PURPOSE:To easily and quickly perform a foundation work by a method in which a hole a size larger than the column form of a building, reinforcing bars are arranged for the column legs, and concrete is placed. CONSTITUTION:A size larger hole 2 than a column form is excavated in the column leg portion of a building of bedrock 1, and reinforcing bars 3 for the column leg are arranged in the hole 2. Concrete 4 is then placed into the hole 2 to integrally fixe the column leg and the bedrock 1. Columns and joint beams are constructed on the column legs.
