Essential Facility - Acceptable Settlement of Structure
Essential Facility - Acceptable Settlement of Structure
(OP)
I'm in the beginning stages of designing a State Police Station. 60' x 120', one-story rectangle. We just completed the Geo-Tech study and the results were that the area is susceptible to liquefaction with a total anticipated settlement of 4". The 4" is if we just do a typical slab on grade foundation. We could do a waffle style slab a reduce the total differential settlement of the building, however, the overall settlement would be the 4". The other option is to do piles and get down to the good soil (piles would be about 30-35ft in length).
My question, what is an acceptable amount of overall settlement of soil? I'm really concerned about differential and total in this situation. They will have weapons, ammo, narcotics, money, files, etc. that are all sensitive material. In the event there is a major crisis and they need the weapons and ammo, if this building settles and the doors are jammed shut then this building is essentially useless (no pun intended!). Is there a code requirement for settlement? I'm surprised the Geo-Tech doesn't know.
Thanks.
