EVALUATION OF BIDS w.r.t. QA REQUIREMENTS. • TIE-UP OF QA REQUIREMENTS DURING PRE-AWARD. • FINALISATION OF LIST OF ITEMS REQUIRING QP AND SUB-VENDOR APPROVAL.

  23. QUALITY ASSURANCE & INSPECTION CQA ROLE IN SPECIFICATION FINALISATION AND PRE-AWARD AGREEMENT QA REQUIREMENTS IN MODULAR SPECIFICATION VALIDATION FOR PACKAGE CONTRACTSPECIFICATION C Q A E N G G BID EVALUATION BID EVALUATION REPORT (I) LIST OF ITEMS REQUIRING QP AND SUB-VENDOR APPROVAL (II) QA&I CO-ORDINATION PROCEDURE (III) SUB-VENDOR ASSESSMENT PROCEDURE (IV) QUALITY AUDIT REQUIREMENTS PRE-AWARD AGREEMENT WITH IDENTIFIED VENDORS/ MAIN CONTRACTORS FEEDBACK OF SUB-VENDOR PERFORMANCE BY RIO / SITE TO CS & FORM PART OF LOA ANALYSIS OF PREVIOUS NON-CONFORMITIES (NCRs)

  24. QUALITY ASSURANCE & INSPECTION UNIQUE FEATURES P0ST-AWARD • APPROVAL OF QUALITY PLANS. • INSPECTION AND CHP CLEARANCE SYSTEM. • DEVIATION DISPOSITIONING SYSTEM. • MDCC LINKED TO RELEASE OF PAYMENT

QUALITY ASSURANCE & INSPECTION BEST PRACTICES IN QA &I • WELL DEFINED VENDOR ASSESSMENT SYSTEM • STANDARDISATION • REVIEW & APPROVAL OF QUALITY PLANS THROUGH DREAMS SOFT WARE AND FORWARDING TO CONTRACTORS BY E-MAIL. • RECIVING INSPECTION CALLS THROUGH INTERNET AND GENERATING CHP AND MDCC THROUGH WINDSOR X SOFT WARE.

  33. BEST PRACTICES IN QA&I • SYSTEM OF FEEDBACK • QUALITY SYSTEM AUDITS OF MANUFACTURERS / SUPPLIERS AND PROJECTS SITES. • PREPARATION OF TRAINING CALANDER TO CATER NEEDS OF QA,FQA AND INSPECTION EXECUTIVES, • ISO 9001-2000 CERTIFICATION TO ALL INSPECTION OFFICES AND CQA

  34. QUALITY ASSURANCE & INSPECTION BEST PRACTICES • SUB-VENDOR ASSESSMENT SYSTEM AT NTPC, FOR BOUGHT OUT ITEMS SUB-VENDORS ARE ACCEPTED BASED ON MAIN CONTRACTOR’S PROPOSAL ON PACKAGE TO PACKAGE BASIS AS PER TECHNICAL SPECIFICATION REQUIREMENTS. AS SUCH, AT PRESENT, THERE IS NO SYSTEM OF SUB-VENDOR REGISTRATION OR ENLISTMENT. DETAILS OF EARLIER ASSESSED SUB-VENDOR IS KEPT IN THE FORM OF SUB-VENDOR FILES. VENDOR ASSESSMENT IS CARRIED OUT FOR SUB-VENDORS IDENTIFIED IN “DR’ (DETAILS REQUIRED ) CATEGORY DURING PRE-AWARD WITH MAIN CONTRACTOR.

  35. QUALITY ASSURANCE & INSPECTION BEST PRACTICES • STANDARDISATION • MODULAR AUTOMATED TECHNICAL SPECIFICATION • FINALISATION OF “REFERENCE QUALITY PLAN” & STANDARD QUALITY PLAN” • MODEL LIST OF ITEMS REQUIRING QP APPROVAL AND SUB-VENDOR APPROVAL • INCORPORATION OF QA REQUIREMENTS IN “STANDARD CHECK-LISTS” PREPARED BY PROJECT ENGINEERING FOR DRAWING & DATA-SHEET APPROVAL

  36. QUALITY ASSURANCE & INSPECTION BEST PRACTICES SYSTEM OF FEEDBACK • THE FEEDBACK OF INSPECTION IS USED FOR UPGRADATION OF QA REQUIREMENTS AND TIE-UPS FOR FUTURE PROJECTS • DEVIATION DISPOSITIONING DURING MANUFACTURING / ERECTION AT SITE NOT ONLY ENSURES PROPER RESOLUTION TO THE PROBLEM BUT ALSO PROVIDES FEEDBACK FOR FUTURE WORK. • FEEDBACK FROM OPERATING UNITS IS ALSO ANALYSED AND TAKEN INTO ACCOUNT FOR FUTURE PROJECTS.

  37. QUALITY ASSURANCE & INSPECTION BEST PRACTICES • QUALITY SYSTEM AUDITS QUALITY SYSTEM AUDITS OF MANUFACTURING UNITS OF REGULAR SUPPLIERS W.R.T REQUIREMENTS OF ISO & OTHER QUALITY SYSTEM MANUALS IS TAKEN UP . ALSO, QUALITY SYSTEM AUDIT OF NTPC PROJECT SITES W.R.T. NTPC FQA MANUAL & CONSTRUCTION MANUAL IS TAKEN UP. FOLLOW UP FOR NECESSARY CORRECTIVE AND PREVENTIVE ACTION IS MADE BY CQA.
