To be sure DFI members have access to the broadest and most current information, knowledge and events, we have formed alliances with several organizations.

ADSC: The International Association of Foundation Drilling
The International Association of Foundation Drilling (ADSC), is a professional, international association. The membership represents those who work in the foundation drilling industry and related heavy civil construction/design industries, and includes companies that perform work as specialty subcontractors, manufacturers, suppliers, academicians and engineers in both the private and public sector.

CGS: The Canadian Geotechnical Society
The Canadian Geotechnical Society is the premier organization for geotechnical engineers and geoscientists in Canada and is dedicated to advancing knowledge and creating opportunities for the sharing of information by practitioners in a broad range of geotechnical disciplines.

Deep Mixing Conference Series
A consortium of practitioners have organized and presented conferences on deep mixing, which have provided significant technical contributions to the advancement of the understanding, use and performance of deep mixing internationally. The organizers are loosely held, dedicated group of international representatives dedicated to providing a forum for discussion and progress in the deep mixing industry. The conferences contain a wealth of knowledge and archive the evolution of the understanding of material properties, new technologies, research, mix designs, and quality control and assurance for wet and dry deep mixing methods.

Geo-Coalition creates a sense of Geo-community through the encouragement of communication, cooperation and collaboration among its members as products and events are publicized and promoted. The group identifies opportunities for members to endorse common positions and provide a powerful common voice to influence the geo-future.

Geo-Industry CPT Users Group
This joint industry group was created in cooperation with FHWA, GeoInstitute, DOTs, DFI and TRB Committee AKG20 to address CPT users' needs. Anyone interested in cone penetration testing is welcome to join. Regular monthly virtual meetings are held using MS Teams on the last Tuesday of the month 3:00 p.m. (ET). Please contact the chair for joining instructions. Teams will also be used to house information generated by the group, and links will be provided on this webpage for access.

Geo-Industry Risk Working Group
The geo-associations, including ADSC, DFI, Geo-Institute, Geotechnical Business Association, and PDCA, all provide risk-related activities and resources for the industry (guidance documents, seminars, white papers, etc.) While each group continues to pursue their own activities independently, the groups are also collaborating in this industry-wide group on risk to increase awareness of associations' activities, reduce duplication of efforts, facilitate collaboration, and address risk practices that can be agreed will improve the industry.

The Geo-Institute (G-I) is a specialty membership organization focused on geo-professionals and the geo-industry. It is one of the American Society of Civil Engineers' eight specialty Institutes. In recognition of our common and complementary purpose and shared interests, DFI and G-I have agreed to formalize their relationship in advancing their mutual interests in the continual improvement of the planning, design and construction of deep foundations and excavations through presentation of technical topics within the geo-technical profession through a Memorandum Of Understanding (MOU).

ISM: The International Society for Micropiles
The International Society for Micropiles (ISM) is a consortium of international representatives involved in the design, construction, research/development and instruction/promotion of micropile technology.

PDCA: Pile Driving Contractors Association
The Pile Driving Contractors Association (PDCA) is an organization of pile driving contractors that advocates the increased use of driven piles for deep foundations and earth retention systems.

U.S. Army Corps of Engineers
U.S. Army Corps of Engineers (USACE) and Deep Foundations Institute (DFI) established a partnering relationship to address mutual participation in the Nation's dam and levee safety programs. The common goal is to enhance the safety of dams, levees and coastal area construction and rehabilitation projects to improve quality and safety while lowering project risk and cost.

U.S. Levee Safety Coalition
The United States Levee Safety Coalition (Coalition) is a group of professional organizations joined to support and advance levee safety in the U.S. The mission of the Coalition is the advancement of levee safety across the country through good engineering practices, sound public policy and increased awareness and education within communities of practice and the public.

The original members of the Coalition are the American Society of Civil Engineers (ASCE), the Association of State Dam Safety Officials (ASDSO), the Deep Foundations Institute (DFI), the National Association of Flood and Stormwater Management Agencies (NAFSMA), the United States Society on Dams (USSD), and the American Council of Engineering Companies (ACEC).

USUCGER: United States Universities Council on Geotechnical Education and Research
The United States Universities Council on Geotechnical Education and Research (USUCGER) was founded in 1985 to provide advocacy for the continued development and expansion of high quality geotechnical engineering research and education by US academic institutions. This discipline has evolved to include geotechnical, geomechanical, geoenvironmental, geological, and geophysical engineering.

Working Platforms Industry-Wide Working Group
The Working Platforms Industry-Wide Working Group (WPWG) is an industry-wide forum gathered to improve design and construction practices that ensure safe working platforms for equipment used to install deep foundations.
