Cary Zarate

VP, Estimating (CHI)

Cary Zarate is a problem solver. He finds that preconstruction is the perfect field to solve cost issues before they arise and build trust within a collaborative team early in the process, setting projects up for success.

Leading W.E. O’Neil’s preconstruction and estimating group in Chicago, Cary works with his team to push us ever forward in accuracy and reliability. His preconstruction training and development encourages best practices that drive consistency and provide excellent service to our customers while making the best value decisions.

The most rewarding part of working in our industry is the people, relationships, and friendships that I have made. The AEC industry in Chicago is a very tight knight group that includes all types of personalities, from creative to engineer-minded. The relationships I have formed over the years have been very gratifying.
