ASCE/CAGE December Meeting December 14, 2016
Lakewood Country Club
ABSTRACT: The Michigan Ditch is located in Jackson County, Colorado and is part of the City of Fort Collins water supply system and conveys water from the west side of the Never Summer Mountains to Joe Wright Reservoir on the east side of the range. The 5.2-mile-long ditch was constructed in the early 1900's and has been plagued by slope instability since it was built. An area known as the "Mudslide" has experienced accelerated slope instability in recent years and the piped portion of the ditch through the landslide was destroyed in 2015 when the landslide moved over 20 feet horizontally and 7 feet vertically. This presentation will discuss geology and history of the "Mudslide", ongoing efforts to maintain the ditch pipeline through the landslide, design and construction of an eight-foot diameter, 800-foot-long tunnel behind the landslide along with a unique alternative delivery method utilized for evaluation, design, and construction of the tunnel. Presented by:
Robin Dornfest is President of Lithos Engineering, a Colorado based tunnel, trenchless, geotechnical, and geological engi-
neering and design firm. Prior to starting Lithos Engineering, Robin has worked as a mining geologist in California, as a geol-
ogist for the USGS working on projects in the Grand Canyon and San Francisco Bay, and for several geotechnical firms in Colorado. Currently, Robin manages and works on a wide range of project types including: tunnels, shafts, dams, water and
waste water treatment plants, pipelines (water, stormwater, sewer, oil and gas), large public works and capital improvement projects, geologic hazard investigations and mitigation, groundwater control during construction, temporary support of exca-vations, mining projects, and on occasion serves as an expert witness. Robin is a licensed professional geologist in Wyoming, Texas, Nebraska, and Kansas.
Owen Randall, P.E. is the Chief Engineer for the City of Fort Collins Utilities and holds a BSCE from Colorado State Univer-sity. He manages the Engineering Division of the Water Utilities and is responsible for the design and construction of water,
wastewater and stormwater capital projects. His experience includes 39 years involved in the design and construction of wa-ter and water reclamation treatment plants, large diameter water transmission projects, earthen dams, tunnels and large
scale stormwater detention facilities and pipelines. For over 23 years all the projects he has been involved in have been deliv-ered using a project delivery system termed Alternative Product Delivery System that was developed in the City of Fort Collins Utilities. It revolves around a collaborative team approach to design and construction with the engineer and contractor being selected based on qualifications. All design and construction contracts are negotiated. Over 300 million dollars' worth of capi-tal projects have been designed and built using this system.
