Estimating Total Cost of Bridge Construction using ABC and Conventional Methods of Construction

项目名称：	Estimating Total Cost of Bridge Construction using ABC and Conventional Methods of Construction
摘要：	According to the U.S. Department of Transportation (USDOT) status report of 2013, 25.9% of the total bridges in the United States are either considered structurally deficient or functionally obsolete. There is therefore a pressing need for significant bridge repair and replacement efforts (DOT 2013). These bridge projects create a challenge to State Transportation Agencies (STAs) across the country in order to minimize the associated traffic disruptions in a safe way, while preserving the quality of the work and fulfilling budget constraints. In an effort to combat this challenge, the Federal Highway Administration (FHWA) is adopting and promoting the implementation of accelerated bridge construction techniques (ABC) through the “Every Day Counts” initiative to expedite project delivery and minimize their impacts on the transportation network (FHWA 2012). Accordingly, a number of STAs are implementing ABC techniques and experienced positive outcomes in a significant number of bridge replacement and/or rehabilitation projects. However, ABC techniques are often associated with high initial costs, which deters many STAs from a wider implementation of these techniques (Transportation Research Board (TRB) 2013). In addition, the impact of adopting these accelerated techniques to current bridge design and construction processes is not fully understood, which adds to the complexity of choosing ABC over conventional methods in bridge projects. Therefore, there is a pressing need to provide decision makers with a comprehensive tool for estimating the total cost of ABC projects including: construction, indirect, agency cost, and user costs. This tool will facilitate comparing the total cost of bridge repair and replacement work under both ABC and conventional methods.
