Sustainable construction practices are strongly correlated with a profitable and competitive construction industry, improved client satisfaction and efficient use of resources. However, due consideration is not being given to sustainable construction practices in Nigeria. Therefore, this study aims to identify the unsustainable construction practices on construction sites, the barriers to sustainable construction and possible strategies to improve sustainable construction in Nigeria.

A questionnaire survey of 50 construction sites was conducted with construction professionals on the sites as the specific target, out of which only 43 construction sites have at least a construction professional present at the site. Forty-three filled questionnaires from the respondents were used for descriptive (mean score, standard deviation and charts) and inferential analysis (t-test and Kruskal–Wallis) in this study.

The study shows that a large percentage (75%) of construction professionals in Nigeria are aware of sustainable construction. The descriptive and inferential analysis showed a disparity in the ranking of the 12 unsustainable practices, 14 barriers and 11 strategies among the respondents. Five unsustainable practices (“negative externalities”, “excess energy”, “unsustainable technologies”, “non-management of health and safety of workers” and “material waste”), six barriers to sustainable construction (“absence of historical data and exemplary projects on which construction professionals can build and learn from”, “lack of professional to handle the task”, “poverty and low urban investment”, “lack of urban and construction policy”, “lack of awareness” and “lack of technical know-how”) and three strategies to improve sustainable construction practices in Nigeria (“cooperation, partnership and participation”, “protection of biodiversity and conservation of natural resources” and “sustainability assessment system”) were found to be significant.

The study offers significant insights into the construction industry unsustainable practices, barriers to sustainable construction, as well as strategies for improving sustainable construction practices. These insights can be applied to other developing countries with an emphasis on geographical differences.

To the best of the authors’ knowledge, this is one of the recent studies in Nigeria that explored the context of sustainable construction in the construction industry by providing insights into the unsustainable construction practices, barriers and strategies to improve sustainable construction in Nigeria.

The adoption of green building concepts and practices is rapidly gaining momentum globally due to their tendency to mitigate adverse effects of construction activities on the environment. The purpose of this study is to examine the challenges and benefits of implementing green building development in Nigeria.

Primary data were collected from questionnaires administered to 122 participants selected using stratified sampling techniques in North-East Nigeria. Semi-structured interviews complemented survey findings with proposed solutions. The quantitative data were analysed using descriptive statistics to identify the benefits and challenges, while thematic analysis was used to identify effective measures to the challenges of green building.

Results show that “conservation of natural resources”, “reducing maintenance” and “heightened aesthetic” were rated higher as environmental, economic and social benefits, and thus were significant to green building development. The study revealed “economic issues”, “government issues” and “absence of standard assessment system” were the key factors as internal, external and general challenges to green building. Most practical solutions were related broadly to policy, awareness and support as measures to challenges of green building development.

The study is imperative to bridge the knowledge gaps and provide empirical information for green building policy guidelines specific to North-East Nigeria’s built environment sector. The understanding of policy implications will assist in building regulatory and monitoring agencies in developing new internal management policies to inform the public and investors about the effects of green building development.

This paper aims to explore and review the critical perspectives of stakeholders in the facility management (FM) industry as regards the barriers to building information modelling (BIM) integration, with the view to providing significant insights to mitigate the barriers to BIM implementation.

An extensive literature review was conducted to identify critical barriers to BIM–FM integration. Ten categories of barriers were identified from the literature review and used to design a Likert scale-based questionnaire, which was administered to registered members of International Facility Management Association based in Lagos, Nigeria. The data collected were analysed using both descriptive (mean score, standard deviation, frequency tables and charts) and inferential statistics (Shapiro–Wilk and Kruskal–Wallis tests).

The descriptive and inferential analysis demonstrated a disparity in the ranking of the ten barriers among the groups. Six (out of ten) barriers to BIM implementation for FM practices are identified as critical (mean score greater than 4.0): insufficient awareness levels of BIM–FM integration benefits, non-existence of contractual and legal framework for BIM implementation, limited studies on BIM–FM inter-relationship, poor acceptance levels and resistance to change among stakeholders, perception of BIM and inadequacy of mode data. And the results of the one-sample t-tests show that there were statistically significant differences in the six.

This study offers significant insights to industry stakeholders in understanding BIM implementation barriers in FM, as well as the framework for mitigating them. These findings could also be applied to other developing countries, with special consideration given to locational differences.

The valuable information provided in this study could be used as a roadmap to improve BIM–FM practice implementation in Nigeria. It also measured differences in the opinions of professionals.

Despite the growing use of Fourth Industrial Revolution (4IR) technologies in construction, the reasons behind adopting social media in this context and its real benefits for sustainable construction and productivity remain unclear. This study aims to examine how construction professionals perceive the impact of social media on sustainable construction and productivity in the industry.

