College to Participate in Buchanan County Bridge Openings

The College of Engineering will participate in two Ultra-High Performance Concrete bridge openings November 10 in Buchanan County, IA.

Ribbon ceremonies will be held at 11:00 a.m. in Hawkeye, IA, and at 12:30 p.m. in

University of Iowa will be Alec Scranton, dean; Hosin (David) Lee, professor of civil and environmental engineering and head of the Laboratory for Advanced Construction Technology (LACT); and Downing Thomas, associate provost and dean of international programs.

Others participating in the ceremonies will be Brian Keierleber, Buchanan County Engineer; the Hon. Brian Schoenjahn, Iowa Senate District 32; the Hon. Bruce Bearinger, Iowa District 64 Representative; Gary Gissel, Ellen Gaffney, and Don Shonka, Buchanan Counter Supervisors; Gerald VandeVorde, mayor of the city of Hazleton; Karen Bob, FHWA division administrator; Andy Wilson, FHWA team leader; Byung-Suk Kim, senior research fellow and former vice president of the Korean Institute of Civil Engineering and Building Technology (KICT); Changbin Joh, research fellow of KICT; Kyungtaek Koh, research fellow of KICT; and Krista Taylor, vice president of Taylor Construction, Inc.

The Hawkeye UHPC bridge is the first K-UHPC bridge built in the U.S.  Six bridge girders were fabricated and cured at the backyard of Buchanan County's Secondary Roads Department during Summer 2015.  There were transported and installed at the bridge site in just one day.  The project is an example of Accelerated Bridge Construction (ABC) through collabroations among Buchanan County, Korea Institute of Civil Engineering and Building Technology (KICT) and the Laboratory for Advanced Construction Technology at the Universityu of Iowa.

 LACT was established with support from the Asphalt Paving Association in Iowa (APAI), Construction Materials Testing (CMT), Korea Institute of Construction Technology (KICT), and LL Pelling Co.  The laboratory helps member institutes and companies develop and implement their innovative new construction technologies in practice by performing objective laboratory testing and field evaluation.
