This paper describes the assessment of the probabilistic risk of an accident formed in the process of designing a technically complex facility. It considers values of conditional probabilities of the compliance of load-bearing structures with safety requirements, provides an approximate list of significant errors of the designer and analyzes the relationship between the degree of compliance and the level of danger of errors. It describes and proposes for implementation the regulated procedures related to the assessment of the safety level of constructive solutions and the reliability of the construction process participants.

Abstract:  In recent years,with the rapid development of the construction industry, the new building structure system and the personalized building shape are constantly influencing people’s vision. The large-scale and complicated construction is a major feature of the development of the building structure.The innovation of the structure has increased the risk in the construction process and put forward new technical problems for the construction of the building structure. The feasibility of the construction scheme and the safety of the construction process should be fully guaranteed.In the environment of industrial upgrading, building information model BIM has been more and more applications. The traditional steel structure constructiontechnology has the problems of the complex structure of components, the large workload of information sharing and so on. It can solve this problem by using BIM modeling, visualization application and information management sharing application.BIM technology through the construction project decision-making stage, design stage and construction stage, can solve the traditional risk management in the stage, inefficient and passive wins and other issues.

As the rapid development of China’s national economy, China’s construction industry shows a rapid growth. Because construct project has the feature of large investment and long construction time, there are many unforeseen factors in the construction process. The project participants may face many risks. This paper firstly analyses risk factors of construction project, secondly describes the mathematical models—SVM, and then on the basis of the method builds the model of construction project risk prediction. Lastly it uses example to prove the feasibility of the model, and it also provides an effective method for the construction project risk management.

The construction project serves as one of the most important projects in the construction industry. The high cost and the particularity in the implementation generate high risks in the investment and construction process. Over the years, the development of construction project management methods has promoted the management of risk factors. This paper reviews the suggestions of risk management of follow-up audit in construction stage and evaluates its application in construction projects.

As one of the major projects, urban subway plays an important role in the city development. However, therere a lot of uncertain risks throughout the entire construction process, any improper handling may lead to serious safety accidents and incalculable property damage, so it is essential to take full concentration in the urban subway risk management. This paper divided risks that may encountered in the process of subway construction into three parts, and gave advices from four aspects so as to effectively prevent and mitigate the subway risk, thus ensure the achievement of the subway construction.

AbstractIntroducing the non-productive time (NPT) concepts in the 1960s was a necessity dictated by the ever-increasing cost and complexity of the oil and gas well drilling. The NPT definition stayed unsettled until two decades later, the definition converged toward its accepted current definition of “the time when planned or out-of-plans drilling-related activities do not add value to the operation objectives.” NPT as it is defined in drilling nowadays is a form of time waste or loss which adversely impacts the overall efficiency of the drilling operation. Since the 1980s, risk management (RM) has become a sound technique to evaluate operational losses or wastes of many resources, including time. This paper presents an attempt to couple RM techniques with NPT philosophy together with other concepts such as Systems Thinking, Synergy, Continuous Improvement, and Total Quality. These concepts and derived techniques suit well controlling the intolerable waste that shows up in the form of delay in operations and materializes into most of the undesirable costs of drilling. These concepts, adopted herein, were applied on data from 60 rigs which were used to drill 250 wells for a period of 1 year of operation. In all 19 types of NPT were considered. A Java software model was developed and used to express NPT as an undesired event with probability of happening, in order to follow with RM terminology. The probability levels (related to the NPT values) for each rig were then defined and further classified into the four familiar ranks and their colors as used in RM: Acceptable (green), Tolerable (yellow), Inadmissible (orange), and Unacceptable (red). A matrix was established for all NPT categories and for the 60 rigs and was then named Rig-NPT Risk Matrix. A maximum probability ceiling was established as a reference for unacceptable risks of all NPT categories and for all the 60 rigs. Finally, sets of risk control recommendations were proposed to minimize the NPT in order to improve rigs performance. The concept of NPT and the science of RM when integrated gave a new approach to minimize the drilling losses. Using NPT analysis coupled with risk management was used to indicate where to optimize exerted efforts in order to synergize improvement of overall drilling performance.

In the construction process of different integrated pipe corridors, there exist a large number of similar and reusable risk analysis results. In order to improve the efficiency of risk analysis and the efficiency of dealing with accidents in the process of construction management of integrated pipeline corridors and systematize the fragmented risk analysis knowledge, this paper will build ontology-based knowledge for risk response in integrated pipeline corridors. This ontology knowledge base can not only standardize and informatize knowledge through the definition of knowledge attributes and classification of knowledge, which can help reuse risk management metaknowledge at different levels and greatly improve the efficiency of risk management, but also reason out the risk-causing mechanism and response strategy of new integrated pipeline corridor risk through the similarity between risks and the correlation between risk-causing factors, so as to realize the repeated application of risk knowledge.
