Abstract

Safety is a mandatory requirement in Indonesia's construction industry. As part of continuous improvement efforts, a state-owned construction company conducted a safety climate assessment to identify implementation gaps, and formulate recommendations for improvement. This study utilizes a quantitative survey of 1,165 respondents and interprets the measured value in the NOSACQ-50 index to identify the implementation gap of the assessed company‘s safety climate. The assessment result indicates that the company‘s safety climate is in the "Good" category (mean 4.31) with strengths in formal rules and communication. However, the assessment shows that the assessed company‘s safety climate scores a lower point in the workplace condition, individual risk appreciation, and leaders‘ commitment categories, which implies a pattern of "strong formality, weak reality." The persistence of unsafe conditions (UC) despite high scores suggests that safety aspects are not yet embedded in the production system design. Procedures alone are not enough to encourage mature safety implementation. Individual awareness of safety risks in the field is also necessary, and this awareness must be actively promoted by top management.
