This effort is being led by Ted Maynard, ASCE/GI liaison. Maynard is a geotechnical engineer and a retired Chicago Building Official. Proposed revisions will be submitted to ICC early January 2015 with oral presentations to ICC Structural Code Committee in Dallas in May 2015. While our committee’s 2014 research proposal will not be funded by DFI, we appreciate the initiative shown by our members, and encourage the continued submittal of issues that affect our industry COMMITTEE CHAIR TOM GURTOWSKI Codes and Standards Committee The Codes and Standards Committee continues to lead an industry- wide effort under the umbrella of GeoCoalition Codes Committee to review and prepare proposals revising the 2015 International Building Code (IBC) Chapter 18 “Soils and Foundations.” Committee members are collaborating with representatives from the Pile Driving Contractors Association (PDCA), GeoInstitute of the American Society of Civil Engineers (ASCE/GI), ASFE: The GeoProfessional Business Association, other DFI Technical Committees and ADSC: The International Association for Foundation Drilling to provide consensus proposed changes to the building code. The geotechnical community, contractors and designers are currently working together to affect change that reflects the expertise and knowledge of geoprofessionals. The group is focused on the following sections of Chapter 18: 1803 Geotechnical Investigations (ASFE, ASCE/GI, DFI) 1804 Excavation, Grading and Fill (ASCE/GI, ASFE, DFI) 1806 Presumptive Load-Bearing Values of Soils (DFI, ASCE/GI, ASFE) 1807 Foundation Walls, Retaining Walls and Embedded Posts and Poles (DFI, ASCE/GI, ASFE). Scott DiFiore of Simpson Gumpertz & Heger is leading the revisions to Section 1807. DiFiore is also active in reviewing the Massachusetts Building Code, and his team is including some guidelines regarding MSE wall design. 1808 Foundations (DFI, ASCE/GI, ASFE, ADSC) Expansive and Collapsible Soils (ASCE/GI, ASFE) 1810 Deep Foundations (PDCA, DFI, ASCE/GI, ADSC, ASFE) Dale Biggers of Boh Brothers Construction is coleading the review of Section 1810. The first round of comments has been completed, and the group is currently writing basis statements for various proposals. as well as research designed to improve deep foundations. Also, I would like to welcome, belatedly, Vaughn Godet, Berkel & Company Contractors, as vice chair of the committee.
