# 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
> ...
> ```

| 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

| ------------- | ------------------------------ |
| NM Cable      | `NM ASSEMBLIES`/`HI HAT - ...` |
| 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                         |

| MC Cable      | `MC ASSEMBLIES`/`UNDER CABINET - ...` |

> [!note]
> Takeoff 2 fixtures if jumping over oven

## Paddle Fans

## 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

> * 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`/...)          |
