CORPORATE QUALITY ASSURANCE
CORPORATE QUALITY ASSURANCE AND INSPECTION IS UNDER ENGINEERING DIVISION LOCATED AT NOIDA , HAVING A STAFF OF 66 ( 53 : QUALITY ASSURANCE + 13 : INSPECTION ). QUALITY ASSURANCE IS HAVING DIFFERENT GROUPS OF MECH., ELECT.+ C&I, CIVIL AND SPECIALIST GROUP.

QUALITY ASSURANCE & INSPECTION

REGIONAL INSPECTION OFFICES
TO FACILITATE PROMPT INSPECTION AT MANUFACTURE’S WORKS , APPROX. 86 ENGINEERS ARE POSTED AT 10 STRATEGICALLY LOCATED REGIONAL INSPECTION OFFICES SPREAD THROUGHOUT THE COUNTRY. MAJOR EQUIPMENTS FOR POWER PLANTS ARE MANUFACTURED AT BHEL WORKS, HENCE, FIVE OF THESE INSPECTION OFFICES FUNCTION AS RESIDENT INSPECTION OFFICES AT BHEL’S UNIT AT HARDWAR, TRICHY, RANIPET, HYDERABAD AND BHOPAL. REST OF THE RIOs ARE LOCATED AT KOLKATA, MUMBAI, CHENNAI, BANGLORE, DELHI, THIS ENABLES PROMPT INSPECTION AT MANUFACTURER’S WORKS AT DIFFERENT STAGES.

QUALITY ASSURANCE & INSPECTION

FIELD QUALITY ASSURANCE
ALL TWENTY THREE PROJECTS OF NTPC (INCLUDING NTPC MANAGED PROJECTS) ARE HAVING FIELD QUALITY ASSURACE GROUPS, EACH HAVING STRENGTH OF THREE TO NINE EXECUTIVES. THIS GROUP IMPLEMENTS QA MANAGEMENT SYSTEM FOR ERECTION AS WELL AS O&M RELATED ACTIVITIES.

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.

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

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 EFFECTIVE CONTROLS. BALANCES ENSURE

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 EMAIL. ? RECIVING INSPECTION CALLS THROUGH INTERNET AND GENERATING CHP AND MDCC THROUGH WINDSOR X SOFT WARE.

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

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 SUBVENDOR REGISTRATION OR ENLISTMENT. DETAILS OF EARLIER ASSESSED SUB-VENDOR IS KEPT IN THE FORM OF SUB-VENDOR FILES. VENDOR ASSESSMENT IS CARRIED OUT FOR SUBVENDORS IDENTIFIED IN “DR’ (DETAILS REQUIRED ) CATEGORY DURING PRE-AWARD WITH MAIN CONTRACTOR.

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

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.

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.
