Performance Specification Gap in Division 14 Conveying Equipment submittals

By Deviation Check Editorial Team. Last reviewed June 1, 2026.

Short answer

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires. Default grade in Division 14 Conveying Equipment: Blocker.

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires. This guide covers how it shows up specifically in Division 14 Conveying Equipment submittals.

What to look for in Division 14 Conveying Equipment

Key performance parameters in Div 14 submittals:

  • Capacity (lbs) - passenger, service, freight, stretcher-service rated loads
  • Speed (fpm) - travel speed affects wait times, motor sizing, and shaft overhead requirements
  • Number of stops/openings - front and rear openings at each landing
  • Car interior dimensions (width x depth x height) - must meet ADA minimums and project requirements
  • Door opening width - 36" minimum for ADA, 42" or 48" for stretcher service
  • Door type - single-slide, center-opening, two-speed (affects opening time and width)
  • Motor horsepower (HP) - must match capacity and speed requirements
  • Machine type - geared traction, gearless traction, hydraulic (above-ground or in-ground cylinder)
  • Controller type - AC variable frequency drive, hydraulic valve (affects ride quality, energy use)
  • Travel distance - total rise from lowest to highest landing
  • Escalator step width - 24", 32", or 40" nominal (affects passenger throughput)
  • Escalator rise height - floor-to-floor vertical distance
  • Escalator speed - 100 fpm standard, 90 fpm for certain applications
  • Elevator door opening/closing time - code minimums per ASME A17.1
  • Leveling accuracy - +/- 1/4" for passenger elevators per code
  • Standby power operation - automatic transfer to generator, lowering capability

How severe is it?

Default grade: Blocker. Always a Blocker when the gap touches life-safety or structural performance.

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

Treat this as a hold. Do not approve the submittal until the sub resolves it, either by providing the specified product and documentation or by routing an approved substitution or or-equal request. Return the relevant spec passage to the sub as a redline.

Frequently asked questions

Which performance parameters in Division 14 Conveying Equipment submittals most commonly produce Blocker deviations?

Capacity in pounds, speed in feet per minute, and door opening width are the highest-stakes gaps. Door width is hard-coded by code - 36 inches minimum for ADA, 42 or 48 inches for stretcher service. Speed affects motor sizing and shaft overhead requirements, so a submittal showing a lower fpm than specified cannot simply be accepted as conservative. Leveling accuracy must hit plus or minus one-quarter inch per ASME A17.1.

How does an escalator speed or step-width discrepancy get evaluated in a Division 14 Conveying Equipment submittal review?

Step widths are fixed nominal sizes - 24, 32, or 40 inches - so any deviation directly affects passenger throughput and must match the spec exactly. Standard escalator speed is 100 fpm; some applications specify 90 fpm. A submittal showing the wrong step width or speed requires a revised product selection before fabrication begins, because the truss and pit dimensions are sized to the specific unit.
