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
