Augered Cast-in-place Piers

[tdsull]

I am looking for design references for augered cast in place piers (Caissons).

The contractor wants to drill 14” piers/caissons through sand to support a 2 story structure. No geotechnical information available.

Thanks

No geotechnical information available.

I'd get some.

A good geotech will provide you with design criteria for determining the proper depth and diameter of the ACP's.

Without it you are placing yourself at risk.

Deep foundation without geotechnical data = very bad idea.

Get a geotechnical exploration and report, then proceed.

Definitely, you need a geotech!!
