Simpson worked with other industry leaders representing DFI, ASCE, Geo- Institute, Pile Driving Contractors Associ- ation (PDCA), International Association of Foundation Drilling (ADSC) and Geopro- fessional Business Association (GBA). This group worked diligently to develop and propose extensive foundations-related code changes for consideration for the 2018 International Building Code. Subcommittees met weekly or monthly for almost two years to review the existing code language, discuss potential modifications, write new code language, and write justifications for the changes. Simpson led the efforts of the Codes and Standards Committee who met monthly to review the proposed changes. Gary Seider, P.E., of Hubbell Power Systems|Chance, chair of the DFI Helical Piles and Tiebacks Committee, was recognized for his role in leading this active and productive group. The committee has been very successful on the following projects during the past several years: • Developing a state-of-practice study on helical piles, funded through the DFI Committee Project Fund (researchers: Profs. Alan Lutenegger, P.E., of the University of Massachusetts and Sam Clemence of Syracuse University). • Publishing standard specifications for helical anchors and compression piles, available for download at www.dfi.org. • Developing standard specifications for helical soil nails. • Developing a helical pile design guide. • Developing a committee-endorsed engineering instruction/training program for helical designers. • Preparing and delivering annual topical seminars. • Conducting an industry-funded helical seismic research study including literature review, laboratory and model testing, and full-scale field testing (researcher: Prof. Amy Cerato, P.E.. of the University of Oklahoma). • Working on two draft ASTM Standards: (a) helical pile testing and (b) installation and testing. Victor Donald, P.E., of Terracon, chair of the Subsurface Characterization for Deep Foundations Committee, received the President’s Award for his contribution to the revisions to the American Institute of Architects (AIA) document C202-2015, Standard Form of Consultant’s Services: Geotechnical Engineering Services. These revisions focused on contesting the low bid process for selecting geotechnical engi- neers, negotiating scopes of investigation work, and encouraging the involvement of geotechnical engineers in the specification review and throughout construction. The key goals of the changes to this standard included a qualitative selection process and encouraging better collaboration. The original documents favored selection based on standardized criteria, with low cost highlighted as the differentiating factor. The new contract language suggests selection be based on the criteria defined as most important by the owner, thereby eliminating an inherent selection bias. Such a selection process is similar to how other professional services (e.g., architec- tural services) are procured. AIA represen- tatives were receptive to DFI input regarding modifying the provisions relating to coordination and collaboration on owner project information, detailed plans for field explorations, and ongoing consultation with the construction team on technical recommendations. The new contract language can be obtained from www.aia.org/contractdocs/reference. Bob Simpson, P.E., of Loadtest and member of the Testing and Evaluation Committee was recognized for his countless hours of work to develop a detailed script and imagery for a video outlining static load testing. This video is the first in what is hoped to be a series of DFI videos on testing and evaluation. The video is intended to provide nonpracti- tioners a better understanding of this foundation testing method. Simpson developed all of the text for the script and waded through numerous photographs to present the concepts of planning and executing an effective foundation load test contained in this 24-minute video, avai lable at ht tp: / /www.df i .org/ StaticLoadTesting.
