We had the honor of presenting on two topics at the 2025 Civil Engineering Professional Development Seminar (CEPDS) at Purdue University. Mark Chmeliwskyj, PE, and John Lightner, PE, from our Program Management team, shared how alternative delivery methods like Build-Operate-Transfer (BOT) are reshaping public infrastructure. Bryan Wright, PE, SE, our Bridge Design Department Head, discussed his work on the rehabilitation and restoration of Indianapolis’ 30th Street historical arch over the White River.

In “Taking the LEAP with BOT,” John and Mark explored how alternative procurement approaches like Build-Operate-Transfer (BOT) help align vision, funding, and delivery. They highlighted real-world examples from our Owner’s Rep work and our role in delivering water and wastewater support to the LEAP innovative district to show how strategic coordination keeps complex programs moving forward.

Bryan’s presentation, entitled “The 30th Street Historical Arch. A complex restoration complicated by unforeseen circumstances and site conditions,” discussed how the 30th Street historical arch rehabilitation and restoration sought to remove the degrading existing arch rings and replace the superstructure, reusing the existing limestone blocks and railing. Once construction began, complications arose from originally unknown construction techniques and lack of existing plans that turned this construction project into essentially a design build project. The presentation encompassed work leading up to plan development and construction and how issues in the field were addressed.

Thank you to the CEPDS organizers for another great event! We are grateful for the opportunity for our team to share their experience and project knowledge with peers and students!
