Comprehensive Control Technique of Reliability in Large Construction Project Management

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.     

A Discussion on How to Control Project Cost during Construction Stage

In this paper, how to effectively control building cost under the current situation is discussed, due to that the engineers take part into project management only in the stage of construction. It points out that the engineers should notice the following issues when applying cost control: they should be experienced with necessary knowledge on building cost and contracts control, analyze each cost in bills of project volume carefully, sign a set of reasonable contracts, pay attention to the site sign, understand their skills of claim for compensation and pay much attention to cost control during settlement stage.     

Fuzzy Analysis Method for Evaluating the Qualityof Project General Supervision Engineer

Since the implementation of the new construction system in 1988 in China, this system has gone through three phases: trial phase(1988-1993),development phase(1993-1995),and comprehensive application phase from 1996.Construction supervision as a new management system has profound effects to the whole process of a construction project, in particular, to the three conventional objectives, that is quality, cost and construction time. The new management system has to a large extent brought the traditional problems of extended construction time, uncontrollable cost and unsecured quality to a normal practice. Construction supervision is a management activity with request of high intelligence. The performance of this activity is closely related to the quality of project general supervision engineer. This paper identifies the basic elements that a proper project general supervision must have. By applying the fuzzy analysis principle, this paper presents a quantitative model for evaluating the quality of project general supervision engineer.It provides an applicable approach for project clients when general supervision engineers are to be chosen.

Approach to Effective Control on the Project Investment

In this paper, in allusion to the three kinds of serious overvaluation (the budgetary estimate of project construction exceeds the rough estimate, the budget exceeds the budgetary estimate and the final accounts exceed the budget) causing uncontrollable project investment often appeared in domestic project construction,the main causes for that are analyzed. That is, the frequent project change and the malpractice of the cost managing system. In this paper, according to some real projects,the kinds and causes of project change are clarified and the malpractice of the cost managing system is analyzed. The effective approaches of reducing the project change, especially the united surveying and improving the cost managing system in order to make the effective control of the project investment are realized.

Discussion about Saving Energy in Refrigeratory

Food refrigeration is regarded as a high energy consuming trade. Under the long period system of state operated enterprise,there are many phenomenons of ignoring energy management and wasting energy. Energy consuming is not very clear for production.Consuming in our country is far more than the international standard and there is a distance between the middle_westland and the eastland. As a enterprise that faces the international market,it is important for it to strength the management so that the cost can be reduced. Considering those phenomenons of ignoring energy management and wasting energy in refrigeratory at present, some measures such as improved the unreasonable operation process, strengthening the energy management and automation to realize automatizing operation are improved to reduce the cost for refrigeratory trades.     

Application of the Pattern of Construction Management Contract in Large-scale Project in Shanghai

This article states systematically the fundamental conception of the mode of construction management general contract, the contract structure and the organization structure through the analysis of the construction characteristics of Shanghai large-scale projects, considering the situation of China and the characteristics of this line. It also summarizes the characteristics of the mode of construction management general contract through the example of the Pudong International Airport Construction. The mode of construction management general contract not only meets the needs of construction technique in bettering the design of construction project building, but also releases the pressure in middle and later management of construction project building and overcomes the deficiency of the long-term building period, hard-to-control investigation brought by the problem of design, purchase, construction divided from and restricted by each other existed in the traditional contract mode. It also helps the contractor to provide socialized, specialized, commoditized service for the contractor. Helps to overall arrangement, economized investment, management level improve ment can be given. So it has the superiority in super large-scale projects construction compared with the traditional construction management.
