Monthly schedule update governance

Operate a repeatable cutoff, status, change, calculation, review, response, and approval cycle.

Working definition

A controlled update cycle aligns field evidence, the native schedule, schedule narrative, management reports, and formal decisions to one reporting cutoff. Roles and deadlines are established before the period closes so status is not reconstructed after the schedule is calculated.

Key takeaways

  • Set the cutoff, evidence, roles, and deadlines before status collection.
  • Compare each update with both prior update and baseline.
  • Tie comments, responses, corrections, and final disposition to the native file.
01

One cutoff, one package

Daily reports, quantity records, progress photos, procurement and submittal logs, change records, and schedule status should reconcile to the same cutoff. Preserve late corrections as transparent revisions rather than silently moving evidence between periods.

02

Review deltas, not only the latest picture

Compare with the prior accepted update and the baseline. Separate progress, forecast changes, logic revisions, calendar edits, duration changes, constraints, added or deleted scope, and coding changes.

Operate the monthly schedule cycle

Tailor days and roles to the contract while preserving the sequence.

Before you start

    1. Close the period

      Confirm cutoff, data date, required records, status owners, and open changes.

      Verify: Every data source identifies the same reporting period.

    2. Collect and reconcile status

      Validate actuals, progress, remaining durations, procurement, submittals, change events, and field constraints.

      Verify: Material status has named evidence and owner confirmation.

    3. Build and quality-check

      Update the controlled native file, run the schedule, compare changes, and prepare narrative and quality reports.

      Verify: The package is internally consistent before submission.

    4. Review and respond

      Issue evidence-linked comments, receive itemized responses, and verify corrections in the revised native file.

      Verify: No comment closes on narrative assurance alone.

    5. Publish the disposition

      Record accepted, accepted with conditions, revise and resubmit, or rejected status and retain the complete package.

      Verify: The project record identifies the controlling update for the next cycle.

      Field-ready control

      Monthly operating cycle

      • Cutoff and data date aligned
      • Status evidence complete
      • Remaining work reforecast
      • Changes separately logged
      • F9 log retained
      • Prior and baseline comparisons complete
      • Narrative reconciled
      • Comments and responses linked
      • Final disposition recorded

      Common questions

      Should the owner edit a contractor’s submitted schedule to fix it?

      The reviewer should preserve the submitted native file and normally issue findings for correction. Any analytical copy should be clearly identified and never substituted for the contractor’s authored record.
