The construction cost is usually calculated based on the unit price analysis using three major coefficients for materials, equipment and labor. Among the three, the labor cost is more difficult to obtain where uncertainty is occurred due to the lack of performance standardization. This paper describes a study with the purpose to acquire an approach model in estimating labor coefficient where the uncertainty is applied. The study is conducted to labor involved in the industry and based on length of work experience that influences labor performance. Reference of labor coefficient is gathered from the National Standard of Indonesia (NSI) and is examined toward the range of coefficient from the data. The correlation and equation between length of work experience and labor performance are computed. By doing so, testing NSI on average time obtained form the study, regression analysis output and its equation could be used as the correlation between length experience and manpower productivity. This productivity is a transformation of the coefficient in unit price analysis.
