Safety culture not only affects the productivity but also the competition between similar core businesses. The concept of safety culture is a new concept in the construction sector. Construction sector has a narrow building period and high employee turnover. PT. MK Building Department won the tender for the Renovation of Gelora Bung Karno Main Stadium with 14-months term. This study aims to determine the level of safety culture maturity of PT. MK on the Renovation Project of Gelora Bung Karno Main Stadium (SU-GBK). Data were collected qualitatively (FGD, observation and in-depth interview) and processed by quantitative method for in-depth analysis during May–July 2017. The sample in this study was chosen by stratified random sampling and determined by representation in population. Safety culture maturity score was grouped by variable and job level groups. Safety culture maturity level was grouped based on Bells Curve in five level of maturity that are pathologic, reactive, calculative, proactive and generative. PT. MK SU-GBK Renovation Project focuses on system planning, but the score of implementation and evaluation in safety management system is still weak. Project’s managements have realized the importance of humans in a system. Workers are an important asset for the company. The awareness of the safety built by project leaders (management and supervisors) is still in the early stages and has not been felt by most workers. Safety is not reflected in daily activities because this project still needs organizing the work organization. From one to five, safety culture maturity level in PT. MK SU-GBK project can be categorized into calculative level with an average value being 3.19. The safety management system runs based on existing data. It is fully controlled by the management without the active participation of workers. Calculative-level organization is an organization that is not ready for the safety culture.
