See <br />Drawings for scheduled lap splices. <br />E.At Expansion Joints: <br />1.Reinforcing bars and wire fabric shall NOT be continuous through <br />expansion joints, unless otherwise indicated on Drawings. <br />F.Splicing: <br />1.Unless otherwise indicated on Drawings provide lap splices for bar sizes <br />#11 (ø36) and smaller by lapping ends, placing bars in contact, and tying <br />tightly with wire in accordance with requirements of ACI 318 for lap <br />lengths indicated on Drawings. <br />2.At all #14 (ø43) and #18 (ø57) bars and where mechanical splices are <br />specifically indicated on Drawings, comply with requirements specified in <br />this Specification section under “Mechanical Splicing Systems”. <br />3.Do not splice reinforcement except as indicated on structural Drawings. <br />4.Tension couplers may be used and installed per manufacturer’s <br />specifications where indicated on Drawings or as approved by Engineer.
