In precast slab garages, use EMT. ## Receptacles ## Floor Boxes `COMMON ASSEMBLIES`/`FLOOR BOXES`/... ### Poke-Thru's Use suitable floor box assembly, delete floor box items, add `ITEM DATABASE`/`WIRING & SYSTEM DEVICES`/`FLOOR BOXES & FITTTINGS`/`GENERIC - FLOOR BOXES & ACCESS`/`POKE-THRU W/ DUPLEX RECEPTACLE` ## Homeruns ### Lighting Homeruns * `Area` = "XX - Level XX Building" * `Phase` = "Building - Back of House (BOH)" Takeoff homeruns in Building breakdowns, even where serving Amenity spaces. ## Clubline Raceway [Raceway Systems - CRG](https://crg.us.com/products/raceway-systems/) Clubline Raceway, also called CRG Raceway, is a glorified cable management trough. It is not a [[nfpa-70_376_metal-wireways|wireway]], so conductors must be run in a [[nfpa-70_national-electric-code#Chapter 3 Wiring Methods and Materials|Chapter 3]] wiring method. Count receptacles normally, using ==surface-mount EMT assemblies==. Create a temporary item for the raceway itself. ## Mechanical Connections `COMMON ASSEMBLIES`/`MECHANICAL CONNECTIONS ...`/... When using length-based assemblies use adders per [[feeders-takeoff]]. ### Stair Pressurization Fans Assume branch circuit conductors must be protected per [[fire-resistive-wiring-methods-takeoff]]. ### Roof Mounted Equipment #### Unit Condensing Units | Level | Horizontal | Vertical | Length | Count | |:-------- | ----------:| --------:| ------:| -----:| | Level 01 | 150 | 40 | 190 | | | Level 02 | 150 | 30 | 180 | | | Level 03 | 150 | 20 | 170 | | | Level 04 | 150 | 10 | 160 | | Put homeruns on the `Area` of the dwelling unit.
