Green building is a relatively new concept with limited applications in property development in South Africa. The objectives of this study are therefore threefold: identify key green building principles considered by property developers, establish the benefits of implementing the principles and determine the barriers to its applications.

The study adopted a case study of two Green Star South Africa (SA)-certified buildings in Sandton, Johannesburg. These are Alexander Forbes building, and Ernst & Young Eris Towers. The two certified buildings were purposefully selected because of the insightful information they provide regarding application of green building principles. The main themes investigated in the cases are environmental awareness, green building principles applications, as well as benefits and barriers of green building. A total of six interviewees from the contractors', property developers', environmental/green building consultants' and sustainability consultants' organizations who were involved in the implementation of green building principles in the two cases provided the qualitative data for the study. The qualitative data were supplemented with data relating to the two case studies obtained from the ‘Earth Works for a Sustainable Built Environment’. The interviews were arranged over a period of two months, and each interview took between 20 and 30 minutes. Analysis of the data was done through a phenomenological interpretation of the qualitative opinions expressed by the interviewees.

Key green building principles comprising energy efficiency, water efficiency, resource efficiency, occupants' health and well-being and sustainable site development were implemented in the two cases. The fact that the buildings were rated 4-star enabled inference to be drawn that the implementation of the principles was less than 60 per cent. Energy efficiency of 35 per cent indicated in Case I suggests that the level is consistent with the South African green building standard of 25 per cent to 50 per cent. However, the energy and water efficiency assessment of the building were based on projections rather than on ongoing monitoring and evaluation of the buildings' performance. Moreover, perceived saving in operational cost was identified as dominant driver to green building principles implementation. Conversely, lack of government incentives and absence of reliable benchmarking data regarding performance of green buildings were major barriers to its full implementation.

The findings of this study provide important implications to the developers and government on the application of green building principles. In the first place, the evidence that initial high cost premium could be off settled by long- term saving on operational costs as a result of use of local materials, energy and water savings as well as use of recycled material, as implemented in the two case projects, would improve investment decision in green building by developers. The understanding of the drivers and barriers to implementation of green building principles also has implications for guiding government policies and programmes towards green building.

The significance of this study stems from the fact that limited studies, especially in the South African context, have indicated the drivers and barriers to the implementation of green building principles. The case study approach adopted gave a novelty to the study by providing hands-on information from the stakeholders who were known to have played specific roles in the application of green building. The findings indicated that initial high cost premium was not a consideration in developers' choice of green building which justifies the possibility of a costlier product when factors such as environmental sustainability benefit is considered to be ultimate. The study thus suggests further research involving larger cases on energy efficiency, water efficiency and costs of green buildings compared to the conventional type to bring the findings to a broader perspective and assist to benchmark data for green building assessment.

The purpose of this paper is to examine the challenges to data sharing among construction stakeholders in the South African construction industry and also assess stakeholders’ perceptions of the benefits of data sharing.

This study is a cross-sectional survey administered via a Web-based online survey on construction professionals registered with the South African Council for the Project and Construction Management Professions (SACPCMP). The respondents rated on a five-point Likert scale the level of influence of the challenges of, and the benefits derivable from data sharing. These were analysed using descriptive and inferential statistical techniques.

The results of the principal component analysis (PCA) presented a five-factor structure of the challenges to data sharing, including reporting context/framework/lack of expertise, cost considerations/clients’ influences, data interoperability, stakeholders conservative attitude and personal interest/data confidentiality. These have percentage variances 17.124%, 16.929%, 13.786%, 13.353% and 12.961%, respectively. For the benefits of data sharing, the constructs were categorized into four themes, namely, optimal project decisions/stakeholders’ confidence, benchmarking/ collaboration among firms, time and cost benefits and enhanced market intelligence. These have respective variances of 24.598%, 18.393%, 16.160% and 14.685%.

It is expected that this study will provide information to stakeholders towards implementation policies and practices that could eliminate the challenges to data sharing and assemblage, thereby enhancing the level of data sharing in the construction industry.

