In the realm of construction, quality is of paramount importance. To ensure that projects meet the highest standards, Quality Assurance (QA) and Quality Control (QC) practices are implemented. This article aims to delve into the intricacies of QA/QC in construction, providing an expert and informative overview for the US region.

What is QA/QC in Construction?

QA/QC in construction refers to the comprehensive systems and processes employed to guarantee that projects conform to predetermined quality standards. It involves both proactive measures (QA) and reactive measures (QC) to maintain quality throughout the construction lifecycle. QA focuses on preventing defects and non-conformities, while QC emphasizes identifying and rectifying any issues that arise.

Quality Assurance (QA):

QA encompasses a range of activities conducted before and during the construction process. It involves meticulous planning, documentation, and implementation of quality management systems. Key aspects of QA include:

  1. Quality Planning: This phase involves establishing quality objectives, determining the necessary processes, and defining quality criteria. It entails identifying potential quality risks and developing mitigation strategies.

  2. Quality Control Procedures: QA entails the development and implementation of stringent control procedures, such as material testing, inspections, and audits.

Quality assurance is a method of avoiding potential mistakes in a construction project by creating 'rules' about minimum quality, while ensuring all decisions meet these standards.

What is the role of quality assurance in construction project?

QA helps construction project managers and stakeholders ensure that the construction that is being performed is compliant with the specifications set forth in the original plan. This could include testing of construction materials or components, verification of regularly scheduled maintenance, and more.

What does quality assurance do?

The quality assurance process helps a business ensure its products meet the quality standards set by the company or its industry. Another way to understand quality assurance (QA) is as a company's process for improving the quality of its products.

How do you perform quality assurance in construction?

5 Steps to improving Construction Quality Management Process
  1. Define and Share the Acceptance Criteria.
  2. Create an Inspection Plan.
  3. Use Checklists to Conduct Inspections.
  4. Correct Deficiencies and Verify Acceptance Criteria.
  5. Prevent Future Deficiencies.

Who is a QA on a construction site?

Quality assurance (QA) and quality control (QC) teams provide essential services to construction projects and ensure the final building or structure meets all client requirements. This step is essential to ensuring quality results that are likely to please the client.

What is an example of a quality assurance project?

Quality assurance examples
  • Manufacturing issues. Quality issues can frequently arise in manufacturing, and quality assurers monitor and help fix these problems before they cause damage.
  • Human error.
  • System improvements.
  • Process enhancements.
  • Design evaluation.
  • Food safety reviews.
  • Security improvements.
  • Analyse requirements.

How is quality assurance done?

Quality assurance utilizes one of three methods: Failure testing, which continually tests a product to determine if it breaks or fails. For physical products that need to withstand stress, this could involve testing the product under heat, pressure or vibration.

Frequently Asked Questions

Why is QAQC important in construction?

They help prevent errors, improve the quality of the project, reduce risks, increase customer satisfaction, and ensure the safety and efficiency of operations. QA focuses on preventing errors from occurring, while QC focuses on identifying and correcting errors.

What is QA and QC in project management?

Quality assurance and quality control (QC) have different definitions in project management. While quality assurance refers to the processes teams use to ensure quality deliverables, QC is an activity used to inspect and test the final project outputs.

What is an example of a QAQC?

Examples of quality assurance activities include process checklists, process standards, process documentation and project audit. Examples of quality control activities include inspection, deliverable peer reviews and the software testing process. You may like to read more about the quality assurance vs quality control.

What is the role of a QC?

Quality control inspectors remove or discard all products and equipment that fail to meet specifications. Quality control inspectors examine products and materials for defects or deviations from specifications.


What are QC projects?

QC is the process that ensures that materials used on the project actually comply with properly signed drawings and plans. Secondly, QC ensures that task-specific personnel actually perform construction project processes according to the specified QA standards.

Is QC a good career?

Job outlook and career prospects for QA and QC professionals

As of May 2021, the median annual salary for quality control inspectors is $38,580 [3]. This includes QC professionals in various industries, including manufacturing, wholesale trade, professional services, and scientific services.

What is QC stands for?

Quality control

Quality control (QC) is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. QC is similar to, but not identical with, quality assurance (QA).

What is the role of QA in construction?

Quality Assurance Specifies Standards, Quality Control Verifies Compliance To Standards. A successful QA program aims to ensure that the quality procedures implemented during the design phase of a construction project effectively meet the company-established standards for quality service, performance, and production.

  • What is difference between QA and QC?
    • QA primarily focuses on the processes and procedures that improve quality, including training, documentation, monitoring and audits. QC focuses on the product to find defects that remain after development. QC professionals find these issues in a variety of ways, including software testing and beta or canary testing.

  • What is difference between QA and QC in construction?
    • Quality Assurance (QA), refers to the implementation of proactive processes that aim to prevent defects. Quality Control (QC) simply refers to the process of inspecting the product to identify and correct defects.

  • Why is QC important in construction?
    • Most important of all, quality improvement can serve as a catalyst for improved productivity. By suggesting new work methods, by avoiding rework, and by avoiding long term problems, good quality control can pay for itself. Owners should promote good quality control and seek out contractors who maintain such standards.
