Design-build (D-B) had been applied in many advanced countries because the delivery method improves construction project success. While several megaprojects in Malaysia have adopted D-B, it is still uncommon in the local construction industry. Therefore, understanding the key drivers that are affecting the acceptance or rejection of D-B is crucial. However, that information is lacking in the existing body of knowledge. Thus, this research addresses that issue by identifying the key drivers for adopting D-B in the Malaysian construction sector from the standpoint of the core project parties (e.g., project clients, consultants and contractors). Questionnaire survey data from 111 professionals with D-B experience were analysed using inferential statistics, including t-test and analysis of variance (ANOVA). The outcome shows that the key drivers for industry practitioner in Malaysia for adopting D-B are: (1) "Maximise the use of resources between project team members", (2) "Sharing of expertise (design and technical) with project team members", (3) "Well-organised project team structure", (4) "High success rate" and (5) "Dispute prevention during the construction stage". Also, there are no significant differences found in the drivers between different geographical regions and project parties. Based on the investigations, this study adds to the current assortment of information in capturing the key drivers and providing an in-depth understanding of the underlying components for adopting D-B in Malaysia. Researchers and industry practitioners can use the findings to enhance the level of D-B adoption strategically.

According to some factors such as participation, interactions, identification and security, Iran's traditional bazaars are good examples of social sustainability. In fact, bazaars are not considered as merely an economic environment but also an environment for many social activities due to their status and their location in the important environments and centres of the city, and the significant role and social status of market's businessmen in the city. However, in the modern industrial era and with appearance of new urban elements, it can be observed that many spaces for commuting and many urban traditional environments took important social-cultural functions. Under these circumstances, this research used the descriptive analytical method to focus on evaluating the environments of persistent traditional social business centres in order to achieve persistence in modern social business centres through evaluating and studying the historical background of business centres, urban services and traditional elements that form them.

If disputes are not resolved promptly, they tend to become prolonged and escalated, creating a more complicated and less manageable scenario. Therefore, in this study, we formulated a mechanism for dispute resolution in the Iranian construction industry based on alternative dispute resolution methods. The formulated mechanism could aid disputing parties in the construction industry to settle their disputes more effectively and enhance dispute resolution methods in construction standard forms. To achieve this goal, we collected qualitative data using semi-structured interviews with 30 experts who were selected via purposive sampling method. We used MAXQDA software to manage and organise complete interview transcripts and facilitate the qualitative data analysis process. The proposed mechanism and guidance were finally validated using the survey questionnaire. Negotiation has equal potential for dispute resolution with different sources, and it is recommended as the first step in dispute resolution with any source. According to the results, we recommend a three-step resolution mechanism as follows: negotiation, a method based on sources of disputes and a hybrid method of adjudication and arbitration (Adj-Arb), as the appropriate mechanism for dispute resolution in the Iranian construction industry. Replacing arbitration with Adj-Arb in construction standard forms will have satisfactory results in resolving construction disputes and reply to growing criticism that arbitration is becoming more like litigation.

The importance of digital skills diffusion in fostering the architecture, engineering and construction (AEC) industry has been highlighted for more than a decade. The extent to which this objective can be achieved depends on several factors. An augmented building information modelling (BIM) adoption stems from, but is not restricted to, government policies and initiatives. This study aims to assess the diffusion of digital skills, specifically through BIM adoption and to establish feasible strategies for such adoption within the Italian AEC industry, taking into account institutional, organisational and project-related factors. This purpose is achieved through an initial investigation of the most significant hurdles in BIM uptake and various BIM-promoting policies adopted at an international level. Moreover, a rigorous review of recent developments in the diffusion of innovation theory is presented. Based on findings and combining the experiences of various authors in BIM-related research an exploratory online survey was conducted, resulting in identification of the clients' lack of knowledge as the most critical challenge to BIM adoption in the Italian AEC industry. Following this finding, the study suggests five strategies to leverage BIM benefits to their full extent, to increase the perception of BIM benefits and to bridge the current gap between the industry and academia.

This article seeks to determine whether privacy has a moderating effect on the relationship between residential livability and life satisfaction among low-income groups in Dutse, Jigawa State, Nigeria. The study utilised a quantitative research design, whereby descriptive and inferential analyses were employed. This was achieved through a wellstructured questionnaire administered to low-cost housing residents in the state. The data were subjected to descriptive analysis using the Statistical Package for Social Science (SPSS) software and structural equation modelling (SEM) using Analysis of Moment Structures (AMOS). The results indicated that about 73.4% of the residents experienced a low level of life satisfaction. The findings from the SEM showed that the moderating effect of privacy in the relationship between the dwelling unit and life satisfaction was good. Meanwhile, privacy was not a moderator in the relationship between social environment and life satisfaction. Finally, the article revealed that the residents' life satisfaction could be improved if dwelling unit features and privacy were considered in the low-cost housing design. Practically, the study serves as a blueprint for government policy in designing low-cost housing in the future.

