Book Description
ABSTRACT: The Federal Highway Administration's (FHWA) "Every Day Counts'' initiative aims to shorten the overall project delivery time, enhance safety, and protect the environment both on and around construction projects. Using innovative planning, design, and construction methods, Accelerated Bridge Construction (ABC) techniques reduce on-site construction time for new or replacement bridges. One aspect of ABC is Prefabricated Bridge Elements and Systems (PBES), where bridge components are fabricated offsite to reduce on-site construction activities. Many state departments of transportation, including Florida DOT, are currently making efforts to implement PBES for their bridge construction projects. The purpose of this research project was to investigate other states standards and to evaluate them for possible implementation in Florida. An exhaustive search was made, and new literature was reviewed, to learn about current DOT standards and practices. The search revealed that the states with the most prefabricated bridge standards or activities are as follows: Utah, Alabama, Texas, Minnesota, and a collaboration of Northeastern states. These standards were reviewed for details such as the presence of post-tensioning, joint types, design load, and inspectability. The three standard bridge types that show the most promise for adoption by FDOT are: Florida DOT District 2s Truncated "Florida I-Beam'' (FIB), Minnesotas Inverted Tee Beam, and PCI's "Northeastern Extreme Tee'' (NEXT) Beam. A summary of the findings, including advantages and disadvantages of the bridge systems, is included in this report. Also included is a comprehensive list of web links to standard drawings from all state DOTs, which could also be helpful to expedite other research that involves standards and bridge construction/design practices.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis Report 324: Prefabricated Bridge Elements and Systems to Limit Traffic Disruption During Construction assesses and documents the use of innovative prefabricated elements and systems and assesses its effects on on-site construction time and cost, closure time, and environmental impacts. The synthesis report also looks at the use of fiber-reinforced polymers and other advanced materials and new technologies that are gaining in popularity but are still in the experimental stages.

Book Description
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.

Book Description
Prefabricated components of a bridge produced off-site can be assembled quickly, and can reduce design time and cost, minimizing forming, minimize lane closure time and/or possibly eliminate the need for a temporary bridge. This document has been developed to promote the use of prefabricated elements and systems in bridges and focuses on 'Connection Details' as part of accelerated construction projects. Accelerated Bridge Construction is one of the prime focus areas of the Office of Infrastructure of Federal Highway Administration. It focuses on a need to create awareness, inform, educate, train, assist and entice State DOTs and their staff in the use of rapid construction techniques. This document represents the State of the Practice at this time with respect to connections between prefabricated elements in accelerated bridge construction projects. Most of the details were obtained from State Departments of Transportation, industry organizations, and private consultants. This information contained herein should be used to develop designs and determine which details would be appropriate for accelerating bridge construction projects.

Book Description
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