Given the increasing global and technological changes, it might be expected that there will be an increased appeal by construction stakeholders towards embracing data sharing and assemblage owing to the inherent benefits and value.

Sustainability transformation in the construction industry is vital for the attainment of sustainable development goals. While conventional construction has been at the expense of social and economic sustainability, sustainable construction can enhance environmental, social and economic outcomes for the construction industry and society at large. However, the industry struggles with new initiates because its stakeholders are products of unique institutions which shape their decisions and intentions to adopt new practices. This study assessed the institutional pressures that influence the adoption of sustainable construction to enhance our understanding of other factors that can promote and accelerate the adoption of sustainable construction.

The study adopted a quantitative research design with the use of online questionnaires to elicit information from construction professionals in South Africa. Descriptive statistics of frequencies, mean and standard deviation were used to analyse the data obtained from the survey. Linear regression was also used to assess the influence of institutional pressures on the adoption of sustainable construction.

Mimetic pressures were found to have a significant influence on the adoption of sustainable construction. The decision to adopt sustainable construction was based on the sustainability actions of industry leaders (mimetic pressure). Normative and coercive pressures had no significant influence on the adoption of sustainable construction.

Mimetic pressure from competitors and normative pressures is already exerting some pressure on stakeholders to adopt sustainable construction. However, there cannot be a long-term commitment that will yield the needed sustainability transformations without additional normative pressure from learned societies and coercive pressure from the government. As one of the pioneering works from the global south, this study provides empirical validations of the influence of institutional pressures on the adoption of sustainable construction. It also enhances understanding of how institutional pressures from the social context can promote and accelerate the adoption of sustainable construction.

The findings present one of the pioneering efforts to empirically validate the influence of institutional pressures on the adoption of sustainable construction.

The aim of this paper is to assess the behavioural factors that influence professionals' intention to adopt green construction based on the theory of planned behaviour (TPB).

The study adopted a quantitative research design with the use of online questionnaires to elicit information from construction professionals in South Africa. Descriptive statistics of frequencies, mean and standard deviation were used to analyse the data obtained from the survey. Linear regression was also used to assess the effect of behavioural factors on professionals' intention to adopt green construction.

The results showed that attitude and perceived behavioural control (PBC) have a significant effect on the intention to adopt green construction. These were significant at p < 0.05, having p-values of 0.000 and 0.015 respectively. The study also found that there was a positive disposition towards green construction, particularly with regards to insisting on green construction. This had a mean value of 3.99. There was also a high perception of succeeding in the execution of green projects with mean score of 3.76.

The practical implication of the findings is that adoption of green construction in South Africa is majorly based on the positive attitude of stakeholders towards green construction and also the PBC or the perceived ease of executing green construction. However, these factors are not sufficient to generate long term commitment for green transformation among a critical mass of stakeholders in the South African construction industry. Hence, there is a need for focus on subjective norms (pressure) particularly from the government, to encourage the widespread adoption of green construction in South Africa.

Findings present one of the pioneering efforts to empirically validate the influence of behavioural factors on the intention to adopt green construction in South Africa and the outcomes can provide policy directions and baseline data for further research.

The global shift in the traditional skills required of real estate graduates has led to an increased demand for employees who have the required skills and competencies. The purpose of this study is to evaluate employment considerations of real estate firms and analyse employers’ skill expectations and the observed skills possessed by the graduate employees. This study also analysed the self-assessed soft skill levels of the graduate employees, thereby establishing the skill gap.

Data were sought from real estate employers in the two dominant real estate markets of Nigeria: Lagos and Abuja, and real estate graduate employees who have had a minimum of six months working experience in real estate firms. Data collected were analysed using statistical techniques such as frequency, percentages, mean, correlation, multivariate analysis of variance, paired-samples t-test and independent samples t-test.

