BIM-based digital platform and risk management system for mountain tunnel construction

During the construction of mountain tunnels, there are often various intricate and mutable potential hazards, the management and control of which are crucial to ensuring the safety of such construction. With the rapid advancement of engineering information technologies, including Building Information Model (BIM), the internet, big data, and cloud computing, dynamic management of mountain tunnel construction will inevitably become a prevailing trend. This paper proposes a new digital approach to realize the informatization and visualization of risk management in mountain tunnel construction, by combining monitoring measurement with advanced geological prediction based on BIM technology. The proposed approach suggests a BIM-based digital platform architecture for mountain tunnel construction, which is comprised of five layers—basic, model, data, application, and user. The integration of these five layers can realize risk management information during the construction of mountain tunnels. In addition, a set of dynamic risk management systems, including risk monitoring, identification, and assessment, can be established based on the digital platform. The digital platform and dynamic risk management system proposed in this paper have certain advantages in the construction of mountain tunnels, providing a new and significant way for the management of safety risks in such construction projects.

Big Data Impacting Dynamic Food Safety Risk Management in the Food Chain.

Foodborne pathogens are a major contributor to foodborne illness worldwide. The adaptation of a more quantitative risk-based approach, with metrics such as Food safety Objectives (FSO) and Performance Objectives (PO) necessitates quantitative inputs from all stages of the food value chain. The potential exists for utilization of big data, generated through digital transformational technologies, as inputs to a dynamic risk management concept for food safety microbiology. The industrial revolution in Internet of Things (IoT) will leverage data inputs from precision agriculture, connected factories/logistics, precision healthcare, and precision food safety, to improve the dynamism of microbial risk management. Furthermore, interconnectivity of public health databases, social media, and e-commerce tools as well as technologies such as blockchain will enhance traceability for retrospective and real-time management of foodborne cases. Despite the enormous potential of data volume and velocity, some challenges remain, including data ownership, interoperability, and accessibility. This paper gives insight to the prospective use of big data for dynamic risk management from a microbiological safety perspective in the context of the International Commission on Microbiological Specifications for Foods (ICMSF) conceptual equation, and describes examples of how a dynamic risk management system (DRMS) could be used in real-time to identify hazards and control Shiga toxin-producing Escherichia coli risks related to leafy greens.

On the impact of airfield pavement irregularities on the resource characteristics of aircraft operated in the Far North and the Arctic

Pavement roughness as well as the bearing capacity and the runway friction coefficient are important aspects of flight safety maintenance. The modern Russian and international requirements to operators of airfields and aircraft imply the development and use (by fixed base operators) of the Flight Safety Management System (FSMS), which represents a dynamic risk management system based on the principles of the Quality Management System (QMS). In terms of flights safety risk management, both airfield and aircraft operators need to take into account hazards related to the condition of airfield pavements, assess and, if needed, minimize the respective flight safety risks. Currently, there are almost no adapted models to assess changes in the irregularities of artificial airfield pavements in the Far North and Arctic, which would make it possible to assess their integrated impact on aircraft operated in the regions of extreme climatic conditions. In this connection, the conducted review and analysis of the existing methods and algorithms for the assessment of airfield irregularities provided a new view of the problem of flight safety maintenance in the areas of airfields located in the Far North and Arctic. Based on this, we determined the most significant hazards, which may damage aircraft, and provide recommendations on how to reduce the negative impact of airfield pavement condition on aircraft operation.

