The combination of both function coefficient method and logframe approach was employed to construct the performance evaluation index system of coordinated management of construction projects. The evaluation index system of coordinated management of construction projects was constructed from four aspects, including performance evaluation of target coordinated management, organization coordinated management, interest party coordinated management, and sustainable development of project and organization. In addition, the way was given to calculate the comprehensive performance evaluation coefficient of coordinated management of construction projects, quantifying the evaluation of the performance of the coordinated management of construction projects. In the end, the method to construct index system and calculate the coefficient was proved by an empirical study. This method can judge the function of coordinated management of construction projects efficiently.