This research used a mixed-methods research approach (qualitative and quantitative), resulting in the formulation of a well-structured questionnaire which was distributed to construction professionals. Ordinal regression and multinomial logistic regression were carried out to assess the impact of social media use on sustainable construction and productivity enhancement, as well as the extent of social media utilization in construction projects.

Through exploratory factor analysis, five distinct clusters of social media consequences were identified, namely: information and knowledge sharing, community engagement and morale, environmental and resource management, disruptive and stressful effects and communication and collaboration. Furthermore, the extent of social media usage is closely related to three key factors: community engagement and morale, environmental and resource management and communication and collaboration.

This study represents one of the pioneering research efforts in Nigeria to investigate the implications of social media usage in the construction industry. Thus, future studies can build upon this research to further contribute to the multifaceted dimensions of social media’s impact on the construction industry.

The adoption of emerging technologies is critical to enhance construction industry performance. Previous studies have shown that the Nigerian construction industry (NCI) is slow to adopt digital technologies and faces performance issues. As a result, this study aims to investigate and model the barriers to adopting digital twin (DT) technology in the NCI with the view to provide stakeholders with adequate information on the multifaceted nature of DT barriers and provide strategies to improve DT adoption.

The study adopts a qualitative and quantitative approach to achieve the overall aim of the study. The qualitative approach included a scoping review used to identify barriers to DT adoption from the literature. A five-point Likert scale questionnaire was administered to 246 construction professionals in the NCI. This was followed by critical analysis using mean ranking and standard deviation, Kruskal–Wallis, factor analysis and partial least squares structural equation modelling (PLS-SEM).

The exploratory factor analysis revealed four categories of barriers to DT adoption in the NCI: “technological and investment”, “data management and government”, “project and human resources” and “digital transformation”. The PLS-SEM results revealed the causal relationships of four barriers categories and their concomitant effects on DT adoption in the NCI. The top three barrier categories that require critical attention in order of significance are: technological and investment (ß = 0.655), data management and government (ß = 0.313) and project and human resources (ß = 0.194). Digital transformation (ß = −0.046) has the least significance. Overall, all the barriers’ categories were accepted at a significance level of p < 0.05.

The practical implications include guiding policymakers and practitioners in making informed decisions to address the identified barriers to DT adoption in the NCI. The findings may also be applicable to other developing countries in Africa and beyond. By implementing effective policies and stakeholder guidelines, the NCI can advance technologically and enhance its competitiveness to execute advanced construction projects.

This research contributes to the construction industry by shedding light on the barriers to DT adoption and their intricate interconnections within the NCI context. It is also the first study in NCI context to present the level of DT awareness and explore the concomitant effects of the barriers.

Errors or negligence are inherent parts of professional services, thus necessitating the adoption of professional indemnity insurance (PII) as a risk management tool to protect professional interest. This paper sought to examine the adoption of PII among Estate Surveying and Valuation firms in Oyo State, Nigeria.

The quantitative research methodology was adopted, and primary data were collected via questionnaires distributed to 84 purposively selected Estate Surveyors and Valuers (ESVs) who are mostly principal partners or branch managers in the study area. Sixty-three questionnaires representing 75.0% were returned and found useable. Data collected were analysed with the aid of descriptive statistics of percentages and relative importance index (RII).

The study found that the influence of foreign investors as well as the requirements of PII by the professional body as a basis for annual license renewal were responsible for higher level of awareness among the practitioners. However, about average of the firms had adopted PII with few taking professional insurance policy of as low as ₦500,000 per annum. The study recommends that NIESV/ESVARBON should sensitize, monitor and enforce the adoption of PII by ESVs as a means to increase public confidence and credibility of valuers while rendering professional services to clients.

The current study was limited in coverage to Ibadan thus necessitating a study with wider area of coverage of national status.

The study has major implications on real estate education and practice in Nigeria. There is an urgent need for the professional body to devise means of enforcing compliance with the adoption of PII so as to be able to get the confidence of their teeming clients for subsequent patronage.

The paper is one among the scanty studies that provides a useful guide to real estate practitioners in developing countries towards adopting PII to shield the company from unnecessary negative exposure and financial loss.

Technological disruption has transformed the traditional ways of doing business in the real estate sectors. As a result of the new business realities, technology has become an integral part of the real estate business. However, due to the significant barrier to the incorporation of the technology among modern real estate start-ups, there is a need to assess the adoption and willingness to use property management software.

The study employed an exploratory research design. The study adopts a total enumeration of real estate start-up firms in Lagos, Nigeria, to ensure true representations among the respondents and reduce sampling errors. The data obtained were analyzed using descriptive and inferential statistics.

