Abstract

Electric utilities traditionally operate as government monopoly institutions in vertically integrated structures. As monopolies, secondary costs incurred as a result of inefficient operations are passed down to consumers, even when such did not constitute major operational or quality of supply problems. In the 1990s, environmental issues, regulatory and economic challenges, and changing public perception created a radically different world for electric utilities. Consumers demand price transparency and reduction of cross‐subsidies among different users. The need for higher energy efficiency in technical systems of utilities and significant growth in energy demand were recognised. Most governments were under pressure to raise funds for social services, balance budgets and to carry out economic reform. This paper presents a review and analysis of the successful deregulation of the electricity supply industry in England and Wales as a pointer to other countries (e.g. developing countries) contemplating such programme.

Abstract

Sustainable building development involves several stakeholders, team participants and their fulfilment can affect the performance and outcome of succeeding construction development. The effect of the individual or human component is one of the most desperate reasons for the realisation of any progress in the building sector. Organisations are developing an increasing number of project teams to meet diverse organisational goals as they acknowledge the value and importance of project teams. However, in order to ensure that the project team achieves positive results, management, particularly the project manager, must focus on crucial elements such as team satisfaction. Project success can be influenced by team satisfaction. The project leader usually oversees and manages the team, organising and managing project activities between stakeholders and other team members. The study found that gratitude, enhanced morale, increased responsibility, putting in extra effort and job quality are all reasons why team satisfaction might affect a construction project's success.

Abstract

Purpose

Estimation of the rental price of a residential property is important to real estate investors, financial institutions, buyers and the government. These estimates provide information for assessing the economic viability and the tax accruable, respectively. The purpose of this study is to develop a neural network model for estimating the rental prices of residential properties in Cape Town, South Africa.

Design/methodology/approach

Data were collected on 14 property attributes and the rental prices were collected from relevant sources. The neural network algorithm was used for model estimation and validation. The data relating to 286 residential properties were collected in 2018.

Findings

The results show that the predictive accuracy of the developed neural network model is 78.95 per cent. Based on the sensitivity analysis of the model, it was revealed that balcony and floor area have the most significant impact on the rental price of residential properties. However, parking type and swimming pool had the least impact on rental price. Also, the availability of garden and proximity of police station had a low impact on rental price when compared to balcony.

Practical implications

In the light of these results, the developed neural network model could be used to estimate rental price for taxation. Also, the significant variables identified need to be included in the designs of new residential homes and this would ensure optimal returns to the investors.

Originality/value

A number of studies have shown that crime influences the value of residential properties. However, to the best of the authors’ knowledge, there is limited research investigating this relationship within the South African context.

Abstract

Purpose

While the declining rate of urban security and its potential effects have been globally acknowledged, the ways urban neighborhood security shapes real estate markets in African cities remain largely unexplained. The purpose of this paper therefore is to present the findings from a study of the nexus between urban neighborhood security and home rental prices in Lagos, Nigeria.

Design/methodology/approach

This paper is based on the hedonic price theory, an objectively derived urban neighborhood security index (UNSI) and property rental price data in Ojo, Lagos, Nigeria. This is a quantitative cross-sectional study that employs multistage sampling survey procedure. Data are analyzed using descriptive statistics, nonparametric correlation and hedonic price function with ordinary least squares (OLS).

Findings

Results show that nearly 50% of the study area is prone to insecurity and average rental values in Ojo, Lagos range from N151329.41 ($302.66) to N167333.33 ($334.67) per annum. Correlation analysis shows that home rental prices have high, positive and significant correlations (rs = 0.725 and p < 0) with UNSI. After controlling for neighborhood and structural factors, it is found that urban neighborhood security positively influences home rental values as a unit improvement in security leads to N81000.00 ($162.00) increase in rental value per annum.

Practical implications

Urban neighborhood security risk threatens residential property values, creates unintended residential mobility and destabilizes families. Findings from this study point to the facts that security is a key component of urban housing values and developers, and real estate investors must ensure that this component is well factored into property design, construction and valuation.

Originality/value

This is perhaps the first study that uses an objectively derived UNSI to study home rental price dynamics in Nigeria. The study extends knowledge on urban housing price determinants and contributes to literature on the crucial place of security in property management.

