Division 14 Conveying Equipment

Detail or Installation Mismatch in Division 14 Conveying Equipment submittals

Short answer

The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require. Default grade in Division 14 Conveying Equipment: Fix and Resubmit.

The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require. This guide covers how it shows up specifically in Division 14 Conveying Equipment submittals.

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)

How severe is it?

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

Deviation Check assigns a default per category and escalates or de-escalates based on the spec, always showing its reasoning. See the Division 14 severity rules.

What the PM should do

Stamp the submittal Revise and Resubmit. Mark the deviation, return the relevant spec passage as a redline, and have the sub correct and re-send before fabrication or installation.

Frequently asked questions

What hoistway dimension mismatches in Division 14 Conveying Equipment submittals can escalate from Fix and Resubmit to Blocker?

Any dimension mismatch that affects a seismic or structural assembly escalates to Blocker. Pit depth is the most common trigger - hydraulic and traction equipment have different pit requirements, and insufficient depth cannot be corrected after concrete is poured. Overhead clearance tied to travel speed is similarly structural. Rail bracket spacing that conflicts with the structural drawings also escalates because it involves the building frame.

How does a cab weight or electrical power supply discrepancy in a Division 14 Conveying Equipment submittal get corrected before installation?

Heavy cab interior finishes can push cab weight above the structural engineer's design assumptions for the counterweight and guide rail system, requiring a revised structural review before fabrication proceeds. Electrical power supply mismatches - voltage, phase, or amperage - must be reconciled with the electrical engineer so the feeder and disconnect are correctly sized. Both need written confirmation from the responsible engineer before the submittal can be approved.
