The Most Frequently Missing Documents
The top omissions are remarkably consistent across project types and delivery methods.
- Current addenda — fabricators often provide the original bid set without incorporating addenda issued during design
- Division 05 specifications — the structural steel specification governs bolt grades, weld procedures, surface preparation, and inspection requirements
- Architectural reflected ceiling plans — required to determine cope depths at beam-to-column connections near finished ceilings
- Joist and deck drawings — needed to coordinate joist bearing seats, deck attachment, and framing member depths
- Connection load table or delegated design criteria — the single most RFI-productive missing document on any project
Why Addenda Are Particularly Costly to Miss
An addendum may revise a single column location or change a dozen connection types. If detailing proceeds from the original drawings, every item affected by the addendum requires revision when it's discovered — and those revisions often cascade into adjacent members. Track addenda by number and date; confirm with the PM that your package reflects all issued addenda before kickoff.
How to Confirm Your Package Is Complete
Before submitting to a detailing firm, run through a document checklist: structural drawings (IFC), addenda log, project spec Division 05, architectural drawings (floors and RCPs), MEP coordination drawings if BIM is required, joist and deck drawings, geotechnical report (if embeds are in scope), and your shop's standard connection details. A 15-minute document audit at package assembly saves three to four weeks of RFI cycle time during detailing.
