Schedule Management

A schedule that is built once and never re-baselined stops being a management tool within weeks of mobilisation. Disciplined schedule control means identifying the critical path, protecting its float, and updating the plan against actual progress on a fixed cycle.

Executive summary

Build a resource-loaded master schedule that integrates all contractors and long-lead procurement onto a single critical path, update it against actual progress at least monthly, and report float erosion to the steering committee before it becomes a delay claim. Reserve re-baselining for approved scope or schedule changes, not for absorbing uncontrolled slippage.

Why projects fail without this

  • Multiple contractor schedules exist but are not integrated into one master programme
  • Long-lead equipment procurement not visible as a schedule driver
  • Float consumed steadily without a corresponding management response
  • Schedule updates rely on contractor self-reported percentage complete without verification
  • History of schedule slippage discovered only at a milestone, not in progress
  • Commissioning window fixed by external factors, such as a plant shutdown or seasonal constraint

How disciplined teams run it

Integrated master schedule

Single critical-path programme combining all contractors, procurement and owner activities.

Resource-loaded scheduling

Links labour, equipment and material availability to schedule logic rather than dates alone.

Rolling wave updates

Near-term detail refined progressively while far-term activities remain at planning-level detail.

Recovery planning

Pre-agreed protocol for schedule recovery options — resequencing, added shifts, parallel working — triggered once float erosion crosses a threshold.

Risks and governance considerations

  • Contractor-reported percentage complete without independent verification tends to overstate progress in the middle of a project and understate it near completion
  • Float belongs to the project, not to any single contractor, and should be managed centrally rather than consumed by whichever party is behind
  • Re-baselining without a formal change order can mask genuine slippage as if it were planned
  • Long-lead procurement is frequently the true critical path on industrial projects, not the construction activities that receive the most attention

What to prepare

  • Integrated master schedule covering all contractors and procurement
  • Baseline schedule agreed and signed off before mobilisation
  • Progress verification method independent of contractor self-reporting
  • Float management protocol with escalation thresholds
  • Pre-agreed recovery options for schedule slippage scenarios

Frequently asked questions

How often should the master schedule be updated?

At least monthly, with critical long-lead items tracked more frequently; longer intervals allow slippage to compound before it is visible.

What triggers a formal re-baseline?

An approved scope or schedule change through governance, not accumulated informal slippage, which should instead trigger a recovery plan.

Is the construction phase usually the critical path?

Often not — long-lead equipment procurement and permitting frequently drive the critical path on industrial projects, and should be scheduled and tracked with equal rigour.
