COMMISSION INTERNATIONALE DES GRANDS BARRAGES ------- VINGT-SIXIÈME CONGRÈS DES GRANDS BARRAGES Autriche, juillet 2018 ------- KEY NOTES ON QUALITY CONTROL OF ROLLER COMPACTED CONCRETE DAMS HAMED. MAHDILOUTORKAMANI Quality Control Engineer, Uma Oya Multipurpose Project Development FARAB COMPANY IRAN 1. INTRODUCTION[1, 2] Roller compacted concrete dam (RCC) construction, including preparation of RCC materials, construction procedures and testing during construction is put into the framework of quality concepts. When put into this framework, the designer and contractor can see the integrated nature of both design and construction processes to achieve project quality objectives that result in safe and cost effective dam construction. Quality concepts, particularly quality assurance (QA) and quality control (QC) are defined as follows: Quality assurance (QA) is a program covering activities necessary to provide quality in work, and to ensure that activities that require good quality are being performed effectively. QA specifies actions necessary to provide enough confidence that the project will satisfy the given requirements as established in e.g. design criteria and performance specifications. Quality control (QC) is the specific implementation of the QA program and includes the monitoring and evaluation of processes and outcome against the requirements and specifications. QC has to facilitate the immediate application of actions to the outcome, thus, allowing the engineer to exert direct influence on the outcome. 1504
