Floor Framing Systems on Concrete Drilled Piers
Floor Framing Systems on Concrete Drilled Piers
(OP)
Hello:
Am designing a 5000 sf home in NW Dallas metroplex. Soil turned out to be expansive from soil report. Geotech recommended raised concrete slab on piers. Am new to drilled piers but upon looking at some projects that I have seen in the past I was wondering why it has to be a raised concrete slab. Floor plan is not a rectangle and am sure a cip slab and beams is going to be very pricey. I dont see a valid reason why a steel frame with metal deck and concrete topping can not be a floor framing system. Your input will be appreciated.

1) Other possible requirements such as durability, fire protection etc that might affect costs.
2) The steel system will probably be a good deal deeper than the concrete. The skirt or whatever may cost real money.
3) I doubt that the concrete is all that expensive if done properly. It's still rough work, kinda like SOG. They seem to do a lot of this in Australia so it must make some sense.
4) I thought that the stock answer to this in TX was the post-tensioned SOG: Link
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
