Synthesis of Information Related to Highway Practices. Topic 52-06. Agency Use of Quality Control Plans for Administering Quality Assurance Specifications

Modern quality assurance (QA) specifications promoted by the Federal Highway Administration (FHWA) recognize the state departments of transportation’s (DOT’s) responsibility for monitoring the contractor’s quality control (QC) activities, conducting agency inspection, and conducting acceptance sampling and testing. Research and training focused on acceptance sampling and testing is currently available, and national, regional, and state certification programs have been developed to support those efforts. Research and training on reviewing the contractor’s QC plan and appropriate methods of DOT oversight of QC inspection and testing activities are more limited. QC plans are usually written by contractors and approved by DOTs, based on DOT requirements and specifications. Well-developed, proactive QC plans should be used to reduce process variability and prevent rework as well as to aid in delivering projects on-schedule and within budget. However, QC plans are often boilerplate or are developed only to be used to meet agency QC specification minimum requirements. Based on the historical quality of QC plans submitted, some DOTs have even stopped requiring QC plans to be submitted. Research has confirmed the importance of QA in transportation projects, and further research is needed in the areas of contractor QC, including adequate agency oversight of the QC plan. The objective of this synthesis is to document the various QC requirements used by DOTs, including how QC plans are reviewed, accepted, and monitored to achieve project specifications and what actions are being taken by an agency when QC plans are not being followed.
