The high number of accidents indicates that a good system of safety and health management is required. The purpose of this study is knowing the relationship of safety cost and OHS performance in building construction in Jabodetabek with statistical methods. The result shows that safety cost’ components which have the most influence to control OHS’ risks are rotary lamp, life line, and tools license permit. Moreover, safety cost’ components that influence accidents the most are evacuation route, BPJS, safety vest, and worker’s identity cards. Index Term-- Safety Cost, Safety Performance, OHS Risk Control, Accidents I. INTRODUCTION Occupational Safety and Health (K3) is a very important aspect, especially in the construction sector. In its work, the construction sector involves jobs with substantial risk of harm. K3 management system in Indonesia can be said still not well implemented, indicated from the high number of work accidents that occurred in Indonesia. Based on data of accident cases from PT. Social Security of Workers (Jamsostek), there were 95,624 cases in 2006, 83,714 cases in 2007, 94,736 cases in 2008, 96,314 cases in 2009, 98,711 cases in 2010, and 99,491 cases in 2011. Of 31.9 % of the cases are from the construction sector. These figures support the argument of high occupational accident risk in the construction sector, including building construction. Construction organizers tend to underestimate the OSH management system as it is considered to only add to the cost budget in construction works. Safety and Health Expenditures for construction sector are regulated in Circular Letter no. 66 / SE / M / 2015 on the Cost of Operation Management System Occupational Safety and Health (SMK3) Construction of Public Works. However, because it is considered as a burden, construction operators tend to ignore the implementation of SMK3. In a study of 25 building projects undertaken by Gurcanli et al. (2015), some construction service firms actually allocate lower K3 costs along with increased project size and height. In fact, the cost of K3 does not reach 5% of the total cost, ie the research is 2.6% of the total cost. Based on research conducted by Muhammad, et. al. (2015), explained that according to Smallwood, J. (2004), the estimated cost allocation for OHS management implementation in construction companies is 0.5% to 3% of the total project cost, and work accident costs exceed 5% of the total project cost. Based on some existing research, the cost of running SMK3 in building construction projects is often allocated very small to reduce total cost burden. Construction companies usually consider allocating funds for OSH management for construction projects, including building construction projects, as one indicator that could harm the company. This is unfortunate, because the high number of occupational accidents in the construction sector needs to be overcome by the improvement of OHS performance. The purpose of this study are: 1. Identify the cost component of the implementation of SMK3 allocated to the building construction project. 2. Identify the components of the cost of implementing SMK3 in building construction projects to improve OSH performance. 3. Identify the cost component of the implementation of SMK3 which is a priority to improve K3 performance. 4. Analysis the effect of SMK3 implementation cost on the performance of K3 in building construction project. II. THEORITICAL REVIEW OHS performance, by definition from OHSAS 18001: 2007, is a measurable outcome of the management of OSH risks in an organization. Measurements of OHS performance include measuring the effectiveness of control carried out by the organization. OHS performance can also be measured by comparing against OSH policy, OHS objectives, and other OHS performance requirements. The organization shall establish, implement and maintain procedures to monitor and measure the OHS performance on a regular basis. Such procedures are important for qualitative and quantitative measurement according to the needs of the organization; monitor extensions that enable the organization's OH & E objectives to be achieved; monitor the effectiveness of controls for health and safety, proactively measure
