Expert-defined terms from the Certificate in Construction Quality Assurance course at LearnUNI. Free to read, free to share, paired with a professional course.
Acceptance Criteria #
Acceptance Criteria
Explanation #
The documented conditions that a product, service, or process must satisfy before it is deemed acceptable. Example: A concrete slab must achieve a compressive strength of 35 MPa within 28 days. Practical application includes using the criteria to guide final inspections. Challenges arise when criteria are vague or conflict with client expectations.
Audit #
Audit
Explanation #
A systematic, independent examination of quality processes to verify conformity with standards and internal procedures. Example: Conducting a quarterly ISO 9001 audit of subcontractor documentation. Audits help identify gaps, but they can be resource‑intensive and may cause resistance if perceived as punitive.
Baseline Schedule #
Baseline Schedule
Explanation #
The approved project schedule against which performance is measured. It includes key milestones, critical path activities, and allocated durations. In practice, baseline schedules support progress tracking; however, frequent changes can erode their usefulness and complicate variance analysis.
Benchmarking #
Benchmarking
Explanation #
Comparing an organization’s processes or outcomes with industry leaders to identify improvement opportunities. For instance, measuring defect rates against national averages. Benchmarking drives continuous improvement but requires reliable data and may overlook contextual differences.
Bill of Quantities (BQ) #

Change Management #
Change Management
Explanation #
The process of identifying, evaluating, approving, and documenting changes to project scope, schedule, or quality requirements. A formal change request for additional waterproofing is an example. Effective change management minimizes disruption, yet uncontrolled changes can degrade quality and inflate budgets.
Client Requirements #
