DOWNLOAD EBOOKThe National Bridge Inventory shows that more than 480,000 bridges that serve the U.S highways are of a median age of more than 42 years and a design life of 50 years; out of which, approximately 14 and 16 percent of the bridge inventory falls into the functional and structural deficient categories, respectively. In a mature infrastructure system, upgrade, repair, or replacement requires either restriction or closure of those parts of the system. Traffic disruption during maintenance and construction activities frequently results in disruptions to local economies and communities; and raises issues of safety and congestion. The use of traditional technologies and techniques for infrastructure rehabilitation are not effective enough to mitigate these disruptive effects of rehabilitation work. A systems approach to accelerating infrastructure construction is required to mitigate the impact of the extensive rehabilitation activities that are likely to take place in immediate future. The decision making system proposed in this report uses Analytical Hierarchy Process and provides the decision maker with a tool to quantify the qualitative trade-offs between various objectives to extract a single set of weights which reflect the level of importance of each of the factors in the overall decision making process. This system will thus provide the decision makers an excellent and transparent tool to make decisions regarding choosing an optimal holistic strategy for decision making.

DOWNLOAD EBOOKThe 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

DOWNLOAD EBOOKIn 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.

DOWNLOAD EBOOKBy 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.

DOWNLOAD EBOOKDecision 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.
