Attorneys and project stakeholders often use “schedule review” as a catch-all term, but a CPM review and a schedule integrity review answer different questions. Knowing which one a project needs, and when, can save significant time once a dispute begins. HPM Consultants provides both services to attorneys, owners, and contractors across San Diego, Los Angeles, San Francisco, and Orange County, where active construction markets generate frequent scheduling disputes on commercial and public projects alike.
What a CPM Review Evaluates
A CPM review examines the critical path method schedule itself: activity logic, durations, constraints, and how the critical path shifts across updates. Its purpose is to confirm the schedule is technically sound and reflects a realistic sequence of work, before that schedule becomes the basis for any delay or damages claim.
A CPM review typically checks:
- Whether logic ties are complete and reasonable
- Whether durations match the scope of each activity
- Whether the critical path is clearly identifiable
- Whether updates are internally consistent over time
These checks matter most while corrections are still possible, before a dispute forces the schedule into a fixed, unchangeable record.
What a Schedule Integrity Review Evaluates
A schedule integrity review goes a step further, testing whether the schedule can be trusted as evidence. It asks whether updates were made consistently, whether revisions are documented, and whether the schedule aligns with daily reports and correspondence.
This review is less about technical construction and more about credibility. A technically sound schedule that was reconstructed after a dispute began may still fail an integrity review, even if its logic checks out, because the sequence of updates itself becomes part of what opposing counsel will scrutinize.
When Each Service Provides the Most Value
A CPM review is most valuable early, while a project is active and a schedule can still be corrected before problems compound. A schedule integrity review becomes essential once a dispute is likely, since its findings speak directly to whether the schedule will hold up in litigation or arbitration.
For a San Diego construction damages expert witness building a claim, a reliable schedule integrity review often comes first, since damages calculations depend on a timeline that can withstand challenge. Skipping straight to a damages calculation without confirming the schedule’s reliability is one of the more common mistakes that weakens an otherwise strong claim.
