So any disruption due to hazard event like earthquake can cause several direct and indirect damages. Direct damages can lead to the loss of equipments and qualified persons. Indirect damages can lead to inflation and loss of purchasing power. To deal with that situation, parameters that govern the vulnerability of building construction site have been identified. Using a MCDM （multiple criteria decision making） method, the priority order of these parameters has been set. Then a PVI （partial vulnerability index） and a GVI （global vulnerability index） are proposed. These indexes allow the classification of building construction sites according to their intrinsic vulnerability and seismic vulnerability respectively that is through the use of a given classification. Several Algerian building construction sites belonging to different seismic zones were considered in order to show the applicability of the method.展开更多

Nowadays, more and more project managers pay more attention to the construction progress and construction cost, but ignore the safety control problems in the construction process. In this paper, starting from the key points of construction site safety supervision of construction projects, aiming at the common problems in the practice of safety supervision, several optimization strategies are summarized for reference.展开更多

More and more local water conservancy and hydropower projects have started construction. However, due to the difficulty of construction, long construction period and harsh working environment, some safety accidents are easy to occur, and the construction risk is still high. Therefore, we should always put the improvement of construction safety factor in the first place, check, monitor and gradually eliminate all potential safety hazards on site, and try our best to improve safety. Based on this, this paper analyzes and probes into the identification of hazard sources in the construction site of water conservancy and hydropower projects and the related problems of prevention and control measures in order to promote the all-round development of Chinas economy.展开更多

At the same time, due to the long construction period, there will often be a relatively large number of participants. In addition, the involved construction steps are also changeable and complex, which often requires the support of a large number of professional equipment and technical schemes. Because the comprehensive management capabilities of construction enterprises are not the same, the overall performance is mixed, so many safety accidents will inevitably occur, seriously affecting the core interests of employees within the enterprise. In order to fully solve the limitation and influence of safety accidents and effectively eliminate potential safety hazards, we should focus on the analysis of on-site safety management and solve the limitation and influence of various problems, so as to lay a solid foundation for the safe and stable development of the construction industry. In order to ensure that the construction industry can achieve more effective development, this paper will focus on the analysis of common safety problems in the current construction site, and find corresponding solutions, in order to provide relevant reference for relevant units.展开更多

Based on this, if the construction enterprise wants to ensure the sustainable development, then it is necessary to strictly control the site construction technology management in the construction of the construction site, and effectively improve the overall effect of the professional technology of the relevant construction personnel and the construction schedule. At the same time, good construction site management can also effectively reduce the cost of the construction unit and effectively promote the overall competitiveness of the construction enterprise. However, due to the large scale of the construction project, in the face of a large number, there will be certain safety risks, if not paid attention to, is bound to bring a great impact on the quality of the construction of the project. Therefore, the construction of a perfect construction quality supervision system has a very important role in the development of enterprises. Next, the article mainly aimed at the present stage of China's construction site technical management of in-depth analysis and research, and in view of the existing problems put forward some effective measures to ensure the overall quality of the construction project, for the construction enterprise to establish a good image.展开更多
