This study aims to contribute to the safety and quality improvement of reinforced concrete piloti structures in the jeju island by analyzing the types of re-bar arrangement defects that occur during the construction of these structures through structural supervision. The scope of this study was limited to the reinforcement arrangement defects in transfer columns, transfer beams, walls and slabs of reinforced concrete piloti structures subject to structural supervision. The types of defects examined included re-bar development, beam main bar spacing, stirrups, tie-bars, slab opening reinforcement and wall U-bar arrangement. The conclusions reached from this study are as follows: (1) Defects for spacing between layers of main bars in beams appeared at 30 sites out of 44 sites, and these defects cause bending failure of beams. (2) Defects in the stirrups and tie-bars cause failure of members due to internal concrete fall and buckling of the main bars. (3) Defects were found to be 10 sites out of 44 sites for the development of the column main bar and 3 sites out of 11 sites for U-bar construction of the wall, and these defects cause the development failure of the re-bars. (4) Defects around the slab opening were found to be 2 sites out of 11 sites, and these defects cause cracks around the opening.
