Studies show that the fourth industrial revolution (4IR) technologies can be used to transform the built environment sector in the 21st century. Blockchain technology has been identified as one of the drivers of 4IR that could be a channel of innovation in the built environment. Studies concerning the application of blockchain technology in Nigeria’s built environment are scarce. Thus, this study aims to investigate the relevance of blockchain technology to the Nigerian built environment professionals (BEP) in the 21st century and proffer ways to promote the applications in the sector.

Given the unexplored nature of the issue in Nigeria’s context, 20 semi-structured virtual interviews were conducted across Lagos and Abuja cities. The participants were knowledgeable in construction-related information technology, from construction contracting firms and construction consulting firms, academicians in construction consultancy and internet and communication technology experts. The collated data were coded, analysed and presented in themes via a thematic approach.

Automating construction progress payments in smart contracts, financial management and supply chain management reduces transaction costs emerged as the key areas where blockchain technology can benefit the Nigerian BEP if well implemented. Others are blockchain-based BIM and prevents forgery and alteration of data, contract management and blockchain-based building information modelling (BIM). Blockchain technology applications are not without some hindrances. The 22 perceived hindrances were government, employer and employee related in Nigeria’s built environment.

This research is restricted to the relevance and encumbrances facing the applications of blockchain technology in Nigeria’s built environment. Also, this study proffers policy solutions to promote the application of blockchain technology in the built environment via a qualitative method. Future study becomes pertinent to explore other components of the 4IR and their relevance within Nigeria’s built environment.

Results from this paper will strengthen and offer a rich insight into the relevance of blockchain technology in the Nigerian built environment. Other developing nations with similar challenges may consider the recommendations from this study. This study will contribute towards stirring the parties to create a good platform and supporting policies to promote the applications and implementation of blockchain technology across the industry.

This paper is one of the few papers that attempted to uncover issues that hinder blockchain technology applications in the Nigerian built environment via a qualitative approach and proffer feasible solutions from the practitioners’ perspective.

The purpose of this paper is to examine the extent to which a systematic review approach is transferable from medicine to multi-disciplinary studies in the built environment research.

Primarily a review paper, it focuses on specific steps in the systematic review to clarify and elaborate the elements for adapting an evidence base in the built environment studies particular to the impact of green building on employees’ health, well-being and productivity.

While research represents a potentially powerful means of reducing the gap between research and practice by applying tried and tested methods, the methodological rigour is debatable when a traditional systematic review approach is applied in the built environment studies involving multi-disciplinary research.

The foundational contribution of this paper lies in providing methodological guidance and an alternative framework to advance the longstanding efforts in the built environment to bridge the practitioner and academic divide.

A systematic review approach in the built environment is rare. The method is unique in multi-disciplinary studies especially in green building studies. This paper adopts the systematic review protocols in this cross-disciplinary study involving health, management and built environment expertise.

The purpose of this paper is to develop a comprehensive picture of characteristics affecting the employment outcomes and patterns for real estate graduates in Australia. Furthermore, this paper benchmarks the characteristics affecting employment prospects of real estate graduates against those of built environment graduates.

The data used in this paper were collected by the Australian Graduate Survey (AGS). Dimensionality reduction was used to prepare the dataset for the courses listed in the AGS data, in order to develop the simplified classifications of courses used to conduct the analysis in this paper. Dimensionality reduction was also used to prepare the dataset for the analysis of the employment outcomes and patterns for real estate and built environment graduates. Descriptive and statistical analysis methods were used to identify the difference in characteristics, such as gender, age, attendance type, mode of study, degree levels and English proficiency, for real estate and built environment graduates, the level of the influence of these characteristics on their employment outcomes and patterns and the statistical relationship between individual characteristics and employment outcomes as well as employment patterns of the graduates.

English proficiency was found to be an important factor for real estate and built environment graduates for securing employment and it has a statistically significant impact on the employment outcomes and patterns for the graduates. Despite the fact that age and attendance type have no statistical impact on employment outcomes for real estate and built environment graduates, they were found to have statistical significant impact on their employment patterns.

This is pioneering research which used official government data, such as AGS data, to provide a reliable and thorough picture of the employment outcomes and patterns for real estate and built environment graduates.

Studies show that building information modelling (BIM) technology can improve construction productivity regarding the design, construction and maintenance of a project life cycle in the 21st century. Revit has been identified as a frequently used tool for delivering BIM in the built environment. Studies about BIM technology via Revit are scarce in training middle-level workforce higher education institutions. Thus, this study aims to investigate the relevance of BIM technology and offer measures to promote digitalisation in Nigeria’s built environment polytechnic undergraduates via Revit.

Given the unexplored nature of training the middle-level workforce in Nigeria, 37 semi-structured virtual interviews were conducted across Nigeria, and saturation was achieved. The participants were knowledgeable about construction-related BIM. The researchers used a thematic analysis for the collected data and honed them with secondary sources.

