Investigation into the relationship between rework and site supervision in high rise building construction in Indonesia
MetadataShow full item record
he quality of site supervision has a major influence on the overall performance and efficiency of construction projects. Inadequate supervision is believed to be one of the major causes of rework. Therefore, experienced and well-trained supervisors have an important role in minimising the amount of rework due to construction defects. This paper argues that the quality of site supervision Indonesia is directly related to the supervisor's level of experience gained through formal training. Hence, the paper attempts to explore the relationship between the quality of site supervision, expressed as training cost, and the rework cost borne by contractors in high-rise building construction. Based a comprehensive data collection targeting ten building construction sites in Indonesia, this paper suggests that inadequate site supervision is a principal cause of rework during construction. It also offers insights into the statistical relationship between the cost of supervisors' training and the cost of rework. Based on the relevant literature and accounts from site managers interviewed during the course of data gathering, this paper offers practical recommendations to upgrade and maintain construction supervisors' skills in Indonesia.
