Celebrating a CENTURY of valuing people and building dreams!

This once-in-a-lifetime milestone is made possible by the commitment of our employee-owners and through relationships built over time with our clients and partners.

Aerospace, Technology, Manufacturing

W.E. O’Neil has been a leader in the aerospace, technology, and manufacturing markets since the company was founded in 1925. We remain committed to maintaining an understanding of sophisticated construction applications that can meet the challenges of today’s building technology demands.

This dedication to the vital needs of technology and development is further demonstrated by our outstanding performance in constructing laboratories, secure spaces, cleanrooms, and advanced manufacturing. Whether constructing SCIFs (Sensitive Compartmented Information Facility) for a defense contractor, a data center for a state-of-the-art office building, or a highly technical manufacturing facility, our work demonstrates an understanding of the special challenges inherent in building for the vital needs of the future.
