Increased efficiency and effectiveness in construction services company require system of planning, implementation, and control of three aspects : quality, time and cost. Cost control is a very important factor to prevent cost overrun, a condition in which there was an additional charge at the end of the project and gain experience reductions. In construction projects of material and equipment costs are the largest part of the project, its value could reach 50-60% of total cost of the project. Given this researceh, the reader should be able to know how much the relationship or influence deviation material costs during the construction period of the project cost performance. The data used in this study are primary data and secondary data. Primary data obtained from the questionnaires to the respondents (contractor), while secondary data obtained from the study of literature relating to the existing problems. The data then processed using statistical analysis with SPSS 21.0. Statistical analysis was performed among others : correlation and intercorrelation analysis, factor analysis, analysis of decision variables, regression analysis and testing models as well as the validation test. From the test results obtained independent variables determining deviations material costs during the construction period are correlated to the performance of th cost of the project are : the addition of material resources needed due to errors in planning the scoupe of work (X2) and material wastage due to change in material conditions during the delivery process (X43).
