This is a retrofit of an existing office building within a medium manufacturing company. The office building is about 5000sq ft and the overall facility about
100 000sq ft. Since this is an existing space, storm water, sewer system, potable and electrical systems are shared with all the facility. Can I leave out of the boundary all those services, treatment plant, storm and sewer pipes and collectors, potable water pumping systems, etc. If not, I would have all the facility within the boundary, which don't make sense to me. At this moment I'm taking into account the office space and some hard-scape amenities such as sidewalks, parking lot and car entry to the property since those are used by the construction trucks. What do you think about my approach. Many thanks.
