Piers and pilings are structural elements used in construction, but their functions and designs differ.
Piers are vertical support structures that elevate platforms or walkways above water, soil, or other surfaces. Usually composed of vertical columns anchored into the ground or foundation and connected by horizontal beams or girders, creating a framework supporting whatever lies above. Piers can also support bridges, docks, and piers along waterfront areas.
Pilings, conversely, are long cylindrical structures made of timber, steel, or concrete that are driven or drilled into the ground to form foundations for systems such as buildings, piers, bridges, and other infrastructure. Unlike docks seen aboveground, pilings typically remain hidden underground; they aim to transfer weight from a structure onto subterranean soil or rock while providing support and stability.
The main difference between piers and pilings is that piers are above-ground vertical support structures for elevated platforms. In contrast, pilings are below-ground …
