Guy that owns the Urban Active is a friend of mine. He has a architect, interior designer, and his wife that make their request to me, I take structural steel prints of the building to a structural engineer and he makes the stair and rail design structurally sound and completes a set of shop drawings which lays out each piece in the project ($1500. - $3000). They will always oversize material something ridiculous and architects don't care about maximizing your material. I takes 7 copies, 1 Me, 2 Owner, 3, General Contractor, 4, Local Building Inspector, 5 Local Fire Dept Inspector, 6 Owners Liability Carrier, 7 Architect and I wait for 2,4,5,7, to approve. All the people above are looking for is to put the liability off on someone policy or spread it around as much as possible. As far as price have done it enough I can quote by feet of rail and number of stair tread. Figure steel cost and time to fabricate and install. Sometimes it actually takes longer to get the paper work done than to do the job. There are 4 of the Urban Actives (old Golds) in Nashville. They are looking at the new stainless cables under tension system for a few gyms but you always have to satisfy the 4" ball rule where a 4" sphere can not pass through the rail.
