Rimah I. Nazzal, S.E.

Mr. Nazzal has over 25 years of experience in structural evaluation, analysis and design, and project management of a wide variety of facilities. As the Principal in charge of the Las Vegas office, his responsibilities include the day to day operations, business development and staff supervision in addition to the technical engineering by performing seismic evaluations of structures, selection and design of lateral force resisting systems along with foundation systems, and preparation of construction documents and specifications.

During the past three code adoption cycles in the Las Vegas valley, Mr. Nazzal has been very active in the local review process of the International Building Code (IBC). As past president of the Structural Engineers Association of Southern Nevada (SEASoN), he has participated extensively with local agencies and engineers in the development of the local amendments to the IBC. He has specialized expertise in the use of engineering software for computer simulation and analyses of frames and buildings such as RISA-3D, ENERCALC, STAAD/Pro and RAM Structural System. Mr. Nazzal is proficient in supporting software such as CAD, project schedulers, spreadsheets and word processors. His practical knowledge of the International Code Council - International Building Code (IBC), American Society of Civil Engineers - Minimum Design Loads for Buildings and Other Structures (ASCE 7), American Concrete Institute - Building Code Requirements for Structural Concrete (ACI 318), and American Institute of Steel Construction - Steel Construction Manual makes him an asset to Risha Engineering's structural team.
