The Schedules module turns a static Gantt into a living plan. Critical path computes itself, the field works from real lookaheads, and every slip shows up the day it happens — not at handover.
A schedule built like an operating system. Purpose-built for general contractors, ErectOS runs the master schedule as live infrastructure — computing the critical path, briefing the field, and reporting the truth every single day.
A real CPM engine underneath. Forward and backward pass on every change, float tracked task by task.
ErectOS watches every slip, delivery, and approval — and flags what it means before it costs the finish date.
Lookaheads your supers actually run. Progress flows back from the daily log, not the Friday meeting.
Sequence the job with real dependencies, milestones, and crew loads. The moment anything changes, the longest chain to substantial completion recalculates — and every downstream date moves with it.
1.0 Plan
Duct delivery slipped 3 days — MEP Rough-In float is gone. It now drives the finish date.
Pull Drywall — north wing forward 4 days. Recovers the Oct 5 finish.
Roll the master down into a 3-week lookahead your supers and trades work from. Every commitment carries its constraints, so blockers get cleared before the crew shows up — not after.
2.0 Field
Rebar trucks confirmed for Thu 6am — staging at gate 3.
Good. That clears L2 rough-in for week 25.
Set a baseline at contract and track every variance against it. Planned vs earned progress at a glance, with a forecast completion date that moves with real field data — not optimism.
3.0 Track
Cedar Heights is 9 days behind baseline.
Baseline revision BL-3 drafted — awaiting owner approval.
Schedules reads from and writes to every module it touches — the plan and the project never drift apart.
Field progress posts straight to % complete. The Gantt updates the night the work happens.
Approved COs push their schedule deltas automatically — the slip is priced before it is absorbed.
Crew assignments drive resource load on the plan, so leveling reflects who is actually on site.
Schedule slip feeds cost forecasts and completion dates the moment it appears.
The schedule updates itself. The field just builds.
