In 2017, NHI will release upgraded training courses 132034 on ground modification methods and 132085 on soil nail walls. SHRP2 Implementation continues into its final year. Final program initiatives include developing and delivering training modules on calibration at the service limit state and designing structures considering the effect of deformation; and continuing to deliver training and technical assistance through GeoTechTools and updating the system to incorporate case histories, photos and video from successful ground modification jobs around the country. Updated FHWA Deep Foundations Load Test Database: The FHWA Office of Infrastructure Research and Development (HRDI) announced the release and availability of the updated FHWA Deep Foundation Load Test Database (DFLTD v.2), which can be downloaded at https://www.fhwa.dot.gov/software/research/ infrastructure/structures/bridges/dfltd/index.cfm. Instructions on how to install and use the DFLTD are provided in the associated User Manual (FHWA-HRT-17-034), which can be downloaded at https://www.fhwa.dot.gov/ publications/research/infrastructure/structures/bridge/dfltd/index.cfm. DFLTD v.2 contains more than 1,600 research quality load tests on various types of piles and drilled shafts. The records in the database can be queried in numerous ways, including foundation type and size, subsurface soil information, and location. The functionalities included in the software will help facilitate best practice and greater reliability in the design and construction of different deep foundation elements. DFLTD v.2 can be used by federal and state agencies, universities, consultants and contractors, design engineers and planners, and research and development professionals. Allen Cadden, P.E., Schnabel Engineering, and Bradley Keelor, ASCE/Geo-Institute executive director, led a workshop at the TRB conference on DIGGS (Data Interchange for Geotechnical and Geoenvironmental Specialists). The workshop was aimed at soliciting industry feedback on the DIGGS system, which was developed to become an industry- standard protocol for transmitting and storing geotechnical and geoenvironmental information serving a wide range of public-sector institutions and private-sector industry organizations. In January 2017, Cadden and Keelor released a report entitled Implementation and Transition of Data Interchange for Geotechnical and Geoenvironmental Specialists (DIGGS v2.0), which outlines the XML-based system developed under a FHWA State Pooled Funding Study led by the Ohio Department of Transportation (ODOT) from 2005 to 2012. The system is designed to store data in a standardized, open and consistent format. That data can then be readily imported, managed and analyzed by stakeholders for preparing geotechnical boring logs, laboratory test summaries, performance monitoring instrumentation reports, and in-situ testing profiles and reports. The DIGGS report may be downloaded at http://diggsml.org/publications/diggs-implementation-and-transition. SOA and SOP in Assessment of Earthquake-Induced Soil Liquefaction: The National Academies of Sciences, Engineering and Medicine (NASEM) released its report State of the Art and Practice in the Assessment of Earthquake-Induced Soil Liquefaction and Its Consequences in December 2016. A pre-publication version of the report is available for download at https://www.nap.edu/catalog/23474/state-of-the-art-and-practice-in- the-assessment-of-earthquake-induced-soil-liquefaction-and-its-consequences. This study was conducted under the auspices of the NASEM’s Committee on Geological and Geotechnical Engineering (COGGE) and sponsored by the Bureau of Reclamation, U.S. Nuclear Regulatory Commission, Federal Highways Administration, American Society of Civil Engineers/Geo-Institute, Port of Los Angeles, Port of Long Beach, and the Los Angeles Department of Water and Power. NASEM conducted several briefings on the report, including a session at the Geotechnical Frontiers Conference in Orlando, Fla., March 12- 15, 2017.
