Abstract: The quality of construction management is a complicated work, green evaluation should be carried out systematically analysis. Evaluation index system according to the factors affecting the constructions quality, the quality management system can divide into four indexes including staff, material, equipment and technology as factor layer. This system help evaluate construction management systematically and synthetically.

Abstract: The phenomenon of budgetoverruns is common in the construction projects. The lack of overall projectinformation is the important reasons of causing budget overruns. BIM, as a kindof highly integrated information model, will play a positive role in thebuilding life-cycle cost control. This paper points out the disadvantages oftraditional cost control method, introduces the influence of BIM on costcontrol in different stages of building life-cycle, and briefly describes the present situation and futuredevelopment of BIM.

Abstract: Social indemnificatory housing is in the construction of house of our country town with relatively particularity a type of housing, it is usually refers to according to the national policy and legal regulations, unified planning, by the government as a whole, to provide specific people use, and on this kind of housing construction standards and sales price or rent standard to limit, the social security function of housing. The paper USES data envelope analysis method, in order to hebei province various administrative city in January 2012 to August safeguard room construction progress data as the research object, analyses the related statistics and analysis, compare the city in hebei province administrative safeguard room construction progress, obtain the progress development not balanced result, among them, the individual administrative city obviously lag behind other locally administratered level. We hope that this paper to ensure room construction efficiency is evaluation provide guidance.

Abstract: Being the unshakably important component of constructional engineering management, safety management drew the attention of all construction enterprises. However, hidden dangers still remain in many building projects. This thesis analyzes these major safety problems in constructional engineering management and gives effective measures that should be adopted in constructional engineering management in order to avoid accidents in building projects by improving the safety management level of constructional engineering.

Abstract: The risk of project contracts is the uncertainty that exists alongside a contract. It is the pressing issue for contractors to prevent and control risks as the peculiarity of building projects brings about series of uncertain risks. By going through the management process of contracts for construction projects, this thesis analyzes the sources of risks and gives ideas and suggestions for designing effective measures to avoid project contracts risks.

Abstract: The engineering construction item has a period to grow, the complicated degree is big, invest a great etc. characteristics.Many risk factors exist in the process of the engineering Construction. It will influence engineering item smoothly progress If can not effectively work well to guard against in time. Therefore, it have important meaning to strengthen a construction engineering risk management work. This text will carry on certain analysis to each risk factor of construction engineering item, and inquire into further how science, effectively strengthen a construction engineering risk management to work, then promise engineering item construction smoothly progress.

Abstract: Beginning from the definition and cost of measure item fee, analyzes the significance of construction cost control of contestable measure items. Measures of cost control are summarized from five perspectives of specific construction plansformulation, materials, machinery, labor and management-with combination of specific projects, so as to provide reference for cost control in projects.

Abstract: The sci-tech novelty search is a kind of information consulting service, based on the manual and computer retrieval, using the method of comprehensive and contrast analysis, providing the objective facts for the novelty and advancement evaluation of research project approval, sci-tech achievement appraisal, patent application, technology consulting and other innovation activities. The sci-tech novelty search institutions have rich information resources, human resources, customer resources and brand resources to carry out innovative value-added information service. In this paper, we select some value-added information service modes which are suitable to carry out by the novelty search institutes, and make the contrastive analysis between traditional novelty search service and innovative value-added information service. Therefore we make some constructive suggestions for the sci-tech novelty search institutions to increase competitive intelligence service, specific information service, intelligence reporting service, and foreign enterprise credit investigation service basing on the traditional novelty search service.

Abstract: The sci-tech novelty search institutes have accumulated a large number of novelty search commissioned data, processed scientific and technical information, professional novelty search reports and other valuable information. The statistical analysis of the information mentioned above can reflect the characteristics of one regions sci-tech innovation activities from one perspective. In this paper, based on the information of novelty search projects accomplished by Beijing Municipal Institute of Science and Technology Information in 2007-2011, we make statistical analysis on the subjects of the novelty search projects, and obtain four hotspot research fields of Beijing municipal sci-tech innovation in nearly five years: electronic information, new energy and energy efficient, optical mechanical and electronic integration, resource and environment. Then the important research branches in each hotspot research field are figured out. And one typical sci-tech innovation case is given in each hotspot research field. At last, based on the analysis of novelty search projects, the hotspots in four research fields mentioned above are put forward for the researchers to reference and make new breakthrough.

Abstract: Because of its preventing reflection cracks on the base of the asphalt macadam, improving the high temperature stability and resistance to water damage ability etc, it is getting more and more widely used, but when ATB30 base construction and prone to aggregate segregation and compaction characteristics, combining entity Xu Ping south highway engineering research, puts forward the reasonable paving and rolling technology, effectively avoid the aggregate segregation, improve the degree of compaction, guarantees the construction quality and progress.
