What Is the Best Way to Compare Planned and Actual Construction Schedules?
A dependable way to compare planned and actual construction schedules is to save a baseline with the planned start and end of each phase, record the actual dates as work happens and calculate the variance for every phase and project.
In Jestor, planned and actual dates live side by side, and dashboards show where schedules slip.
Why are schedule comparisons rarely done?
Schedules are updated as the project moves, and the original plan is overwritten. At the end, nobody knows how far the project drifted.
Without the comparison, the company keeps making the same estimating mistakes.
Clients also ask for evidence of schedule performance.
What problems does schedule comparison solve?
- Original plans overwritten and lost
- No measure of schedule performance
- Repeated estimating errors
- Weak evidence in client discussions
- Late detection of drifting phases
How do I compare schedules in Jestor?
- Save baseline dates for each phase when the plan is approved.
- Record actual start and end dates as work happens.
- Calculate variance in days with formula fields.
- Highlight phases with large variance.
- Compare projects on a dashboard of schedule performance.
| Field | Purpose |
|---|---|
| Planned start and end | Baseline |
| Actual start and end | Real progress |
| Variance in days | Delay or advance |
| Delay cause | Root cause analysis |
How do I use variance in future projects?
Phases that always run late need longer estimates or better preparation.
Using real durations from past projects makes new plans more reliable.
Why use Jestor for schedule comparison?
- Baseline and actual dates: both kept on each phase.
- Variance formulas: delays calculated automatically.
- Gantt view: current schedule visible to everyone.
- Portfolio dashboards: schedule performance across projects.
What else helps you compare planned and actual construction schedules?
- Linking variance to delay causes completes the picture, showing not only how late a phase was, but why.
- Sharing schedule performance with clients can also build trust. Explaining variances with data and causes shows professionalism and reduces tension when a phase runs late.
- The same data supports internal reviews at the end of each project.
This is how you compare planned and actual construction schedules and plan better next time.
