Contract signing for Outer Drive Bridge
From his humble beginnings as an office boy in the early 1900's at the architectural firm of Daniel H. Burnham, William E. O'Neil could not have imagined the world of innovation and technology that has shaped the way we do business today at W.E. O'Neil. We exceed our clients' business objectives by utilizing what we have learned throughout our history and applying new technologies and modern construction techniques. All the way through this process of innovation and automation, one thing has remained constant throughout a century of change: the relationship between the client and contractor that is still based on the traditional family values instilled by our founder William E. O'Neil.
