After analyzing the current researches with the three-major-goal management: quality,cost and time,on the construction project and aiming at the existing issues,this article puts forward a new method.This method identifies the reliability of every fundamental module(subsystem) suitably,which based on the current standards to analyze and classify the large construction procedure,and was constituted by the construction procedure.Also was considered the three-major-goal(quality,cost and time) of every module.Then the reliability of the large construction project was calculated,the qualified standards of reliability were evaluated,and the general and particular frame was optimized.Furthermore,it raises a new conception of the comprehensive control technique considering the reliability of the three-major-goal synthetically.This article explores a new way to ensure the three major unified goals: quality,cost and time,of the construction project management,and makes sure that the process of the construction project was in an ideal condition.
