Our professionals have planned, designed, permitted, constructed and operated many of the most critical water, wastewater, and sewer facilities implemented in the Southeastern U.S. in the past 25 years.  Today our clients face common challenges with the need for exceptional customer service coupled with greater accountability, stricter regulations, staffing challenges, exposure to new technologies, and shrinking budgets.  Most importantly, because of the experience level of our key staff members, we are able to immediately engage and provide innovative solutions without the research and analysis that it may take other firms.

We can take any public works and utility project (including civil sitework, roads and parking, building structures, concrete structures, process equipment, piping, valves, etc.) from concept through planning, financing, design, construction, start-up and training. Whether Constantine Constructors builds the project or provides expertise for an alternative to traditional design-bid-build projects, our experience as a licensed contractor provides our clients with an invaluable resource.
