Hi All - Happy Flex Connect Week!! I've had a new project come alive, and was tasked to figure out how to make our mezzanine design work for a mezzanine that covered 50% floor space in a Type IIb building - Car Condo Property. In the past, the only way to meet the code (sprinkler, voice comm system, and non-combustible materials) was to use concrete pan filled decking which was/is expensive. Not just an expensive deck, but also upgraded steel, concrete pad/footers, etc due to the increased weight. We had always been told that it can't be done, but we have found a work around. 3/4" structural concrete panels - it fits our design perfectly by replacing the 3/4" OSB we formerly used and does not significantly impact the capacity (albeit there is a weight difference - 180lbs/panel). How does this impact justification for mezzanines in pre-construction? 1/3 coverage may not move the ROI needle enough for small builds, but does 50%?
