This Architectural Drawing is AutoCAD 2d drawing is details of A postlike foundation member used from prehistoric times . Pile, in building construction, a postlike foundation member used from prehistoric times. In modern civil engineering, piles of timber, steel, or concrete are driven into the ground to support a structure; bridge piers may be supported on groups of large-diameter piles. Piling works by inserting large amounts of wood, steel or concrete into the soil of the ground. The deep insertion of these elements ensures a sturdier base for the construction project to take place. For more details and information download the drawing file.
