Where limits are not shown, piping shall be removed to a <br /> point that is at least 5 feet outside of the limits of new construction. Piping not <br /> indicated to be removed, or which does not interfere with the new construction, <br /> shall be removed to the nearest solid support, capped, and left in place. <br /> B. Normally, piping shall be removed to the first joint outside of the limits required. <br /> Where sections of pipe exceed 16' in length the piping may be cut using saws, <br /> cutting torches, or other approved methods to provide clean, unbroken, end points. <br /> C Abandoned underground piping may not be left in place unless otherwise <br /> approved by the Engineer. Where underground piping is to be removed, plug the <br /> remaining piping that is to be abandoned.
