 Difference between quality assurance and quality control in construction.

Difference between quality assurance and quality control in construction.

During the course of daily construction operations, contractors sometimes interweave the concepts of Quality Assurance with the concepts of Quality Control. Since the two are indeed responsive one to another, it seems only natural to lump them into a single process. Yet confusing the two is error.

Unless both owner and employees correctly apply the distinctions between construction project QA and construction project QC, construction firms will endure difficulty in ensuring high-quality results from the construction process. These two individual components of quality management are not mutually interchangeable. Each serves a specific set of processes, goals and purposes. In order that fieldworkers, operators, management and subs effectively execute established construction project quality standards, they must work within the boundaries of their role within the structure of the quality program.

Quality Assurance provides planned system of review and spot  check by DAB staff.One step review process before each submission.Quality Assurance happens after Quality Check is complete.Quality Assurance review frequency is per the Quality Management Plan

Quality control provides 100% of checking documents, plan, etc..Quality Control is a detailed process for each submittal with multiple steps.Quality Control is done throughout the life of the project.Quality Control review happens on all projects and submittals
