I am trying to establish the correct constrution type for an existing building for purposes of renovation. It is about 100,000sf of one story metal building with the majority of the building used for storage of materials. None of the materials stored are explosive or even flamable. The ancillary areas include about 5,700sf of office, 900sf of truck services such as oil changing and washing, and obout 900sf of repackaging operations. The repackaging is adding water to a dry caustic powder and repackaging for sales and shipment.
The building is fully accessible (around the perimeter) and is fully sprinkled.
The building itself uses fire spray coated steel columns throughout. The steel roof beams, joists, and decking are merely painted. The exterior walls are all steel construction (except of course insulation) as well. The roof is about 23' above the floor.
Utilizing area increases allowed due to the fire supression as well as the accessibility increases I conclude it could be classified as type IA, IB, IIA, or IIIA construction. I see types IIB and IIIB as allowing 97,500sf and thus falling a bit short.
So, thus far are my conclusions correct?
As an aside, how can one tell, in existing construction, what the fire resistive rating is for steel columns with spray applied coating?
