The six deviation categories in Division 32 Exterior Improvements

Every issue Deviation Check flags maps to one of six categories. Here is how each appears in Division 32 Exterior Improvements 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.

Site improvement specs frequently name brand products or approved manufacturers. Look for:

Performance Specification Gap

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

Key performance parameters in exterior improvement submittals:

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 exterior improvement submittals:

Aesthetic Deviation

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

Common in exterior improvements - highly visible to owners and public:

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 32 deviations are graded

Each finding is graded Blocker, Fix and Resubmit, or Note. Division 32 escalation rules:

• Asphalt binder grade (PG) lower than climate zone and traffic requirement: Always BLOCKER (premature rutting or thermal cracking - pavement will fail prematurely)
• Concrete paving f'c below spec: BLOCKER (structural adequacy of parking/drive surface)
• Concrete air content below ACI 301 minimum for freeze-thaw exposure: BLOCKER in cold climates (scaling and spalling failure)
• Athletic surface Gmax above 200g per ASTM F355: Always BLOCKER (user safety - head impact injury threshold)
• Missing stormwater authority approval where impervious area threshold is crossed: BLOCKER (regulatory - cannot pave without permit)
• Plant caliper below specified ANSI Z60.1 size: FIX_AND_RESUBMIT (contractual requirement; owner paid for specified size)
• Unapproved plant species substitution: FIX_AND_RESUBMIT (owner decision required; not a contractor unilateral call)
• Asphalt air voids outside 3-5% target range in mix design: FIX_AND_RESUBMIT (durability impact but not immediate structural failure)
• Irrigation DU below 0.70 for turf zones: FIX_AND_RESUBMIT (water waste and uneven coverage; increasingly regulated by water districts)
• Missing synthetic turf third-party test report: FIX_AND_RESUBMIT (manufacturer data alone does not satisfy spec)
• Pavement section thickness below geotech recommendation: BLOCKER (premature structural failure)
• Fencing post embedment depth below spec: FIX_AND_RESUBMIT unless in high-wind/security zone, then BLOCKER
• Missing asphalt mix design from certified lab: FIX_AND_RESUBMIT (cannot verify conformance without it)

Run a Division 32 submittal review

Upload a Division 32 spec section and your submittal package before you send it, and get a one-page deviation report in under five minutes, so the package goes through the first time. GC reviewers use it the same way on a package that just arrived. Before that, work through the free Division 32 checklist.
