GEI Consultants, Inc., has been awarded several contracts through its Denver office for a variety of geotechnical, environmental consulting and planning services related to the dam safety and operations in Colorado.
Included are updates to the U.S. Bureau of Indian Affairs' (BIA) dam safety handbook, rehabilitation design and construction at the Hodgson-Harris Dam reservoir rehabilitation project and a dam inundation map for Tucker Lake.
GEI said the objective for its work on BIA's Safety of Dams Program Handbook is to integrate a "risk-informed decision process" congruent with the Department of Interior's Public Protection Guidelines.
The updates will also incorporate current industry and BIA standards with policies and guidelines related to risk assessment, safety inspections, engineering evaluations, design and construction processes, permitting, emergency management, operation and maintenance, warning systems, dam security and training.
Meanwhile, the company's work at the Hodgson-Harris reservoir -- located near Superior, Colo. -- includes the restoration of the impounding dam. The rehabilitation project will allow the reservoir to store its historic water volume and also decrease the likelihood of dam failure.
Last, GEI has recently completed a dam inundation project map for Tucker Lake, which is located in Arvada, Colo. The lake is adjacent to Blunn Reservoir and Ralston Creek with impounding dams on its north and south ends. GEI said it performed dam breach analyses and flood inundation for each of the drainage channels, assuming a "worst case" scenario for each dam.
The analyses, conducted for the Arvada's Department of Public Works and Engineering, were performed in accordance with the Colorado Office of the State Engineer's Dam Safety Branch Guidelines for Dam Breach Analysis.
