Abstract: Development of a new generation of Bridge Management System (BMS) capabilities has been a high priority for CALTRANS for the past four years. Although the Department has had a bridge inventory system, with a very extensive suite of management reports, since the late 1970s, CALTRANS has recognized that selected newly-available technologies could be integrated into its management decision-making, planning, and operations to substantially enhance its effectiveness in managing a 24,000-bridge inventory. One of the key components of CALTRANS' BMS is Pontis, a network-level optimization system which analyzes bridge deterioration, costs, and functional needs to plot a long-term bridge management strategy, and recommend a short-term program of projects consistent with that strategy and funding availability. To complement the network level analysis provided by Pontis, CALTRANS is implementing a computerized image storage and retrieval system named BWS to aid an engineer in project level analysis by providing quick and easy access to bridge inspection records and as-built construction plans.
