# Detail or Installation Mismatch in Division 31 Earthwork submittals

> Source: https://deviationcheck.com/divisions/31-earthwork/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 31 Earthwork

- **Tieback spacing** differs from shoring design drawings (changes tributary load per anchor)
- **Soldier pile embedment depth** below excavation subgrade differs from design (affects passive resistance)
- **Geogrid overlap dimensions** at connections and boundaries - spec typically requires minimum 12-24 inches
- **Compaction lift thickness** differs from spec maximum (typically 8-12 inches per lift for granular, 6-8 inches for cohesive)
- **Geotextile overlap** at seams - spec typically requires 12-24 inches; stapled seam vs sewn seam requirements
- **SWPPP best management practices** proposed differ from approved plan (inlet protection type, silt fence placement, stabilization method)
- **Drainage composite overlap** at joints - most products require minimum 6-inch lap
- **Dewatering discharge location** differs from approved SWPPP or stormwater permit

## Severity

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