CLARK COUNTY DEPARTMENT PUBLIC WORKS Construction Management QUALITY PROGRAM QUALITY CONTROL QUALITY ASSURANCE INDEPENDENT ASSURANCE QUALITY --Quality Control is the responsibility of the primary installer or fabricator of the material; they are the experts in what they build. --Quality Assurance is the oversight by the agency of the Quality Control; they want to receive what is specified. Uses verified QC testing and inspection as acceptance (like when observing the production of a car you want to buy ) --Independent Assurance is the responsibility of the agency to ensure QA and QC are verifiable Make sure QC and QA testing are compatible and consistent Contractor Quality Control Sections 111 thru 117 and website 111 Administration- General Gives overview of program Check to see Responsible Person in Charge and Quality Control Coordinator; both required or only one See exceptions (inspector separate from foreman) Contractor responsible for the Quality of the work.