Risk management of coastal water safety for recreational activities: The case of Taoyuan coast

To reduce drowning fatalities and health damage during recreational activities in coastal waters, this paper proposes a dynamic risk management system. Based on the operational definition of risk management, potential risks of coastal recreational activities are first identified as surfzone hydrodynamic and water quality. The safety criteria for each factor are discussed accordingly. The depth-velocity product is adopted to evaluate hydrodynamic safety. Salinity is adopted as a proxy indicator, which could be monitored in real-time, of Escherichia coli colonies in order to avoid the 18–24 h delay for cultivation. Then, technologies for surfzone hydrodynamic and water quality monitoring are developed and implemented as the basis for real-time risk assessment.This system is tested on the north-western coast of Taiwan. The results are discussed as a case study. The results from drifter cluster and miniature wave buoy for mapping the current and waves demonstrates a rotating eddy induced by tidal current. The range of safe water areas could be clearly marked. By applying this dynamic risk management system for coastal recreational activities, an early alert can be provided with the hope to reduce drowning.

Risk Analysis of Integrated Pipe Gallery PPP Project Based on the Analytic Hierarchy Process

As a public infrastructure for integrated construction, the integrated pipe corri-dor can extend the service life of the road and save the urban ground space [1]. Rational distribution of integrated pipe corridors provides a strong guarantee for the sustainable development of the city [2]. In recent years, the integrated management of the corridor government and social capital cooperation (PPP) has been widely used in China, in the integrated pipe gallery PPP project, high-speed under the development situation, problems such as out-of-control design in the early stage and loss of trust during the construction period are frequent. Contractual disputes caused by these problems, government repurchase, project suspension and other risks damage the project benefits, which seriously violate the original intention of the project [3]. PPP projects are characterised by long-term, variability and complexity. Risks are more difficult to control than conventional projects. It is a need for a dynamic risk management system that can effectively prevent and control the occurrence of risks, accurately assess risk factors and ensure the protection of risk management.

Study of dynamic risk management system for flammable and explosive dangerous chemicals storage area

In order to improve the ability of emergency management for storage area of dangerous chemicals, a framework of risk management technical system about the flammable and explosive dangerous chemicals was proposed. Combined with the dynamic changes of dangerous sources, risk analysis for storage area of dangerous chemicals was conducted based on the Bow-Tie model. Dynamic hazards analysis method and classification system were established based on Set Pair Analysis, updating results in real time with the storage capacity and accident characteristics. Integrating with the GIS, Internet of Things, detection and sensing information technology, a dynamic security monitoring system was proposed. Based on the database technology, the emergency decision support system of dangerous chemicals was made, including storage date, emergency resource, emergency plans, information of risk, etc. Using the dynamic risk management system, it can effectively achieve the goal of dynamic supervision, risk identification, real-time monitoring as well as assisting the emergency decision making of dangerous chemicals in the whole life cycle. All models are comprehensively composed of the framework of dynamic risk management system, including identification, classification, assessment, supervision and emergency management.

Multiphase Risk-Management Method and Its Application in Tunnel Engineering

For a better understanding of risk management and the optimization of risk mitigation, a multiphase risk-management method is proposed in which the assessment of risks is divided into two phases: the initial risk phase and the secondary risk phase. The initial risk phase is used for risk evaluation at the beginning of a project and can be quantified by the combination of probability and loss. If the initial risk is not acceptable, risk-mitigation measures are evaluated and the most appropriate measure will be adopted. The secondary risk phase involves identifying risks after implementing the selected mitigation measures for the initial risk, and the mitigation costs are also included. Obviously, the secondary risk must be lower than the initial risk. The task of a tunnel engineer is to select mitigation measures that result in the lowest secondary risk. During project execution, environmental factors may change, and deviations from the original design assumptions may take place. These phenomena have a knock-on effect on the risk profile, and a timely reevaluation of the risk scenario becomes necessary. Therefore, it is further proposed that the two-phase risk-evaluation process be extended to infinite phases. The novelty of the proposed method is characterized by its combination of a dynamic risk-management system and a timely reassessment of new risks, and the continuous tracking of risks until they are negligible. Finally, a relevant example of risk management using the proposed method is illustrated, in which the most appropriate and economical risk management was achieved, and the established objectives of the construction quality and timeline were ensured. This multiphase risk-management approach can be applied to tunnel engineering as well as other engineering fields.
