“…Ultimately, legislative provision supports the deployment, adoption and enforcement of the Eprocurement at all levels within the construction industry and beyond if such is required. Further on, the future construction industry seems to embrace more environmental and digitalized technologies to tackle the current existing issues [15][16][17][18][19][20][21][22][23][24][25][26].…”

Construction Industry is evolving amid the fourth industrial revolution. Transportation, commerce, manufacturing and many other industries ripened the current technological advancement and are striving to utilise every development in the IT sector. The procurement of construction works is known to be very conventional and backward in the adoption of digitalisation. The construction industry's procurement and supply chain are blamed for the most inflated cost of construction projects, mainly attributed to a lack of transparency and trust between the industry stakeholders. This research explores the challenges of E-procurement adoption in the industry and identifies the potential opportunities for its usage. This investigation's data are acquired through interviews, and the data are analysed using qualitative content analysis. This study reveals compounding challenges (i.e., corruption and lack of commitment) that lead to the failure of such efforts in Nigeria and the potential prospects (i.e., transparency and efficiency). This study is essential in developing a more effective and transparent process of procurement so that the Nigerian construction industry is not be left behind in the fast-digitalising markets.

“…These innovative teaching methods, with the aim of strengthening the teaching offer and learning processes, are aimed at a greater understanding of the individual learning processes of the group dynamics that are triggered in a classroom. Specially with the increasing number of digital technologies in the construction industry such as use of AI to predict compressive strength of concrete [15][16][17][18], and other environmental automated systems [19][20][21][22][23][24][25][26][27][28][29], the need for VR integration becomes more obvious than ever.…”

Due to the importance given today to innovation, the education sector is evolving thanks digital technologies. Virtual Reality (VR) can be a potential teaching tool offering many advantages in the field of training and education, as it allows to acquire theoretical knowledge and practical skills using an immersive experience in less time than the traditional educational process. These assumptions allow to lay the foundations for a new educational environment, involving and stimulating for students. Starting from the objective of strengthening the innovative teaching offer and the learning processes, the case study of the research concerns the digitalization of MastrLAB, High Quality Laboratory (HQL) belonging to the Department of Structural, Building and Geotechnical Engineering (DISEG) of the Polytechnic of Turin, a center specialized in experimental mechanical tests on traditional and innovative building materials and on the structures made with them. The MastrLAB-VR has been developed, a revolutionary innovative training tool designed with the aim of educating the class in total safety on the techniques of use of machinery, thus reducing the dangers arising from the performance of potentially dangerous activities. The virtual laboratory, dedicated to the students of the Building and Civil Engineering Courses of the Polytechnic of Turin, has been projected to simulate in an absolutely realistic way the experimental approach to the structural tests foreseen in their courses of study: from the tensile tests to the relaxation tests, from the steel qualification tests to the resilience tests on elements at environmental conditions or at characterizing temperatures. The research work proposes a methodology for the virtualization of technical laboratories through the application of Building Information Modelling (BIM), starting from the creation of a digital model. The process includes the creation of an independent application, which with Oculus Rift technology will allow the user to explore the environment and interact with objects through the use of joypads. The application has been tested in prototype way on volunteers, obtaining results related to the acquisition of the educational notions exposed in the experience through a virtual quiz with multiple answers, achieving an overall evaluation report. The results have shown that MastrLAB-VR is suitable for both beginners and experts and will be adopted experimentally for other laboratories of the University departments.

“…With the green economy movement and other giant projects, researchers in the field of environmental construction must also put more focus on studying environmental alternatives for the existing nonenvironmental materials [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34].…”

Growth as an inevitable human nature roots even in our business operation. Private entities, similarly, in seek of expansion and maybe more influence over their area of expertise, decide to go public in a certain point of time. The timing to move from private to public, indeed, is a critical factor in the future success of the business. In the traditional capitalist structure of this move, small private companies, which are defined by the Australian Securities and Investments Commission as those entities with consolidated revenue of less than $50 million per year, choose between sellout to a parent firm or Initial Public Offering (IPO). Both options have their own advantages and disadvantages. Yet, they are both complex, highly regulated, costly, and frustrating which are truly major drawbacks for small entities. Failure to go public caused by these drawbacks results in death of small businesses and loss of jobs which is followed by terrible socio-economic consequences. To avoid the conventional frustrating publicity of the private firms, in this article, utilization of cryptocurrency as the modern financial instrument is discussed. Digital currencies enable fast transition, globalization, grassroot economy, and social justice.
