The Civil and Structural Engineering practice of Hess Engineering Inc. was established in 1980 based on fifteen years of building and facilities design, constructions management and real estate development experience of its principal with four major corporations. In 1990, Larson Engineering of California and Dohube Structural Engineers from southern Orange County were acquired and in 1992 our main office was moved to Los Alamitos at the boundary of Los Angeles and Orange Counties in southern California. Richard Hess is a registered Structural or Professional Engineer in fourteen Pacific, Rocky Mountain and Gulf Coast states.

The personnel of Hess Engineering Inc. have extensive experience in the structural design and retrofit of residential, commercial, institutional and industrial buildings, as well as blast-resistant and geotechnical structures, supports for large dynamic equipment and vessels, ocean structures and water treatment facilities.

We have specialized in the seismic evaluation and remedial design of existing hazardous buildings, storage vessels and industrial structures, as well as supports for both architectural and mechanical non-structural elements such as equipment enclosures, office and laboratory fixtures, curtainwalls, complex glazing and ceiling systems, access floors, piping and ducts.

Our engineers actively chair and participate in SEAOC Existing Building and ASCE Structural Retrofit Standards Committee work developing new codes and design guidelines for seismic and wind design. Seismic evaluation and loss assessment reports are regularly written for a wide range of structures.

Our professional staff consists of highly motivated, experienced veterans of engineering analysis and design. We are capable of moving quickly on large or small projects using the same attention to technical detail and project management that has produced uniformly economical results for our clients.
