# Fixture Designations
This note details creation of fixture designations
for use in [[fixtures-takeoff]].
## Name Format
There is no standard convention
for fixture designation names
in the [[conest-body-of-knowledge]].
The best any estimator can do
is be internally consistent.
My own preference is similar to
`A - Surface (Pendant) = 2.0hrs - #12 MC+LV 20ft`,
described by the pseudo-[[regular-expression|regex]] below:
```regex
<phase-abbr> - <assembly>(: <assembly-subtype>)?( \(<comment>\))?( = <fixture-labor>)? <wiring-method> <branch-length>ft
```
### Phase Abbreviation (`<phase-abbr>`)
### Assembly (`<assembly>`)
[[luminaire-types]]
* "Surface" - Assembly includes a junction box
* "Recessed" - Assembly does not include a junction box
### Assembly Subtype (`<assembly-subtype>`)
### Comment (`<comment>`)
In contrast to Assembly Subtype,
Comment reflects a distinction between fixture types or use case
_which does not affect the contents of the designation._
That is, `Surface`, `Surface (Sconce)`, and `Surface (Pendant)`
### Fixture Labor (`<fixture-labor>`)
| Fixture Type | Labor |
|:------------ | ----------:|
| Paddle Fan | 1.5 hr/ea. |
| Pendant | 1-4 hr/ea. |
| Tape | 0.5 hr/6ft |
| Site Poles | 1.5 hr/ea. |
| Festoon | 2.0 hr/ea. |
| All Others | 1.0 hr/ea. |
`FIXTURES`/`FIXTURE LABOR`/`FIXTURE LABOR 1HR`
### Wiring Method (`<wiring-method>`)
#### Conduit/Cable Type
#### Wire Size
| Case | Wire Size |
| -------------- | --------- |
| Site/Courtyard | #10 |
| Garage | #10 |
| NM Cable | #14\* |
| All Others | #12 |
\*Minimum #12 in kitchens and bathrooms.
#### Dimming Conductors
### Branch Length (`<branch-length>`)
| Case | Standard Length |
| --------------------- | --------------- |
| Site/Courtyard | 50ft |
| Garage | 50ft |
| BOH | 40ft |
| Corridors | 40ft |
| Interior Amenity | 40ft |
| Office/Retail | 50ft |
| Exterior Amenity | 50ft |
| Units | 20ft |
| Undercabinet Fixtures | 10ft |
| Stairwells | 20ft |
| Kitchen | ? |
Reduce as appropriate.
## Order
Use empty designations to separate phases.
> [!example]
> ```
> # Stairwells
> BS - Surface = 1.0hrs - #12 EMT 20ft
> # Building
> ## Units - Key
> UK - Surface = 1.0hrs - #12 MC+LV 20ft
> UK - Surface = 1.5hrs - #12 MC+LV 20ft
> UK - Surface (Pendant) = 2.0hrs - #12 MC+LV 20ft
> UK - Surface (J-Box For Future Fixture) = 1.0hrs - #12 MC+LV 20ft
> UK - Recessed = 1.0hrs - #12 MC+LV 20ft
> _
> ## Units - Residential
> UR - Surface (Tape) = 1.0hrs - #12 MC+LV 25ft
> UR - Surface (Wall) = 1.0hrs - #12 MC+LV 25ft
> ...
> ```
## Content
## Garage
Use ENT assemblies unless forbidden by spec.
| Case | Subassembly Path (`FIXTURE ACCESSORIES`/`PVC/ENT ASSEMBLIES`/...) |
|:----------------- | ----------------------------------------------------------------- |
| Conventional Slab | .../`GARAGE FIXTURE ENT W/#10 - STEEL OCT RING` |
| Precast/I-Beam | .../`GARAGE FIXTURE W/T ROD ENT W/#10 - STEEL OCT RING` |
If PVC is required, use following assemblies:

|:------- |:----------------------------------------------------------------- |
| Ceiling | .../`... - SLAB BOX / 45 DEG STUBBY` |
| Wall | .../`... - STL BOX & TILE RING / 45 DEG STUBBY/ ENT DROP` |
## Surface Mount

| 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 1HR`
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|rule of thumb]] is
> * _12V strips:_ 5m (16.4ft)
> * _24V strips:_ 10m (32.8ft)
Separate these fixtures by labor, not length
```
*** Back of House ***
B - Surface (Tape) = 1.0hr (0-17ft) - #12 MC 40ft
_
*** Interior Amenity ***
IA - Surface (Tape) = 1.0hr (00-17ft) - #12 MC+LV 40ft
IA - Surface (Tape) = 2.0hr (18-29ft) - #12 MC+LV 40ft
IA - Surface (Tape) = 3.0hr (30-41ft) - #12 MC+LV 40ft
IA - Surface (Tape) = 4.0hr (42-53ft) - #12 MC+LV 40ft
IA - Surface (Tape) = 5.0hr (54-65ft) - #12 MC+LV 40ft
IA - Surface (Tape) = 6.0hr (66-77ft) - #12 MC+LV 40ft
IA - Surface (Tape) = 7.0hr (78-89ft) - #12 MC+LV 40ft
