Who is responsible for quality assurance under the QC/QA Program?

In the context of a Quality Control/Quality Assurance (QC/QA) Program, the responsibility for quality assurance typically lies with the organization overseeing the project, which in this case is the Illinois Department of Transportation (IDOT). IDOT's role encompasses the establishment of standards and procedures to ensure that the materials and work performed meet specified requirements.

IDOT's involvement includes conducting reviews and inspections, testing materials, and ensuring compliance with the design specifications. This level of oversight helps to promote high-quality outcomes in construction projects, aligning with public safety and engineering standards. Quality assurance from this authority ensures an unbiased review of the construction methods and materials used, facilitating a transparent and accountable process.

While contractors are responsible for the quality control of their work, the overarching accountability for quality assurance in this program rests primarily with IDOT, making their role crucial in maintaining the integrity of the project. This distinction highlights the importance of having a governing body that can enforce compliance and uphold standards across multiple contractors and subcontractors involved in a project.
