Hi ssadagopan,

So sorry for the long delay in answering your question! The bottom of the beams on the low side are 9'-1" above the concrete slab floor, and the bottom of the ceiling car-decking is at 10'-1". At the high end the bottom of beams are at 14 ft. and the car-decking is at 15 ft. Hope you still get some use from this info!
