First, second and third generation models can be identified, but they all have shortcomings. This paper puts forward a new model, fuzzy calculation model, based on lots of data of the finished proiects. Through actual application, it is proved that the model is accurate and quick in calcalation of construction.展开更多

The mean,variance and the risk level under the above-mentioned two circumstances have also been compared with a case study.Also the sensitivity analysis of cost risk has been probed into. The result indicates that the model which takes into ac-count correlation is more objective, and the model which ignores the circumstance of correlation normally underes-timates the risk level of project cost.展开更多

The aim of this research is to predict the early project cost using neural network. Early project cost represents a key component in business unit decisions. The most important factors influencing on the parametric cost estimation in construction building projects in Gaza Strip were defined and investigated. A questionnaire survey and relative index ranking technique were used to conclude the most important factors. Fourteen most effective factors were identified. One hundred and six case studies from real executed construction project in Gaza Strip were collected for training and testing the model. The cases were prepared to be used in cost estimate neural networks model. Eighty percent of case studies were used to train and test the model. The remaining 20% was used for model verification. The results revealed the ability to the model to predict cost estimate to an acceptable degree of accuracy. The minimum squares error with 0.005 in training stage and 0.021 in testing stage were recorded.展开更多

At the same time, according to construction project cost management, the scientific management of the contract, can promote the reasonable and balanced investment cost allocation in the quality and safety and other aspects of the project, so that the construction project can obtain higher added value, and to further promote China＇ s economic construction and accelerate the pace of the city. This paper first briefly elaborates our construction project cost of the contract management on the present situation, and some problems are analyzed and discussed, and then puts forward some suggestions on the measures and countermeasures for cost management of construction engineering contract.展开更多

In terms of construction project, cost management and control is the core of the project and is implemented throughout all stages of the project, so it is complicated system engineering. In this paper, construction project cost composition and its management measures are mainly discussed.展开更多

Control of the project cost in the project implementation is mainly divided into bidding, contracting, construction and settlement. The following is the analysis and discussions of the author＇s experiences to the control of the project cost in the project implementation and the management measures.展开更多

The construction cost management industry is surely no exception. To improve the application of computer technology in construction cost management industry, this thesis would respectively discuss and analyze the importance of computer technology application in construction cost management, status quo of computer technology application in construction cost management, measures of improving computer technology application in construction cost management as well as the development prospect of computer technology application in construction cost management. The author is striving to arouse the attention and exploration of relevant departments as well as practitioners in the same industry.展开更多

This paper not only improved the tendering and bidding stage method of cost control in construction project in our country, and improves the method system of engineering cost control.展开更多
