THE SHORING ILLUSTRATED IN THIS DRAWING IS ONLY ONE OF MANY POSS13LE SHORING SYSTEMS, TO BE DETERMINED AND USED AT THE DISCRETION OF THE CONTRACTOR AND HENDERSON SAFETY. 3. VERTICAL SUPPORT OF CONCRETE PIPE, IN PLACE WHILE PERSONNEL ARE WORKING UNDER THE PIPE FOR EXTENDED PERIODS, IS TO OCCUR ONLY FROM CONCRETE PADS PLACED ON NATIVE SOTS. 3.1. THESE SHORING FOOTINGS MAY BE 12' MIN. THICKNESS, 3' -0' x 3' -0' CONCRETE, REINFORCED w/ 15 AT W O.C. LW.
