IBC 22-01: UHPC Repair of Steel Columns in the Walnut Tunnel in Philadelphia
Michael McDonagh, P.E., P.Eng., Steelike, Inc., Springfield, VA; Joseph Sirignano, P.E., VMA, Alfred Benesch & Company, Allentown, PA
Time: 2:00 PM
The Pennsylvania Department of Transportation (PennDOT) rehabilitated the bridge structure located within SEPTA’s Walnut Tunnel conveying the Philadelphia airport regional rails. A series of steel columns supporting the bridge/tunnel structure exhibited advanced section loss. The designer repaired the deteriorated steel columns with ultra-high performance concrete (UHPC) the first such application in North American transportation infrastructure. The contractor and UHPC supplier implemented unique mixing and placement techniques, including using a 70-ft tremie to place the UHPC.
IBC 22-02: The Smart Hybrid Bridge – Time to Innovate in Bridge Management Policy and Practice
Brian Westcott, Ph.D., Intelligent Structures, Inc., Menlo Park, CA; Lawrence Kirchner, P.E., S.E., TranSystems, Chicago, IL
Time: 2:30 PM
Productive management of bridge infrastructure assets requires digital information. Depending primarily on visual inspection provides limited information and conservative bridge ratings. Resulting bridges are under-utilized, and unproductive. A smart hybrid bridge policy combines visual inspection and continuous bridge performance measurement for a more accurate assessment of the state of a bridge. A case implementing Smart Hybrid Bridge Policy on two NYS load restricted bridges resulted in better performing bridges with decreased annual budget costs.
IBC 22-03: Cast-In-Place ABC Solution – The InQuik Bridge System Technical and Projects Presentation
Logan Mullaney, InQuik Pty Ltd., Pyrmont, NSW, Australia
Time: 3:00 PM
The International Award winning InQuik Bridge System, is a modular reinforced concrete bridge system, however very different from typical bridge systems.
The InQuik System uses pre-fabricated, pre-engineered and certified components that have the formwork and reinforcement, however no concrete. These components are self supporting and are simply transported to site, easily lifted into position and filled with concrete with limited skills.
This revolutionary system has been used in over 150 projects and in this session, we will discuss how the InQuik System works, along with discussing the research programs that have been completed by Universities and the AASHTO Verification process. On top of this we will discuss range of projects that the system has been used on, including Accelerated Bridge Replacement projects, projects using local county and contractors, and Flood / Fire recovery.
With consideration of the recently released Federal Bridge Formula Program, we will also discuss how the InQuik System has been key in a 24-month program to deliver 300% the usual amount of annual bridge projects in Australia. We will explore the learnings and challenges of such a program in delivery with Supply chain constraints, high infrastructure demand, tight labor market, rising prices and availability. In this session you will learn how InQuik and several county’s have ensured their Fixing County Bridges program is delivered on time, within scope and within budget whilst navigating the challenging market.
3:30 PM – Coffee Break
IBC 22-04: Japan’s Proven Solution to Prevent Unseating of Bridges During a Seismic Event
Hideto Kida, Dr. Eng., P.E., Technical Research Institute, SHO-BOND Corporation, Tsukuba, Ibaraki, Japan; Benjamin Z. Reeve, Structural Technologies, Fort Worth, TX; Fujihiko Hayashi, Mitsui & Co., Tokyo, Japan
Time: 4:00 PM
Unseating prevention is a critical step in bridge seismic retrofit projects, not only ensuring life safety but also allowing post-earthquake functionality and serviceability.
Japan’s historical experience with large earthquakes offers numerous lessons learned about bridge unseating, from which practical solutions have been developed.
SHO-BOND’s innovative seismic devices, applied to numerous concrete and steel bridges in Japan, provide backup to existing bearings, restrain higher loads, and enable prompt recovery of bridges following a large seismic event.
IBC 22-05: Bridge Rehabilitation with Ultra-High Performance Concrete Bridge Overlays
Peter Seibert, P.Eng. and Gil Brindley, P.E., UHPC Solutions North America, Orange, NJ; Jerry Reece, WALO Civil, Birmingham, AL
Time: 4:30 PM
Ultra High Performance Concrete (UHPC) Bridge Overlays are an ideal solution for bridge agencies to rehabilitate bridge decks as a long lasting, cost effective alternative to full deck replacement. Only recently, UHPC overlays were installed in a few select States across the US.
The enhanced durability and flexural capacity of UHPC overlays are key to the solution for extending the service life and performance of deteriorating bridge deck structures. When installed with a Thin Lift UHPC Paver, this rehabilitation method helps bridge owners to accelerate bridge repairs by shortening the total construction time and by minimizing traffic interruptions.
This paper will describe the fundamentals of the UHPC technology, material properties and various UHPC overlay design details. Key success factors and construction methods from a contractor’s perspective will be explained. Bridge owners will be informed about risk management, quality, and specification considerations of UHPC overlays. Detailed reviews and lessons learned of several recently completed US and Swiss projects will be discussed.
IBC 22-06: Structural Health Monitoring of the Canakkale Bridge in Turkey, the Largest Monitoring System for the Longer Bridge in the World
Time: 5:00 PM
Stéphane Joye and Marcel De Wit, Sixense, Nanterre, France
The 1915 Canakkale bridge in Turkey is the longest suspension bridge in the world with its 2023m main span. Sixense is installing the biggest SHM System ever installed on a bridge with more than 1000 sensors. This will allow to monitor the environment of the bridge, its structural behavior and its ageing. Data will also allow to predict the evolution and anticipate maintenance.

W01: Transportation Welding Workshop
Justin Ocel, USDOT-FHWA, Baltimore, MD
Time: 2:00 PM – 5:30 PM
The objective of the workshop is a workforce development tool to educate early career engineers on the ins/outs of welding they may encounter in their careers. Typical college curricula do not get into anything beyond how to design a weld for strength, and new engineers are quickly faced with having to approve/accept welding processes, joints, filler metals, welding procedures, procedure qualifications, or inspection results in accordance to AWS welding code with no knowledge of how those codes work, or what they cover. After the workshop they should have a kickstarted understanding of how to navigate the AWS welding codes and feel much more comfortable in the oversight role of transportation welding.
