Steel Logistics — Wind Downtime Forecast
Wind Downtime Forecast for structural steel delivery and erection flow.
Wind downtime is forecastable from climate normals before the job starts — 12% of winter hours over a 14 m/s gust limit is a real number from a wind rose, not pessimism. Decking and panel work stops earlier than bare members; schedule the sail-area work for the calm season.
Formula
Note: Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.

About Steel Logistics — Wind Downtime Forecast
Steel Logistics — Wind Downtime Forecast computes the governing relationship lost = days × climatological %-over-limit live as you type. Wind downtime is forecastable from climate normals before the job starts — 12% of winter hours over a 14 m/s gust limit is a real number from a wind rose, not pessimism. Decking and panel work stops earlier than bare members; schedule the sail-area work for the calm season. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Steel Logistics — Wind Downtime Forecast
- 1Enter your values — Stop-work wind (gust), Hours over limit (climate), Planned erection days (sensible defaults are pre-filled).
- 2Read the live results: Expected lost days.
- 3Check the "with your numbers" line to see lost = days × climatological %-over-limit substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Steel Logistics — Wind Downtime Forecast?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula lost = days × climatological %-over-limit with authoritative sources cited on the page (AISC 303 — Code of Standard Practice for Steel Buildings)
- ✓Wind downtime is forecastable from climate normals before the job starts — 12% of winter hours over a 14 m/s gust limit is a real number from a wind rose, not pessimism.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
