Development of Draft Construction Safety Standards for Excavations

This report contains the input document to the workshops (the working draft), summaries of the workshop comments, and an analysis of the suggestions and commentary produced by the workshops.

The purpose of this study is to determine which unshored configurations of compound slopes would possess stabilities equal and equivalent to the stability of either a 5 foot high vertical or a 12 foot high 3/4 to 1 unshored slpoe, as allowed in the CAL-OSHA Construction Safety Orders.
