ACI special session presentation - Case study I-635 bridge over State Ave

Just happened to come across a presentation hosted by ACI University of a presentation our engineer Ryan Koch PE made at an ACI special session in Washington DC October 2014.   Ryan's presentation gives a detailed technical overview of the design and economics of the construction of the I-635 bridge over State Ave in Kansas City KS. 

What makes this case study interesting is that there are two nearly identical parallel bridge spans offering the opportunity to compare the design and implementation of GFRP bar directly with epoxy coated steel reinforcing.   Ryan goes through details of the design implementation with Jon Karst of George Butler Associates the engineer of record for the project built for Kansas Dept of Transportation.
