Section 11: Miscellaneous Details
Anchor: #i1003663Bearing Seat Details
Bearing seats shall normally be shown on the plan view as detailed below. The centerline of bearing shall be measured perpendicular to the face of the backwall. The buildup shall follow the skew of the beam. Buildup dimensions need be shown only once in this view. A typical bearing seat detail, as shown below, shall be included on the Abutment Sheet. Note that details shown are for a standard size cap. Larger caps or unusual details may require special details.
Dowels D shall normally be placed at outside beams only, although staged construction may require additional dowels, and wide structures may require dowels to be moved to inside beams. Dowels D will be used at the ends of simple spans but shall not be used at the ends of multiple span units. Refer to the Bridge Design Manual for additional information.

The general notes, title block, and engineer’s seal shall normally be shown on the detail sheet in the format given below. Note that there will be considerable variation in the general notes between jobs, depending on structural needs. Particular care shall be taken to ensure that the loading criteria given are correct. If armor joint is used at the abutment, add to the general notes:
