# Detail or Installation Mismatch in Division 14 Conveying Equipment submittals

> Source: https://deviationcheck.com/divisions/14-conveying-equipment/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 14 Conveying Equipment

- **Hoistway dimensions** differ from manufacturer's required dimensions (pit depth, overhead clearance, shaft width/depth)
- **Pit depth** insufficient for specified equipment (hydraulic vs traction requirements differ)
- **Overhead clearance** insufficient for specified speed and code requirements
- **Machine room size** inadequate for specified equipment (or MRL specified but overhead machine room shown)
- **Rail bracket spacing** differs from structural drawings
- **Sill-to-sill dimension** at landings differs from manufacturer requirements
- **Cab weight** exceeds structural design assumptions (heavy interior finishes)
- **Electrical power supply** does not match specified motor requirements (voltage, phase, amperage)
- **Ventilation** - machine room cooling/ventilation capacity mismatch
- **Escalator truss support points** do not match structural design
- **Escalator pit dimensions** insufficient for specified unit
- **Landing configuration** mismatch (front/rear openings not coordinated with architectural plans)

## Severity

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