Roller Compacted Concrete Dams and Spillways
International Technical Seminar and Study Tour
May 6-13, 2013
(Denver, Colorado and California)
Introduction/Seminar Objectives - The use of RCC in the construction of dams and spillways has become increasingly widespread. RCC techniques are popular for safety of dams modifications, including buttressing concrete dams, rehabilitation of spillways, and overtopping of embankment dams. RCC construction techniques combine the safety, aesthetic, and maintenance advantages of concrete dams with the low cost and high production rates normally associated with earth or rockfill embankment dams. Through lectures, discussions, hands-on laboratory testing, and site visits, led by RCC experts, participants will receive practical training and gain an excellent understanding of the advances in RCC materials, mixtures, and construction operations that facilitate the rapid production rates of RCC dams and spillways.Who Should Attend - The seminar is designed for officials responsible for policy making, planning and management of dam projects. In addition, engineers and technical staff with design construction responsibilities should attend. All presentations, discussions, and printed materials will be in the English language. Participants should have a good command of general and technical English usage.
Seminar Topics - The first week, May 6-10, 2013, will take place in Denver, Colorado, and will consist primarily of classroom and laboratory presentations and discussions. Lectures, case histories, structured discussions, and hands-on testing covering materials, mixtures, and construction of RCC dams and spillways will be led by technical experts from Reclamation and others involved in current, state-of-the-art RCC techniques.Topics:
• State of the Practices of RCC Dams
• RCC Material and Concrete Laboratory Testing
• RCC Production, Transportation and Placement
• Case Histories
Study Tour - From May 10-13, 2013, participants will visit local sites in Colorado and sites in California including:Olivenhain Dam and Reservoir, the first roller compacted concrete dam built in California, at 97 meters high, the dam was designed to both withstand and remain fully functional during and after an earthquake, to keep water flowing into the region. The dam is the cornerstone of the San Diego County Water Authority’s (SDCWA) Emergency Storage Project, a system of reservoirs, interconnected pipelines, and pumping stations designed to make water available to the San Diego region in the event of an interruption in imported water deliveries. The dam is currently the highest RCC dam in the United States though it will soon be surpassed by the SDCWA modified San Vicente Dam scheduled for completion in 2012.
San Vicente Dam, owned and operated by the City of San Diego, currently stands at 67 meters high. The SDCWA will raise the dam an additional 35.6 meters – the tallest dam raise in the United States and the tallest of its type in the world. The raised dam will store roughly an additional 188,000,000 cubic meters of water, more than doubling the reservoir’s water storage. The downstream side of the existing dam will be completely covered by roller-compacted concrete and will be built to remain operational in the event of a major earthquake. Preparatory work is underway with expected completion in 2013.
