About the Speakers

KEYNOTE PRESENTER
Robert J. Connor, Ph.D., PE
Jack and Kay Hockema Professor in Civil Engineering - Lyles School of Civil Engineering
Robert Connor is the Jack and Kay Hockema Professor of Civil Engineering in the Lyles School of Civil Engineering.  He has conducted research in the area of fatigue, fracture, and redundancy that has resulted in numerous changes to the AASHTO and AREMA specifications.  He is routinely called upon to assist owners with various issues in their steel bridge inventory. 

Variability in NDT Data: What Does it Mean and is it Time to Raise the Bar for Our Industry?
The bridge industry routinely relies upon various forms of NDT (visual, UT, RT, etc.) to make decisions regarding the condition of a component.  A current  example is the implementation of the current FHWA Memo focused on NDT of NSTMs with CJP welds in T1 steel.  Performance testing conducted by the S-BRITE Center at Purdue University indicates considerable variability exists in results reported by NDT technicians.  This presentation will present results of the performance testing and make suggestions on how to improve reliability of NDT. 

Greg Hasbrouck
Complex Bridge Technical Director - Parsons
Greg Hasbrouck is a Complex Bridge Technical Director in the Chicago office of Parsons Corporation. He has 20 years of complex and long span bridge design experience including the design of tied-arch, cable-stayed, truss, segmental box girder, and steel plate girder bridges and large river pier foundations. Greg earned his bachelor’s degree in Civil Engineering from Duke University and his master’s degree in Structural Engineering from Princeton University. Greg is the lead structural engineer and Engineer of Record for the new IA 9 / WI 82 truss bridge over the Mississippi River.

Truss Type Selection and Redundancy for the IA 9 / WI 82 Black Hawk Bridge over the Mississippi River
The IA 9 / WI 82 Black Hawk Bridge over the Mississippi River is being replaced with a new fully redundant cantilever through truss bridge with a 778 ft main span. The new truss design maintains the historic nature of the existing bridge’s peaked truss design while providing a much wider roadway and longer main span to increase mobility at the site. Unique challenges of the design include eliminating uplift from the unbalanced span layout for the three span truss, constructability of the long span over the navigation channel, and providing a fully redundant truss design. 

Meg Kindelin, AIA
Architect - JLK Architects
Meg Kindelin, AIA, is President and Owner of JLK Architects.  She has 25 years of experience in Architecture, History, and Preservation and has led restoration consultation and design for over 30 bridges and infrastructure projects.  She brings a deep understanding of architecture, preservation and regulatory processes to her work and navigates complex requirements with ease. An established leader in preservation, Meg sits on committees for Landmarks Illinois and the Illinois State Historic Preservation Office. 

Riveting Questions: Navigating the SIO and Rehabilitation of Historic Steel, Concrete, and Masonry Bridges
Federal funding is flooding us with projects to renovate or reconstruct bridges, aqueducts and other structures that are over 50 years old and deemed historic by the US Government. Funding and Age combine to trigger not only Section 106 /4f review but also the engagement of qualified Historic Preservation Architects to consult on treatment of the structure.  Following the Historic Standards is required to secure funding. SIO Qualified staff is needed to guide the restoration and rehabilitation efforts of structural elements, spans, abutment walls, bridge houses, lighting, railings.

This three-part presentation will show how to identify and address problems and concerns with steel, concrete and masonry historic bridges.

Bridge Rating, Shear and Strengthening Assessment of Kishwaukee I-39-River Bridge Utilizing Proof Load Testing and Field Verified Finite Element Analysis
This study focuses on evaluating the performance of the I-39 Kishwaukee bridge, a post-tensioned concrete box girder bridge constructed in 1978, through AASHTO MBE direct rating methods derived from proof load testing. In addition, The Modified Compression Field Theory (MCFT) method, endorsed recently by the Federal Highway Administration, is applied to assess shear capacity, considering various factors. The findings indicate that the bridge's concrete shear capacity exceeds applied forces, and the use of post-tensioning systems in rehabilitation significantly reduces deflection and minimizes tensile strain on the shear key.

Accelerated Design for Accelerated Construction: Emergency Superstructure Replacement
On January 3, 2022, Bridge 550940 over Apalachee Parkway in Tallahassee, Florida was struck for the third time by vehicles. Within 48 hours, the bridge was inspected, shoring plans developed, load rating performed, and repair alternatives for solutions ranging from girder replacement to superstructure replacement prepared. The Florida Department of Transportation (FDOT), ultimately decided to move forward with a superstructure replacement utilizing a through plate girder structure. The entire spans were replaced during a short duration closure to minimize disruption to rail and commuter traffic.

This presentation will provide a history of the bridge along with a summary of prior repairs completed after two earlier collisions in 2019 and 2021.
