Now wait a minute read the OT.
Note the words:
“speculative retail plaza building” and “Specifically in this case I am sizing a service for a 15,000 square foot single story strip plaza type building”
”I am talking about an empty shell. No tenants yet. All we need is the service. These are built all the time.”
Nobody said anything about restaurants or tanning solons, and if you go in guns a blazing “speculate’n” about 25-30va a foot calculations, then you can watch your client shop your number for a better speculation. Start off with 15va for retail space then when they bring a restaurant in work up a price for it, anyone who has ever developed retail space knows that some tenants have bigger electrical needs and they know they aren’t free, and how to make those tenants pay for them.
To answer the question someone here asked the last tanning salon in a retails space I built had a 400A 120/208V 3Ø service.
