Division 05: Metals submittal deviations
What changes between a Division 05 Metals spec section and the sub's submittal, why it matters, and how each deviation is graded.
Short answer
Division 05 Metals submittals deviate most often on product substitutions, performance ratings, and missing certifications. Deviation Check flags every difference from the spec and grades it a Blocker, Fix and Resubmit, or Note.
Division 05 covers structural steel, miscellaneous metals, and ornamental metals in commercial construction. Common CSI sections submitted for review:

The six deviation categories in Division 05 Metals
Every issue Deviation Check flags maps to one of six categories. Here is how each appears in Division 05 Metals submittals, with the full guide one click away.
Manufacturer or Product Substitution
Blocker The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request.
Structural steel specs name fabricators, joist manufacturers, and deck suppliers. Look for:

Performance Specification Gap
Blocker A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

Missing Certification or Compliance Documentation
Fix and Resubmit A required listing, test report, certification, or compliance document is absent from the submittal package.
Required certifications in metals submittals:

Aesthetic Deviation
Fix and Resubmit A visible attribute (color, finish, texture, profile) differs from the spec or the architect-approved sample.

Detail or Installation Mismatch
Fix and Resubmit The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require.

Submittal Package Incompleteness
Fix and Resubmit A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted.

How Division 05 deviations are graded
Each finding is graded Blocker, Fix and Resubmit, or Note. Division 05 escalation rules:
- Steel grade below spec requirement: BLOCKER (structural capacity, building code)
- Bolt grade substitution (A325 where A490 specified): BLOCKER (connection capacity)
- Weld electrode understrength: BLOCKER (connection capacity)
- Missing AISC certification for fabricator: BLOCKER (IBC requirement for structural steel)
- Missing mill test reports: FIX_AND_RESUBMIT (traceability, required by spec and IBC)
- Metal deck gauge lighter than spec: BLOCKER (composite capacity, diaphragm capacity)
- Joist capacity below design loads: BLOCKER (structural)
- Missing AWS D1.8 compliance for seismic connections: BLOCKER (IBC seismic requirement)
- Missing special inspection plan: BLOCKER (IBC Chapter 17)
- Deflection limit exceeded: BLOCKER if structural/serviceability, FIX_AND_RESUBMIT if aesthetic
- Galvanizing thickness below ASTM A123 minimum: FIX_AND_RESUBMIT (durability)
- Fireproofing thickness below UL listing: BLOCKER (fire resistance rating)
- Railing height or picket spacing non-compliant with building code: BLOCKER (life-safety)

Frequently asked questions
What are the most common deviations in Division 05 Metals submittals?
The most common are product or manufacturer substitutions, performance specification gaps, and missing certification or compliance documentation. Deviation Check sorts every finding into one of six categories.
How are Division 05 deviations graded?
Each finding is graded Blocker (resolve before approval), Fix and Resubmit (correct and re-send before fabrication or install), or Note (acceptable with a comment).
