PURPOSE:To make a correction favorably performable in terms of working property by predicting any change in a building position quantitatively on the basis of experimental data, compensating it in direction and quantity to be changed to a scheduled building position of other steel frame pillars on the basis of the value, and performing each position change. CONSTITUTION:A displacement direction D0 and a displacement value A0 to an upper end position P'0 and a scheduled building position of a central steel frame pillar C0 among nine steel frame pillars C0-C8 being set up in grille form are detected with a three-dimensional surveying system 1. Next, plural pieces of wires 2 is stretched in the circumferential direction and this tensile condition is adjusted into correction to the scheduled building position and temporarily locked. Then, displacement directions D1-D8 and displacement values A1-A8 to each building position of the remaining eight steel frame pillars C1-C8 are detected as well, and these steel frame pillars C1-C8 are corrected to the scheduled building position on the basis of the value and experimental data. Rebuilding takes place at each block B, and the steel frame pillars C and steel frame girders G are connected together in an assembling state, while the steel frame pillars C and the steel frame girders G extending over in an interval between adjacent blocks B and B are also connected together in this assembling state.
