Steel Logistics — Fit-Up Error Cost
Fit-Up Error Cost for structural steel delivery and erection flow.
A misfit found at the hook costs ten times the same error caught at the fab shop's QC bench — the crane waits while someone reams, files an NCR or sends the piece back. Survey-verified anchor bolts and a real shop-dimension audit are the cheap inputs to this number.
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.
