Fixture Designations
This note details creation of fixture designations for use in fixtures-takeoff.
Naming
Format
<phase-abbr> - <assembly>(\: <subtype>)?( - <fixture-labor>)? \(<wiring-method>\)( <wm-descriptor>)* <branch-length>ft
[!example]
A - Surface: Pendant - 2.0hrs (MC) LV 20ft
Order
Use empty designations to separate phases.
[!example]
*** Hotel Units *** HU - Surface = 1.0hrs - #12 MC+LV 20ft HU - Surface = 1.5hrs - #12 MC+LV 20ft HU - Surface: Pendant = 2.0hrs - #12 MC+LV 20ft HU - Surface: J-Box For Future Fixture = 1.0hrs - #12 MC+LV 20ft HU - Recessed = 1.0hrs - #12 MC+LV 20ft *** Condo Units *** CU - Surface: Tape = 1.0hrs - #12 MC+LV 25ft CU - Surface: Wall = 1.0hrs - #12 MC+LV 25ft

Garage
Fixtures
Use ENT assemblies unless forbidden by spec.
FIXTURE ACCESSORIES/PVC/ENT ASSEMBLIES/GARAGE FIXTURE ENT W/#10 - STEEL OCT RING
FIXTURE ACCESSORIES/PVC/ENT ASSEMBLIES/GARAGE FIXTURE W/T ROD ENT W/#10 - STEEL OCT RING
Use threaded rod assemblies in I-beam/precast garages.
If PVC is required, use following assemblies:
| Case | Assembly Path |
|---|---|
| Ceiling | FIXTURE ACCESSORIES/PVC/ENT ASSEMBLIES/... - SLAB BOX / 45 DEG STUBBY |
| Wall | FIXTURE ACCESSORIES/PVC/ENT ASSEMBLIES/... - STL BOX & TILE RING / 45 DEG STUBBY/ ENT DROP |
Homeruns
System= "EL - Electrical"
Use 1 Homerun for every 3 circuits in Garage
Use assembly COMMON ASSEMBLIES/Device Homeruns in Slab/Deck

| PVC in Ceiling | PVC/ENT ASSEMBLIES/... - SLAB BOX / 45 DEG STUBBY |
| PVC in Wall | PVC/ENT ASSEMBLIES/3/4" PVC W/ 3#12 - STL BOX/TILE RING |
| EMT | EMT ASSEMBLIES/... - SQ BOX & ROUND P RING |
Note
Use lighting control cable assemblies in Amenity areas
Tape Lighting
Also called "cove" or "strip" lighting, however those terms are less specific and potentially confusing.
Use item FIXTURE LABOR 1/2HR
and change Fct 1 to match the calculated labor
(1 hour per 12 feet).
Note
Tape lighting length is limited by the "max power length" of the model (usually measured in millimeters). Max power length is usually 5000-15000mm (~16-49ft) depending on luminous output and voltage.
A reasonable heuristics is
- 12V strips: 5m (16.4ft)
- 24V strips: 10m (32.8ft)
Separate these fixtures by labor, not length
*** Back of House ***
B - Surface: Tape = 0.5hr (01-06ft) - MC #12 40ft
B - Surface: Tape = 1.0hr (07-12ft) - MC #12 40ft
