Leonard A. Harms, P.E.

Senior Principal Engineer

As founder of Harms Engineering, Inc. (HEI), Mr. Harms has had more than 40 years experience with civil engineering design, project management and failure analysis (forensic engineering).

His experience in civil design and project management began when he held the positions of Assistant City Engineer of Pasco, Washington (1970-1971), then City Engineer of Kennewick, Washington (1971-1975).

Subsequent private consulting work has included engineering in the following areas: water supply, storage and distribution; storm drainage and sewer systems; street design; site planning; subdivision development; construction management; structural design for residential, commercial and light industrial structures.  He has also done residential water system designs, water treatment studies and design for private and commercial water systems.

In addition to his design practice, Mr. Harms has also completed numerous total building inspections for residential and commercial structures, including assessment of structural condition, recommendations for continued or change of occupancy and Due Diligence reports for land developers.

His special interest and training in failure analysis has led to providing forensic services for hundreds of failure, negligence and accident cases, including providing expert witness during trials when required.  These cases included, but are not limited to structural failures, foundation settlements, slip and falls, mechanical and product failures, construction related failures, and electrical and product failures.
