HDR Expands Dam, Levees, Civil Works Practice with Addition of Three Key Hires

Parul Dubey on July 29, 2016 - in News, People

HDR has recently added three industry-recognized leaders to the dams, levees and civil works practice. They are Dan Osmun, national technical advisor for dam safety and risk, and Jeff Allen, national technical advisor for heavy civil construction, both based in HDR’s Denver, Colorado, office; and  Ed Zapel, senior hydraulics engineer, based in HDR’s Seattle, Washington, office.

Over the past 25 years, Osmun has worked as the lead geotechnical engineer and project manager for major dam design projects around the world, including the 650-foot-high San Roque dam in the Philippines. Most recently, he was a senior geotechnical engineer at the U.S. Bureau of Reclamation and served on a risk leadership team that updated Reclamation’s Dam Safety Public Protection Guidelines and advised the dam safety program for its 300-plus dams, including the Hoover and Shasta Dams.

Allen is a pioneer in the use of roller compacted concrete for the construction of dams. Recently serving as construction liaison for the U.S. Bureau of Reclamation, his career spans more than 30 years in dam and water resource design and construction. With over 25 years as a contractor and many years as president of ASI (now ASI Constructors), his background encompasses owner, engineer and contractor perspectives. Allen brings insight and lessons learned from over 200 dam projects throughout  the world, including key involvement on notable projects across 27 states and 15 countries.

Zapel is a hydraulics expert with previous leadership roles at the U.S. Army Corps of Engineers’ Seattle District and most recently Northwest Hydraulic Consultants. Zapel has more than 28 years experience, and has played key roles in the design and analysis of hydropower, flood control and water supply dams, as well as physical scale modeling of hydraulic structures. Key projects include the redesign and reconstruction of the Mud Mountain Dam outlet works on the White River in Washington state, and spillway and dam modifications to reduce total dissolved gas during spill events for the federal Columbia River power system dams operated by the USACE. He has also designed fish passage and collection facilities for more than a dozen federal and private utility dams throughout the Pacific Northwest, and has inspected hundreds of miles of federal and non-federal levee structures and designed repairs for flood-damaged levees across the entire northwestern United States, California and the Southwest.
