a)Investigation After investigation to the defective concrete area of columns in grid line 1-2/Ba-Ca at GF level, there is unauthorized and unapproved repairing work done on honeycomb of concrete. With no remedial measure considering to the reparation which might disintegrate concrete in structure do we not tolerate such repairing method. Hence, workers must follow approved method statement to their repairing work over any defective concrete structure. |
b)Remedial Proposal 1. Remove cement patches on honeycomb of concrete 2. Create construction joint via using hydraulic breaker to roughen up defective concrete surface 3. Patch cement into defective concrete area until smooth finishing surface is reached |
c)Precaution Concrete structure should be elaborately inspected following the removal of formwork, and we must notify residential engineer the location of defective concrete before start repairing |
d)Inspection Inspection to the reparation of defective concrete area in columns will have been arranged with residential engineer right after the repairing work is completed |
