Jamey Rosen to Present on Project Information Management Systems at DFI's Annual Conference on Deep Foundations

Jamey Rosen, P.Geo (Ontario, Canada) will virtually present "Analysis of Panel and Pile Verticality and Overlap in a PIMS" at 4:50 p.m. on October 14, 2021; and Terry Holman, Ph.D., P.E. (Illinois) will virtually lead a meeting of the DFI Working Platforms Working Group at DFI's 46th Annual Conference on Deep Foundations at the MGM Grand in Las Vegas, Nevada.

Geosyntec's Matthew Chartier, P.E. (Massachusetts) will also be attending the Deep Foundations Institute's 46th Annual Conference Matthew Chartier, P.E. (Massachusetts).

Jamey Rosen is a Senior Principal Geoscientist based in Ontario with more than 20 years of experience focused on Geospatial Information Management System design and development. Jamey has built systems to validate, manage, analyze, and visualize construction, geotechnical, and environmental data for projects and facilities in the United States and Canada. Jamey is the chairman of the Project Information Management Systems Committee.

Terry Holman is a Senior Principal Engineer with more than 25 years of professional experience focused on the areas of: geotechnical and geostructural engineering; design; construction management; specialty geotechnical construction; heavy-civil construction; and environmental heavy demolition. Terry leads Geosyntec's Geostructural and Construction Engineering initiative. Terry is the chairman of the ADSC-DFI-PDCA Working Platforms Working Group.

The theme of the DFI conference is "Winning Practices & Ace Technology." The conference will discuss how to improve the odds of generating high-value foundation solutions when the house is the ever-changing challenges of variable ground conditions, extreme events, and demanding project constraints. Papers and panel discussions will be presented to explore and debate challenging geotechnical and foundation topics, including challenging and unanticipated soil conditions, natural hazards and resiliency, seismic design and construction techniques, risk mitigation and sustainability practices, innovative case histories, and new methods and equipment. The conference will highlight how the geotechnical and foundation industry increases the odds of high-value, high-quality projects using innovations, advancements, expertise, and experience.

As an international membership association, Deep Foundations Institute, incorporated in 1976, gathers worldwide geotechnical professionals involved in the design and construction of deep foundations and excavations. The DFI community is comprised of project owners, general and specialty contractors, engineers, manufacturers, suppliers, educators, and students. This multidisciplinary membership creates a consensus voice and a common vision for continual improvement in the planning, design, and construction of projects with complex geotechnical conditions. Their 4,000+ worldwide members are provided a forum for networking, education, communication, and collaboration. Through their combined expertise, they promote the advancement of the deep foundations industry through technical committee activities, educational programs, and conferences, publication of guides and specifications, a peer-reviewed journal, a flagship magazine, funded research, government relations, and outreach.


Verticality data collected from panel and pile elements of seepage barrier walls describe the shape and position of those elements in three dimensions. These data are used to determine if a barrier wall is constructed as designed and if it meets the owner specifications with respect to tolerance (i.e., if each element is sufficiently close to vertical) and overlap (i.e., do adjacent elements overlap sufficiently to prevent leakage). Contractors use verticality data to confirm that their work matches their design, and owners use verticality data to verify the contractor's work and confirm that specified criteria were met. Project Information Management Systems (PIMS) technology has been applied to the management, visualization, and analysis of verticality data. This paper will provide examples of how contractors and owners have used a PIMS to compile and synthesize data collected during excavations (e.g., from Cutter Soil Mixer and Hydromill drill rig telemetry), and from measurements of completed excavations (e.g., using the Koden ultrasonic tool), and used those data to model excavation geometry. We will present case studies of using these models to estimate slurry placement volumes, and "cutting" the models at depths to evaluate the verticality tolerance and overlap between elements.
