ASCE has honored Hossein Bahmyari, Ph.D., P.E., BC.GE, F.ASCE and Clint H. Smith, P.E., M.ASCE, with the 2026 ASCE President’s Medal.
Bahmyari is recommended for his outstanding contributions to civil and geotechnical engineering through technical excellence, innovative infrastructure design, and dedicated service to ASCE and the engineering community. He exemplifies leadership, mentorship, and commitment to advancing resilient and sustainable public infrastructure.
Over a career spanning more than two decades, Bahmyari has demonstrated exceptional leadership and innovation in advancing sustainable and resilient infrastructure design. During his tenure with Kiewit Engineering Group, he played a key role in the design and implementation of complex infrastructure projects across the United States, Canada, and Mexico. His technical insight and leadership contributed to the success of multiple large-scale transportation and water projects, including the Omaha Riverfront Redevelopment Project, which received the 2025 ASCE Outstanding Civil Engineering Achievement Award. These accomplishments exemplify his ability to integrate sound geotechnical design with practical construction applications, resulting in safer and more resilient infrastructure.
As a senior lead geotechnical engineer at Twining Inc., he continues to shape the built environment through his work on transportation, water, and structural projects across California. His designs emphasize public safety, long-term performance, and environmental stewardship, reflecting his deep commitment to engineering excellence and sustainability. In addition, he has collaborated with multiple state transportation departments and public agencies to provide advanced geotechnical analyses and design reviews, improving project outcomes and setting higher standards for infrastructure reliability. Beyond his technical achievements, Bahmyari has made a lasting impact through his service to ASCE at both local and national levels.
Smith is a water/wastewater project manager with Halff in Austin, Texas, working on large-scale watershed studies, water and wastewater modeling, water and wastewater system master planning, water and wastewater line design, and surface water quality analysis projects. He is commended for leading projects that impact thousands of lives, mentoring the next generation of civil engineers, and paving the way for a wider group of people to see themselves in our remarkable, important profession.
He has worked on a variety of projects ranging from capital improvement plans, feasibility studies, and hydraulic model creation/updates. He has been modeling hydraulic systems for six years and has utilized programs like InfoWater Pro, WaterGEMS, Infoworks ICM, and others for these analyses. His experience includes environmental permitting, water and wastewater system modeling, storm water modeling, water transmission and wastewater conveyance design and water and wastewater systems master planning.
Smith is a dedicated member of ASCE, serving as chair of ASCE’s Committee of Younger Members and ASCE Austin Branch Younger Member director and JEDI chair. He also serves as vice chair for MOSAIC and the EWRI Technical Committee on Drinking Water Supply, Treatment, and Distribution and Stormwater Filtration.
He is an active member of the American Water Works Association, serving as the local TAWWA Seminar planning co-chair, and is on the AWWA Standing Committees for Asset Management and Engineering Modeling Applications. He is also a member of the Water Environment Association of Texas and serves on both the Hydraulic Modeling committee and the Young Professionals committee and participates in the Transportation Research Board committees on water resources engineering and geospatial and visual analytics.
Smith received the A. Ivan Johnson Award for Young Professionals from the American Water Resources Association in 2023 and was named an ASCE New Face of Civil Engineering in 2025.
The ASCE President’s Medal recognizes the accomplishments and contributions of eminent engineers to the profession, the Society, or the public.
