Worked out by this tool from its default inputs. Its role plan lets you run your own numbers, print the sheet and save it.
Path A is critical: finishes Nov 23, 2026 (Nov 30, 2026 with weather), milestone Nov 27, 2026
- Critical path
- Path A: 26 days
- Path B total float
- 4 days (length 22)
- Path C total float
- 10 days (length 16)
- Project float to milestone
- 4 days spare
Milestone dates
- Start
- Oct 17, 2026; first working day Oct 19, 2026, working 5 days a week
- Critical path (Path A) finishes
- Nov 23, 2026 after 26 working days
- With the weather allowance
- Nov 30, 2026 (5 working days added)
- Contract milestone
- Nov 27, 2026 (30 working days from the start)
- Float to the milestone
- 4 working days; after weather 1 working day short
- Verdict
- Tight: the critical path fits, but the weather allowance would make it 1 working day late

- What if Path B slips 6 working days · 3 lines, starting with “Float that absorbs it”

The plain-words read of this example
Path A is the critical path at 26 working days: starting Oct 17, 2026 it finishes Nov 23, 2026, against a milestone of Nov 27, 2026. Tight: the critical path fits, but the weather allowance would make it 1 working day late. If Path B slips 6 working days, its float absorbs 4 working days and the critical path moves 2 working days, leaving the job 5 calendar days late. That costs $7,500.00 in liquidated damages, charged per calendar day, plus $6,600.00 in general conditions. Crash it: $9,000.00 to gain 3 working days against $14,100.00 in damages and general conditions. Give written notice of any excusable delay within 10 days.
