QA and QC differ mainly in their cost structures. QA prevents defects before they happen, while QC detects existing problems.<h3>Prevention Costs vs Detection Costs</h3>Prevention-based quality assurance needs higher upfront investments. Studies show that every dollar spent on prevention saves $10 in correction costs and $100 in failure costs. Companies save money by avoiding expensive rework and material waste.Quality control costs include:<ul class="list-bullet"><li value=1>Inspection and testing expenses</li><li value=2>Rework and scrap material costs</li><li value=3>Product verification procedures</li><li value=4>Documentation of defects</li></ul>Prevention costs through QA save more money over time. Companies that use strong QA processes spend nowhere near as much on internal failure costs, which can reach 10-15% of revenue when quality problems surface.<h3>Labor Hours: QA vs QC Teams</h3>QA managers create quality procedures, training programs, and preventive measures. They also develop inspection checklists and hold regular team meetings to explain quality requirements.QC teams focus on physical inspections and testing during construction. They perform scheduled checkpoint examinations and document any defects in detailed reports. QC officers must also oversee material replacements and fixes when problems come up, which adds to labor hours.Modern construction management platforms reduce labor requirements for both approaches. To cite an instance, Cortex&#39;s construction drawing software streamlines document management and quality tracking processes. This cuts down administrative hours for both QA and QC teams.Labor allocation changes based on choosing QA or QC. QA teams work proactively and spend more time planning and preventing issues. They create documentation and procedures for each building section. QC teams handle issues as they come up. They conduct tests and manage corrections throughout the project&#39;s lifecycle.
