This paper describes the Alberta Bridge Management System (ABMS) with emphasis on the Long Range Planning (LRP) System. LRP is designed to provide a network or system level view of future bridge maintenance, repair and replacement activities. LRP utilizes existing inventory and condition databases in conjunction with deterioration models and economic analysis to provide this information. The LRP system includes level of service criteria and can work with both constrained and unconstrained budget funding. LRP is designed to help manage Alberta's bridge infrastructure network. The need for comprehensive bridge management is especially important in this age of budget reductions and limited resources. The LRP system has been designed in a modular fashion to facilitate changes and additions to the system over time. Each module was developed by current users and decision makers to ensure a technically sound analysis and to lend credibility to the LRP System. A description of the economic analysis methods and the maintenance and replacement algorithms used in LRP is presented in this paper. Currently LRP is being programmed and tested. Phase I is scheduled for completion in the Summer of 1994, and Phase 2 should be complete by the end of 1994. (A)
