DMc Engineering is a local, talented design firm providing civil engineering, planning, and surveying/mapping services to the local community. DMc Engineering opened its door in Irvine, CA over 25 years ago. Derek J. McGregor, PE, started DMc Engineering in 1987 with a simple vision, "Communicate - Coordinate & Calculate." These are the (3) C's of DMc Engineering, as they are essential to successful engineering, survey, and construction project management. 

Our local presence and project experience have helped us build our client base throughout several counties, with a wide range of project types for agencies and the private sector. By this and word-of-mouth, DMc has been successfully growing as a firm since its inception a quarter of a century ago.

​Over time we've expanded our services to include Construction Management, making DMc a full-service firm.
