### Poke-Thru's
|
||||
|
||||
1. Read about the project specifications and construction type
|
||||
2. Locate Equipment Schedules
|
||||
|
||||
### 2. Takeoff
|
||||
|
||||
1. Takeoff all equipment that is not #12
|
||||
2. Go by Drawing in chronological order
|
||||
3. Takeoff Enlarged Drawings
|
||||
4. Do final checklist in electrical takeoff notes

> It is sometimes easier to rebuild a designation than to modify it.
|
||||
> For designations with existing takeoffs, Right-Click > `Empty Designation`.
|
||||
> The build process can then be completed anew.
