Senior Hydrotechnical Consultant (Bergmann Associates, US), Formerly: Director, Progress International Consultants (Vancouver), Hydrotechnical Discipline Lead (Western North America), Hatch Ltd., Vancouver
Dr. Saied Saiedi, P.Eng., is a civil engineer with 32 years of engineering and academic experience in Iran, Australia, Malaysia, USA, and Canada. His hydrotechnical interests cover a wide range: Free surface flow (hydraulic structures, hydropower plants, sediment transport, river engineering …), coastal structures and processes, floating offshore structures, flood studies, and dam safety review. He has developed, managed, and reviewed several numerical and physical modeling works. As a private consultant and project manager, he managed 8 consultancy projects on dam and hydropower bids in Iran and served as a contract designer or adviser for various engineering firms and water authorities in Iran and Malaysia.
Dr. Saiedi designed and oversaw the construction of a flume for river and wave studies at Water Research Laboratory (UNSW, Sydney, Australia) in 1991–1992. The facility has been since used for many projects involving riverine flows and coastal waves. He also developed a numerical model for alluvial flows called COUPFLEX (see ASCE Journal of Hydraulics, May 1997). The model was one of the first efforts in computational modelling of sediment-laden flows in ‘fully coupled’ mode, followed by several modellers later.
For several years in the 2000’s, Dr. Saiedi served NAHRIM (National Association of Hydraulic Research in Malaysia) as the senior adviser for coastal engineering projects. Also, while working for PETRONAS (Malaysian national oil and gas company), he trained several groups of engineers from various engineering disciplines to enter the realm of offshore engineering through five applied courses. In 2006–2008, Dr. Saiedi conceptually designed and oversaw the construction of a large wave flume and a large wave basin at UTP (PETRONAS’ university) for applied research projects in the areas of coastal and offshore engineering.
While working in Canada and the US, Dr. Saiedi has led or participated in design and investigations for many hydropower plants (HPP) and dam facilities in Canada and overseas. Sample projects include: Site C Dam (BC, Canada), I1K Power Transmission Line (Saskatchewan, Canada), Kemano Hydropower Plant (BC, Canada), Tapoco HPP Scheme (USA), Karcham-Wangtoo & Vishnuprayag & Baspa–II HPP’s (India), Boron Mining Operations (CA, USA), Kokish River HPP (BC, Canada), John Hart Gen. Station Replacement Project (BC, Canada), Skaha Lake & McIntyre Dams (BC, Canada), Waneta Dam (BC, Canada), Brilliant Dam (BC, Canada), Similkameen Dam (BC, Canada), Seymour Dam, East Toba & Montrose HPP’s (BC, Canada), Stave Falls HPP (BC, Canada), and Nimisila Reservoir and Dam (OH, USA).
With his concurrent academic experience over the years as an Associate Professor in Civil Engineering, Dr. Saiedi has shared his vast hydrotechnical experience with professional engineers in Canada (BC) and USA (MI, NY) through short-courses. He was the Director of Progress International Consultants (Vancouver), Hydrotechnical Discipline Lead (Western North America) of Hatch based in Vancouver, and Technical Adviser (Canada) to ATB Riva Calzoni, an international provider of hydromechnaical equipment for hydropower dams. While working with Bergmann Associates, Dr. Saiedi has been involved since early 2017 in the hydrotechnical investigations for the design (proposal stage) of the Gordie Howe International Bridge across Detroit River as well as projects on dam safety review and protection of coastal structures in the US.
