## Preparation
|
||||
|
||||
### Riser
|
||||
|
||||
1. Locate MDF and IDF Rooms
|
||||
2. Service entrance conduit "Site Low Voltage Ductbank (SLVDB)"
|
||||
3. Riser throughout building
|
||||
4. Sleeving for riser
|
||||
|
||||
### Devices
|
||||
|
||||
1. Locate Proposal/Scope of Work. Determine ownership and takeoff responsibility:
|
||||
* Cabling
|
||||
* Conduit & Pathways
|
||||
* Sleeving
|
||||
2. Locate which plans the LV is taken off on
|
||||
3. Locate LV Details
|
||||
4. Read about the project specifications and construction type
|
||||
5. Fill out OneNote
|
||||
|
||||
## Takeoff
|
||||
|
||||
1. Takeoff devices as shown throughout the building
|
||||
2. Takeoff Conduit Riser as needed
|
||||

## Backbone Riser
|
||||
|
||||
> Going forward for the riser backbone. It's better to utilize a Typical and put 15' of the conduit riser on each floor bc currently it has the entire riser on the mezzanine level. So when Ops goes to release the conduit from the CBOM they are going to have it all on the mezzanine level and not on every level where it's needed
