Direct Answer
A steel delivery schedule is a document listing planned delivery dates, truck load contents (by assembly mark), and sequence for all fabricated steel to the job site. It is developed collaboratively with the erection contractor to ensure deliveries match the erection sequence — steel arrives when the ironworkers are ready for it, not before (causing site storage problems) or after (causing crew idle time).
Full Explanation
Key elements of a delivery schedule: (1) Delivery number — each truck load or delivery group gets a number. (2) Planned delivery date and window (time of day). (3) Assembly marks included on each delivery. (4) Approximate weight and truck configuration. (5) Site access requirements (crane position, road clearances). For multi-story buildings, deliveries are typically sequenced by erection tier. For industrial projects, sequenced by system (column lines, then main framing, then secondary). The schedule should have 1–2 week lookahead updates shared weekly with the erector.
What This Means for Your Shop
A well-coordinated delivery schedule eliminates site storage issues. Steel that arrives too early piles up on site, gets mixed with other deliveries, and slows the sorting process for the ironwork crew. Delivering 3–5 days ahead is ideal — enough buffer to avoid crew idle time if fabrication is slightly delayed, but not so much that you're creating a site storage problem.
Common Mistakes
Delivering all steel in the first two weeks of a 12-week erection schedule because your shop 'finished early.' The erector can only set what the crane can reach and what connections are in sequence — a full site of premature deliveries creates chaos.
Recommended Process
Build the delivery schedule with the erection foreman 3–4 weeks before first delivery. Review and update weekly. Communicate any delivery changes (late or early) at least 48 hours in advance so the erector can adjust crane and crew planning.