The findings of this study revealed that employers’ soft skills expectations were high with skills such as responsibility, administrative, listening, communication, business negotiation and work ethics. Based on employers' observed skills, there were significant skill gaps with respect to soft skills such as responsibility, business negotiation, logical thinking, marketing and dispute resolution. An analysis of the core skills reveals employers' preference for technical competencies in valuation, agency, property management, marketing, report writing and landlord and tenant laws. However, graduate employees possessed significant skill gaps with regards to technical skills such as valuation, property investment analysis, feasibility and viability appraisal, market research methods and facility management.

An understanding of the skill gaps will provide useful feedback to professional bodies, regulatory boards, institutions of higher learning, faculty members and other stakeholders regarding deficient skill areas, especially for curriculum review, development and training in the real estate sector.

There is a paucity of information about employers' skill preferences and the skill gaps in the real estate sector.

Coworking space had been a trajectory in the commercial space operation and management globally. Commercial coworking/tenancy space is confronted with an unexpected shift. This paper aims to examine the peculiarity and investment characteristics of flexible office space and the post-COVID implications on coworking office space practice and investment. This is with a view toward providing investors with an understanding of the dynamics underpinning flexible office space investment in the Nigerian emerging property market.

This study adopted a qualitative research approach. Open-ended interview questions were used to solicit information from nine coworking space operators in the urban property market of Ibadan, Nigeria. The structured interview data were analyzed using Atlas.ti – a computer-aided qualitative data analysis software.

The findings show that the factors influencing demand for flexible office space in the study area include flexibility, affordability, cost-effectiveness, entrepreneurship motivations and opportunity for risk sharing. The results also revealed that coworkers are predominantly mobile individuals who require a workstation away from their homes or a traditional office setup. Management challenges include deficient infrastructure, low level of awareness, stealing and high cost of operations. The impact of COVID-19 includes a drop in patronage, rent refunds, changes in working pattern and job loss, restriction to online and remote operation, the extra cost of putting prevention measures in place, changes in tenancy contract and drops in return on investment.

This study has implications for investors in commercial space occupation and leases in comparable developing economies.

The novelty of this paper lies in its relevance with the emergent behavioral changes, orchestrated from the novel COVID-19, which compels reevaluation of workplace practices and investment for economic improvement, especially as it relates to commercial real estate investment.

The South African construction industry appears to be lagging behind other industries in the country in terms of implementation and adoption of innovative technologies. Moreover, sufficient empirical data on the adoption of innovative technologies, especially, in developing countries are not readily available. The aim of this study is therefore to assess the adoption and implementation of innovative technologies in the South African construction industry with a view to improving the industry's performance.

A survey was undertaken using a questionnaire, administered to construction professionals primarily in project management, quantity surveying and architectural firms.

The key findings show that there are some innovative technologies such as building information modelling, 3-dimensional mapping, drones, 3-dimensional printing and virtual reality that have been deployed. However, limited adoption of innovative technologies within the industry and low levels of knowledge of its benefits among the respondents were reported. This low implementation of innovative technologies was due to critical barriers such as high cost, limited knowledge, time requirement, fear of change, lack of interest, nature of construction processes and lack of team dynamics. Key drivers of innovation were found to include globalization and competition.

The current level of implementation of innovative technologies indicated that they are not yet optimized in the South African construction industry and suggests implications for change, adaptation and growth. The study recommends that firms should consider investing in research and development in order to exploit the potential of innovation for organizations and the industry at large.

The drivers and barriers indicated will help to prioritize the direction of adoption and growth which could help to improve the industry.

Life cycle costing (LCC) has become increasingly important in construction projects over the last decades. However, limited empirical studies have been carried out on the factors influencing its application in building projects, particularly in developing countries. The purpose of this study is to address this gap in knowledge within the Nigerian context.

Primary data were used through the administration of questionnaires to practising quantity surveying firms in Lagos State, Nigeria. The data obtained were analysed using both descriptive and inferential statistical tools including percentages, mean item score and factor analysis.

