With promising funding trends and KOA’s long-term client relationships, we anticipate a significant increase in our pipeline of work in this growing megaregion.”

KOA President and CEO Min Zhou added, “I challenged myself and my team to think out of the box relative to future growth plans with a focus on pursuing large-scale projects; strengthening our transportation disciplines; investing in technology and innovation practices; and expanding career opportunities for our diverse workforce. Becoming part of the Lochner organization will help KOA to advance these mutual growth objectives, while leveraging the talent, client reach, and operational efficiencies of the combined companies.”