There is still limited research that investigates emotional intelligence in the context of the real estate sector in China, despite the rapid growth of the industry. Furthermore, there has been an exponential increase in the number of Chinese students studying overseas. Underpinned by these tendencies, this research investigates the levels of emotional intelligence of overseas and local graduates in the real estate sector in China. Data were collected using a survey of 140 employees and semi-structured interviews of four human resource managers in six Grade One state-owned real estate companies in China. The findings suggest that emotional intelligence influences the levels of interpersonal skills, represented by communication skills and teamwork behaviour. However, there is no difference in the levels of emotional intelligence between overseas and local graduates, suggesting that there are other factors that influence emotional intelligence development. Overseas graduates also seem to have greater difficulties than local graduates from elite universities to find jobs in the real estate sector. This suggests that international study experience is no longer adequate; instead, various contextualised interpersonal skills are needed to meet work demands in China. Developing emotional intelligence has been found to promote success across cultures and is a way to meet the demands of today's work environments in the real estate industry in China.

The diffusion of building information modelling (BIM) has remained slow and the search for a solution to the problems that prevent technology acceleration continues. Although, there is strong evidence that user resistance is a major factor in delaying the adoption of new technologies, little attention has been paid to the drivers of BIM use in literature. Besides, majority of the studies on organisational barriers focus on large firms, despite strong emphasis laid on increased collaboration in the BIM. In the current study, the drivers of and barriers to BIM adoption and implementation are explored at both individual and organisational levels through a survey conducted on 905 industry professionals from the Turkish construction industry. This study further explores differences between groups of firm size in embracing BIM technologies to assess the extent and presence of digital divide. Results reveal that professionals place more value on performance enhancing factors rather than social influence for the adoption of BIM, indicating the role of improved performance as a driver for BIM. The most prominent barriers, on the other hand, appear to be related to the availability of expertise and skills, a problem that seems to exist not solely within companies but also further down the supply chain. Policymakers seeking to disseminate BIM use may address these concerns and consider these insights to revise policies and incentives.

Poor management practices of road transport assets posed a challenge to the sustainable development of the transport system in developing countries like Nigeria. Studies in the past focused mainly on the performance of road construction process. However, few studies have evaluated the effect of the fourth Industrial Revolution (4.0IR) on the road transport assets in developing countries such as Nigeria. The current study aimed at assessing the effect of the 4.0IR towards improving the management practice of road transport assets. Survey instruments were administered to project and facility managers in the Nigerian road construction sector of the economy using a proportionate random sampling technique. Partial least square structural equation modelling was used for data analysis utilising the Warp 7.0 partial least squares-structural equation modelling (PLS-SEM) software algorithm. The software calculates p-values with WarpPLS based on non-parametric algorithms, resampling or stable algorithms and thus does not require that the variables to be normally distributed. The study concluded that the 4.0IR drivers have a moderate effect change on the management practice of road transport assets in Nigeria at the moment. The findings imply that management of road assets in Nigeria would moderately improve due to the 4.0IR technologies resulting in transport, safety and general efficiency and effectiveness of road networks in Nigeria. The study identified the 4.0IR drivers to include robotics, mobility, virtual and augmented reality, Internet of things and cloud computing, machine learning, artificial intelligence, blockchain, three-dimensional (3D) printing drones that are built with an attached 3D printer (the drone hangs a 3D printing nozzle that has fed plastic, concrete mix or other material from a tube connected to the top of the drone's printing path that precisely plotted by software, for a promised printing accuracy of 0.1 mm) and digital engineering. This study emanated from the government reports and past studies in the area of road transport asset management practice which the study investigated the major causes of poor practices and assessed the effect of the 4.0IR on the practice.

Construction disputes are inevitable. They often arise between project stakeholders for numerous reasons and to resolve them, construction professionals adopt various dispute resolution methodologies. This study aims to identify the role of building information modelling (BIM) in mitigating such disputes and addresses the legal barriers faced by the architecture, engineering and construction (AEC) industry while adopting BIM. The study reveals that disputes can be mitigated and managed efficiently with the intervention of BIM, as BIM offers various designing, planning, estimating, collaborating and controlling features. The benefits of BIM are impressive and exceptional; however, it comes with some legal issues that are first clarified and addressed with the support of a literature review and later validated through interviews with industry professionals. Dispute resolution, contractual arrangements, design responsibility, intellectual property (IP) rights and a lack of standardisation are identified as substantial concerns when adopting BIM. Thus, a strategy is proposed to manage these legal issues that entail the adoption of the appropriate contract suite, the formation of a common data environment (CDE) and the establishment of a firm BIM execution plan (BEP). Workshops, training sessions and seminars are also recommended to educate the industry with BIM features as it brings about the second revolution in the AEC industry.

The gradient of height in buildings is the most common way to prepare a comfortable environment and to increase wind forces around the buildings. This study assessed various design choices that enable architectural buildings to have different heights using computational fluid dynamics (CFD) simulation to analyse wind conditions. Nonetheless, wind effects may create uncomfortable zones around high buildings and may be hazardous for pedestrians in open spaces. As such, this study looked into pedestrian level wind (PLW) to enhance the wind environment of buildings in Iraqi climate. Wind characteristics may create a range of disturbance levels that affect pedestrian areas. Iraqi residential buildings were taken as case study to quantitatively analyse the outdoor buildings at PLW, so as to generate some ideas and solutions between CFD simulation analysis and architectural design to yield an optimal model.
