--- tags: - occupational/takeoff - status/draft - type/guide title: Fixture Designations --- # 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 - (: )?( \(\))?( = )? ft ``` ### Phase Abbreviation (``) ### Assembly (``) [[luminaire-types]] * "Surface" - Assembly includes a junction box * "Recessed" - Assembly does not include a junction box ### Assembly Subtype (``) ### 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 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 (``) #### 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 (``) | 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: | Case | Subassembly 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 | Subassembly 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.
