# Fixture Designations
This note details creation of fixture designations
for use in [[fixtures-takeoff]].
[[luminaire-types]]
## Naming
### Format
```regex
<phase-abbr> - <assembly>(\: <assembly-subtype>)?( \(<comment>\))?( = <fixture-labor>)? <wiring-method> <branch-length>ft
```
> [!example]
> `A - Surface (Pendant) = 2.0hrs - #12 MC+LV 20ft`
### 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
### 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. |
### Fixture 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.
### Fixture Branch Wire size
| Case | Wire Size |
| -------------- | --------- |
| Site/Courtyard | #10 |
| Garage | #10 |
| NM Cable | #14[^1] |
| All Others | #12 |
[^1]: Minimum #12 in kitchens and bathrooms.
## Garage
Use ENT assemblies unless forbidden by spec.
| Case | Assembly 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:
| Case | Assembly Path (`FIXTURE ACCESSORIES`/`PVC/ENT ASSEMBLIES`/...) |
| ------- | -------------------------------------------------------------- |
| Ceiling | .../`... - SLAB BOX / 45 DEG STUBBY` |
| Wall | .../`... - STL BOX & TILE RING / 45 DEG STUBBY/ ENT DROP` |
## Surface Mount
> [!info] Surface Mount Fixtures
> * Wall Mount
> * Wall Pack
> * Sconce
> * Swing Arm
> * Pendant
> * Linear
> * Tape
> * Track
| Wiring Method | Assembly Path |
| -------------- | ----------------------------------------------------------- |
| NM Cable | `NM ASSEMBLIES`/`RND BOX BAR HNGR...` |
| MC Cable | `MC ASSEMBLIES`/`SQ BOX, ROUND P RING & MNTG BRKT...` |
| 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|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) - MC #12 40ft
_
*** Interior Amenity ***
IA - Surface (Tape) = 1.0hr (00-17ft) - MC+LV #12 40ft
IA - Surface (Tape) = 2.0hr (18-29ft) - MC+LV #12 40ft
IA - Surface (Tape) = 3.0hr (30-41ft) - MC+LV #12 40ft
IA - Surface (Tape) = 4.0hr (42-53ft) - MC+LV #12 40ft
IA - Surface (Tape) = 5.0hr (54-65ft) - MC+LV #12 40ft
IA - Surface (Tape) = 6.0hr (66-77ft) - MC+LV #12 40ft
IA - Surface (Tape) = 7.0hr (78-89ft) - MC+LV #12 40ft
```
## Recessed

| MC Cable | `MC ASSEMBLIES`/`HI HAT - ...` |
For crowded puck light areas:
measure length between fixtures,
round up to the nearest 5ft
> [!note]
> "HI HAT" refers to a recessed can fixture.
## Undercabinet Fixtures
| Wiring Method | Assembly Path |
| ------------- | ------------------------------------- |

## Stairwells & Elevators
`PVC/ENT ASSEMBLIES`/`... - SLAB BOX / 45 DEG STUBBY`
## Facade
> * `Phase` = "Facade"
Length and Labor will be more than a normal fixture in BOH/Amenity
| Fixture Type | Labor |
| ------------ | ---------------------- |
| Non-Linear | 2hrs |
| Linear | See [[#Tape Lighting]] |
> 1. `3/4" PVC W/ 3#10 - STL BOX & TILE RING / 45 DEG STUBBY/ ENT DROP`
> * `Length per Unit` = Distance to panel
## Porte Cochere (Drive up Area)
Create its own breakout in WBS, and phase in Accubid
> [!quote]
> This is not technically exposed or drop ceiling, but still use PVC
## Site & Courtyard
> [!important]
> Coordinate with landscape drawings
### Breakdowns
> * `System` = "FML - Site Fixtures Material & Labor"
### Pole Lights
> [!info] Takeoff
> 1. `FIXTURE ACCESSORIES`/`SITE POLE ASSEMBLIES`/...
Add subassemblies for stub-outs, pole, base, and grounding as appropriate.
### Festoon Lighting
> [!info] Also Known As
> * string lighting
> * market lighting
> * catenary lighting
> [!info] Takeoff
> 1. `FIXTURE LABOR`/`FIXTURE LABOR 2HR`
>
> 2. `FESTOON & ROOF ASSEMBLIES`/`FESTOON CABLE HANGER & EYE BOLTS - LENGTH`
> * **Length per Unit** = Light string length
>
> 3. `COURTYARDS & LANDSCAPE`/`ALUM BOX W/ FLEX FIX, 3/4" CONDUIT - PVC40 - ...`
> * **Length per Unit** = Distance to panel + 15ft
### Other Fixture Types
| Fixture Type | Path (`FIXTURE ACCESSORIES`/`COURTYARDS & LANDSCAPE`/...) |
| ------------------------------------ | ------------------------------------------------------------------ |
| Step Light | .../`STEP FIX, 3/4" CONDUIT - PVC40 - ...` |
| Bollard | .../`BOLLARD, 3/4" CONDUIT - PVC40 - ...`[^2] |
| Up-light | .../`PERMA POST, 3/4" CONDUIT - PVC40 - ...` |
| In-grade up-light | .../`3/4" CONDUIT - PVC40, IMC Elbow, ...` |
| Fixtures built into cabanas/pergolas | .../`ALUM BOX W/ FLEX FIX, 3/4" CONDUIT - PVC40 - ...` |
| Handrail light | .../`ALUM BOX W/ FLEX FIX, 3/4" CONDUIT - PVC40, IMC ELBOW - ...` |
[^2]: If we don't own concrete, delete pre-cast bollard base from assembly
## FAA Lighting
