The Security Cost as Part of Construction Safety Cost: Case Study of Flats Construction

Abstract

Indonesia is currently experiencing a rapid increase in infrastructural development, including the construction of flats. This has led to a rise in construction-related accidents due to the lack of an appropriate safety budget for projects and further worsened by the separatist movement, theft, and vandalism, specifically in the eastern part of Indonesia. Therefore, this research aims to prove that factors, such as construction location and building height, affect construction safety costs in flats. The research found that safety costs consist of 3 parts, namely general, specific, and security costs. The construction safety cost was simulated using Monte Carlo analysis, which showed the amount of safety cost in flats construction in Eastern Indonesia, is higher than the Western part. Furthermore, the safety cost for more than 3-storey flats is higher than those for 3-storey. This shows that the location affects the cost of additional security. In addition, the building height also affects construction safety costs due to differences in the scope of work contained in the WBS.
