Richards, P.E., D.GE, Nicholson Construction, [email protected] • AASHTO Soil Nail construction specification and design specification are being approved. • Committee continues to work towards hollow bar consensus. • Anchor Bar Epoxy Coating study is complete and draft paper is in review. • Anchor tendon metal creep for larger bar sizes is underway. • Conducting a study on Developing Guidance for Factoring Structural Resistance for Landslide Stabilization and Excavation Support. • Supporting DFI S3: Slopes, Slides and Stabilization Conference, August 4-6, 2020, San Francisco, and seeking software problem (case study) and presentations. Augered Cast-in-Place Pile and Drilled Displacement Pile Chair: Jonathan Huff, P.E., Richard Goettle, [email protected] Trustee Liaison: W. Morgan NeSmith, Jr., P.E., Berkel and Company Contractors, [email protected] • Developing a white paper on building code provisions for use of a single large diameter (24 to 48 in or 610 to 1220 mm) element under building columns, rather than a group of ACIP piles within a cap. • Additional work is being performed on data acquisition for research on TIP testing of ACIP piles. Gray Mullins, Ph.D., of University of South Florida is analyzing the data and will be generating a research paper. DFI Europe BIM/Digitalisation • Progressing on helping develop AASHTO specifications for ACIP pile design. Chair: Jason Boddy, C.Eng, MICE, Arup, [email protected] Trustee Liaison: Gianfranco Di Cicco, Bauer Foundation Corp., [email protected] • Committee is growing with representatives from 11 countries. • Continuing to develop a practical guidance document for Digitalisation in Ground Engineering. • Collaborating in the U.K. with the Federation of Piling Specialists (FPS) and Association of Geotechnical and Geo- environmentalists (AGG) on open standard for pile construc- tion data, which is currently being circulated for comment. The standard will be presented at the U.K. Piling 2020 Conference and is also being circulated more widely across Europe for collaboration with other European initiatives. 62 • DEEP FOUNDATIONS • JAN/FEB 2020 Gianfranco Di Cicco Daniel Stevenson Lori Simpson • Planning a seminar in fall 2020 with industry leaders to dis- cuss challenges and solutions to adopting digitalisation and BIM. • Liaising with DFI Project Information Management Systems (PIMS) Committee in U.S. Codes and Standards Chair: Dan Stevenson, P.E., Berkel and Company Contractors, [email protected] Trustee Liaison: Lori Simpson, P.E., G.E., Langan Engineering and Environmental Services, [email protected] • As a participating member of the GeoCoalition Code Council, the committee completed participation in the ICC 2021 code cycle to upgrade and improve Chapter 18 of the International Building Code. The GeoCoalition submitted 17 code change proposals, all of which were approved at the ICC Committee Action Hearings in Albuquerque, New Mexico. • Continuing collaboration with ASTM Subcommittee D18.11 to promote proposed changes to ASTM D1143. • Continuing to collaborate with American Concrete Institute (ACI) regarding requirements for the design of concrete deep foundations members, which are now included in ACI 318-19. • Monitoring and participating in the development of a proposed new ASCE standard for foundation design. • Developing an agenda of potential code change proposals for the upcoming 2024 ICC code cycle.
