Mechanical Engineering

Orion’s team of mechanical engineers combines the education of the Southeast’s finest universities with the practical knowledge gained only through personal experience in the construction and plant operations environments. Years of construction site experience allow our mechanical engineers to consider constructability issues as the project develops, while their operations experience helps them to consider designs from the client’s perspective. This combination of perspectives produces final projects that are as easy to operate and maintain as they are to build.

Orion Engineers & Constructors has an extensive library of equipment specifications and standard data sheets to supplement those of our clients. We also supply our engineers with all the tools necessary to expedite quality and cost effective designs, including the engineering software, CAESAR. From piping systems to glass-lined reactors, Orion’s mechanical engineers are prepared to fulfill our clients’ needs.
