The construction industry is responsible for the infrastructural and physical development of nations and plays a pivotal role in determining economic equilibrium of nations of the world; hence, there is a need for constant evolving of advanced ways of carrying out construction operations. The concept has led to the evolution of Construction 4.0, which entails harmonizing disruption in technological applications to enhance construction productivity. The study, therefore, provides an attempt at evolving an enhanced approach to improve construction processes and resource management through application of lean construction and Industry 4.0. The purposive sampling method was used in this study to collect data. The data collection instrument consists of a structured questionnaire designed in a Likert scale of 1 to 5 distributed to 100 construction professionals through an online method that is actively involved in construction operations. The following parameters were censored and profiled, while the results are in tables and charts. The parameters include areas of lean thinking that could enhance Construction 4.0, areas of disruption in Industry 4.0 that influence Construction 4.0 advancement and parameters for practical integrating of lean thinking approach and Industry 4.0. Additionally, the influence of Industry 4.0 in technological development for the construction industry, disruptive innovation of Industry 4.0 and gains towards Construction 4.0. Furthermore, the relevance of Construction 4.0 in construction productivity, the importance of Construction 4.0, industrial application drivers in achieving Construction 4.0, future of Construction 4.0, achieving automation goal in construction and performance expectation of lean thinking and Industry 4.0 in the construction industry are found necessary. Simple percentage, Spearman rankings, Chi-square test, Student-T test, Mann–Whitney-U test and Relative Agreement and Importance index are the tools used to process the data. The study discovered, among others, the veracity of contingency approach in harnessing attributes of the lean thinking concept and disruptive applications in achieving Construction 4.0. The study recommends the application of the hybrid model suggested in the study as a guide to deployment of an application that could help in industrial productivity.

This data article explores the factors that contribute to maintaining steady cost projection on construction projects. The data was obtained using structured questionnaire designed in Likert scale. The responses were solicited from category of construction practitioners. Simple random sampling was employed in the distribution of the questionnaires to the respondents. Data samples were analysed using severity index, ranking and simple percentages. The analysis of the data brought to fore some important data on factors that causes cost overrun, they include: contractor's inexperience, inadequate planning, inflation, incessant variation order, and change in project design. They are critical to causing cost overrun, while project complexity, shortening of project period and fraudulent practices are found to be responsible. The data fall within the percentages of possible consequences of cost overrun when compared with those available in scientific literature. The data can provide insights on how to mitigate the risks of project deviation from initial cost and as-built project.

Construction 4.0 (C4.0) has tremendously impacted construction activities worldwide in recent times. This effect was made possible on account of innovations brought about by Industry 4.0 (I4.0). Industry 4.0 has the potential to create Construction 4.0 through the integration of the design, construction and maintenance of infrastructure through useful component integration for industrial and technological development. Therefore, this study aimed to present a pathway for achieving sustainable innovations and inclusive technological and infrastructural developments. The following parameters were reviewed in this study as part of the goals and objectives set in the survey: identifying the adaptable areas of Construction 4.0 in design, planning, construction and maintenance as part of infrastructural innovation in order to study the industrial application drivers of I4.0 and C4.0 hindrances in achieving C4.0; achieving the automation dream through C4.0, benchmarking the social and economic implications of C4.0 and identifying the issues and challenges in achieving sustainable innovation through infrastructural development and documenting the disruptive tools of C4.0 in achieving a sustainable design through technological development and examining the critical factors influencing the effective adaptation of C4.0 in achieving growth. The authors utilised 200 construction firms for this study using the Cochran and Slovin’s formulas. In addition, the sample size of 150 respondents that constituted the study were construction professionals. The respondents used the simple percentage, relative index, Spearman’s rank, Mann–Whitney U test, Kendall’s Tau test, Student’s t-test, ANOVA and chi-square tools in the data processing. The study found out, among other things, the following as part of the parameters earlier proposed: the introduction of a circular economy by adopting intelligent innovation, engaging new tools, technological innovation diffusion and the vertical and horizontal integration of versatile tools like I4.0 and C4.0 for inclusive technological development. This study recommended the objective and effective adaptation of I4.0 tools to enhance C4.0 for technical development, circular economic integration and a framework for sustainable innovation and a system for the inclusive monitoring of innovations in the design and planning of construction maintenance.

Abstract:Client relationship management (CRM) has become a subject matter of interest to both academics and business practitioners. This is because it reflects the need to manage successful and profitable client relationships for organizations. Construction organizations, as well as the construction industry, are vital components of economic development in Nigeria, but many organizations struggle to perform the client relationships expected of them. The use of social media in the present era has given power to the relevant stakeholders to express their perceptions to a very large audience on the social media platforms of construction organizations. The application of social media to marketing is essential to managing client relationships. This research has been carried out to examine the level of awareness and use of social client relationship management (CRM 2.0) in Nigerian contracting and consulting construction organizations. In other words, the purpose of the study is to examine the level of adoption of social media platforms in client relationship management in the construction industry in Nigeria. The study also assessed the barriers to the adoption of the use of social media platforms in client relationship management. Using a questionnaire survey, a purposive quota sampling technique was utilized for the collection of data from contracting and consulting firms. The findings reveal that contracting and consulting firms have little to no awareness of CRM 2.0. This study suggests that Nigerian construction organizations are still hesitant to implement social media in a business environment and fully adopt CRM 2.0 in the construction industry.

This dataset conducted a comparative analysis of sustainable construction practices of foreign and indigenous construction firms in Lagos state, Nigeria using a structured questionnaire survey. The dataset contains the level of awareness and consistency of practice of sustainable development on construction projects between the foreign and indigenous construction firms and the impact of implementing sustainable development practices. Descriptive analysis such as frequencies, percentage and mean score were used to present the quantitative data in form of tables. Further analysis of the dataset highlight the practices of indigenous and foreign construction firms in sustainable development which can be beneficial to stakeholders in environmental protection and mitigating climate change issues.

Climate change is much discussed among professionals, academics, governments, local and international organisations. It is a phenomenon that is increasingly gaining attention because of its negative impacts on human, and natural environments and the economy. Human activities exacerbate climate change and this in turn impacts on livelihood and environment. Urban activities such as transportation and building (household) related activities increase atmospheric concentration of greenhouse gases. Other activities that contribute to greenhouse gas emission include change of land use, removal of land cover, use of fertilizer, pollution of water bodies, deforestation, industrialization, urbanization and poor municipal waste management. However, it is quite unclear whether urban residents have adequate awareness and understanding of what the phenomenon entails and how their daily activities impact atmospheric greenhouse gases' concentration. To this end, questionnaires were distributed to 600 households selected from three local government areas in Lagos State. Data gathered were analysed and presented using tables, percentages, pie and multiple bar charts. Result of analysis indicate that although most urban residents indicate various level of awareness of occurrence, they are least aware of the contribution of household activities to atmospheric greenhouse gas concentration and that professional property managers hardly sensitize occupants in this direction. The study concludes by suggesting ways to call the attention of urban residents to the impact of household activities on atmospheric greenhouse gases' concentration with a view to reducing emission from this sector in the future.
