About O’Neal

O’Neal Inc. is an integrated engineering and construction company providing comprehensive services to our clients. Since 1975, O’Neal has been successfully delivering complex capital projects. As an EPC contractor, we focus on the business of project delivery: integrating overall project planning, design, procurement, and construction to create cost-effective capital solutions.

Last year O’Neal acquired DME, an engineering firm specialized in serving the regulated life sciences industry, to enhance O’Neal’s process design and MEP engineering services for biopharm manufacturers: cleanroom design, critical utilities, pharma/bio process systems, laboratories and manufacturing facilities.
