Late registrations will be accepted, but a $10 late fee ($5 for students) will be assessed for any reservation made after Friday. Cancellations within 7 days of the event will incur a fee equal to the registration fee.
The Deep Underground Neutrino Experiment (DUNE) will be the first internationally conceived, constructed, and operated mega-science project hosted by the Department of Energy in the United States. The project will advance the understanding of neutrino science The Long Baseline Neutrino Facility (LBNF) Far Site Conventional Facilities are essential infrastructure for the project. They are sited at the Sanford Underground Research Facility (SURF) located within the former Homestake Gold Mine in Lead, South Dakota. The project involves excavation and support of three large caverns which will house four 10 kT fiducial volume liquid argon (LAr) neutrino detectors and cryogenic equipment, as well as numerous ancillary connecting drifts and chambers.
This presentation will provide an overview of the project, the geological setting, the geotechnical investigation undertaken nearly a mile underground and the challenges associated with collection of reliable data in a high stress and geologically complex environment. The layout for the new facility will be presented, along with a description of some of the constraints that will impact construction methods and sequencing, including shaft access and working within an operating research facility. It will also describe an underground test blast program undertaken to develop site-specific vibration and overpressure attenuation data for design of production blasting, bulkheads, and laboratory protection measures.
Mark Havekost is a Principal with McMillen Jacobs Associates and works out of the Portland office. He has 24 years of experience as a civil engineer working on a broad range of geological, geotechnical, and civil engineering projects for hydropower, transportation, and water/wastewater conveyance projects. He is focus has been on evaluation, design and construction of tunnels, shafts, and other underground structures. Mr. Havekost earned a M.S. in Geotechnical Engineering from University of California, Berkeley and has a B.S. in Civil Engineering from California Polytechnic State University.
Joshua Yacknowitz is a Principal with Arup, and leads Arup's Seattle office. He has 28 years of experience as a mechanical engineer, working for both manufacturing companies and as a consultant. His focus with Arup over the past 15 years has been in science and industrial facility design and consulting, leading large multi-disciplinary teams of architects, engineers and technical specialists. Mr. Yacknowitz is also Arup's Science & Industry business leader in the Americas. Mr. Yacknowitz has a BE in Mechanical Engineering from the City University of New York, and is a licensed Professional Engineer in multiple states.
