Construction Schedule Health Checklist
Use this construction schedule-health checklist to review P6 logic, constraints, calendars, progress, critical path, milestones and reporting readiness.
Discuss Your Project →This checklist is a practical first review—not a substitute for tracing the actual construction logic and milestone paths in the schedule.
Logic
Check missing predecessors and successors, excessive lags, redundant ties, relationship types and whether the sequence matches field execution.
Constraints and Calendars
Confirm that constraints have a documented purpose, calendars reflect actual work rules and imposed dates are not masking the CPM calculation.
Durations and Float
Review unusually long activities, high float, negative float and near-critical paths. Thresholds should prompt investigation, not automatic deletion.
Progress Quality
Look for actual dates after the data date, out-of-sequence work, zero remaining duration on incomplete activities and unsupported changes to remaining duration.
Critical Path Credibility
Trace the path to key contractual milestones. Confirm that the path contains real work, procurement and turnover—not only constraints or artificial logic.
Management Usefulness
Make sure the file can produce clear lookaheads, milestone forecasts, responsibility views and a concise explanation of what needs attention.
