In metropolitan areas, when a highway underpass project is being planned to go beneath an existing railway corridor, there are a number of concerns that could have an impact on the project. For example, will the underpass construction impact the existing railway operations? How to maintain the construction safety in both rail and highway operations? This paper brings construction technology using I-girder systems to provide a solution for highway underpass projects constructing beneath the existing rail corridors. The I-girder systems have been proved as a reliable method for highway underpass construction without the interruption of railway operations. This type of I-girder systems has been widely used in several countries as a temporary “bridge” structure in support of dynamic rail movements during underpass construction. Depending on the spans of underpass structures, a contractor can decide the number of I-girder units to be assembled and installed on site. This paper describes the construction procedures of the I-girder systems installation and daily inspection processes. A case study is used to demonstrate the applicability of I-girder systems in ensuring underpass construction smoothly while maintaining existing railway operations in a safety manner. During the construction of underpass, the contractor encountered geotechnical issues that had a severe impact on the construction safety and the integrity of foundation. This paper further discusses strategies that were used to mitigate the potential building collapses and foundation failures. It is concluded the method of I-girder systems is capable of supporting railway dynamic movements during highway underpass construction.

Reduce Risk

In recent years, Taiwan launched railway reconstruction projects to promote urban renewal and rural development. As the area of reconstruction projects is adjacent to the railway in operation, there are hidden risks to construction personnel and safety of the railway operations. The composite pier engineering method can improve construction safety and reduce risk. This paper presents a case study and discussion on risk management to provide the lesson learn for reference.

Rule Based Approach

The kingpost was a vertical element that was used to support the structural strut in the deep excavation. The structural kingpost was commonly arranged by experienced engineers who used two-dimensional construction drawings. Thus, it was still time-consuming and error-prone. Currently, an available construction program has been developed to arrange the structural kingpost by identifying the clash problems in the 3D environment. However, they have a limitation for detecting the clash that was unable to visualize the concurrent clashes between kingpost and many underground structures. Then, the engineer cannot see all the clash incidents with each kingpost and move the kingpost to avoid the clashes successfully. Since the kingpost arrangement was still an inefficient practice that was limited in the visualization aspect, this research used engineering knowledge and advanced construction technology to detect and solve the clashes between kingposts and underground structures. The methodology used engineering knowledge of kingpost arrangement to develop the system modules by using a rule-based approach. Then, these modules were developed into the system by using visual programming of Building Information Modelling (BIM). To test the system, an underground structure from building construction was selected as a case study to apply the developed system. Finally, the finding of this study could overcome human judgment by providing less interaction in the kingpost arrangement and visualization improvement of clash occurrences in the 3D model.

Over Time

As a medium for delivering modernity, movie theaters have faithfully recorded the dialogue between modernity and local daily lives. In contrast to modern movie theaters, traditional cinemas are distinguished by their long history, through which they reflect the changing connotations and social construction of modernity over time. Based on detailed analysis of the historical and social characteristics of Nanguan cinema, a 100-year-old movie theater in Guangzhou, China, we reach the following two conclusions: first, shaped by local traditional culture, the practice of moviegoing localizes modernity with a distinctive grassroots feature that enlivens everyday lives; second, moviegoing at traditional theaters in modern metropolitan areas has further enriched the connotations of modernity by providing a nostalgic experience for audiences.

Project Lifecycle

Purpose – The purpose of this paper is to advance knowledge on the advantages of integrating safety earlier in the construction project lifecycle. Design/methodology/approach – A case study approach is used to collect data from construction sites in the USA, which performs poorly in construction safety and health, and Australia (AU), which performs well in construction safety and health. Qualitative data are collected to determine how and when safety is considered in the project lifecycle in both countries, and then the results are benchmarked to determine the benefits of addressing safety earlier in the process. Findings – Data show that addressing a potential hazard earlier in the project lifecycle has performance benefits in terms of the level of hazard control. Research limitations/implications – The processes that are identified as possibly explaining the performance difference are just based on qualitative data from interviews. Targeted research addressing the relationship between these processes and safety outcomes is an opportunity for further research. Practical implications – The case study data are used to identify specific processes that are used in AU that might be adopted in the USA to improve performance by integrating safety earlier into the decision-making process. Social implications – This paper highlights the advantages of integrating safety as a decision factor early in the process. Worker safety is not just an issue in the construction industry, and thus the findings are applicable to all industries in which worker safety is an issue. Originality/value – This paper advances the safety in design literature by quantitatively supporting the link between when a hazard is addressed and performance. It also links the results to specific processes across countries, which advances the literature because most research in this area to data is within a single country.
