### 2. Takeoff
|
|
|
|
1. Build Items in Distribution:
|
|
* Panelboards
|
|
* Switchboards
|
|
* Meter centers
|
|
* Generators
|
|
* Transfer switches
|
|

|
|
|
|
2. Takeoff Common Assemblies:
|

|
|
|
|
3. Takeoff Items in Item Database:

When building panelboards/switchboards,
|
|
add terminations according to an example from the schedules.
|
|
**Do not include feeder terminations.**
|
|
|
|

|
|
|
|
#### SPD's/TVSS's
|
|
|
|
Labor only.
|
|
|
|
Specific item is not important, but I use
|
|
`SPLITTERS / SOCKETS / CABINETS`/`METER SOCKETS & CABINETS`/`METERING CURRENT TRANSFORMER`
|
|
(Labor = 1.5hrs)
|
|
for consistency.
|
|
|
|
#### Submeters/Power Monitors
|
|
|
|
See [[switchgear#SPD's/TVSS's]]
|
|
|
|
#### Panelboards
|
|
|
|
`DISTRIBUTION`/`DIST PANELS & UNIT LOAD CENTERS`/...
|
|
|
|
#### Enclosed Circuit Breakers
|
|
|
|
Treat as disconnect switch.
|
|
|
|
#### Generators
|
|
|
|
Add `DISTRIBUTION FITTINGS`/`GENERATOR SET UP`.
|
|
|
|
#### Generator Connection Cabinets
|
|
|
|
Use a Distribution Panel of equal amps.
|
|
Or a transfer switch.
|
|
|
|
#### Transfer Switches
|
|
|
|
> "300A ATS"
|
|
|
|
##### Transfer Switches 1200A+
|
|
|
|
Use 1200A and add an additional `TRANSFER SWITCH` item
|
|
to make up the remaining amps.
|
|
|
|
#### Meter Centers
|
|
|
|
`SWITCHGEAR & METER CENTERS`/`METER CENTERS`/`... METERING SECTION`
|
|
|
|
Adjust Factor 1 for meter stacks, delete zeroed items.
|
|
|
|
### 3. Review
|
|
|
|
1. Generator
|
|
* Ensure takeoff is in the generator Area and System breakdowns
|
|
* Put location, quantity, and type on OneNote
