Assessment of Overhead Cost in High-rise Building Construction Projects

Abstract

This research investigates the overhead cost of high-rise building construction projects. Primary and secondary data of the projects having the project’s total value less than 1000 million baht were surveyed and collected from contractors in Bangkok. The preliminary cost included employee, labor, labor camp, electricity and water supply, and construction equipment cost. The results showed that the preliminary cost of high-rise building construction projects increased by increasing the project's total value. The average preliminary cost was 18.44% by the project's total value, which included 21.77% employee, 52.05% labor, 2.03% labor camp, 6.77% electricity and water supply, and 4.04% construction equipment, respectively. The obtained information should be beneficial in estimating high-rise building construction projects for effective bidding and project management.
