Have a series of circa 1917 empty warehouses. Here are the basics:
6-7 stories each (front of building facing street is 6 stories, rear of building facing vacated alley is 7 stories - a walkout basement condition). Brick/block bearing exterior walls, heavy timber interior construction of 8" x 12" or larger girders, 6" x 10" joists or larger, 8" x 8" posts or larger. Solid plank floor with t & g flooring on top. Building is and will stay fully sprinklered.
Developer converting buildings to mixed-use and are being put on Federal and State Historic Registry. Ground floor (street facade entry side) to be office and/or retail. Basement (walkout on alley) to be retail and/or restaurant. And remaining 5 stories above to become residential apartments.
Few separate questions:
1. How to handle the fire separations (mainly horizontal) when certain elements of the building cannot change due to historic rehab requirements?
2. What about ADA accessibility if same issue above (historic) is required?. That would be for entry/public access into the building AND for residential unit requirements on upper floors? Main floor is 4' higher than street.
3. Same issue (historic) for energy codes. Exterior walls will stay exposed brick so envelope requirements will be difficult to achieve.
I know there are a lot if different issues asked above, but didn't want to cross post(?)
Thank you.
