ITI Researchers Present Advances in
Geotechnical Instrumentation

ITI researcher Professor Richard Finno presents his invited theme lecture, “Use of Remote, Real-Time Monitoring Data for Supported Excavations” at FMGM.

ITI-sponsored research was prominently featured in the program of the 7th International Symposium on Field Measurements in Geomechanics (FMGM), a technical conference presented by the Geo-Institute of the American Society of Civil Engineers (ASCE). The symposium was held September 24-27, 2007, in Boston, Massachusetts. ITI researchers contributed six technical papers, authored by Professors Charles Dowding and Richard Finno and research engineers David Kosnik and Mathew Kotowsky. Professor Finno presented an invited theme lecture and Professor Dowding served as vice chair of the conference organizing committee.

Professor Finno’s invited theme lecture, “Use of Remote, Real-Time Monitoring Data for Supported Excavations,” summarized advances in the theory and practice of design and performance evaluation of supported excavations. The technique, called “inverse analysis,” uses intelligent updating with real-time data to improve the ability of numerical models to predict soil deformation around an excavation. Improved performance models will help anticipate and prevent disruptions to transportation infrastructure facilities, such as roads, railroads, and pipelines, due to nearby excavations. Finno also presented a technical paper, “Real Time Monitoring at the Olive 8 Excavation,” which described the use of an automated survey instrument to measure the performance of a deep excavation with an unusual support system.

Professor Dowding presented “Response of Historic Structure to Long-term Environmental and Construction Vibration Effects” and “Multi-Hop Wireless Crack Measurement for Control of Construction Vibrations.” These respectively described wired and wireless approaches to quantifying the effect of construction vibrations on adjacent structures.

ITI research engineer David Kosnik presented “Internet-Enabled Geotechnical Data Exchange” and “Case Studies in Integrated Autonomous Remote Monitoring,” which described ITI’s techniques and experience in data acquisition, communication, and autonomous data archiving and display over a wide range of infrastructure instrumentation projects. Mr. Kosnik emphasized the importance of robust communication systems and the value of autonomous Internet-enabled data display techniques, such as those developed at ITI.

When not presenting papers or attending sessions, ITI research engineers David Kosnik, Mathew Kotowsky, and Daniel Hogan staffed an information booth in the exhibit area, showcasing ITI’s work and soliciting new external deployment partners for ITI research.
