Benefit-Cost Analysis of CDOT Fixed Automated Spray Technology (FAST) System
Started: November, 2012 Ended: November, 2014 Project ID #4W4301 Status: Completed
The objective of this research was to determine the cost-effectiveness of all the existing Fixed Automated Spray Technology (FAST) Systems operated by the Colorado Department of Transportation (CDOT). The project developed a best management and performance practices guide for the future planning, design, construction, operation and maintenance of FAST systems for Colorado’s highway and bridge networks.
Fixed Automated Spray Technology (FAST) systems aim to deliver anti-icing chemicals to key locations in a controlled manner, using pumps, piping, valves and nozzles or discs. . In North America, FAST is a relatively new technology that has gained popularity since the late 1990s. The Colorado Department of Transportation installed its first FAST unit in 1998, and now there are 32 FAST units installed on bridges across the state. Currently, some CDOT regional maintenance personnel have concerns regarding the performance, cost-effectiveness, and safety benefits of the technology; whereas others have a favorable view toward FAST based on historical performance and observed benefits. In this context, CDOT would like to determine the cost-effectiveness of all the existing FAST units. In examining the performance of existing systems, the project will also develop a best management and performance practices guide for the future planning, design, construction, operation and maintenance of FAST systems for Colorado’s highway and bridge networks. The study will provide CDOT with improved information and a procedure for analyzing where improvements can be made to maximize the return on FAST investment, whether existing systems are financially beneficial and, if they are, how and where they can be used in the future to produce similar benefits to both the agency and to public.
