10:20 AM	Rehabilitation of a 75-inch Diameter Brick Interceptor in Cleveland	Jordan C. McCormack¸ PE, Wade Trim; Bob Ericsson¸ PE¸ PS, Northeast Ohio Regional Sewer District; and Darby Neidig, Metcalf & Eddy	This paper describes the rehabilitation design process used for an emergency repair project on large diameter brick sewers in Cleveland, Ohio, as well as the alternate solution selection process and risk management analysis used on the project.
10:45 AM	Liner Long-term Performance Life Prediction Using Critical Buckling Strain	Wei (Zack) Zhao, Ultraliner Inc.	This paper proposes a new long-term liner performance life prediction method. The instantaneous buckling equation is used for short-term design¸ and creep and critical buckling strain theory is used to validate the long-term design.
11:10 AM	3D Modeling of Pipe Liners with Local Defects	David Hall, Trenchless Technology Center¸ Louisiana Tech University	This paper investigates the influence of local defects on the liner structural capacity using finite element method. The spacing, magnitude and size of the defect are studied. Design accommodations are discussed based on the research.
Track 2: Water Line Condition Assessment, Session Leader: John Schroeder, CDM
9:30 AM	PCCP Condition Assessment: Exploring Repair Solutions for Wichita Falls 54-inch Transmission Line	Scott Taylor¸ Director of Public Works, City of Wichita Falls, Texas, and Katie McCain, CDM	This paper presents a case study involving the inspection of a waterline in Wichita Falls¸ Texas¸ by Remote Field Eddy Current technology. The paper recommends a rehabilitation program that establishes priorities for repairs based on the failure risk.
9:55 AM	Planning and Executing Internal Inspections of Large Diameter PCCP Waterlines	Arno I. Leskinen, PE, Brown and Caldwell and Brandy A. Kelso PE, City of Phoenix Water Services Department	This paper illustrates the detailed steps involved in planning and performing an internal inspection of a PCCP transmission main¸ using a 40-year old¸ four mile long¸ 66-inch diameter pipeline.
10:20 AM	Assessment of Pressure Pipelines	Dr. Robert A. McKim, Parsons BrInckerhoff; Roy Herwig, Parsons BrInckerhoff; Mike Wooten, Parsons BrInckerhoff; and Richard Thomasson, Parsons BrInckerhoff	This paper reviews the latest technologies and management strategies for pressure pipe assessment that allows assessment of pressure pipes without service disruption.
10:45 AM	Evaluation into the Condition of the Sandhill-Lamb Transmission Main Pipeline	James F. Ciesielski¸ PE, Las Vegas Valley Water District	This paper discusses the evaluation of the condition of Sandhill-Lamb Transmission Main Pipeline, a primary transmission main comprised of 36 in. diameter pipe owned and operated by LVVWD. Investigations revealed only a small section needed to be replaced, resulting in a savings of approximately $2.5 million.
11:10 AM	An Asset Management Strategy for Water Mains	Mike Garaci, Pressure Pipe Inspection Company	This paper discusses how a pipeline operator can develop a rehabilitation plan that is cost-effective and minimizes service disruptions, using a regular inspection program in combination with failure risk analysis and data storage and retrieval from a GIS database.
Track 3: HDD Design Issues, Session Leader: David Bennett, Trenchless Engineers
9:30 AM	Step-by-Step Evaluation of Hydrofracture Risks for HDD Projects	David Bennett, Bennett Trenchless Engineers and Kathryn Wallin, Bennett Trenchless Engineers	This paper presents a step-by-step method for evaluating hydrofracture risks for HDD projects and illustrates the approach using case history data. The approach allows hydrofracture risks to be properly evaluated, using a simple method.
9:55 AM	Determination of Safe Pulling Loads on Fusible PVC During HDD	Samuel T. Ariaratnam, Arizona State University; Tom Marti, Underground Solutions Inc.; and Siggi Finnsson, Digital Control Inc.	This paper describes a method for calculating pull loads on fusible PVC pipe during installations using HDD. The model was calibrated on numerous field projects using in-line measuring devices.
10:20 AM	Soil Reaction to the HDD Process	Brian Dorwart¸ PE¸ PG, Haley & Aldrich¸ Inc.	This paper provides an assessment of the soil reaction to the HDD process, noting that similar soils as desribed in soil logs may not drill with the same performance or even be drillable.
10:45 AM	HDD Construction Risks and Challenges on the King County Bellevue Pump Station Force Main Project	James Chae, Jacobs; Paul Savard, Jacobs; and Shahrzad Namini, King County Wastewater Treatment Division; and Marty Noble, King County Wastewater Treatment Division	This paper discusses the HDD construction risks and challenges for two 32-inch diameter crossings involving the drill and intersect method. The paper addresses drilling under numerous structures¸ settlement monitoring¸ minimal staging area needs and the use of conductor sleeves.
11:10 AM	Alternative Contract Procurement Using HDD Solves Regulatory Dilemma	Clay M. Tappan¸ PE¸ BCEE, CDM; William Gill¸ PE, Pinellas County Engineering Department; Elwood Herom¸ PE, CDM; and Aamod Sonawane¸ PE, CDM	This paper examines the alternative procurement methods of prequalification and piggy-backing used by Pinellas County Utilities to implement a critical HDD project.
Track 4: Large Diameter Tunneling, Session Leader: Dennis Doherty, Jacobs Civil Inc.
9:30 AM	Design Challenges with New York City's Newest Water Tunnel: The Lesser-known Trans-Hudson Crossing	David J. Tanzi¸ PE¸ BCEE, CDM; Paul J. Paparella¸ PE¸ PP, HMM; and James Garin, PE, NYCDEP	This paper discusses the planning¸ design and risk issues associated with the use of a pressurized face TBM for a new sub-aqueous tunnel in New York City.
9:55 AM	Successful Design Selection for Underground Boring Equipment	Dave Long, The Robbins Company and John Kocab, The Robbins Company	This paper presents a road map for the selection of cutterhead geometry and cutting tools in underground boring technology¸ based on geologic conditions.
10:20 AM	Paper To Be Determined
10:45 AM	Guided Boring Method Used to Stabilize 10-foot Diameter Storm Drain Tunnels	Tracy J. Lyman, Lyman Henn¸ Inc..; David A. Kwietnewski, Lyman Henn¸ Inc..; James M. Rose, City of Fort Collins Utilities; and Tanner Randall, Stantec Consulting¸ Inc..	This paper discusses the challenges of installing twin 10-foot diameter storm drainage tunnels through a railroad embankment containing wood trestle elements¸ loose dumped embankment fill and very loose silt at/below groundwater. GBM guide rails were used to stabilize tunnel floor.
11:10 AM	Battery Park Trunk Sewer Emergency Tunnel Project	Mark Rybak, Bradshaw Construction Corp.; Todd Brown, Bradshaw Construction Corp.; and Michael Spero¸ PE, Future Pipe Industries¸ Inc.	This paper discusses the use of emergency fast-track design, bid, build process to line a 144-inch tunnel. The tunnel was severly damaged by a tropical storm that caused extensive flooding in Richmond¸ Virginia and resulted in a sinkhole and collapse of a major sewer.
