Engineering Delaware's Future Since 1970
Call Us: 302.697.7694


Diamond State Engineering was originally incorporated in 1969.

From 1970 – 1981, we originally provided Electrical and Mechanical Design & Engineering Services, later expanding our technical staff to include Structural Engineering, Architectural Design and limited Construction Management services.

In 1981, D.S.E. merged with John McCune, AIA and Associates and re-incorporated as Diamond McCune, Inc. providing full A&E services from offices in Dover and Wilmington. After John McCune’s retirement in 1989,we continued to provide A&E services as the Diamond Group, Inc.

In 1990, the Diamond Group consolidated offices to Odessa, Delaware which the company designed and built.

Diamond Group merged with BM2OR in 2000 and relocated from Odessa to Wilmington as Becker Morgan Group.

As our consulting agreements with BMG concluded in 2003, the decision was made to reactivate the original firm, Diamond State Engineering, and again offer our extensive Mechanical, Electrical, Plumbing Engineering and Construction Services.

In 2008, Mechanical Construction was added to compliment the Design/Build offering of Diamond State Engineering.
