Here's a really interesting piece of irony! I was just talking to one of the owners of the firm i work for, and we were talking about granite. He went off on talking about when he was fresh out of school working on a building re-cladding of a building in Chicago! I said NO WAY. Yes, it was the Standard Oil Bldg. Here's some interesting info about that little project. When the building was built, nobody really understood the long term affects of a 1/2" sliver of marble exposed to direct sunlight. The marble warped and poped loose of it's clips causing 600lb pieces of marble to come crashing into the park below. They apparently handed out hard hats to walk into and out of the building.blacksmith37;608378; said:I missed your interlocking corners; although I like the holes in the pad for the vertical rebar the best ( and the masic internal coating). Looks Good !
Overengineering might be stainless rebar so you could switch to salt water at some time.
Nothing personal , but as an engineer, I have never been impressed by the mechanical abilities of architects. One super architect screw-up I was familiar with was the replacement of the marble skin of the Standard Oil Bldg in Chicago . It cost more than the original building.
I wouldn't mention using A36 steel as it is the lowest common denominator for structural and plate; It would be difficult to find a piece of mild steel that did not meet the requirements of A36.
The firm he worked for had to design a completely new system to attach the new 2" thck granite sheets to the steel which was designed to carry a 1/2" piece of marble. A 2 story mach up was built in lower indiana with the new clip system before the quarry mined the new granite. The cost was around 80 million dollars which was about half of the cost of the original structure. Re-cladding the building was the only solution, and the procedure was a lot more involved than just clipping on new panels.
