In the implementation of Quality Control (QC) on construction projects, data collected through observation methods and routine inspections often indicate various problems that arise in the field. QC results reflect the real conditions of the project and various problems that must be addressed to maintain the quality and safety of construction. Use of observation methods and Literature Studies: Data is collected from productivity carried out every day at the internship site or in related journals. An observation method in QC is a direct monitoring technique used to supervise the implementation of work in the field. Thus, the results of the study indicate that the amount of steel reinforcement needed must meet 0.48% of the concrete cross-sectional area, according to design standards to maintain the strength and stability of the structure. This experience provides new experiences to problems with new knowledge, which includes the ability to work together, communicate, and identify problems.
