PROBLEM TO BE SOLVED: To provide an execution management device of a pile driving method, systematically taking respective measured values obtained by a measurement sensor into a computer, and checking the same in real time to make a decision by the use of analysis software in which requirements necessary for determination such as a determination important item, a determinaiton condition and criteria are set. SOLUTION: The vertical degree of the shaft center of a pile 6 is measured by a vertical sensor 16, turning torque, a rotational frequency, and pressure are respectively measured, and a propulsion speed in rotary press-in of the pile is measured. A time until the respective measurement data meet designated conditions and the tip of the pile reaches a hard ground layer is measured, and after the press-in depth of the pile is measured, a rotation operation is stopped to drive the pile only by press-in. At that time, the turning torque, the rotational frequency, the pressure, the propulsion speed, the depth and the time are measured by the sensor, and checked and analyzed in real time by the computer 30 of a construction machine by the use of analysis software 31 for previously sampled subsurface exploration data to make a decision and execute work.
