Josh Cackley

Dam Safety Program Manager, US Army Corps of Engineers

I earned by BSCE from Purdue University in 2003. I have worked for the US Army Corps of Engineers, Rock Island District since 2003, working in the structural design section for 12 years before becoming the District's Dam Safety Program Manager in 2015. After the historic flooding in the spring of 2019, the City of Davenport, Iowa requested assistance from the Corps to investigate the cause of the HESCO failure in order to improve their flood plan for future high water events. I lead the investigation and performed the engineering evaluation for the Corps.

Chad Stewart

Construction Risk and Safety
Cobb Strecker Dunphy & Zimmermann

Chad joined CSDZ in 2015 and brings over 20 years of construction experience to his clients. He began his construction journey in the 1990’s as a union carpenter apprentice and, after achieving Journeyman status, he moved into the site Foreman role. Over the next 7 years, Chad concentrated on construction management where he consulted with organizations on a nationwide scale. His talent was focused on developing strategies to measurably improve construction risk objectives for increasing profitability potential, improving efficiencies and reducing costs. Chad was the Safety and Training Manager for a national contractor before coming to CSDZ where his attention was on gas/oil transmission and distribution, utilities and municipal construction. During this time, Chad earned the "National Safety Person of the Year" award from the Distribution Contractors Association (DCA) in 2013.

Steve Zeets

CEO and Founder

Whirrx is a drone company built by surveyors for surveyors. Whirrx was born after our Terraplane customers began asking to purchase the drone system due to our unique ability to achieve 1cm vertical accuracy in a survey deliverable. We provide a standardized drone system, along with cloud software processing and training to make drones finally work for you, the surveyor.

Daniel McGehee

The University of Iowa

Daniel McGehee has been obsessed with car crashes for over 20 years. He is interested in every aspect of them - from how, when and why they occur, to technologies for avoiding them altogether. His driver performance, distraction, and technology development research has led to innovative, interdisciplinary collaborations involving engineering, medicine, and public health. McGehee's research has helped policy makers to improve government safety standards, as well as state and federal laws. While the first generation of safety systems were designed to help protect occupants in cars, his research deals with preventing or reducing the severity of crashes. Such technologies will ultimately lead to higher levels of automation on our roads.
