Saudi Arabia recently established public–private partnerships (PPPs) in order to increase the private sector’s involvement in financing and providing affordable housing. However, the successful implementation of the PPP for affordable housing in Makkah necessitates careful consideration of possible barriers. As a result, the purpose of this study is to assess the critical success factor of the PPP and to introduce a housing affordable model for the low-income community. The survey method was used in the study to determine the critical success factors of PPP for affordable housing provision, with participants from both the private and public sectors. Using a five-point Likert scale, respondents were asked to rate the degree of influence of prospective critical success factors of PPP. The data gathered was analyzed using statistical tools. The study’s findings describe the critical success factors of public–private partnerships for affordable housing and establish the critical success factors of the PPP model for affordable housing in Makkah. As a result, determining the critical success factors and suggesting a way forward for the government to effectively provide affordable housing for low-income groups, as has been successful in other parts of countries such as the United Kingdom, Australia, and India, among others.
The construction industry is one of the main economic sectors that contribute significantly to social and economic development. However, the lack of skilled labour is one of the factors affecting the success of projects in the construction industry. Skilled labours are the potential for enhancing overall delivery of construction projects to achieve sustainability. Building and construction industry in Makkah has continued to respond to shortages of skilled labours. Hence, the purpose of this study is to evaluate the importance of factors influencing the shortage of skilled labours from the perceptions of construction practitioners. In order to achieve the aims and objectives of this study, the quantitative descriptive method was adopted for this research study, and data for this study was collected through a stratified random sample of construction practitioners in Makkah. Data were first analysed by way of Analysis of Variance (ANOVA), followed by Relative Importance Index (RII) for ranking comparison among the construction practitioners. The results of RII indicates that the significant factors influencing the shortage of skilled labours in Makkah include delay in salary payment, low wages structure, lack of motivation system, health and safety issues on construction sites, lack of job security, bad relations between skilled labours and management team, poor living conditions, Slow recruitment of skilled labours, restricted government regulations, and exposure of climate conditions. The findings revealed that the factors rated are required for organisational performances which are essential in achieving sustainable building and construction in Makkah.
To reap the most advantages while maintaining the functioning of residential building projects, sustainability concepts should be included at all stages of the construction decision-making process. This research identified and investigated the barriers to the employment of cyber technology in residential construction projects in order to ensure their long-term viability. Prior research identified cyber technology barriers, which were then contextually explored using a questionnaire survey in the Nigerian construction business. An exploratory factor analysis (EFA) revealed that cyber technology hurdles may be classified into five constructs: knowledge, government, culture, project nature, and regulations. The barriers model was also built using partial least square structural equation modelling (PLS-SEM). According to the findings, project-related constraints were key impediments to the implementation of cyber technology. The findings of this study might serve as a guide for decision-makers in Nigeria’s construction industry looking to decrease costs and boost sustainability via the use of cyber technology.
The Saudi Vision 2030 is a program of change management on a national level driven mostly by the use of digital technology. The implementation of building information modelling (BIM) is part of this change, and there is general agreement that its use improves the productivity and quality of the architecture, engineering, and construction (AEC) industries. Despite its extensive construction projects, Saudi Arabia has only recently planned for BIM. Several conditions must apply before it is successfully implemented. While the literature has identified the factors critical to its success and the barriers to its adoption, few studies have rated these factors in terms of their importance and their contingent impact. Furthermore, the interactional relationship between the factors has rarely been investigated. As a result, an interpretative structural model (ISM) was conducted to establish a hierarchy of variables, while accounting for the dynamic interaction between each. For factor selection, the matrix-based multiplication applied to a classification (MICMAC) method was utilized. Therefore, awareness of BIM and sustainability benefits are expected to be the most important variables in acceptance. Furthermore, the dynamic method is gradually shifting from bottom-down to a combined effect of top-down and bottom-up leadership.
