Summary: As an infrastructure project, the cost and benefits of road maintenance should be measured through social costs. In order to fully consider user interests and make road maintenance decisions more reasonable, two types of user costs that may affect road maintenance benefits have been quantified through analysis of existing literature. At the same time, the impact of environmental issues on decision making in road maintenance should also be considered.

Summary: The Paris Agreement and the United Nation's 2030 Agenda for Sustainable Development are driving a global transition towards more sustainable, affordable, and reliable energy systems. This poses a challenge for the corrosion industry, as the development of climate-resilient energy systems and infrastructures requires considering the long-term behavior of structural materials, particularly metals and alloys. "Corrosion Challenges Towards a Sustainable Society" presents a series of cases that emphasize the importance of corrosion protection for metals and alloys in energy production, aiming to promote the understanding of corrosion science and raise awareness of the need for research and the consequences of corrosion in the public and political arenas.

Summary: Building fires, especially during operation and maintenance periods, are common and most risk factors are linked to human activities. Fire risk assessment is necessary to control and improve prevention, with methods like quantifying risk index and using BIM technology. Introducing assessment index systems and risk value calculation models can enhance firefighting abilities and utilize BIM technology effectively.

Summary: This paper proposes a BOM framework based on sharding blockchain (SBC-BOMF) to solve the storage limitation and scalability issues in the application of blockchain in building operation and maintenance. It considers the impact of event's priority and real-time on blockchain transactions and designs a priority-based transaction handling strategy for multi-level transactions. The experimental results demonstrate that the proposed scheme effectively solves the scalability problem, reduces storage overhead, and achieves efficient handling for blockchain transactions in BOM.

Summary: The electrochemical behavior of steel used for concrete reinforcement can be either active or passive. It remains passive as long as the concrete environment remains highly alkaline, but carbonation and/or chloride contamination can cause it to become active and corrode. This study proposes a boundary element method for solving 3D periodic cathodic protection problems, with a reduced computation cost through the application of acceleration techniques based on adaptive cross approximation.

Summary: The article analyzes the method of determining maintenance costs of buildings based on Polish legal regulations. The sensitivity analysis shows that the assumed number of product use cycles has the greatest impact, while the warranty period has the lowest impact. It was proposed to use Net Present Value (NPV) for calculations and extend the building's life cycle to 80 years to overcome the limitations of the method proposed in the Polish law regulations.

Summary: This study examined the factors influencing the implementation of BIM technology during the O&M phase of construction projects in Malaysia. The research collected data from 302 construction professionals through literature review, interviews, and surveys. The findings revealed a high level of familiarity with BIM technology among respondents, with most companies employing more than 15 BIM engineers. The lack of learning materials and equipment from academic institutions and the increased efficiency of data accessibility were identified as key factors requiring attention. A conceptual framework was developed based on the results to guide future research on enhancing the implementation of BIM software during the O&M phase.

Summary: This paper describes an optimal preventive maintenance policy and optimization method for operation parameters of a production line consisting of multiple execution units. By establishing the relationship between the reliability and operating parameters of the execution unit, as well as the relationship between the operating parameters and maintenance cost, the objective of minimizing maintenance cost and maintaining effective operating speed is achieved through a heuristic algorithm to derive the optimal parameters. Finally, a numerical example and simulation experiments are presented to validate the effectiveness of the proposed method.
