This structural detail and schedule establishes minimum edge distances, bolt spacings, embedment depths, and concrete thicknesses for embedded bolts ranging from one-half inch to one inch in diameter. The concrete has a minimum compressive strength of two thousand five hundred pounds per square inch and receives attachments with thicknesses per drawings. Embedded bolts are specified as American Society for Testing and Materials A307 or F1554 Grade 36 minimum. These minimum edge distances and bolt spacings apply when locating embedded bolts not specifically detailed elsewhere on the plans. Locations for these details require structural engineer approval unless specifically noted otherwise on plan.
