# Detail or Installation Mismatch in Division 32 Exterior Improvements submittals

> Source: https://deviationcheck.com/divisions/32-exterior-improvements/detail-installation-mismatch/

The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require.

## What to look for in Division 32 Exterior Improvements

- **Pavement section thickness** - base + surface course total must match geotechnical pavement design recommendation; shortchanging base is a common substitution
- **Asphalt surface course thickness** differs from spec (e.g., 2" spec, submittal shows 1.5")
- **Concrete joint spacing** differs from spec maximum (typically 10-15 ft for 4" slab; exceeding joint spacing increases cracking risk)
- **Curb reveal height** differs from spec or ADA requirements at transitions
- **Irrigation head spacing** does not match precipitation rate calculations (head-to-head coverage required for specified DU)
- **Plant spacing** differs from landscape plan requirements (affects coverage at maturity)
- **Tree pit size** below spec minimum (typically 3x root ball diameter for B&B)
- **Fencing post embedment depth** differs from spec minimum (typically 1/3 of total post height plus 6")
- **Bike rack or bollard anchor bolt pattern** differs from manufacturer's base plate template
- **Rubberized track thickness** per lane differs from spec (affects Gmax rating)

## Severity

Default grade: Fix and Resubmit. Escalates to Blocker when the difference affects a fire-rated, seismic, or structural assembly.
