Excavations Don’t Have to be Big to Cause BIG Problems
Mike Ross, National Training Director, Efficiency Production Inc.
Many contractors consider the need for safety equipment only when excavating big trenches (10, 20 or even 30 feet in the ground) for laying pipe, manholes or other underground utilities. After all, the OSHA standard mandates a trench protection system for excavations deeper than 5 feet. But not all excavations can be considered large or routine, and it is those smaller trenches and pits that often are the most dangerous. Many workers have been injured or even killed in trenches less than 5 feet deep. This presentation will focus on determining the potential dangers of small or shallow excavations and details of trench protection systems specifically designed, engineered and manufactured for smaller excavations, such as modular shoring systems and “spot shores.” It will also discuss how to match the right trench protection system with specific small excavation conditions.

Benefits of Pipe Slitting for Gas Line Replacement or Decommissioning
Alan Goodman, Ram & Burst National Sales Manager, HammerHead Trenchless Equipment
Pipe slitting is a nonintrusive, safe and often more economical method to replace plastic gas services and mains than exposing them with open-cut techniques. Additionally, pipe slitting of decommissioned gas lines eliminates the cost of extraction without potential to be mistaken for an active line in the future. Runs of up to 400 feet in length are possible in as little as 15 minutes. Project savings are largely due to significantly reduced demolition, trenching and restoration requirements. The pipe-slitting method even permits upsizing an existing line to increase its capacity. This presentation includes a case study of a large gas line installation and maintenance company that uses pipe slitting both for decommissioning inactive lines, and for installing and replacing gas line infrastructure.

Guided Boring Application: Pairing the Right Tooling With the Challenge
Shawn Gaunt, Operations Manager, Kamploops Augering & Boring Ltd.
Chris Sivesind, Sales Engineer, Akkerman
Guided boring systems have been empowering contractors to achieve accurate and extended drives in various ground conditions for nearly 15 years. Over the past decade, guided auger boring has become a popular method to accurately install up to 72” steel casing to ensure bore accuracy, expedite installations, avert downtime and realize project savings. Recent innovations have made it possible to use a standard guided boring system to install pilot tubes in rock density up to 10,000 psi and up to 36” steel casing with a standalone frame equipped with enough torque to rival a traditional auger bore machine. This presentation is appropriate for all audiences interested in recent pilot tube case studies where the solution surmounted project adversity.

His career in trenchless construction, shoring and equipment sales has spanned over two decades, and he is an active presenter and participant at industry conferences and initiatives promoting trenchless technology. He received his formal education from Washington State University.

72” Motorized SBU on Multiple Bores with Strict Line, Grade
Keith Mayfield, Project Manager, Strack Inc.
Joe Lechner, TBM & SBU Sales, The Robbins Company
Today’s contractors require versatility and accuracy, particularly when constructing water mains and gravity sewers. An articulated, steerable auger boring attachment can achieve strict line and grade tolerances in a variety of ground conditions, as evidenced by a recent project in Cobb County, GA.  A 72” auger boring attachment, known as a Motorized Small Boring Unit (SBU-M), was used in conjunction with an ABM to bore a series of crossings below creeks and busy interstate highways in both hard rock and mixed ground. In each case, the crossing was completed within inches of specified tolerances, and well within the line and grade limits specified by the contract. This presentation will discuss the unique requirements of the project, the boring setup, and methods used to achieve excellent results. Perspectives will be given by both the contractor and the equipment supplier.

New Approaches to Utility Cut Pavement Repair
Marshall Pollock, President and CEO, Utilicor Technologies Inc.
Dennis Jarnecke, Gas Technology Institute

This presentation elaborates on Keyhole Coring and Reinstatement, one of the best practices identified by the FHWA-commissioned research and development project, “New Approaches to Utility Cut Pavement Repair.” Keyhole technology enables utility crews to safely and cost-effectively conduct main replacement activities, locate underground infrastructure, and perform repair or maintenance work from the road surface through 18″- or 24″-diameter, circular ‘keyholes’ cored through the pavement. The reinstated pavement cores result in a permanent, almost invisible, waterproof pavement repair that can maintain the performance life of asphalt and concrete pavements; and avoid costlier, more disruptive and more dangerous excavation methods. It is also an environmentally friendly process that eliminates the need for new paving materials and the disposal of old, by reusing the original materials to restore the roadway after the excavation.

marshall-pollockMarshall Pollock, an attorney, is president and CEO of Utilicor Technologies, leading the technical development of this manufacturer and distributor of the industry-leading keyhole pavement coring and reinstatement system. He holds advanced degrees in science and law and a degree in Naval Engineering and Design from the Annapolis Naval Academy. He is a frequent participant in international conferences and the author of numerous articles related to keyhole and trenchless technology, damage prevention and utility construction and maintenance.
