Vertical posts that are driven into the earth to serve as the foundation anchor of a building are called what?

• A. Columns
• B. Pillars
• C. Pilings
• D. Beams

Answer: (C)

Pilings are long posts driven deep into the ground to reach stable soil or rock and carry the building’s load down to that level. This approach is used because surface soils may be weak or unstable, so the foundation anchors go down to stronger layers to prevent excessive settlement and resist forces. Pilings can be made of timber, steel, or reinforced concrete and may be driven or drilled into place. Column and pillar refer to vertical structural members that carry loads from above but are typically above ground and not necessarily driven deep into the earth. Beams are horizontal members that transfer loads between supports. The distinctive feature of pilings is their depth-driven nature to form the foundation anchor.
