In the summer of 1993, the Bridge Management Task Force chairman requested that the Virginia Transportation Research Council begin a study of the maintenance, repair, and rehabilitation unit costs needed for the operation of the Pontis system. Because Pontis provides networklevel analysis, implementing it requires a fundamental change in the business procedures of the Virginia Department of Transportation. The establishment of network-level cost data is one step in the implementation of Pontis. The shift from a bridge-specific focus makes existing data unsuitable, and alternatives need to be explored. Since other states face similar problems, the Federal Highway Administration, the American Association of State Highway and Transportation Officials, and the National Cooperative Highway Research Program have initiated studies of these maintenance, repair, and rehabilitation costs. Rather than initiate a study of its own, the Virginia Transportation Research Council chose to follow these studies closely, and to make suggestions for implementing the findings from these studies within the Virginia Department of Transportation. This report provides the Task Force with a set of recommendations for implementing AASHTOWare TM Pontis TM Release 3.0.
