Structural and Connection Errors
The most serious rejection reasons relate to structural compliance:
- Connection type does not match EOR's structural drawings — e.g., detailer used a shear tab where EOR specified a moment connection
- Connection geometry that cannot develop the required load capacity — weld size undersized, insufficient bolt rows
- Seismic detailing that does not comply with AISC 341 — missing continuity plates, incorrect weld access holes, non-prequalified connection geometry
- Material grades not matching the specification — A36 plate used where A572-50 was specified
- Missing stiffeners or doubler plates called for on the structural drawings
Scope and Completeness Issues
EORs frequently reject submittals because entire scope items are missing:
- Members shown on structural drawings but not included in the submittal package
- Anchor bolt plans submitted without the column base plate details
- Miscellaneous steel in scope but not submitted
- Required connection calculations not included when delegated design was specified
- IFC model required but not submitted
Drawing Quality and Format Issues
Even technically correct drawings get rejected if they cannot be efficiently reviewed:
- Drawing scale too small to verify hole patterns and dimensions
- Revision block not current — shows old revision letter or date
- Missing piece marks on individual members within an assembly
- Weld symbols missing or incomplete
- Reference dimensions shown without working dimensions (the EOR cannot verify compliance without seeing actual dimensions)
