# Fixture Designations

## Naming

### Format

```regex
<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 (MC) LV 20ft
> HU - Surface - 1.5hrs (MC) LV 20ft
> HU - Surface: Pendant - 2.0hrs (MC) LV 20ft
> HU - Surface: J-Box For Future Fixture (MC) LV 20ft
> HU - Recessed (MC) LV 20ft
> *** Condo Units ***
> CU - Surface: Tape - 1.0hrs (MC) LV 25ft
> CU - Surface: Wall (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`

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`

## Surface Mount

> [!info] Surface Mount Fixtures
> * Wall Mount (Sconce)
> * 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.

Separate these fixtures by labor, not length

```
A - Surface: Tape - 0.5hr (01-06ft) - MC #12 40ft
A - Surface: Tape - 1.0hr (07-12ft) - MC #12 40ft
A - Surface: Tape - 1.5hr (13-18ft) - MC #12 40ft
A - Surface: Tape - 2.0hr (19-24ft) - MC #12 40ft
A - Surface: Tape - 2.5hr (25-30ft) - MC #12 40ft
A - Surface: Tape - 3.0hr (31-36ft) - MC #12 40ft
A - Surface: Tape - 3.5hr (37-42ft) - MC #12 40ft
A - Surface: Tape - 4.0hr (43-48ft) - MC #12 40ft
A - Surface: Tape - 4.5hr (49-54ft) - MC #12 40ft
```

## Recessed

> [!info] Recessed Fixtures
> * recessed downlight
> * recessed linear
> * wall grazer
> * troffer

| Wiring Method | Assembly Path                  |
| ------------- | ------------------------------ |
| 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                         |
| ------------- | ------------------------------------- |
| NM Cable      | `NM ASSEMBLIES`/`UNDER CABINET - ...` |
| 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 (hrs)                         |
| ------------ | ----------------------------------- |
| Non-Linear   | 2                                   |

> 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

> 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 - ...`
