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.
