ACG Quality Handbook

PREFACE Asset Creation Group (ACG) was created in Distribution projects under NR T&D CAPEX. H conforming to the quality standards and guideli of this handbook is to create a document on the Electrical, Mechanical, Substations-Projects, H quality write-ups for their respective wings whic The handbook contains activity wise Quality A wings separately. It has a total of 21 nos. QAP been vetted by M/s. Bureau Veritas. They were QAP format and suggest changes/ modific incorporated in this handbook. The finalized documents have also b departmental Preparer, Issuer and Approvers of the respective QAPs. We hope, these QAPs and QCCs will serve as a reference document and time, it will be a record for future, which will be subject to yearly revision fo Sujit Kumar Pathak General manager Construction Department

the year 2010 to ensure timely and quality execution of Substation and Historically, the department, like the other departments of CESC, has been ines of execution which were not laid down till date. The primary objective e subject. To make it happen, each wing of the department, namely, Civil, HT-Projects and HT-Construction, has taken the initiative to prepare the ch have finally been collated and published in this handbook. Action Plan (QAP) and Quality Control Checklist (QCC) for each individual P and 30 nos. QCC. The QAP documents prepared by the department has e given the scope to peruse the contents of all the QAPs, standardize the cations/ additions/ alterations as necessary, which have finally been been signed by the auditing company as the Reviewer alongside the d guideline to all the officers & employees of the department. At the same or necessary updation and control.













1. INTRODUCTION This Quality Handbook has been prepared as a general guideline for the Q Civil, Electrical, Mechanical, Substations-Projects, HT-Projects and HT-C this manual are based on the Company Guidelines, Technical Standards, The contract documents take precedence over this Manual and in the e charge/Undersigned for any clarification. Users of this manual are invited to submit comments or to suggest cha changes, if appropriate, may be incorporated into future revisions. 1

Quality Control of various types of works executed by different wings (i.e., Construction) of Asset Creation Group (ACG). The Checklists included in Departmental SOPs and Best Work Practices, etc. event of any perceived conflict reference is to be made to the Project-in- anges. These should be directed to the Technical CFT of ACG, so that ____________________ GENERAL MANAGER CONSTRUCTION DEPARTMENT 1

2. PURPOSE AND SCOPE 2.1 GENERAL The purpose of this document is to provide a structured approach to Qu works are being carried out in accordance with the requirements of the Sp Contractor is carrying out adequate surveillance a suite of checklists hav execution activities and are intended to be used on a daily basis during su These checklists are seen as the first stage of development of the Quality manual as Specifications are reviewed and incorporated in the system. For Project Works, specific QAP(s) along with responsibility matrix in lin Project-in-Charge. It is to be mutually agreed upon and jointly signed by Execution-in-charge before starting of the activities. Any third-party quality audit will be an addition to the set Quality Action P and/or the Execution-in-charge 2.2 REFERENCES As noted above the checklists form an integral part of Quality Contr Documentation for the project. Other documentation that will need to be re • Special Conditions of Contract • Construction Drawings • The Contractors Work Method Statements and Quality Control Doc • Material Data Sheet • Relevant Standards 2.3 RESPONSIBILITIES In accordance with Quality Actions Plans attached herewith, the Executio staff delegated with this responsibility will use the checklists included completed on a regular basis, preserved at site and submitted along w Execution-in-charge. 2

uality Control of various works executed by ACG and to ensure that the pecification. In order to do this and provide documentary evidence that the ve been prepared. These checklists form the backbone of surveillance of upervision of the works. y Control Manual and further Checklists are envisaged to be added to the ne with those attached herewith is to be prepared under the guidance of y the Contractor’s Representative, Third Party Quality Auditor (if any) and Plan and it will not reduce the scope of Quality Checks by the Contractor rol and the completed checklists will form the majority of the Quality eferred to will included: cumentation on-in-charge will delegate responsibilities for surveillance of the work. The in this document as an aid to inspecting the works. Checklists will be with the Work Measurement Sheet during Progressive/Final Billing to the 2
