[ABSTRAK
Tingginya angka kecelakaan kerja pada industri konstruksi masih menempatiposisi tertinggi di antara industri lainnya yang menyebabkan kinerja keselamatandan kesehatan kerja menurun. Salah satu penyebabnya adalah keterlibatan banyakpihak, diantaranya adalah subkontraktor, dimana internal perusahaan ini masihmemiliki manajemen yang kurang memadai. Oleh karena itu, perlu diketahuifaktor-faktor dominan yang mempengaruhi pengadaan subkontraktor pada tahapperencanaan dan pelaksanaan yang mengacu pada PMBOK 2013 sebagai panduandengan metodologi yang spesifik, agar dapat meningkatkan kinerja keselamatandan kesehatan kerja. Metode penelitian yang digunakan adalah survey dan studikasus. Data diolah dengan analisa statistik dan analisa faktor. Berdasarkan hasilpenelitian ini peningkatan kinerja K3 didominasi oleh faktor integrasi yang baikuntuk memenuhi tuntutan kerjasama dalam aspek K3.

ABSTRACT
The high number of occupational accidents in the construction industry stilloccupies the highest position among the other industries that cause occupationalhealth and safety performance decreases. One reason is the involvement of manyparties, including subcontractors, where an internal company still have inadequatemanagement. Therefore, is need to know the dominant factors affecting theprocurement of subcontractors on planning and implementation process referringto the PMBOK 2013 as a guide to specific methodology, in order to increasesafety and health performance. The research method used are survey and casestudy. Data processed by statistic analysis and factor analysis. Based on the resultsof this research, occupational health and safety dominated by good integration tomeet the demands of cooperation in the aspect of K3 factor.;The high number of occupational accidents in the construction industry stilloccupies the highest position among the other industries that cause occupationalhealth and safety performance decreases.
