2018 Conference Speaker & Presentation Information
Geosyntec Consultants, Inc. and Georgia Institute of Technology
This presentation will briefly review several waste fill stability failures from the time-frame of the early 1980s to mid 1990s and the lessons learned during that period. Notwithstanding the lessons learned, waste fill failures continue to occur. Several from the current decade are reviewed and it is concluded that 20 to 30 years after the earlier time-frame, facility owners and the geotechnical practitioners designing those facilities are re-learning the earlier lessons, while at the same time there are new lessons to learn related to evolving waste streams and operating practices at many U.S. facilities.
- Recognize that the potential modes of geotechnical instability of waste fills.
- Understand the factors that led to several notable historical waste fill failures and the lessons learned.
- Recognize that new factors are contributing to waste fill failures in the current decade.

Developments in the design of deep supported excavations have been driven by field observations collected during construction of such systems. The lecture illustrates this by presenting a number of aspects of design related to both limit state and serviceability. Field performance data are discussed relating to lateral loading diagrams for internally braced excavations, stiffness based design based on allowable deformations and current capabilities with respect to prediction of ground deformations both during the design stage and as construction proceeds. This “adaptive management” approach is an extension of the classical observational approach long advocated by Prof. Peck.
- Understand how field observations formed the basis of design of excavation support
- Understand the different approaches for limit and serviceability based design of excavation support
- Understand the observational approach entails more than observations

In May 2018, a team of geoprofessionals went on an ASCE G-I-sponsored trip to China, to observe ground improvement technologies commonly used in that country. Team members on the so-called ASCE China Scan Tour consisted of practitioners and academicians from the United States and Canada. The team visited six job sites and observed the application of a wide range of ground improvement technologies, including diaphragm walls, recoverable/reusable anchors, soil mixing, different types of vacuum consolidation, and electro-osmosis. The trip culminated with the 2nd China-U.S. Workshop on Ground Improvement that was jointly organized with the Chinese Institution of Sol Mechanics & Geotechnical Engineering and held on May 27 in connection with the GeoShanghai International Conference. The team has completed a report that will be made available by the Geo-Institute soon. This presentation will provide a summary of the China scan tour on ground improvement technologies.

This paper observes how acquisition and storing drilling data has gone long ways from collecting it with pen and paper and archiving it into carton boxes back in the day, to collecting it or transforming it into electronic form and storing it into the cloud these days. We look why this happened, what enabled it, and how this shaped a contemporary subsurface data flow from raw data to data represented geospatially, to interpreted data turned into information, to interpolated data turned into 3D models that are used in collaborative environments and Building Information Modeling (BIM).
- How to manage down-to-earth data up in the cloud
- How to geotechnical engineers can share their information in real-time, in a collaborative environment with other engineering disciplines
- Understanding Geotechnical Building Information Modeling (BIM)

University of California, Berkeley
Recent advances in sensor systems offer intriguing possibilities to radically alter methods of condition assessment and monitoring of geotechnical infrastructure. In this talk, it is hypothesized that the future of geotechnical infrastructure relies on smarter information; the rich information obtained from sensors within infrastructure will act as a catalyst for new design, construction, operation and maintenance processes. Some examples of emerging sensor technologies for infrastructure sensing are given. They include distributed fiber-optics sensors, computer vision, wireless sensor networks, low-power micro-electromechanical systems, energy harvesting and citizens as sensors.
- Learning new emerging sensor technologies
- Seeing how new technologies are used in geotechnical engineering practice
- Examining the value of sensing in geotechnical engineering

DDS Engineering, PLLC
In the early morning hours of 12 February 2014, the National Corvette Museum (NCM) and the Bowling Green, Kentucky community were awakened to the realization that Mother Nature is still in control. Who would have ever expected that a sinkhole large enough to swallow 8 Corvettes would open anywhere in the world, much less inside the iconic Frustum at the National Corvette Museum?
This presentation will highlight key points from that early morning to the conclusion of the first phase of stabilization and remediation of the project site.
- The importance of a thorough initial geotechnical investigation of a proposed site.
- The possible catastrophic failure that can occur even when a ‘thorough’ geotechnical investigation is conducted.
- Methods to address the remediation of a catastrophic sinkhole collapse.

Besides the fire department, Dennis was one of the first to respond to the NCM that fateful day.
Vice President – Hayward Baker Rocky Mountain region
K-7 Mine Remediation
The proposed KDOT widening of K-7 extended above existing mine voids from the abandoned coal seems which varied from 18'-50' below existing ground surface. Portions of the alignment had experienced sinkhole activities previously and some pressure grouting had been performed previously with some success. Specialty grouting equipment and project team collaboration allowed for the project to be completed on time and on budget.
- Geotechnical investigations of abandoned mine workings can often identify collapsed mine rubble or sediments as open voids. Down hole camera inspection of apparent voids during geotechnical program can greatly benefit the geotech data for use in planning the grouting protocol.
- Development of a clear grouting protocol with acceptance criteria is critical to project effectiveness and efficiency. The "lets wait and see how the first hole goes approach" to acceptance criteria leads to confusion and inefficiency in the field. Development of a joint grouting protocol with owners engineers and contractors grouting staff can greatly benefit the project.
- Video monitoring of grouting is a great visual aid when in large mine openings but should be used a as supplemental grout verification after well established grouting protocol.
