CPM Schedule vs Lookahead Schedule
A CPM schedule models the overall project logic and critical path; a lookahead schedule translates near-term work into field coordination.
CPM Schedule
- Contract schedule control
- Critical path analysis
- Milestone forecasting
Lookahead Schedule
- Crew coordination
- Upcoming constraints
- Weekly field planning
Key differences
| Point | CPM Schedule | Lookahead Schedule |
|---|---|---|
| Time horizon | Whole project or major phase. | Usually the next few weeks. |
| Audience | Owner, contractor, scheduler, project controls. | Superintendents, foremen, trade partners. |
| Primary question | What controls completion? | What needs to happen next? |
Example in context
The CPM schedule shows the dry-in milestone is critical. The lookahead schedule coordinates framing, sheathing, inspections, and deliveries to protect that milestone.
