“…At the same time, BIM can help to reduce the rework amount, which plays an important role in cost management. However, it should be noted that BIM application also has the cost of complexity and implementation, because BIM can add to the complexity of the work and staff in various projects need to learn about BIM [32][33][34][35][36][37]. This is consistent with the study by Fanning et al [38] and Liu et al [39].…”

A number of bridge infrastructures are rising significantly due to economic expansion and growing numbers of railway and road infrastructures. Owing to the complexity of bridge design, traditional design methods always create tedious and time-consuming construction processes. In recent years, Building Information Modelling (BIM) has been developed rapidly to provide a faster solution to generate and process the integration of information in a shared environment. This paper aims to highlight an innovative 6D BIM approach for the lifecycle asset management of a bridge infrastructure by using Donggou Bridge as a case study. This paper adopts 6D modelling, incorporating 3D model information with time schedule, cost estimation, and carbon footprint analysis across the lifecycle of the bridge project. The results of this paper reveal that raw materials contribute the most embodied carbon emissions, and as the 6D BIM model was developed in the early stage of the lifecycle, stakeholders can collaborate within the BIM environment to enhance a more sustainable and cost-effective outcome in advance. This study also demonstrates the possibility of BIM applications to bridge infrastructure projects throughout the whole lifecycle. The 6D BIM can save time by transforming 2D information to 3D information and reducing errors during the pre-construction and construction stages through better visualisation for staff training. Moreover, 6D BIM can promote efficient asset and project management since it can be applied for various purposes simultaneously, such as sustainability, lifecycle asset management and maintenance, condition monitoring and real-time structural simulations. In addition, BIM can promote cooperation among working parties and improve visualisation of the project for various stakeholders.

“…With respect to the aspects of sustainable development systems thinking on HSR services [74][75][76], the efficient planning of HSR services can genuinely generate invaluable outcomes for other social, economic and environmental impacts [77,78], as follows: -Social impacts: reducing travel time between two cities, increasing the accessibility of attractions in the city, reducing the public transportation cost, allowing companies to hire specific labourers and trade in particular goods; -Economic impacts: increasing the economic via the transport and the logistic system (both domestic and international), immediately transferring products from the suburban areas, reducing shipping costs in the country as there is an alternative mode of transportation; -Environmental impacts: reducing the amount of CO 2 emissions in the air, reducing the amount of land use compared with the road and highway.…”

At present, many countries around the world have significantly invested in sustainable transportation systems, especially for high-speed rail (HSR) infrastructures, since they are believed to improve economies, and regenerate regional and business growth. In this study, we focus on economic growth, dynamic land use, and urban mobility. The emphasis is placed on testing a hypothesis about whether HSRs can enable socio-economic development. Real case studies using big data from large cities in China, namely Shanghai province and Minhang districts, are taken into account. Socio-technical information such as employment rate, property pricing, and agglomeration in the country's economy is collected from the China Statistics Bureau and the China Academy of Railway Sciences for analyses. This research aims to re-examine practical factors resulting from HSR's impact on urban areas by using ANOVA analysis and dummy variable regression to analyse urban dynamics and property pricing. In addition, this study enhances the prediction outcomes that lead to urban planning strategies for the business area. The results reveal that there are various effects (i.e., regional accessibility, city development plans, and so on) required to enable the success of HSR infrastructure in order to enrich urban dynamics and land pricing. This paper also highlights critical perspectives towards sustainability, which are vital to social and economic impacts. In addition, this study provides crucial perspectives on sustainable developments for future HSR projects.

“…Results showed that rail infrastructure maintenance extended facility lifespans and helped reduce carbon emissions. In this paper, specific greenhouse gas (GHG) emission estimation methods were introduced to reduce the uncertainties and providing reasonably accurate estimate (Kaewunruen et al, 2014(Kaewunruen et al, , 2015. The estimation methodology mentioned in this paper can aid in construction carbon emission estimation and give guidance of carbon emission calculation for the King's Cross station project.…”

The railway station is a primary asset of public transport systems and plays a crucial role in urban modernization. Most existing railway stations in the UK is historic and have been operated for many years. Maintenance and reconstruction are common concerns in the public railway industry, and clusters of information pertaining to this maintenance must be managed appropriately for effective outcome. Digital twin or BIM (Building information modeling) is a term frequently employed in the construction industry nowadays, because of its ability to provide wider and faster access to comprehensible and integrated information. A digital twin or a BIM is not only a tool, but also a process that can help to make changes in construction industry, which has remained unchanged for hundreds of years. This paper discusses a specific BIM application within the context of railway station buildings using a Revit-based simulation of construction work for King's Cross station in London. The paper highlights the adoption and transformation of 3D model of the King's Cross station building into a 6D building information model. The 6D model contains a time and cost schedule with carbon emissions calculation, and renovation assumptions using Revit. The outcome of this study can provide construction participants with reasonable guidance of BIM adoption on railway station projects that can be used for planning, designing, and operating an economic and environmental efficient construction project.
