Transportation Research Record, 1984•trid.trb.orgAs one of several steps to address the massive and worsening bridge problem, the
Pennsylvania Department of Transportation decided to develop ready-to-use, low-cost
bridge design standards for small bridges. Buchart-Horn, Inc., retained by the department,
developed the standardized bridge plans for 18-35 ft, 30-90 ft, and 90-130 ft span ranges,

As one of several steps to address the massive and worsening bridge problem, the Pennsylvania Department of Transportation decided to develop ready-to-use, low-cost bridge design standards for small bridges. Buchart-Horn, Inc., retained by the department, developed the standardized bridge plans for 18-35 ft, 30-90 ft, and 90-130 ft span ranges, using steel, concrete, and prestressed concrete materials. The standards for timber and buried structures will be published soon. Three types of superstructures and two or three types of substructures, including pile-supported footings for each series, have been incorporated. Each set of standards includes and illustrates step-by-step procedures for developing a set of bridge plans from the standards. The data assembly (computations) sheets and blank plan sheets for a bridge with spaces provided for dimension insertion are included. The user completes them based on field information, geometry, and soil conditions. The completed sheets become construction plans. The contractor, when preparing bids, has the option of building the structures specified in the contract or developing an alternate structure from the standards based on the predefined parameters in the contract. The plans are approved for federally funded projects. The ultimate goal is to expedite and economize bridge replacement efforts while minimizing inconvenience to the public. Although this is not an ultimate answer, it is a step in a positive direction. The productivity realized using these standards will be enhanced when they are incorporated in the Computer Aided Design and Drafting system.
