In this FHWA-sponsored pool funded study, a set of decision making tools, based on the Analytic Hierarchy Process (AHP) was developed. This tool set is prepared for transportation specialists and decision-makers to determine if ABC is more effective than traditional construction for a given bridge replacement or rehabilitation project. The tool set is user-friendly, flexible to accommodate a range of construction situations, transparent as to the method of calculation, and customizable to maintain future relevance. To accommodate this task, a comprehensive literature review on a number of relevant domains such as ABC construction techniques and decision making approaches, were completed. The findings were summarized into a decision model hierarchy that was also incorporated into the decision making software. The software was tested through evaluating a set of real-world construction projects.

The traveling public has no patience for prolonged, high cost construction projects. This puts highway construction contractors under intense pressure to minimize traffic disruptions and construction cost. Actively promoted by the Federal Highway Administration, there are hundreds of accelerated bridge construction (ABC) construction programs in the United States, Europe and Japan. Accelerated Bridge Construction: Best Practices and Techniques provides a wide range of construction techniques, processes and technologies designed to maximize bridge construction or reconstruction operations while minimizing project delays and community disruption. Describes design methods for accelerated bridge substructure construction; reducing foundation construction time and methods by using pile bents Explains applications to steel bridges, temporary bridges in place of detours using quick erection and demolition Covers design-build systems' boon to ABC; development of software; use of fiber reinforced polymer (FRP) Includes applications to glulam and sawn lumber bridges, precast concrete bridges, precast joints details; use of lightweight aggregate concrete, aluminum and high-performance steel

Accelerated Bridge Construction (ABC) methods that were recently introduced in the U.S. to reduce the on-site construction duration furnish several benefits to the public and highway agencies. Further, the traffic growth in addition to increasing number of functionally obsolete and structurally deficient bridges necessitates the increased implementation of ABC methods. In recent years, several Departments of Transportation (DOTs) in the U.S. have developed decision-making models to compare broadly ABC to conventional bridge construction for a particular site. However, with increased implementation and advancements in ABC methods, there is a need for specifying a particular ABC method and a superstructure system for a site by means of evaluating the associated uncertainty. The uncertainty arises because of the activities associated with ABC methods, and constructibility and durability of superstructure systems with respect to site-specific conditions. Moreover, the interactions among the internal stakeholders such as the DOT, Designer, Contractors, Consultants, etc., while delivering a project using an ABC method contribute to the uncertainty. Understanding the need, a decision-making model is required that enables the evaluation of ABC methods and the associated superstructure systems in order to achieve optimal constructibility and durability of a bridge. The agent-based complex systems approach enables modeling and simulating the activities and stakeholder interactions in order to evaluate the impact of the uncertainty on the ABC project performance. The uncertainty can be quantified by identifying the parameters that contribute to uncertainty, and establishing parameter correlations with the site-specific data. The following outline the specific tasks performed during the research: (1) Documenting potential superstructure systems that can be used with the ABC methods for a particular region, (2) Documenting major activities and internal stakeholders of ABC methods, (3) Documenting parameters that contribute to uncertainty of the activities, (4) Developing the parameter correlations with site-specific data for a particular region, (5) Formulating the decision-making framework and demonstrating the framework using an example, and (6) Developing recommendations for future research to extend the framework to an automated decision-making model/tool.

By employing prefabricated bridge elements and systems, Accelerated Bridge Construction reduces on-site construction time and traffic disruptions, and enhances long-term performance. ABC is particularly advantageous for short-span bridges that are well-suited to standardized prefabrication. In such cases, the entire superstructure and substructure can often be constructed using prefabricated deck elements, modular decks, or systems that span the full bridge width. The construction methods can range from traditional crane installations to Self-Propelled Modular Transport units or slide-in techniques for moving the entire superstructures. This book introduces the concept of ABC and examines its application in the context of short-span bridge construction. It categorizes and details short-span bridges based on various criteria and evaluates the performance of the existing bridges. Decision-making processes regarding the adoption of ABC, choice of elements, systems, and construction methods are also discussed. Additionally, the book covers the inspection of short-span bridges and includes a design example.

Decision making is a cognitive process which includes attention, remembering, understanding, and solving. In every industry decisions are required at every step along the way. Available information should be analyzed or if information is not available it should be gathered first to come up with a decision. A predefined decision-making process helps in making informed decisions along with maintaining consistency in the decision made. Contiguous parameters to a specific application are required along with an ideal mathematical model for informed decision-making. A potential management which requires an optimal decision-making is bridge construction industry due to the fact that, the bridges not only connect communities making commute shorter and faster but also shape our lives through urban development. The need for bridge rehabilitation/replacement engenders bottlenecks and closures on existing freeways which creates outrageous conditions for travelling public. Thus, the demand of travelling public for deploying bridge rehabilitation/ replacement process using innovative construction processes evolved in Accelerated Bridge Construction (ABC). Various state departments of transportation have developed decision-making models to identify if ABC is a viable option for a site, yet the deficiencies pertaining in those models require contemplation. The herein study identifies the bridge construction contiguous parameters and models to precisely address the deficiencies in the existing decision-making models for bridges. The outcome of this study is an informed decision-making model that can be customized using site specific data in selecting an optimal bridge construction process. A decision-making tool is developed for implementation of the decision-making model. The tool os demonstrated through a case study of Parkview Bridge over US 131 in Kalamazoo, MI.

Traffic disruption due to bridge construction has been reduced to several hours with the development of methods characterized as Accelerated Bridge Construction (ABC). Associated risks and additional activities involved with the accelerated construction result in an increased initial project cost. This additional cost is offset by the benefits of reduced mobility impact time such as maintenance of traffic cost, life-cycle cost, and economic impact on surrounding communities and businesses as well as the ability to address seasonal limitations. Traditionally, the savings in user cost from reduced mobility impact time is used to justify the additional cost of accelerated construction implementations. This thesis presents a comprehensive cost model for bridge construction that incorporates economic impact on surrounding communities and businesses. Economic impact model for surrounding communities and businesses incorporates user cost, environmental cost, and business revenue change. To demonstrate the application of economic impact analysis concepts and procedures, a case study was developed. The scope of the study is limited to construction duration.
