Abstract:

Reid Crowther and a group of Western Canadian cities have collaborated in the development of a Bridge Management System (BMS) software application appropriate for municipal size inventories. Database functions are separated into Static (inventory) and Dynamic (visual inspection) modules that are suitable for bridge and culvert structures. The database modules are structured to include both essential and non-essential categories. A numerical 9 point visual condition rating system is used for inspection data. Data records can be maintained for both representative and worst condition of each inspected element. Analysis routines are provided that i) compute structure rating values, ii) establish network wide management strategy options and iii) facilitate detailed site based present value computations. The Structure Ratings routines compute ratings for each structure site in each of nine Basic Rating categories from which an overall site "Sufficiency Rating" is computed. Present value based network analysis routines facilitate the prediction of a least cost long-term management strategy for each structure in the inventory. The least cost strategy prediction is based on an evaluation of estimated whole life costs associated with managing inventory structures by one of five so-called fundamental strategies. A "What If" analysis feature is provided as a means to address various simplifying factors incorporated into the network analysis. The detailed site analysis routines facilitate detailed life cycle cost analysis of management options for User selected sites.
