The Firm
Delta Engineering, Est. 1984
Based in Del Mar, California, Delta Engineering provides comprehensive structural engineering services to clients throughout the United States. We deliver structural design for commercial, industrial, educational, and governmental facilities, as well as high-end custom residences. We are licensed in 14 states, Washington D.C., and British Columbia.
Our approach treats every set of plans as if it were a shop drawing. That has earned us a reputation for minimizing RFIs, reducing field errors, and keeping projects on schedule.
Delta Engineering is also a selected consultant to the Division of the State Architect, serving as structural plan-review checker for the San Diego regional office, helping educational projects navigate the approval process with confidence.
