The concrete foundation structural section drawing illustrates a detailed foundation construction layout showing reinforced concrete footing beam, and base support elements. The drawing indicates a concrete base layer with a strength of f c one hundred kilograms per square centimeter and a thickness of five centimeters placed as the foundation bedding layer. Above this layer, a reinforced concrete footing beam with strength f c two hundred fifty kilograms per square centimeter is provided with four reinforcement bars and stirrups placed at twenty centimeters spacing. The footing beam section size is twenty by fifty centimeters and includes chamfer finishing for structural durability. The drawing also identifies the finished platform level at plus zero point twenty meters, which represents the floor elevation relative to the natural ground level.
