Our Company


The Constantine Group was founded in 2002 to fill a gap in the municipal utility market - providing superior technical expertise while working in partnership with our clients to focus on their individual needs. The 2009 acquisition of the like-minded firm, ADL Engineering (founded in 1993), allows Constantine to provide a broad range of engineering services for clients throughout the Southeast, including Potable Water Engineering, Wastewater Engineering, Utility Master Planning, Capital Improvement Program Management, Subsurface Utility Engineering, Electrical Engineering, Construction Management, Site-Civil Engineering, Modeling and Software Solutions, GIS Mapping, Natural Gas Utility Work, Public Works, Industrial Process Design, and Emergency Response Work.

Growing quickly, Constantine expanded to include Construction and Management Services. To maintain our spirit of partnership, Constantine has established offices convenient to our clients throughout the Southeast in Alabama, Florida, Georgia, and South Carolina.
