675 When required, structural members shall be secured to the pier or bent with dowel rods. Holes for dowels shall be filled with mortar at fixed ends and with crack or joint filler at expansion ends. Longitudinal keyway joints shall be cleaned. A coat of cement mortar shall be scrubbed on the surface. The joint shall be filled with a non-shrinking grout composed of 1 part portland cement, 2 parts No. 23 fine aggregate, and an approved non-shrinking additive or a non-shrink, non-metallic cementation grout in 510 accordance with ASTM C1107. All bolts or dr ains shown on the plans as necessary or desirable to be placed in the concrete sh all be placed by the methods and at the locations shown on the plans. Necessary tie rods, tie bolts, and hardware for tying structural members together shall be furnished. Dowel holes shall not be grouted nor concrete or the forming thereof, be placed in floor slabs, diaphragms, or shear keys prior to receipt of complete documentation of the acceptability of the structural members and bearing pads, including the satisfactory laboratory reports and certifica tions in accordance with 915.04(f). Neither the structural members, nor the bearings will be considered incorporated into the work, 520 and neither will be paid for until this documentation is accomplished satisfactorily. Railing, when required, shall be of the type shown on the plans. The component parts shall be in accordance with 706, unless otherwise indicated on the plans. Other precast concrete or precast prestressed concrete structural members shall be placed in the structure in accordance wi th the plans and the specifications or special provisions indicated for the type of structure being built. Cranes or other heavy erection equipment may be operated on the precast concrete or precast prestressed concrete structural members only if approved in writing and if 530 a proposed operating procedure is submitted showing loading, dist ribution of loads, resulting stresses, and that the design of the structural members is satisfactory to handle these loads. However, such approval shall not relieve the Contractor of any damage from this operation.
