Our History

We maintain the same commitment to quality construction established in 1908 by Ernest DiSabatino and Sons, Inc.


EDiS was founded in Wilmington, Delaware in 1908 as masonry contractor Ernest DiSabatino and Sons, Inc. From that time until the middle of the 1940′s Ernest DiSabatino and Sons, Inc. worked in the Wilmington area, developing a reputation for quality masonry construction. During that period, the company also developed an expertise in the concrete and carpentry trades. It was a natural progression for the organization to expand its capabilities to include general contracting. From 1945 to the early 1970s, the organization provided general contracting services while striving to maintain their reputation for providing clients with quality construction projects.

In the early 1970s, a new form of construction project delivery, construction management, was developed. Realizing construction management was an improvement over the traditional methods, the management of Ernest DiSabatino and Sons, Inc. decided to develop the expertise to provide the new service. EDiS Company was created to provide construction management services and capabilities to provide CM – Agent, CM – At Risk, and Design-Build services.

Since then, EDiS has continued to provide construction management services to clients in Delaware, Pennsylvania, Maryland, and New Jersey. To date, EDiS’ construction volume exceeds $3.75 billion worth of work in place. EDiS continues to refine and improve its construction management services, maintaining the same commitment to quality construction established in 1908 by Ernest DiSabatino and Sons, Inc.
