Workshop Coordinator: Mike Culmo, CME Associates Inc.
Speakers: Mike Culmo, CME Associates Inc.

This workshop introduces practicing engineers to the new AASHTO Guide Specifications for Accelerated Bridge Construction. These specifications include both design provisions and construction provisions. The guide specification covers all of the most common forms of ABC in use today in the United States. The design portion of the workshop will focus on loads and load factors and design and construction of elements, connections (including seismic), and bridge systems.The construction portion of the workshop will focus on temporary works, assembly planning, and management of tolerances.

Speakers:

This workshop presents information needed for the practical implementation of lightweight concrete (LWC) for ABC projects, including an introduction to recent changes related to lightweight concrete in the AASHTO LRFD Bridge Design Specifications that simplify design and significantly improve the economy of lightweight concrete for some elements. Attendees will learn how using lightweight concrete in ABC applications can improve bridge durability and service life. The concepts of internal curing of conventional concrete mixtures by replacing a portion of the sand in a mixture with prewetted lightweight aggregate and the use of lightweight aggregate for geotechnical fill will be discussed.

This workshop will discuss programmatic implementation of Accelerated Bridge Construction. The Vermont Agency of Transportation (VTrans) will present one approach to programmatic implementation with lessons learned and results. The VTrans presentation will be followed by a “Round Table” discussion of owners about experiences with programmatic implementation of ABC.

Field-cast UHPC details connecting prefabricated bridge elements have proven to be an application that has captured the attention of owners, specifiers, and contractors across the U.S. These connections can be simpler to construct and can provide more robust long-term performance than connections constructed through conventional methods. This workshop will introduce attendees to this technology including background on UHPC, details on connection design, specification and construction considerations, as well as examples of deployed applications. This workshop is the perfect opportunity for participants to learn about this technology and to return home with the tools necessary to successfully implement UHPC connections. Presenters will encourage discussions and field questions throughout, ensuring that participant learning objectives are met.

Workshop Coordinator:
Speakers:

Foundations of existing highway and over river bridges have significant functional values. Hence, reuse of foundations of existing bridges during reconstruction or major rehabilitation of bridges can result in significant savings in costs and time. The main objective of this workshop is to introduce the draft FHWA best practice manual on foundation reuse, discuss various key case studies, and address various engineering solutions and challenges encountered during the foundation reuse process.

Afternoon Sessions

Wednesday, December 6, 2017 – 1:00 p.m. to 5:00 p.m.
Workshop Coordinator:
Speakers:

This workshop provides up-to-date information on successful implementation of several Proven Advanced Technologies listed as resources on the ABC-UTC website. These technologies have been recommended by various State DOTs across the country. Technology representatives will present recent projects supported by the states. The ABC aspects of the projects, the time savings offered by the technologies, and the overall time and cost savings for future applications will be described. Lessons learned and new ideas to further advance the ease of application and understanding of these innovative ABC technologies will be included. Available funding programs will be discussed.

Workshop Coordinator:
Speakers:

For many reasons the use of self-propelled modular transporters (SPMTs) can be one of the most effective technologies for ABC. While their use in the U.S. continues to grow, opportunities exist to further utilize SPMTs. Hear from industry SPMT suppliers, owners, and the NCHRP principal investigator on trends, benefits, uses, procurement perspectives, and upcoming AASHTO code changes specific to SPMTs for highway bridges. Identification of industry knowledge gaps and needs will be discussed in parallel with national efforts that will be pursued to better educate and implement SPMTs into ABC projects for 2018 and beyond.

Workshop Coordinator:
Speakers:

This series of talks by members and staff of the Precast/Prestressed Concrete Institute (PCI) will focus on key elements of bridge design. Some elements are covered in the AASHTO LRFD Bridge Design Specifications, while many concepts and practices for precast prestressed concrete are addressed through industry publications. PCI will discuss recent State-of-the-Art Reports. And finally, speakers will address two growing topics of interest: Spliced Girder Technology and Bridge Geometry. New developments in precast concrete will also be discussed. These topics are all covered in detail within the Third Edition of the PCI Bridge Design Manual.

W-09: Recent Developments in Steel ABC Applications

Wednesday, December 6, 2017 – 1:00 p.m. to 5:00 p.m.
Workshop Coordinator:
Speakers:

Up-to-date information will be presented on the design and construction of steel bridges using the latest design tools and technology to incorporate considerations for efficient, economical fabrication and construction. Included will be advances in assembly and erection of steel bridges for ABC projects, case studies featuring items of interest to both the Engineer of Record and the Construction Engineer, optimized steel girder implementation, changes to design of bolted field splices as adopted in the latest AASHTO design specifications, and summary of steel availability across North America.

W-10: Innovative Bridge Designs for Rapid Renewal, SHRP2 R04 ABC Toolkit

Wednesday, December 6, 2017 – 1:00 p.m. to 5:00 p.m.
Workshop Coordinator:
Speakers:

This workshop introduces the Innovative Bridge Designs for Rapid Renewal SHRP2 R04 ABC Toolkit and provides an in-depth overview of ABC issues. The workshop will cover the philosophy of why ABC should be considered in the current construction environment. Basics of ABC will be discussed, including a variety of proven methods vetted during the two demonstration projects and the eight implementation projects carried out under the SHRP2 R04 project. Lessons learned from these projects will be presented along with current best practices for ABC. The workshop will conclude with a walk through the recently completed ABC projects around the country.

W-11: Accelerated Bridge Construction in Seismic Regions

Wednesday, December 6, 2017 – 1:00 p.m. to 5:00 p.m.
Workshop Coordinator:
Speakers:

This workshop provides an opportunity for exchange of the latest information in research and implementation of ABC in seismic regions. Devising connections that can accommodate inelastic cyclic deformations and are readily constructible is the primary challenge for ABC in seismic regions. Ductile behavior is desirable under earthquake loadings for both the longitudinal and transverse directions of the bridge. The workshop demonstrates technologies for delivering bridge construction projects in weeks, rather than months, for reducing congestion, improving safety and increasing the quality of highway bridges in seismic regions.