Improved visualisation of design, effective and efficient work productivity, automatic design and quantification, improved database management and collaboration and data storage in the centrally coordinated model, among others, emerged as BIM’s benefits. BIM technology via Revit is challenging, especially in Nigeria’s polytechnic education curriculum. The 24 perceived issues were grouped into government/regulatory agencies-related, polytechnic management-related and polytechnic undergraduate students-related hindrances in Nigeria’s built environment.

This study is limited to BIM implications for Nigeria’s built environment polytechnic undergraduates.

This study contributes to the literature paucity in attempting to uncover perceived issues hindering the implementation of BIM technology via Revit in training Nigeria’s built environment polytechnic undergraduates via a qualitative approach.

Nigeria has one of the highest graduate unemployment rates in Africa, and there is no comprehensive policy framework to address it. Evidence shows that integrating craftsmanship into higher education academic programmes can enhance graduate employability. Therefore, there is a need to integrate it into the built environment programmes at institutions in Nigeria. The built environment craftmanship (BEC) in Nigeria's HEIs may have had some challenges, although studies about these challenges are scarce. In this regard, the study investigated BEC's perceived encumbrances and proffered measures to integrate craftsmanship skills in Nigerian HEIs built environment programmes.

The research adopted a qualitative research design using a virtual interview approach to solicit data from 34 experts across Nigeria. An exploratory approach was used to engage selected HEIs in Nigeria and thematic analysis was adopted to analyse the collected data, and saturation was achieved.

The study findings indicate that integrating BEC in built environment programmes will enhance graduate employment. However, possible encumbrances like institutional frameworks, funding, infrastructural development and pedagogical and social-cultural issues were found to be affecting BEC's integration into built environment programmes at higher education in Nigeria.

Future studies should explore more detailed large-scale investigations about integrating craftsmanship into higher education institution (HEI) programmes.

Given the dearth of pragmatic studies on the built environment graduates' unemployment in Nigeria, this research contributes to the academic community debates on reducing graduates' unemployment via BEC in HEIs.

Neuroarchitecture is a new interdisciplinary research field combining neuroscience and architecture that has developed and expanded since 2000. Neuroarchitecture originated from the divergence of previous multidisciplinary studies on the relationship between humans and the environment. However, scoping reviews of neuroarchitecture in relation to the experience of the built environment are lacking. Thus, this study aimed to provide the background and research trends of neuroarchitecture to contribute to discussions on the built environment.

A general form of scoping review was adopted, following the PRISMA-ScR checklist. For this scoping review emphasizing the embodied implication of neuroarchitecture for the built environment, an evaluation framework was developed consisting of four categories: health, performance, aesthetics and emotion.

This study explores objective techniques, including electroencephalography and functional magnetic resonance imaging, electrocardiogram, electrodermal activity and saliva cortisol, to measure neurophysiological impacts, adopting real, virtual and images of environmental settings. An in-depth review of 25 selected papers revealed the existing empirical research on neuroarchitecture using human physiological measurement tools and representational environment settings to examine the impact of human–environment relationships.

A meta-analysis of theoretical and intervention studies on neuroarchitecture that investigates the multisensory characteristics of the environment is lacking. In addition, the development and application of wearable tools to meet the needs of real environment settings can improve the effectiveness of neurophysiological measurement tools.

This study aims to determine the design factors that may affect the design of disabled students. Additionally, this study assesses and compares the reality between the public Jordanian universities’ built environment and international universities based on the Americans with Disabilities Act checklist – version 2.1 – to provide an accessible built environment for physically disabled people. Furthermore, this study examines the satisfaction degree of physically disabled people with the built environment in selected universities. Besides, this study examines the relationships/interrelationships between the students’ demographic factors, design factors and the degree of the disabled students’ satisfaction.

This research used different data collection methods to answer the research questions: literature review, observation and questionnaire. Additionally, this study used different analytical and statistical methods, such as comparative analysis between the local cases and the selected international case study based on the Americans with Disabilities Act checklist, version 2.1, descriptive analysis and Pearson r correlational statistics.

This research found that the Jordanian public universities did not apply all required design factors to achieve a high degree of the built environment of accessibility and provide all the requirements and needs of physically disabled students like international universities. Additionally, half of the physically disabled students respondents were satisfied with the availability and quality of pathways, ramps, doors and corridors, non-slippery materials, elevators, accessible entrances, entrances doors, methods of openings, adequate spaces for wheelchair students at the configuration of the entrance and the availability of railing. In contrast, they were unsatisfied with the availability of parking and bathrooms for each gender and signage systems. Moreover, this research found no significant differences between gender and educational level and all factors that may impact the students’ satisfaction with campus environmental design. Furthermore, this research found that there was a strong to very strong positive linear association and a significant correlation/intercorrelation between the availability and the design quality of parking, entrances, doors, lobbies and corridors, bathrooms, signage systems and information, ramps, elevators and stairs and the disabled students’ satisfaction degree.

This research tends to help disabled students participate entirely and independently in the built environment and all aspects of society, involve them within the community and facilitate their access to universities’ urban space. This research considers guidelines and checklists for architects and policymakers to apply through all design and retrofitting processes to meet disabled students’ requirements. This research provides a vital understanding of the needs of disabled students in educational spaces to create a barrier-free campus environment.

