Material is everything and all requirement needed during the project construction to support the project activities so that the project can produce the goal achievement. Material management includes the planning and control related to the material viewed from various sectors including procurement, supply, purchase, delivery, acceptance, warehousing and distribution. One of the problems often faced is the material procurement delay. The material is not available when it is required and this condition causes the reduction of the workers’ productivities. In addition, the workers’ productivities reduction also affects the time performance of the project construction. The project manager needs to control the various activities in the project location. One of the importing factors is the time performance. This research aims to identify the most dominant factor in the material management affecting the time performance and to analyze the material management risk effect to the time performance in fly over project construction in Banda Aceh. The observation done to construction implementation teams (stakeholders) in Fly Over Project in Banda Aceh, they are the owner, supervision consultants and contractors. The statistical analysis used is validity test, reliability test, descriptive analysis and multiple linear regression. The most affecting material management risk factor to the time performance in the fly over project construction is quality control factor. It means that if quality control factor can be well handled, the time performance of the project construction will improve.
