Generally speaking, in Indonesia, safety and security at work (also widely known as K3, Keselamatan and Keamanan Kerja), had not been primary concern in the general and construction Works. It is shown in the high figure of work accidents in construction works, reaching approximately 7-8% of the whole sector of workers. Which is in turns contributes 6.45 % to Indonesian GDP as cost on national level. That is why the concern to K3 must be developed as corporate culture, not only to protect workers’ safety and security but also to increase the performance of the firms.
