Aerial Lift

For my hw, I am doing take off for a 1 story 28325 sq ft building.
I have to account for the costs for the total job expense. The problem is I don’t have experience in the industry.

Can you give some average total cost for electrical distribution, branch, and lighting job.

If I also account for permit cost of 1 %, would I be multipling to the total labor and material cost, subtotal all costs, or profit???
I am taking a class for the major but I don’t have the construction back ground.
