Abstract: At present the construction enterprises in our country expand rapidly toward building collectivized operation and a series of development bottleneck problems appear, in which building human resources management is of great importance and plays a key role. The level of human resource management in China's construction field is in general backward. How to advance the level of human resource management through improving employee satisfaction is the key factor to human resource management in the construction industry. And employees’ satisfaction can be achieved in three ways: Firstly, perfect employee welfare system to increase the investment to employees; secondly, improve performance evaluation system to guide the staff professional development; thirdly, set up employee training and developing system to promote the establishment of learning organization.

Abstract: This study focuses on the risk management of international hydropower contracting projects. The approach of questionnaire has been used to identify risk factors, and statistical analysis software has been applied to carry out statistical analysis on the survey data to calculate and sort the comprehensive indexes of the levels of key risk factors, thus providing operable and guiding technological approach for the risk management of international hydropower contracting projects.

Abstract: Civil architecture energy conservation efficiency evaluation is a kind of multi-factors, multi-hierarchies and multi-criteria synthetic evaluation. Perfect civil architecture energy conservation efficiency evaluation indicators system and reasonably effective synthetic evaluation methodology are keys to do energy conservation efficiency synthetic evaluation. This paper is based on framing civil architecture energy conservation efficiency evaluation system, and uses fuzzy synthetic evaluation methodology to frame civil architecture energy conservation efficiency fuzzy synthetic evaluation model, in order to make the result of evaluation more objective and reasonable.

Abstract: The author tries to develop and implement a web-based Project Cost Integrated Management System (WPCIMS) in China. The targets, the Cost Breakdown Structure (CBS) and its code system, the functional planning, the framework and the technical index of the WPCIMS were presented firstly. Then, experimental implement of this developed system were put forward in 3 A/E/C project. Finally, an empirical interview survey targeting the project managers of the studied 3 cases was carried to estimate its implement performance. Results show that the acceptance and implement of the WPCIMS can significantly improve the performance of the project cost control, and successful implementation of the WPCIMS, in terms of leading to better outcomes for the A/E/C project, Coordination improvement among participators and Reduction of contract disputes, etc, is not simple a matter of introducing the system into an project organization. Instead, it must be associated with overall project management approaches such as a suitable organization mode, an appropriate system, the standard workflows, adequate personal trainings and even a coordinated project management philosophy.

Abstract: There is no precedent in China which supplies uniform drinking water for a city or a group of cities, thus to study drinking-water pricing for Wanlu Lake has realistic and application values. Firstly this paper analyses sensitivities of water prices and installation fees on drinking-water demand. And then based on constraints of net asset profit margins and debt service coverage ratio four pricing strategies are given. Finally, simulations are made and reasonable water prices are discussed for each strategy, which provides references for developing of the direct-drinking water project for Wanlu Lake.

Abstract: Owing to the increasing complexity in the construction safety management, integrating experts' knowledge and experiences to make appropriate decisions is a commonly used method. Decision making problem is the process of finding the best option from all of the feasible alternatives. In this paper, non-structural fuzzy decision support system (NSFDSS) was applied in the prioritization of evaluation criteria based on some additional advantages identified. Finally, a numerical example which was drawn from the national standard in China is used to illustrate the procedure of the proposed approach.

Abstract: The aim of this research is to investigate the risks in public relationships with different stakeholders in an EPC project overseas from the aspect of contractors. All types of relationships and the relationship risks lying in them are listed, risk responses are recommended correspondingly by putting forwards several major methods. Specifically, risks in contractors and owners are analyzed in this paper. The data collection instrument was an item sequence scored by 11 professors in Tianjin University who had comprehensive understandings about the stakeholders’ relationships in an EPC project abroad. Ways to response to these risks are also recommended by these professors. Chinese corporations undertaking the EPC projects overseas may utilize these findings to identify the risks in public relationships and adopt proper measures to avoid these risks to ensure a successful EPC project overseas.

Abstract: The integrative fuzzy set pair model, established by set pair analysis (SPA) and fuzzy hierarchy analysis, was introduced to pre-evaluation of security states in the construction stage. Two relevant sets, evaluation index and dangerous standard, were analyzed and calculated in terms of the identity, discrepancy and contradistinction[1]. The indices and weights were determined by Delphi and fuzzy hierarchy analysis respectively in order to establish the integrative fuzzy set pair model of construction stage. Finally, the model was applied to the case study of Shenyang sewage treatment plant and the results demonstrated that the method proposed in this present paper is satisfactory.

Abstract: Risk management is an important component of the project life cycle cost management and the project cost risk management system includes management objectives identification, risk factors analysis, risk identification, risk assessment, risk management and risk information feedback. The objectives of the project cost management can be successfully achieved through the life cycle cost risk management of various stages.

Abstract: When there are storey-to-storey relationships or construction storey by storey, to discuss the flow construction cycle time with technology intermission or organizing intermission time. When the category of the construction sections can meet the requirements of formula, i.e. , has included middle storey intermission in construction period calculation formula, there is not single item; When the category of the construction sections can not meet the requirements of formula, i.e. or , there should make single item in middle storey intermission in construction period calculation, at that time, the working team can not be continuous and the working surface can make maximum connection.
