Bridge Design and Construction Engineering firm, Finley Engineering Group (FINLEY) congratulates Alex Randell, E.I., Bridge Designer at FINLEY, Marcelino Aguirre and H. R. (Trey) Hamilton, P.E., Ph.D. Associate Professor Structural Engineering Group at University of Florida on winning the 2017 Post-Tensioning Institute Kenneth B. Bondy Award for the Most Meritorious Technical Paper on the Effects of Low Reactivity Fillers on the Performance of Post-Tensioned Grout.The PTI Technical Advisory Board presents awards annually to individuals who have made a significant contribution to the PTI body of knowledge. This award was presented at the 2017 PTI Convention Awards Dinner.

This study was initiated by the Florida Department of Transportation (FDOT) because of the issue of post-tensioning tendon corrosion. The research team was tasked with studying, reproducing and determining the cause of soft grout. After an exhaustive study, the team isolated the issue and provided recommendations for improving the performance of PT grouts.  FDOT has recently revised its post-tensioning policy and has specified the use of wax to fill all external tendons and selected internal tendons.

Alex completed this research during his graduate studies at the University of Florida and he is an ASBI Certified Grouting Technician Training PTI Level II. For the past 3 years, he has worked at FINLEY on projects including the Bayonne Bridge Navigational Clearance Program Approaches in New York, the I-49 Segment K Phase 2 Interchange in Louisiana and the Road 1 Motza Bridge in Israel.
