An innovative methodology for probabilistic estimation of ground condition and construction time and costs is proposed, which is an integration of the ground prediction approach based on Markov process, and the time and cost variance analysis based on Monte-Carlo （MC） simulation. The former provides the probabilistic description of ground classification along tunnel alignment according to the geological information revealed from geological profile and boreholes. The latter provides the probabilistic description of the expected construction time and costs for each operation according to the survey feedbacks from experts. Then an engineering application to Hamro tunnel is presented to demonstrate how the ground condition and the construction time and costs are estimated in a probabilistic way. In most items, in order to estimate the data needed for this methodology, a number of questionnaires are distributed among the tunneling experts and finally the mean values of the respondents are applied. These facilitate both the owners and the contractors to be aware of the risk that they should carry before construction, and are useful for both tendering and bidding.展开更多

At present, the whole process cost management has become the core of engineering construction project cost management. In order to improve the management level of construction engineering, the whole process cost management can solve the problems of traditional management. The application of the whole process cost management can qualitatively analyze each relevant element, dynamically prevent and control the possible situations in the engineering construction and further promote the smooth progress of the construction project. In order to play the role of whole process cost management in reducing project investment and saving cost, this paper introduces the concept of whole process cost management, analyzes on the problems existing in the current project cost management, and finally puts forward corresponding methods from the angle of whole process cost management.展开更多

The emergence of PPP mode makes up for the shortcomings of BOT mode, carries out a new management on the highway project cost, and gives comprehensive consideration from the early stage of the design scheme to maximize the project benefits. However, there are some problems in the practical application of PPP mode, which needs further innovation and development to make PPP mode play a greater role in the whole process cost management of highway engineering.展开更多

Due to the short application time of this model, there are still many links to be improved in practice. Based on the actual situation, this paper analyzes and studies the whole-process cost management model of government-invested projects, explores the causes of the problems, finds out effective measures, gradually adjusts and solves the problems, optimizes the cost management model, and then realizes the rational allocation of resources. Next, the article discusses the whole process cost management of government investment projects.展开更多

However, high-quality construction often requires high cost, so the contradiction between quality and cost puzzles more and more construction units. In order to solve this problem, this paper carefully analyzes the project cost structure and puts forward the relevant value of the whole process project cost, hoping to help relevant practitioners promote the whole process project cost in the industry and make their own contribution to creating a good market environment.展开更多

For municipal projects, the source of project funds is mainly from financial allocation or local fund raising. In terms of fund control, it must be audited by relevant government departments, and in terms of project budget estimates, it also needs the intervention of local governments. Therefore, in the construction of municipal projects, in order to effectively ensure the smooth progress of the project, further improve the quality of the project and speed up the progress of the project, the relevant units must do a good job in the whole process cost management.展开更多

Construction engineering is a relatively large project. It is complex not only in terms of the quantity and time cycle of construction engineering, but also in terms of the cost and manpower investment of construction engineering. Aiming at the valuation process of the whole process of construction project cost, this paper summarize that the project cost is the key basis for controlling the project cost, and puts forward that only by reasonably controlling the project cost, can we curb the occurrence of various problems such as Jerry building and shoddy goods caused by ultra-low price bidding, effectively ensure the construction quality and improve the construction efficiency.展开更多

In the process of engineering, using the whole process cost method can effectively control the project cost, and then achieve the comprehensive control and management of the project, so as to better improve the development pace and market competitiveness of enterprises. However, because there are many influencing factors in the construction of related construction projects in our country, in order to really do a good job in the whole process of cost management, it is necessary to do a good job in the analysis and control of each link in the actual process of the project, so as to improve the control effect of the project cost, enhance the development competitiveness of enterprises and help enterprises to be better and more sustainable development in the fierce market economy.展开更多

The effective control of construction project cost mainly lies in the investment decision-making and design stage before project implementation. At present, China's construction projects are still in the development stage. For the whole process of cost control management, it is necessary to keep in touch with the investment estimation stage, design estimation stage, bidding stage, construction stage and settlement stage. Relevant departments and units should pay special attention to the comprehensive understanding, reasonable determination, effective control and practical application of cost control management.展开更多

There are many factors that affect the project cost, such as the formulation of national policies, the fluctuation of material labor price, the local geographical environment of the project, etc., which are complex and run through all stages of the construction process and have great impact. In the actual operation of most construction projects in our country, the phenomena such as the final completion settlement investment exceeding the construction drawing budget, the construction budget exceeding the preliminary design budget, and the preliminary design budget exceeding the feasibility study estimate often occur. The reason is that there is no reasonable and scientific cost management in stages. Therefore, on the premise of ensuring the quality of construction projects, through effective management of the project cost, the construction cost can be controlled, the probability of over-budget and other phenomena can be reduced, and the project cost can be controlled within a reasonable range. Next, the article discusses the current situation of project cost management and the whole process of cost management.展开更多

In the development process of construction engineering industry, cost management plays an important role. It is the key to improve the economic benefits of the project and establish a good social image of the enterprise. Therefore, relevant personnel should clarify the important responsibilities of cost control in the whole process of construction project management, adhere to the basic principles of cost management, highlight the professional abilities, so as to improve the effect of cost management and better serve the development of the industry. Next, the article discusses the whole process cost control strategy in construction project management.展开更多

Of course, the cost control of engineering projects presents a strong technical, professional, which requires engineering consulting units to sum up the work experience, so as to ensure that the project cost control is more effective. Therefore, the whole process cost control of the project is mainly discussed in order to realize the fairness and fairness of the cost and to ensure the benefit of the project investment.展开更多
