What do you think you need? Have you ever heard about a GREASE TRAP? Do you know how much it wil cost you? What about HVAC and Toilet? Talk to your GC why you need to know about them. Grease Trap alone will cost you easily $15,000 to $25,000. HVAC on your roof top will never be enough to pass inspection unless you add addtional 5 to 10 Tons for 1,500 SF space. How about toilet? Can I go with one ?...
