DFI Technical Committees
Technical Committees are the backbone of DFI. It is their role to focus on the unique issues of major methods and technologies within deep foundations and excavation. Committees are added as new methods and technologies are introduced in the deep foundations industry. The DFI Committee Project Fund was created in 2011 to provide funding of Technical Committee projects that advance the state of practice and understanding of deep foundations and provide a usable deliverable. As a DFI member you can participate in one of several Technical Committees.
- Augered Cast-In-Place Pile
This committee comprises a roster of industry-wide professionals involved in the design, understanding, advancement and use of augered cast-in-place (ACIP) and drilled displacement pile foundation systems.
- Codes and Standards
This committee concentrates on codes issues that affect deep foundations practices. The committee monitors proposed code changes, forms alliances with other geotechnical societies and structural engineering groups and attends public hearings to express DFI's opinions. The committee proposes code changes developed by DFI technical committees and works toward having DFI technical guidance accepted by code writing bodies.
- Deep Foundations for Landslides/Slope Stabilization
The focus of this committee is deep foundation-related (non-earthwork) technologies for stabilization of landslides and slopes. This practice area involves various foundation techniques developed and constructed by DFI members.
- Drilled Shaft
A committee of industry-wide professionals involved in the understanding, design, construction, and advancement of drilled shaft foundation systems. This committee often collaborates with ADSC's Drilled Shaft Committee.
- Driven Pile
This committee comprises a roster of industry-wide professionals involved in the understanding, design, construction, analysis, and advancement of driven pile foundation systems.
- Electric Power Systems Foundations
This industry-wide committee/discussion forum was created to address issues related to deep foundation design and construction in the electric power systems industry.
- Energy Foundations
The Energy Foundations Committee focuses on advancing the understanding and use of deep foundations as geothermal heat transfer elements.
- Ground Improvement
The Ground Improvement Committee addresses technologies for foundation improvement and liquefaction mitigation. The technologies include but are not limited to vibratory stone columns, vibrocompaction, vibro concrete columns, aggregate piers, dynamic compaction, wick drains and grouted inclusions.
- Helical Piles and Tiebacks
This committee includes manufacturers, engineers, academics, suppliers and experienced contractors which constitute a forum for advancing the applications, understanding and use of helical pile and tieback foundation elements.
- Manufacturers, Suppliers and Service Providers
The goal of this committee is to maximize the value of member benefits for DFI's manufacturer, supplier and service provider members by providing opportunities to increase networking and technical activities. Through these enhanced opportunities, these deep foundations industry innovators will add increasing value back to the entire organization and the industry at-large. The committee is currently establishing their mission statement, purpose and goals.
- Marine Foundations
A committee of industry-wide professionals who promote and support the design, construction and equipment supply for marine foundation projects such as wharfs, bridges, locks, utility line towers, sewer outfalls, tunnels and other related structures .
A committee of industry-wide professionals involved in the support, understanding and application of micropile foundation technology. The committee operates jointly with the ADSC Micropile Committee visiting the state of practice regularly through seminars and global workshops and has an international arm, the International Society for Micropiles (ISM), to further technology transfer across the globe.
- Project Information Management Systems
This committee educates the DFI membership on trends, technologies, and specifications related to information management, including the digitalization, compilation, visualization, and analysis of data collected during construction. Committee members include owners, contractors, and consultants.
- Seepage Control
DFI and federal and state agencies established the Seepage Control committee as a collaborative forum to discuss industry best practices for seepage cutoff and foundation improvement for water infrastructure projects.
- Seismic and Lateral Loads
This committee focuses on the unique issues of seismic design and construction as well as related concerns of other lateral load issues that apply in marine applications, ice and permafrost regions.
- Slurry Wall
A committee of industry-wide professionals involved in the use, advancement, understanding and application of slurry wall technologies for cutoffs and earth support. The committee comprises DFI members experienced in design and construction of seepage cutoff, vertical barrier systems and temporary and permanent earth support works.
- Soil Mixing
This committee of designers, contractors, researchers, equipment suppliers and owners are involved in the support, use, and understanding and application of soil mixing technology.
- Subsurface Characterization for Deep Foundations
This technical committee focuses on considerations for site investigation for the design and construction of deep foundations.
This committee comprises multinational participants who study and promote the use of sustainable foundation construction practices. Topics of focus include re-use of existing foundations, construction site waste management, carbon emissions calculation, geothermal energy foundation systems, efficient use of resources/local supplies, use of low energy materials, use of green fuels and economy and efficiency in equipment.
- Testing and Evaluation
A committee of industry-wide professionals involved in the use, understanding and advancement of instrumentation, monitoring and testing methods for the inspection construction and integrity and capacity analysis of deep foundation systems.
- Tiebacks and Soil Nailing
A committee of industry-wide professionals who design, construct and supply equipment for temporary and permanent support of retaining structures using tiebacks and soil nailing techniques. This committee often collaborates with ADSC's Anchored Earth Retention Committee.
- Tunneling and Underground Systems
The purpose of this committee is to identify and facilitate the advancement of new methods and technologies for design, construction, inspection, maintenance and operation of tunnels and underground systems.
- Women in Deep Foundations
This committee is comprised of women and men who are advocates for retaining women in the deep foundations industry. The goal is to foster greater success and interest of professional women in the industry by promoting networking events, endorsing outreach and building mentoring relationships.
