The relationship between tolerances and construction method implies what about quality control?

• A. Tolerances are independent of method
• B. Tolerances help determine permissible variation, impacting methods
• C. Tolerances only affect finishing time
• D. Tolerances replace quality control inspections

Answer: (B)

Tolerances set the allowable variation from the planned dimensions, and the construction method determines whether those variations can be achieved in practice. Quality control uses those limits to decide what to measure, how often to inspect, and what corrective actions are acceptable. If you’re aiming for tight tolerances, the method must provide the level of precision required—through precise formwork, steady consolidation, accurate alignment, and controlled curing—so QC can confidently verify that the results stay within spec. If the tolerances are looser, the QC plan can be less stringent, but inspections are still necessary to confirm compliance. Tolerances guide, not replace, quality control, and they affect more than just finishing time by influencing overall dimensional and surface quality.