The study revealed that the majority of the respondents are aware of the identified property management software but tenant verification software recorded the highest level of awareness and usage. The finding also revealed that the association between the availability of staff competence, practicality of the software, ease of use, data ownership and copyright, financial resources, future-proof technology track, Internet connection, perceived benefits and productivity and branding are statistically significant in influencing the level of adoption among the respondents.

The researchers had initial challenges with the attitude of respondents to willingness and timely disbursement of information which was later resolved by explaining the significance for the study. The findings of the research will be useful and serve as an eye opener to practitioners, the conventional real estate surveying and valuation firms, to relevance of software technology in enhancing their operations and efficiency, while it can also boost the academic curriculum.

The knowledge about the adoption of property management software will equip real estate tech start-ups with the right information.

The paper is significant because the ultimate goal of this study is to document the empirical investigation on the level of adoption and application of emerging software among real estate tech start-ups in the Nigerian property market to facilitate the efficiency and delivery of property management services.

The study aims to develop a model that supports the application of data science techniques for real estate professionals in the fourth industrial revolution (4IR) era. The present 4IR era gave birth to big data sets and is beyond real estate professionals' analysis techniques. This has led to a situation where most real estate professionals rely on their intuition while neglecting a rigorous analysis for real estate investment appraisals. The heavy reliance on their intuition has been responsible for the under-performance of real estate investment, especially in Africa.

This study utilised a survey questionnaire to randomly source data from real estate professionals. The questionnaire was analysed using a combination of Statistical package for social science (SPSS) V24 and Analysis of a Moment Structures (AMOS) graphics V27 software. Exploratory factor analysis was employed to break down the variables (drivers) into meaningful dimensions helpful in developing the conceptual framework. The framework was validated using covariance-based structural equation modelling. The model was validated using fit indices like discriminant validity, standardised root mean square (SRMR), comparative fit index (CFI), Normed Fit Index (NFI), etc.

The model revealed that an inclusive educational system, decentralised real estate market and data management system are the major drivers for applying data science techniques to real estate professionals. Also, real estate professionals' application of the drivers will guarantee an effective data analysis of real estate investments.

Numerous studies have clamoured for adopting data science techniques for real estate professionals. There is a lack of studies on the drivers that will guarantee the successful adoption of data science techniques. A modern form of data analysis for real estate professionals was also proposed in the study.

The paper aims to examine the influence of urban violence on residential property rental value in Kaduna metropolis. This is motivated by the spate of insurgency and the attendant destructions of land and properties in the past few years in the study area.

This paper adopted a survey of key sites of urban violence and also a total enumeration of all the 67-estate surveying and valuation firms in the study area to elicit from them vital information on trends on rental from 2011 to 2019. The data obtained were analyzed using both descriptive and inferential methods of statistical analysis.

The result of this study revealed that among other sources of urban violence, violence fueled by ethnic affiliations/convictions is the only significant factor that influenced rental value of residential property in the study area. The regression analysis shows that ethnic violence accounted for 21.6% of the variability observed in residential property rental value over the period of study. Furthermore, the correlation result showed that ethnic violence is negatively correlated (−0.458) and significantly related to residential property rental value.

This study concluded that the emergence of urban violence in Kaduna metropolis contributed to a fall in the rental value of residential property in the study area. This study thus suggested policy directions that could engender harmonious coexistence among different ethnic groups in the study area.

This study is expected to enhance improvement in residential property rental value in Kaduna metropolis through increase assurance to security of lives and property.

Challenges of property data in developing markets have been reported by several authors. However, a deep understanding of the actual nature of this phenomenon in developing markets is largely lacking as in-depth studies into the actual nature of data challenge in such markets are scarce in literature. Specifically, the available literature lacks clarity about the actual nature of data challenges that developing markets pose to valuers and how this affects valuation practice. This study provides this understanding with focus on the Lagos property market.

This study utilises a qualitative research approach. A total of 24 valuers were selected using snowballing sampling technique, and in-depth semi-structured interviews were conducted. Data collected were analysed using thematic analysis with the aid of NVivo 12 software.

The study finds that the main data-related challenge in the Lagos property market is the lack of database of market property transactions and not the lack or absence of transaction data as it has been emphasised in previous studies. Other data-related challenges identified include weak property rights institution with attendant transaction costs, underhand dealings among professionals, undocumented charges, undisclosed information, scarcity of data relating to specialised assets and limited access to the subject property and required documents during valuation. Also, the study unbundles the factors responsible for these challenges and how they affect valuation practice.

The study has implication for practice in the sense that the deeper knowledge of data challenges could provide insight into strategy to tackle the challenges.

This study contributes to the body of knowledge by offering a fresh and in-depth perspective to the issue of data challenges in developing markets and how the peculiar nature of the real estate market affects the nature of data challenges. The qualitative approach adopted in this study allowed for a deep enquiry into the phenomenon and resulted into an extended insight into the peculiar nature of data challenges in a typical developing property market.
