Fig. 5. (a) vertical crack in A3 column; (b) vertical crack in B3 columns . The structure's beams have cracked and past attempts at repairs appear to have failed. The bottom of nearly all the structure's corner beams has been restored. The cracks between the beam wall junction and the bottom repair work are shown in Fig. 6.

The moisture of the first-floor roof slab may be due to the terrace's incorrect slope and insufficient drainage system before the construction of the upper stories. Fig. 7 shows the existence of lime marks and dampness at several locations on the ground floor slabs. The marks on the ceiling show that the slab was first treated, but it appears that the treatment was unsuccessful.

All structural elements observed failures, such as the columns, beams, and slabs, have been distressed and deteriorated. Thus, only NDT rather than the semi-destructive test is advised based on the ground-level situation. After assessing the state of the building, sensitive areas have undergone a thorough and efficient examination.
