IBC 17-17: Deep Pipe Pile Cell Foundations Built in Rivers for Expressway Viaduct Widening
Takefumi Takuma, Masashi Nagano and Ian Vaz, Giken America Corp., Orlando, FL

Pipe pile cell foundations are being constructed to support a new expressway interchange on a viaduct section over rivers flowing through a densely populated part of Tokyo, Japan. The state-of-the-art Gyro Press Method (rotating and simultaneously pressing in the pipe piles) was chosen to drive 60-meter (197-foot) long and 800mm (31.5-in) diameter pipe piles to minimize noise and vibration and to deal with a low overhead clearance.

IBC 17-18: The Inspection Revolution: How a Combined Above/Below Water Hi-Resolution Mapping System is Changing the Way We Assess the Condition of Marine Structures
Mark Farber and Rich Hisert, Ph.D., Innovative Mapping Technologies, LLLP (IMT), Troy, NY

Innovative Mapping Technologies (IMT) utilizes its combined multibeam-LiDAR mapping vessel to characterize structures, below and above the waterline, throughout the New York State Canal System. The high resolution, geospatially referenced, 3D models have become the standard of the inspection program, which previously used divers alone. The new program has produced more accurate and comprehensive inspections with less time on the water, resulting in a higher number of structures completed with lower costs and increased safety.

IBC 17-19: Effectiveness of Added Damping Systems for Structures in Latin America
Carlos Mendez-Galindo, Ph.D., Mageba Mexico, Mexico City, MX; Gianni Moor, Mageba USA, New York, NY; Borja Bailles, Mageba International, New York, NY

Several countries in Latin America have started to implement seismic protection systems based on advanced technologies. The main objective is always to protect people’s lives. However, the integrity of the structures and their serviceability immediately after an earthquake are key in the speed of the emergency response. Seismic damping systems provide an alternative to conventional earthquake resistance design, and have the potential for significantly reducing seismic risk without compromising safety, reliability, and economy of structures.

IBC 17-20: Structural Health Monitoring of Cable Stay Bridges as Applied on the New Champlain Bridge in Montreal, Canada
Gianni Moor, Mageba USA, New York, NY; Samy Rassy, Mageba International, New York, NY; Kleidi Islami, Ph.D., Mageba Switzerland, Bulach, Switzerland.

With the continuous optimization of design software, construction technologies and materials, structural design has taken tremendous leaps. However, demonstrating proper structural behavior and providing timely maintenance, more specifically of modern cable stay bridges, remains challenging. This paper introduces the new Champlain Bridge as a case study to demonstrate how the implementation of Structural Health Monitoring (SHM) can help ensure a structure’s full life expectancy while also being used to confirm structural models.



W-01: Evaluating Internal Redundancy of Existing Built-up Steel Members to Set Hands-on Inspection Intervals

Time:2:00 – 5:00 PM
Room: Baltimore 3/4/5

Presented By: Purdue University

This workshop will familiarize bridge engineers with newly developed provisions on how to exploit the internal redundancy of existing or new built-up steel members presently classified as FCMs in order to establish a rational hands-on inspection interval.  Built-up members meeting the provisions are internally redundant and therefore should not be classified as FCMs.  The supporting research (TPF-5(253)) and specifications/commentary with detailed examples, including setting the hands-on inspection interval, will be presented.

Speakers: Robert J. Connor, Ph.D., Purdue University, West Lafayette, IN; Francesco Russo, Ph.D., P.E., Michael Baker International, Philadelphia PA; Matt Hebdon, Ph.D., P.E., Virginia Tech, Blacksburg, VA.

W-02: International Bridge Engineering Practices

Time: 2:00 – 5:30 PM
Room: Annapolis 1/2/3

Presented By: Bridge Engineering Consultant

The objectives of this workshop are to learn of bridge engineering practices from around the world, and to provide a forum for participants to present and discuss innovative bridge design, construction, inspection, maintenance and preservation practices for addressing bridge engineering challenges and opportunities. Five to six international speakers will be invited to share their practices for information and discussion. There will be time for attendees to ask questions after each presentation. After all the presentations are completed, an “Open Forum” will be scheduled
for general discussion of topics presented and other issues of interest to the participants. International bridge engineering practices are quite varied in different parts of the world. There are many good practices and valuable lessons to be learned. Attendees of this IBC workshop will be able to take away ideas and solutions that can be applied to their daily practice of bridge engineering.

Speakers: MW. Phillip Yen, IABEE, Centreville, VA; Barry Colford, AECOM, Philadelphia, PA; Morgan Trowland, McElhanney Consulting Services, Inc., Vancouver, BC, Canada; Jiangguo Lv and Houqiang Ji, Anhui Transportation Holding Group Co., Hefei, Anhui, China; Guillermo Capellan Miguel, Arenas & Associates, Santander, Spain

W-03: (BriM) Using Bridge Models after the Design Process

Time: 2:00 – 5:00 PM
Room: Woodrow Wilson A

Presented By: Bentley Systems

Bridge Information Modelling (BrIM) is a process to plan, design, construct and manage infrastructure assets that involves creating and using intelligent 3D models. Implementation of an effective BrIM strategy that integrates people, processes and technology can greatly improve accuracy and efficiency.

This workshop will explain:

  • How BrIM technology and processes is being used on live projects.
  • How to create a managed BrIM framework using the OpenBrIM library concept.
  • How the information in intelligent bridge models can be used for construction, inspection and maintenance.
  • How this process is being implemented in the United Kingdom.

Speakers: Alexander Mabrich, Bentley Systems, Sunrise, FL; Andy Lohan; Mina Mahdavi; Ali Koc, Research and Development, Red Equation Corporation, Melville, NY; Mina Mahdavi, EnTech Engineering, PC, New York, NY.

W-04: Bridge Load Rating and Posting for State-Specific Legal Loads

Time: 2:00 – 5:00 PM
Room: Magnolia 1

Presented By: Federal Highway Administration

State laws governing truck size and weight vary from state to state, leading to the variation of legal loads allowed to operate in different States. In accordance with the National Bridge Inspection Standards, the State-specific legal loads need be considered in bridge rating and posting. The objective of this Workshop is to provide awareness to bridge engineers/load raters about the State-specific legal loads, the regulatory requirements, and the method to rate and post highway bridges for these loads.

Speakers: Lubin Gao, Ph.D., P.E. and John Berg, P.E., Federal Highway Administration, Washington, DC; Scott Neubauer, P.E., Iowa Department of Transportation, Ames, IA; Ping Jiang, Ph.D., P.E., Delaware Department of Transportation, Dover, DE
