• Deck Thickness
• Corridor Ceiling type

2. In the drawings, locate:

• Unit Panel Schedules
• Unit Load Calculations
• Riser Diagram
• Subfeed schedule (if present)

2. Takeoff

1. Determine wiring method

   Construction Type	Wiring Method	Subfeed Options
   1,2	MC Cable	MC, PVC, EMT
   3,4,5	NM Cable	SER, EMT

   %% TODO: Create flow chart for wiring methods. Some cases to mention:

   • Renovations (may not be able to run in slab) %%

2. Route subfeeds to the Meter Centers using appropriate adder lengths

   Tip

   Identify if and where typicals can be used

3. Assign material to lengths and apply Voltage drop if applicable

4. Pigtails and Wireway Troughs if applicable

3. Extension (Review and Checking)

1. Use the extension tab to determine the Correct Quantity
