Sustainability in the Civil Construction Sector Supported by Industry 4.0 Technologies: Challenges and Opportunities
The civil construction sector is under pressure to make construction processes more sustainable, that is, aligned with economic, social, and environmental sustainability. Thus, the research question considers: How do Industry 4.0 Technologies help civil construction face challenges and identify new opportunities to become sustainable? The general objective of this work is to offer a current overview of publications that associate the civil construction sector; Industry 4.0 Technologies and sustainability, and identify the challenges and opportunities of the Industry 4.0 Technologies set to contribute to sustainability achievement. The research method was a bibliographic review combined with bibliometric analysis in SCOPUS databases. The results show that civil construction faces the challenge of reducing the consumption of natural resources, ensuring safe work, and optimizing processes, especially handwork. However, the insertion of Industry 4.0 Technologies into civil construction has allowed sensors, robots, modelling and simulation systems, artificial intelligence, and drones to have their productivity, efficiency, safety, strategic and environmental management enhanced. Furthermore, Industry 4.0 Technologies can contribute to civil construction through innovative, sustainable, and technological solutions focused on the flow of work, which can provide growth through the balance of costs/benefits in the management of projects and works. Thus, it is expected that this article will contribute to discussions around the possibility of construction becoming sustainable with the support of Industry 4.0 Technologies.

Challenges for the implementation of sustainable construction practices in Libya
Sustainability is considered to be a central part of every global policy change because of the likelihood of negative effects of particular policies on the already endangered environment and on society. Whilst sustainability is receiving significant attention in construction sectors in developed countries, this seems to be less true for developing countries. Thus, this study explores the challenges faced by the construction sector in one such developing country, Libya, in integrating sustainability practices into its common scope of activities. The study adopted a mixed research approach consisting of a questionnaire survey and expert interviews. Completed questionnaires (134 No.) were analysed using statistical techniques. The findings from the survey informed the topics for the interviews with 10 experts where the collected data were analysed through content analysis. The outcomes of the research explained that the awareness of sustainability in construction was weak in the practice of the Libyan construction sector. Additionally, the failure of supporting institutions to create an effective application of sustainability guidelines, lack of stricter legislation, building codes or standards were also found to be major challenges. The study contributed to knowledge by providing a better understanding of sustainability and clarified the main challenges faced by the stakeholders and which they have to consider in order to improve sustainable construction in Libya. The practical implications of the study include the strategies identified to avoid or minimise the challenges and their consequences.

Risks of implementing sustainable construction practices in the Nigerian building industry
This study assessed the risks level associated with implementation of sustainable construction practices through a questionnaire survey distributed to 256 building professionals in Nigeria. It identified 47 risk factors with different likelihood of occurrence and magnitude of impacts. A quantitative risk analysis result based on mean value method and risk prioritisation number showed that the three top-ranked risk factors with highest likelihood of occurrence were unavailability of sustainable materials and equipment, more complex and unfamiliar construction techniques and processes, and high initial sustainable construction costs; whereas the three top-ranked risk factors with highest magnitude of impacts were high initial sustainable construction costs, poor and inefficient communication among project participants, and high cost of sustainable materials and equipment. The criticality index result identified 23 critical risk factors which mostly related to knowledge and awareness, cost, regulatory framework, building materials and socioeconomic issues. However, the Wilcoxon Signed-rank test result indicated that there is significant difference (z = -3.207, p<0.001) between the likelihood of occurrence and magnitude of impacts of the risks factors associated with implementation of sustainable construction practices in Nigeria of which the effect was moderate (r = 0.468). Furthermore, the study revealed that there is no significance difference in the risk level of the risk factors associated with implementation of sustainable construction practices based on the respondents’ roles (p>0.05). The study, therefore, recommended for training of construction practitioners in the multi-risk management approaches and increasing awareness through education on sustainable construction concept for building industry stakeholders. It further recommended for developing of new sustainable and affordable building materials through research institutes like Nigerian Building and Road Research Institute (NBRRI) with appropriate regulatory and policy frameworks for successful sustainable building projects.

Carbon Emissions of Construction Processes on Urban Construction Sites
For Europe to achieve “climate neutrality” by 2050, emissions from all economic sectors must be reduced to the absolute minimum. In addition to changes in raw material extraction and building material production, the construction industry must embrace emission-free construction sites. The present paper suggests a method to calculate carbon emissions on construction sites by defining all fuel-consuming processes while relying on established European standards. A set of system boundaries is defined to single out emissions that occur in the construction industry sphere. These definitions are essential to calculate savings through the entire construction process. This method is subsequently used to assess the carbon balance of four exemplary construction sites in Austria, which cover the total span of the construction life cycle. Results show that the largest share of emissions is attributed to transport during the construction of new buildings, followed by emissions from demolition and building processes.

A sustainable–lean implementation methodology: a catalyst for sustainability enhancement of high-rise residential projects
PurposeThe importance of lean and sustainability integration in sustainable construction (SC) has been extensively studied. However, a practical and thorough implementation methodology addressing the project life cycle phases is still inadequate. The present study has developed a novel phase-wise sustainable–lean implementation methodology for high-rise residential projects.Design/methodology/approachThe current study has identified the 50 direct conceptual interactions between 11 lean principles and 11 sustainability criteria encompassing 44 different attributes covering 174 sustainability actions. A panel of nine experts validated these interactions, and 50 integration vectors were proposed addressing different phases of the project life cycle of high-rise residential buildings. The experts also analysed the identified integration vectors for their current and likely future implementation in high-rise residential projects.FindingsThe interactions between lean and sustainability principles led to the development of a phase-wise implementation methodology. The experts' survey responses on the current level of implementation revealed that 40, 32 and 28% of integration vectors were implemented rarely, sometimes, and frequently, respectively. For likely future implementation, 28 and 72% integration vectors were reported as very likely and extremely likely to implement, respectively. This survey response highlighted the usefulness of identified integration vectors for enhancing the sustainability of high-rise residential projects.Originality/valueThe proposed sustainable–lean implementation methodology acts as a comprehensive guideline for implementing a lean approach to achieve the objectives of SC in high-rise residential projects. This may facilitate the transition from conventional to sustainable building practices using a lean approach.
