Every set of construction documents tells a story. When that story has contradictions, missing chapters, or bad math, someone pays for it. Usually the architect.

QC checklists, redline reviews, and document review protocols are the structured defenses that prevent errors and omissions from reaching the field. They're not bureaucratic box-checking exercises. They're risk management tools that directly protect your license, your firm's finances, and your client's project.

A QC checklist forces reviewers to systematically examine every discipline and deliverable at each project phase, from schematic design through construction documents. Redline reviews create a documented trail of corrections, markups, and coordination notes that prove due diligence. Document review protocols establish who reviews what, when, and how findings get resolved.

For the PjM exam, you need to know more than the fact that these processes exist. You need to evaluate which review approach fits a given project scenario, recognize when a QC process has gaps, and judge whether a review protocol adequately addresses coordination risks. This topic connects directly to professional liability: firms with documented, consistent QC programs face fewer claims and can demonstrate standard-of-care compliance when disputes arise.

The difference between a firm that catches a structural-mechanical conflict at 60% DD and one that discovers it during construction? Usually a formal review protocol.
