PROBLEM TO BE SOLVED: To provide a construction method for a foundation structure of such type that a foundation of a structure is put on a head part of an existing pile buried into the ground to form a joint condition of the existing pile and the foundation of the structure into a semi-rigid joint condition conforming to prospects in design. SOLUTION: This construction method for the foundation structure comprises a process for burying the existing pile 1 provided with a tool engaging with a rotary press-fitting device in the pile head part protrudedly into the ground by using the rotary press-fitting device, a process for removing the tool, a process for forming a cavity E enlarged toward a downward part between a side face of the pile head part and an inner peripheral face of a form 3 by putting and covering the mold 3 whose inner peripheral face is inclined on the pile head part, a process for placing leveling concrete around the form 3 while preventing flowing-in of concrete into the cavity E, and a process for placing foundation concrete becoming the foundation 2 of the structure on the hardened leveling concrete.