Inclusive design is a relatively new architectural concept. It provides means to ensure access and equal participation in the built environment, offers the opportunity to improve and design new equivalent solutions in architecture simultaneously and covers the way for a broad clarification of equality. Applying the concepts of inclusive design is a step toward eliminating the barriers imposed on the built environment in public universities and creating an accessible built environment. In addition, this research can guide future research in other institutions.

The purpose of this paper is to investigate whether gender has an impact on real estate and built environment graduates’ employment outcomes, employment patterns and other important employment related issues, such as pay, role, contract type and employment opportunity in different states of a country.

The data used in this paper has been collected from the Australian Graduate Survey (AGS). Data from the years 2010-2012 was combined into a single data set. Dimensionality reduction was used to prepare the data set for the courses listed in AGS data, in order to develop the simplified classifications for real estate and built environment courses which are used to conduct further analysis in this paper. Dimensionality reduction was also used to prepare data set for the further analysis of the employment outcomes and patterns for real estate graduates. Descriptive and statistical analysis methods were used to identify the impact of gender on the employment outcomes, employment patterns and other important employment related issues, such as pay, role, contract type and location of job, for real estate graduates in Australia. This paper also benchmarks the employment result of real estate graduates to built environment graduates.

Recent male built environment graduates in Australia are more likely to gain full-time employment than females. The dominant role for recent female built environment graduates in Australia is a secretarial or administrative role while for the male it is a professional or technical role. Male real estate and built environment graduates are more likely to have a higher level of salary. Gender also has an impact on the contract type. Male built environment graduates are more likely to be employed on a permanent contract. On the other hand, gender has no impact on gaining employment in different states, such as New South Wales and Queensland, in Australia. The finding of this paper reinforces the view of previous literature, which is that male graduates have a more favourable employment outcomes and on better employment terms. The finding also shows that graduate employment outcomes for real estate and built environment graduates in Australia are similar to that in other countries, such as the UK, where equivalent studies have been published.

This is pioneering research that investigates the impact of gender on employment outcomes, employment patterns and other employment related issues for real estate graduates and built environment graduates in Australia.

Professionalism indicates a devotion to and demonstration of exceptional performance and achievement in any activity. The built environment comprises the physical items required for economic activity, long-term national development and social well-being. Studies show a need to improve many aspects of the built environment and the sector which creates it. Researchers should contribute to this improvement effort. It is suggested that researchers should demonstrate professionalism, but there is no agreement on how professionalism in research is determined. It is necessary to consider what constitutes professionalism in built environment research and how it can be developed.

An exploratory study is presented. It considers major works on the nature of the built environment and its sector, and factors influencing research on them; and draws on works on research ethics, integrity and good practice to propose a framework for professionalism in built environment research.

More work is needed to improve the built environment and its sector. Professionalism in built environment research will make the contribution of such research to this effort effective. This professionalism should be conceptualised, developed and continuously enhanced.

This first attempt to formulate a framework for professionalism in built environment research is based on a review of the major relevant literature. Subsequent works can test this framework empirically.

The professional built environment researcher will be committed to contributing to society.

This is the first work on professionalism in research on the built environment. The framework provides the basis for further studies on the subject.

Research reveals that the built environment graduates are not matching the needs of the 21st century construction industry. Evidence shows that the built environment academics (BEA) struggle to reskill and upskill to meet the industry's demand. Studies about Nigeria's BEA's perceived barriers in meeting the 21st-century industry demands are scarce. Thus, the paper investigated the perceived barriers and measures to improve BEA in Nigeria's 21st-century world of teaching. The outcome intends to enhance teaching practices and increase employability in the built environment disciplines.

Data were sourced from elite virtual interviews across Nigeria. The participants were well informed about Nigeria's built environment education and the possible barriers hindering 21st-century teaching from improving employable graduates in the built environment professionals (BEP). The researchers adopted a thematic analysis for the collected data and supplemented the data with secondary sources.

The study shows that BEA needs to improve BEA's teaching mechanism. Improving BEA will enable the built environment graduates to meet the minimum standards expected by the 21st-century industry. Findings categorised the perceived 22 barriers facing BEA into internal stakeholders-related barriers, external stakeholders-related barriers, and common barriers. Also, findings proffered practicable measures to improve BEA in the workplace via improved industry collaboration and technological advancement.

The research is restricted to the perceived barriers and measures to improve BEA in 21st-century teaching in Nigeria via a qualitative research design. Future research should validate the results and test the paper's proposed framework.

The paper confirms that the BEA requires stakeholder collaboration and technological advancement measures to improve teaching in the 21st century, leading to enhanced employability graduates. The paper would stir major stakeholders, especially BEA, and advance the quality of employable graduates in the Nigerian built environment professions.

The thematic network and proposed framework could be employed to stimulate Nigeria's BEA for better service delivery. This intends to create an enabling environment that will enhance stakeholders' collaboration and technological advancement for the BEA to produce better employable graduates in the 21st century.
