Abstract: “Code of valuation with bill quantity of construction works”(GB50500-2008)published in July 2008 proposes a new concept of “Bidding Control Price” instead of “base bid price”. This paper firstly introduces the calculation program of Bidding Control Price which is different from the calculation program of base bid price. The calculation method of material price risk changes greater and it is the focus of our discussion. Article probes into the impact of material price risk on project cost, applying Grey Forecasting Model to discuss a reasonable method of determining material price risk, which provides a new feasible solution to determine an appropriate cost of project. Article concludes with examples which show that different material price risks have great impact of project costs. This paper has some instructive significance for the calculation of project cost in new code.

Abstract: Construction claims are contractor's legitimate rights from contract. And it is also the legal means to maintain economic interests. The quality of claim reports comprehensively shows the level of claim management. This paper expounds the constituents of claim reports and their correlations. Calculations for financial claims and time claims are mainly analyzed and skills of making claim reports is analyzes too. This paper provides reference to claims management personnel.

Abstract: With Beijing subway Suzhou street station project, the composition of safety system for construction phase was studied. The safety responsibility of administrative department, technical branch, and operational department and construction personnel was clarified. The division and cooperative relationship were also analyzed. Meanwhile the construction techniques for shallow burial and dim excavation to improve safety performance for the whole project as well as surrounding environment under complicated city environment were discussed.

Abstract: Four factors which are connected with effectiveness of team learning were defined, and they were motivation of knowledge learning, ability of knowledge transfer and sharing, methods of knowledge learning and system of knowledge learning respectively. Evaluation model of team learning in expressway project was established. Based on this model, weights and values of each secondary level index were determined with Delphi method. Using the weighted average method, evaluation values of four first level indexes were calculated, which were drawn in radar chart. In order to seek the worst result, radar chart should be adjusted, and final evaluation result of knowledge learning was ascertained by calculating the minimum area of polygon. Taking YR expressway project as an example for positive analysis, evaluation and result analysis of team learning was carried out.

Abstract: In the field of engineering and construction, unqualified construction quality, time delays, cost more than expected phenomena to occur. Because of these characteristics such as its large-scale construction projects, long cycle, the production of single and complex, there is greater risk than the production of general products, the risk increases the difficulty of construction project management, operating costs and the possibility of potential losses, therefore, risk management emerged and become an increasingly important integral part of project management. In this paper, fuzzy analytic hierarchy be used to construction project risk assessment, and to order the sort of each risk in order to prevent significant risks. On an actual project - the new stadium construction in Weifang City risk management case study, the reduction of risk of project failure is expected, but also the project is hoped for other industries to provide some reference for risk management.

Abstract: Bidding evaluation is a complex but important decision making process for buyer to ensure the project accomplish smoothly. Bidding evaluation has 1) separation in commercial and technical tender; 2) subjectivity in weights allocation. In order to solve the problems, this paper sought to build a new bidding evaluation model with an indicator system, based on Project Management Body of Knowledge (PMBOK). Data envelopment analysis (DEA) was introduced to assess the rank. With an alternative secondary function, the model extended the application of DEA cross-efficiency method. Experiment with a practical engineering showed the new model yield stable bidding scores and demonstrated its applicability.

Abstract: Aiming at the safety management of the Beijing subway line 10 in the construction, the technical system research of safety management in the underground railway engineering construction were discussed including the objective management of safe production, field safety standards, the founding method for safety management system. The contents of responsibility system for safe production and the contents of safe-education and safe-inspection for workers were also studied. Safety precautions and Safe checkage standards were established during the railway’s tunnel construction.

Abstract: Construction induced vibration may cause damage of buildings, disturbance of occupants, and sensitive equipments in buildings surrounding a construction site. The prediction of the construction vibration risk is essential for making decisions before the determination of construction method. Previous methods focus on the prediction based on quantitative analysis. The framework of a new method using fuzzy logic to predict the construction vibration risk is proposed in this paper. This method integrates the knowledge and experience from experts and simulates the inference process of human brain using Mamdani fuzzy inference principle. It is a convenient and economical method when used to provide support for project manager making decisions in primary phase of project.

Abstract: Based on practical engineering, a training model that integrates the courses of engineering, and completes the whole process of project bidding by using all-dimensional simulation of engineering, can effectively bring learning actives closer to practical work, enhancing the cultivation of students’ professional and practical skills. When practical skill is promoted in teaching activities, the training model of professionals in architectural engineering is accordingly optimized, producing students that are better qualified for construction and management positions in future, and are competitive in job market and easier to adapt to theirs jobs.

Abstract: The article mainly introduced how the land auction in our country impacted the sell price of land, and through analysising the influence of the policy in 2006 and 2010 which called “limit house price , compete land price” to land auction, got that this policy may control house price and land price in a short time. But in the long run, selling the land through auction had some problems, and this policy had difficulty in setting the price and the quality of the house couldn’t be guaranteed. According to the above questions, it proposed that it should through transforming government’s function, reasonably determining house price and strengthening the quality supervision of “limited price house” to solve the present situation of overpriced.
