Deep Foundations Institute (DFI) is an international association of contractors, engineers, manufacturers, suppliers, academics and owners in the deep foundations industry. [2]
DFI was incorporated as a 501(c)6 association in January 1976. [3] It was founded by Jack Dougherty and Hal Hunt during the “Pile Talk” seminars and became a multidisciplinary worldwide membership organization.
DFI currently supports chapters in Europe, Middle East and India.
In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water, transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics in the design of foundation elements of structures.
A drilling rig is an integrated system that drills wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers. Drilling rigs can sample subsurface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures. The term "rig" therefore generally refers to the complex equipment that is used to penetrate the surface of the Earth's crust.
A pile driver is a heavy-duty tool used to drive piles into soil to build piers, bridges, cofferdams, and other "pole" supported structures, and patterns of pilings as part of permanent deep foundations for buildings or other structures. Pilings may be made of wood, solid steel, or tubular steel, and may be driven entirely underwater/underground, or remain partially aboveground as elements of a finished structure.

The International Facility Management Association (IFMA), originally the National Facility Management Association (NFMA), is a professional membership association for facility management professionals. IFMA's global headquarters office is located in Houston, Texas, USA. IFMA also employs staff located in Antwerp, Belgium; and Shanghai, China.
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site.
Crosshole sonic logging (CSL) is a method to determine the structural integrity of drilled shafts and other concrete piles.

The Family Motor Coach Association (FMCA) is an international organization of families who own and enjoy the use of recreational vehicles. Although the name says "motor coach" FMCA has welcomed all RV types since 2017 and towables are becoming a viable part of the organization. In 2023 the organization added a category of membership called "Pathfinders" for those thinking of joining the RV lifestyle and wanting to learn more about it before they buy. These members get access to all of the benefits including FMCA University where they can explore what it takes to travel in, own and maintain an RV.