The study identified 47 barriers to the application of LCC, and the analysis of the ranking revealed that 35 (of 47) identified barriers were considered important. Factor analysis grouped the identified barriers into four key factors namely, professional incompetence; cost implications; administrative factor and procurement options.

This research is important by providing the empirical evidence on the barriers to the application of LCC in developing countries, particularly in Nigeria. For instance, the identification of important barriers to LCC use will enlighten the construction professionals to be trained in the practicalities of LCC. Moreover, the study provides implications for construction stakeholders (including governments) to draw policy recommendations that will positively improve the use of LCC in the construction industry, especially in developing countries.

The study will be beneficial to all the construction stakeholders by broadening their awareness about the barriers to LCC use in Nigeria and developing countries at large.

This study investigates the impact of mentoring on real estate students' entrepreneurial intentions with a focus on Nigeria, an emerging African economy. Specifically, the study assessed the influence of mentoring on the entrepreneurial intentions and career preferences of real estate students and analysed the influence of having a real estate mentor on the respondents' perception of the motivators and inhibitors to their entrepreneurial intentions.

The study adopted a descriptive research approach using closed-ended questionnaires. The study population comprise final year real estate students selected from three federal universities offering Real Estate in southwest Nigeria. Total enumeration was adopted for the study. From a total population of 231 students, a response rate of 69.26%, representing 160 questionnaire were retrieved and found suitable for the analysis. Descriptive and inferential statistical techniques were employed for data analysis.

The result shows that the factor structure of the motivators for students who have real estate mentors clustered into four constructs; in order of influence are personal fulfilment/satisfaction, flexibility/financial motives, mentoring/economic influences and personal preferences/prestige and status. Meanwhile, economic/independence, personal preference/fulfilment, financial motives/self-perception and mentoring were the factor clusters influencing intention for real estate enterprise by students who have no real estate mentor. Predominant debacles across both categories of respondents relate to the lack of support and market uncertainty.

There is a growing body of knowledge exploring the linkages between mentoring and the development of entrepreneurial intentions. However, scant empirical investigations have examined the impact of mentoring on real estate students, especially from the perspectives of emerging markets which are usually characterised by low economic opportunities and where issues of graduate unemployment appear endemic and yet to be appropriately resolved.

This study explores the implications of mentoring on the entrepreneurial intentions of real estate students' from the perspective of an emerging market.

The purpose of this paper is to evaluate critical factors that impact public sector organizations’ (PSOs) performance in PPP contracts with a view to improving their capabilities toward efficient project delivery and attracting more private sector investments.

The research methodology is a quantitative approach which commenced with an in-depth literature review that provided the basis for identification of the variables that were evaluated through a structured questionnaire. Respondents were professionals from stakeholders’ organizations that had been involved in PPP contracts in the Southwestern region of Nigeria selected using respondent driven sampling technique. These include industrial practitioners from governmental-based organizations (ministries, agencies, corporations/parastatals, etc.), private developers/concessionaires, law firms, and banks, among others. Data collected were analyzed using mean, relative significance index) and factor analysis.

The critical performance factors of PSOs in concession contracts clustered under nine components. These were technical, legal, political, finance, market maturity, economic, procurement process, performance guarantee and degree of regulation. PSOs’ capability development measure in countries newly experimenting with concession model is expected to focus on these factors for improved project delivery.

The study provided implications for capabilities improvement, legislation and policy making with respect to PPP transactions in countries newly experimenting with PPP contracts. This is highly significant to improving the capabilities of PSOs and attraction of more private sector partnership in infrastructure delivery through the concession model.

The study provided implication for capabilities improvement, legislation and policing with respect to PPP transactions in countries newly experimenting with PPP contracts. This is highly significant to improving the capabilities of PSOs and attraction of more private sector partnership in infrastructure delivery through concession model.

Previous studies on PPP performance had either focused on the projects or generalized the performance assessment to PSOs and private investors. This study extended the researches on PPP performance by revealing factors specific to the public sector stakeholders.
