ABSTRACTThe development of the construction process has increased rapidly, where the maincontractor who already get the contract further give it to the subcontractors. This isdue to the complexity of a construction job, so the main contractor requiresspecialist contractors for certain jobs requiring special skills. To obtain suchcompetent subcontractors, it is a must to select the appropriate subcontractors. Inselecting the competent subcontractors, the main contractors assign each individualcriterion. Due to the selection process, it is important for the main contractors toknow and identify the most influential criterion of the subcontractors. This researchis conducted by the main contractors who live in Kota Kupang, East NusaTenggara. The method and data analysis are using AHP method supported byexpert choice software. Subcontractor selection are divided into six aspects: generalaspects, financial aspects, technical aspects, managerial aspects, safety aspects andaspects of the company's reputation. As a result, aspect that influences the selectionof subcontractors is the financial aspect. While the criteria that influence the valueof criteria deals and sub criteria with the lowest value.ABSTRAKProses pelaksanaan konstruksi semakin berkembang, dimana kontraktor utamayang mendapatkan kontrak (pekerjaan) selanjutnya memecah pekerjaan tersebutdan membagi (menyerahkan) kepada subkontraktor.
