In this research the results of positive value which means the higher the implementation of occupational safety and health, the higher the performance of the construction project. The results showed that simultaneously the application of Occupational safety and Health (K3) to the performance of the affected construction project is 3.9% and is seen from the significance value of 0.013 T table then Ha accepted and Ho rejected.

The sample determination in this study amounted to 158 people using the Cluster Sumpling.

Wijaya Karya on the PLTMG Sumbawa construction project amounting to 289 people. The method of data analysis used is a simple regression and correlation of product moment.

Data collection method is done by questionnaire, documentation. The method used in this research is this type of quantitative study. The theory used in this research is the implementation theory of the Occupational Safety and Health Management System (SMK3), which relates to occupational safety and Health (K3), work environment and performance.
