O'Connor was recently ranked 79th on the Engineering News Record's (ENR) annual published Top 100 CM-for-Fee firms. This is a significant milestone for O'Connor, as it is the first time ranking in the top 100.

Much of the revenue growth of the firm to make the list is attributed to the O'Connor's first strategic plan, implemented just over 2 years ago. As a result of the plan's successful execution and targeted revenue goals, O'Connor saw record revenue profits in 2008.
