Site Class C vs. D
Site Class C vs. D
(OP)
Does anyone know if there is historical data or information that compares the building costs of building an office tower (approx. 250 feet, 25 stories) on a seismic Site Class C vs. a Site Class D. I am trying to work up a quick number to compare the two. The overall building size and construction has yet to be determined. I was hoping for a rough idea, percentage based or unit price savings etc.. Thanks for any input.






RE: Site Class C vs. D
that being said, most geotech reports will not reclassify a project to a lesser site class unless you specifically ask them to. I don't think they mind, but most buildings are designed before the soil tests are completed (and as such are designed for site class"D")so changing to a more favorable site class does not generally do anything. and leaving it will be conservative.
Sorry it's not a cookbook answer.

Obviously you're not going to have masonry shear walls on a 25 story building, but I think the example clarifies what I'm saying.
