## The six deviation categories in Division 14 Conveying Equipment

### Manufacturer or Product Substitution (default grade: Blocker)

The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request.

Div 14 specs typically name a single elevator or escalator manufacturer. Substitutions carry significant coordination risk because hoistway dimensions, pit depths, overhead clearances, and structural loads are manufacturer-specific. Look for:
- Elevator manufacturer substitutions (Otis, KONE, Schindler, thyssenkrupp, Mitsubishi Electric, Fujitec)
- LULA/accessibility lift manufacturer substitutions (Savaria, Garaventa, Symmetry, Federal Elevator)
- Wheelchair lift manufacturer substitutions (Garaventa, Savaria, National Wheel-O-Vator, Ascension)
- Escalator manufacturer substitutions (Otis, KONE, Schindler, thyssenkrupp, Mitsubishi Electric, Fujitec)
- Controller/drive system substitutions (proprietary OEM vs third-party - Virginia Controls, MCE, etc.)
- Cab interior vendor substitutions (Eklund's, G&R Custom Elevator Cabs, Snap Cab, Tyler Elevator)
- Door operator substitutions (GAL Manufacturing, Wittur, proprietary OEM)

### Performance Specification Gap (default grade: Blocker)

A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

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

### Missing Certification or Compliance Documentation (default grade: Fix and Resubmit)

A required listing, test report, certification, or compliance document is absent from the submittal package.

Required certifications in Div 14 submittals:
- **ASME A17.1/CSA B44** compliance (Safety Code for Elevators and Escalators - the primary governing standard)
- **ASME A17.2** inspection guide compliance documentation
- **ASME A18.1** compliance for wheelchair lifts and LULA elevators
- **ADA/ICC A117.1** accessibility compliance (car size, controls, signals, door timing)
- **UL listing** for controllers, power units, and electrical components
- **Seismic provisions** per ASCE 7 and ASME A17.1 Seismic Requirements (where required by jurisdiction)
- **NFPA 72** interface documentation (firefighters' emergency operation - Phase I recall, Phase II operation)
- **NFPA 13** compliance for sprinkler protection in hoistways and machine rooms
- **IBC Chapter 30** compliance documentation
- **State elevator code** compliance (varies by jurisdiction - some states adopt A17.1 with amendments)
- **Structural load data** for architect/engineer (machine room loads, hoistway reactions, pit loads)
- **Electrical load data** for electrical engineer (motor FLA, feeder size, disconnect requirements)

### Aesthetic Deviation (default grade: Fix and Resubmit)

A visible attribute (color, finish, texture, profile) differs from the spec or the architect-approved sample.

- Cab interior finishes (wall panels - stainless steel type/finish, laminate, stone, wood veneer)
- Cab ceiling type (LED downlights, suspended panel, fan with light)
- Cab flooring material and pattern (spec may require owner's finish - coordinate thickness)
- Entrance/door finish (satin stainless, mirror stainless, painted, bronze, antique)
- Handrail type and finish inside cab
- Signal fixture style (hall lanterns, position indicators, car operating panel design)
- Signal fixture finish (faceplates - stainless, bronze, painted to match wall)
- Hall call button style and finish
- Escalator balustrade type (glass, stainless steel, solid)
- Escalator handrail color (black standard - colored is a specification item)

### Detail or Installation Mismatch (default grade: Fix and Resubmit)

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

- **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)

### Submittal Package Incompleteness (default grade: Fix and Resubmit)

A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted.

Commonly required items in Div 14 specs:
- Layout drawings (plan view of hoistway, pit, overhead, machine room)
- Elevation drawings showing all openings and travel
- Structural load reactions (for structural engineer review)
- Electrical power requirements (for electrical engineer review)
- Cab interior finish samples or detailed drawings
- Signal fixture samples or cut sheets (hall lanterns, COP, hall stations)
- Door operator and entrance details
- Controller and drive system specifications
- Firefighters' emergency operation sequence narrative
- Seismic design calculations (where required)
- Maintenance and warranty terms
- Escalator truss layout and support point reactions
- ADA compliance checklist covering car size, controls height, door timing, signals

## How Division 14 deviations are graded
