Basic Foundation Replacement Cost
I am a student at Cal Poly SLO and i'm trying to estimate the cost of building a 'simulation warehouse' next to another existing building. It's basically just a small building with big doors and storage racks on the inside. It will also most likely have power/internet so they can connect to the campus servers inside the building but that doesn't really have anything to do with the foundation, or does it?
The area is 25ft x 22ft in San Luis Obispo, California. There will be no plumbing. Keep in mind my professors main goal is to make it as cheap as possible (any suggestions on building wall material would be helpful too).
My main question is concerning the foundation. Where my prof wants to build it there is already a concrete foundation (maybe 6-8 inches thick) but it is in pretty bad shape since it is exposed. It has a couple pretty big cracks in it and looks a bit uneven.
So the question: Do i need to replace this concrete and put in a real foundation?
And, if anyone could give me a rough estimate that would be great.

guess calpoly's not high on the language arts :no: to start, you might suggest your webmaster ask for the proper english
why cheap ? foundation's are usually measured in width - yours sounds like a slab - doesn't cal poly have an engineering dept ? :huh:
Buiding with big doors(wide, high or both?) and racks indicates there may be forklifts or possible concentrated loads on a cracked 6" to 8" slab. - Not a good situation/combination and it would be prudent to put in a new, proper slab rather than take a chance on trying to replace it after the new building is built on top of it.
If you try to use the existing slab, it will have to be certified as acceptable for the loads by an engineers before anyone can get a permit to build the the new "garage" on top of it..
You have to address the low inial cost with the long term replacement/repair costs.
It is sure a simplistic, unrealistic problem unless the prof wants to use it as a garage for his car. Just a text book problem without regard to the real world.
The path to knowledge is more rewarding when you're the one holding the flashlight.
Green Building Square Foot Costbook
by Sweets, 2011
It's in the Kennedy Library on the Cal Poly SLO campus, North Perimeter Drive, 1st floor, reference section, TH880.G744 Ref. It's checked in and available.
That took me 20 seconds to find using the Library's web site. The rest is up to you. For such a small structure, I'd add 20% to the square foot costs.
