Division 04: Masonry submittal deviations
What changes between a Division 04 Masonry spec section and the sub's submittal, why it matters, and how each deviation is graded.
Short answer
Division 04 Masonry 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 04 covers masonry construction in commercial buildings: concrete masonry units (CMU), brick, stone, mortar, grout, reinforcing, and related accessories. Common CSI sections submitted for review:

The six deviation categories in Division 04 Masonry
Every issue Deviation Check flags maps to one of six categories. Here is how each appears in Division 04 Masonry 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.
Masonry specs name specific unit manufacturers, mortar producers, and accessory 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.

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 04 deviations are graded
Each finding is graded Blocker, Fix and Resubmit, or Note. Division 04 escalation rules:
- CMU compressive strength below spec f'm: BLOCKER (structural capacity per TMS 402)
- Brick grade below weathering requirement (MW where SW specified): BLOCKER (freeze-thaw durability)
- Mortar type below spec (Type N where Type S specified): BLOCKER (structural capacity and weather resistance)
- Grout strength below spec: BLOCKER (structural capacity for reinforced masonry)
- Reinforcing grade below spec: BLOCKER (structural per TMS 402)
- Missing fire rating documentation for rated assembly: BLOCKER (life-safety)
- Missing seismic compliance for reinforced masonry: BLOCKER (IBC)
- Wall tie type or spacing non-compliant with TMS 402: BLOCKER (structural connection of wythes)
- Through-wall flashing omitted where spec requires: BLOCKER (water infiltration, structural damage)
- CMU weight class mismatch (lightweight where normal weight specified for structural): BLOCKER if structural, FIX_AND_RESUBMIT if non-structural
- Brick color or texture mismatch: FIX_AND_RESUBMIT (aesthetic)
- Mortar joint profile mismatch: FIX_AND_RESUBMIT (aesthetic)
- Missing efflorescence test results: FIX_AND_RESUBMIT (quality assurance)

Frequently asked questions
What are the most common deviations in Division 04 Masonry 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 04 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).
