Engineering Term of the Month Quality Control
Quality control( QC) in construction is the process of measuring conformance with established requirements to ensure work is completed correctly. It involves the procedures, inspections, and corrective actions used to monitor the quality of materials, methods, and finished work, answering the question:“ Is the work done correctly?”
QC is carried out through planned activities that identify and correct deficiencies or nonconformance in construction. These include inspections, testing, and monitoring of workmanship, materials, and equipment. A clear quality control plan is essential and should define what will be inspected and the criteria for acceptable results. Conducting inspections during construction helps prevent costly repairs after completion.
Quality control works alongside quality assurance( QA). While QA establishes standards and expectations, QC focuses on the processes used to meet those standards.
In construction, QC ensures compliance with approved plans, specifications, and permit requirements. Under the International Building Code( IBC), this is supported through Special Inspections, which require independent, approved agencies to inspect critical structural elements such as steel, concrete, masonry, and soils. These inspections help ensure that construction meets required safety and performance standards.
Overall, quality control is essential for delivering a project that meets regulatory requirements and expected levels of quality.
