# Electrical Takeoff

> [!important]
> Complete [[pre-takeoff-research]],
> including [[conest-wiring-method-selection]] and [[conest-wiring-device-research]],
> before beginning takeoff.

> [!tip]
> Use [[heating-designations]] for uncertain scope.

## Garage

In conventional slab garages,
use ENT and PVC as permitted.

In precast slab garages, use EMT.

## Receptacles

> [!important]
> Receptacle symbols are not standard.
> Always check the electrical legend.

## 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

> [!info] Breakdowns
> * `Area` = "XX - Level XX Building"
> * `Phase` = "Building - Back of House (BOH)"

Takeoff homeruns in Building breakdowns,
even where serving Amenity spaces.

## Mechanical Connections

### General

`COMMON ASSEMBLIES`/`MECHANICAL CONNECTIONS ...`/...

When using length-based assemblies use adders per [[feeders-takeoff]].

%% TODO
#### PVC Connection Assemblies

#### Flex

[[conest-wiring-method-selection#Liquidtight Flex]]

%%

### Stair Pressurization Fans

Assume branch circuit conductors must be protected
per [[fire-resistive-wiring-methods-takeoff]].

### Roof Mounted Equipment

#### Unit Condensing Units

##### Homeruns

> [!info] Breakdowns
> * `Area` = _Match unit_

.../`CONDENSOR HOME RUNS`

* **Horizontal:** Distance from load center to FCU.
    (~50ft expected)[^1]

* **Vertical:** floor-to-floor distance from FCU to CU

[^1]: [[2026-05-04_14-57-49#Unit Condensing Units]]

| Level    | Horizontal | Vertical | Length |
| :------- | ---------: | -------: | -----: |
| Level 01 |        150 |       40 |    190 |
| Level 02 |        150 |       30 |    180 |
| Level 03 |        150 |       20 |    170 |
| Level 04 |        150 |       10 |    160 |

##### Connections

> [!info] Breakdowns

.../`CU CONDENSER SLEEVE W/ FLEX - NO HMRN WIRE`

`NO SLEEVE`:
Routed through a "doghouse"
(a large weatherproof opening)
with several other feeds.
Used where drilling openings for individual sleeves
would be impractical.

`PVC SLEEVE`, `EMT SLEEVE`:
Routed up through the roof,
(optionally through a disconnect)
with flex to the equipment.

#### Equipment Racks

Max 20 disconnects per rack

`DISTRIBUTION`/`TRAPEZE RACK SUPPORT ...`/...

## Trash Chute

1. **Horizontal:**

    `COMMON ASSEMBLIES`/`MECHANICAL CONNECTIONS ...`/...
    * **Length** = Length per drawings, 100ft if not shown.

2. **Vertical (Riser):**

    * `Area` = "Typical - Building All Levels"

    Takeoff: `COMMON ASSEMBLIES`/`MISC ASSEMBLIES`/`TRASH CHUTE RISER CIRCUIT...`
    * **Length** = average floor to floor height

## Fire/Smoke Dampers

[[fire-alarm-takeoff#Fire/Smoke Dampers (FSD's)]]

## 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|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.
