The Importance of QA/QC Documents in Construction & Common Documents of QA/QC Record

Quality assurance and quality control (QA/QC) are critical components of any construction project. These processes involve a series of measures and documentation that ensure the quality and consistency of the project. In this blog post, we will discuss some of the most common QA/QC documents found on construction sites.

A. Project Quality Plans

Project quality plans outline the specific quality procedures and standards that will be followed during the construction project. They are typically created at the beginning of the project and serve as a roadmap for quality control throughout the project.

B. Quality Procedures

Quality procedures are detailed instructions that outline how certain tasks or processes are to be performed. They ensure consistency and standardization in the execution of tasks, which helps to reduce the risk of errors and improve the overall quality of the project.

C. Inspection Test Plans (ITP)

Inspection test plans (ITP) provide a detailed description of the inspection and testing procedures that will be performed on the project. They outline the specific tests that will be conducted, the frequency of testing, and the personnel who will be responsible for conducting the tests.

D. Non Conformity Reports (NCR)

Non-conformity reports (NCR) document any deviations from the project quality plans or specifications. They are used to identify and document issues, and to track the progress of corrective actions.

E. Site Observation Reports (SOR)

Site observation reports (SOR) document any observations made by quality control personnel during construction. They are used to identify issues or non-conformities, and to track the progress of corrective actions.

Site Observation Reports (SOR), Non Conformity Reports (NCR), Welding Procedures (WPS&PQR)

F. Audits

Audits are used to evaluate the effectiveness of the quality management system. They are typically conducted by an independent third party and are used to identify areas for improvement and to ensure compliance with quality standards.

G. Calibration of Inspection, Measuring and Testing Equipments

Calibration is the process of adjusting and verifying the accuracy of inspection, measuring and testing equipment. It is essential to ensure that the equipment is providing accurate results, and it is typically done on a regular basis.

H. Welding Procedures (WPS&PQR)

Welding procedures (WPS) and procedure qualification records (PQR) are used to ensure the quality of welds. WPS provide guidelines for welding, and PQR are used to document the results of welding qualification tests.

I. Personnel Qualifications

Personnel qualifications documents the education, training and experience of the personnel working on the project. It is used to ensure that the personnel are qualified to perform their tasks and to meet project requirements.

J. NDT Reports

NDT (non-destructive testing) reports document the results of non-destructive testing procedures such as X-ray, ultrasonic, and magnetic particle testing. These reports are used to identify any defects or issues in the materials or structures being tested.

K. PWHT Reports and Charts

PWHT (post-weld heat treatment) reports and charts document the results of heat treatment procedures on welded joints. They are used to ensure that the joints have been properly heat treated and meet the necessary strength and ductility requirements.

L. Painting and Coating Reports

Painting and coating reports document the results of surface preparation, coating application, and inspection procedures. They are used to ensure that the surfaces have been properly prepared and coated to meet the necessary aesthetic and protective requirements.

M. Insulation Reports

Insulation reports document the results of insulation installation and inspection procedures. They are used to ensure that the insulation has been properly installed and is meeting the necessary thermal and acoustic requirements.

N. Fireproofing Reports

Fireproofing reports document the results of fireproofing installation and inspection procedures. They are used to ensure that the fireproofing materials have been properly installed and are meeting the necessary fire resistance requirements.


O. Mix Design and Trial Mixes

Mix design and trial mixes reports document the results of laboratory testing of concrete and mortar mixes. They are used to ensure that the mixes meet the necessary strength and durability requirements.

P. MAR

Material Acceptance Reports (MAR) document the results of inspections and testing of materials before they are used in the construction. They are used to ensure that the materials meet the necessary specifications and quality requirements.

Q. MRIR

Material Received Inspection Reports (MRIR) document the results of inspections and testing of materials upon delivery to the construction site. They are used to ensure that the materials meet the necessary specifications and quality requirements.

R. MTC

Material Test Certificates (MTC) are documents issued by the manufacturer or supplier of materials, certifying that the materials meet the necessary specifications and quality requirements. They are typically required for materials that must meet certain standards, such as structural steel or pressure vessels.


In conclusion, QA/QC documents are an essential part of any construction project. They ensure that the project is being built to the required standards and specifications, and they provide a record of the quality control processes that were followed throughout the project.