Abstract

Purpose

Chinese housing market has been growing fast during the past decade, and price-related forecasting has turned to be an important issue to various market participants, including the people, investors and policy makers. Here, the authors approach this issue by researching neural networks for rent index forecasting from 10 major cities for March 2012 to May 2020. The authors aim at building simple and accurate neural networks to contribute to pure technical forecasting of the Chinese rental housing market.

Design/methodology/approach

To facilitate the analysis, the authors examine different model settings over the algorithm, delay, hidden neuron and data spitting ratio.

Findings

The authors reach a rather simple neural network with six delays and two hidden neurons, which leads to stable performance of 1.4% average relative root mean square error across the ten cities for the training, validation and testing phases.

Originality/value

The results might be used on a standalone basis or combined with fundamental forecasting to form perspectives of rent price trends and conduct policy analysis.

Abstract

Purpose

This paper aims to assess the quality management (QM) principles in facilities management (FM) service delivery for office buildings. This is to create a quality culture that will enhance the performance of FM service delivery towards meeting the users' requirements and needs.

Design/methodology/approach

This study adopts a quantitative methodology via a questionnaire survey for the data collection. In total, 24.41% of respondents from the registered FM companies in Malaysia attended the survey. SPSS 27.0 was used to interpret the collected data, which were then reviewed through descriptive and inferential analysis.

Findings

The study signifies that customer focus, leadership, improvement, evidence-based decision-making and relationship management indicate positive connections with FM service delivery in ensuring a cost-effective working process and meeting both user requirements and legal and regulatory corporate compliance. There are 18 elements of strategic, people and structural barriers that may hinder the implementation of QM in the FM service delivery. Correspondingly, the five main key enablers suggested being teamwork and participation, leadership, continuous improvement, process management and resources and competency development-based enablers.

Research limitations/implications

The study was conducted during the pandemic crisis with limited access and response from participants. However, this in-depth study was still able to synthesize the imperative QM practice in FM among FM practitioners in Malaysia.

Originality/value

This study provides insight into the implementation of QM principles to cultivate a quality culture that will enhance the performance and productivity in FM service delivery specifically for office buildings in Malaysia. Prior to this study, there was a lack of research pertaining to these two themes: QM and FM.

Abstract

Purpose

A novel facet of the construction industry's (CI) digital transformation relates to the rise of smart contracts, and the contribution of blockchain technology in this domain appears to be nascent but rapidly gaining traction. Although the benefits of digitalisation for technologically less enthusiastic CI are irrefutable, the adoption of smart contracts has been found to be low pertaining to industry professionals' behavioural factors stimulated by technological perception. The challenge undertook by this study, therefore, is to develop a knowledge framework for blockchain-enabled smart contract adoption in the CI.

Design/methodology/approach

From a methodological perspective, this study employed a qualitative approach that involved semi-structured interviews with ten (10) highly experienced CI practitioners involved in digital innovations for data collection. Directed content analysis was performed using NVivo 12 software, which enabled the creation of preliminary open codes. Subsequently, these open codes were grouped into similar categories to develop axial codes. Finally, the study presented final themes along with their corresponding descriptions.

Findings

Notably, research findings expanded the current body of knowledge on perceived attributes and their measurement items to determine the perception of innovation adoption in CI, where a total of nine (9) perceived attributes were associated with thirty-two (32) measurement items.

Originality/value

The measurement items were seen as having an extensive impact on the CI professionals' decision to adopt blockchain-enabled smart contracts. With ensuing implications, this study represents one of the first to present a knowledge framework exclusively customised for blockchain-enabled smart contracts, laying the groundwork for effective technological adoption by CI professionals.

Abstract

Purpose

This paper aims to extend the extant knowledge on virtual teams by examining the challenges of virtual project teams in organisations in Nigeria.

Design/methodology/approach

Data were collected through semi-structured interviews. Totally, 20 interviews were recorded, transcribed and analysed. Validity and reliability were achieved by first assessing the plausibility in terms of already existing knowledge on some of the virtual project team issues identified by participants.

Findings

The findings from this study confirmed the growing relevance of virtual project teams in highly competitive global business environments. It emerged that some of the challenges identified in the study had some level of congruence with those previously identified from similar studies from other geographical locations. The findings also suggested that challenges in virtual project teams can be linked to the organisation, the project team and the virtual environment or even a combination of all.

Practical implications

The present study corroborates the position that managing virtual project teams requires additional efforts to attain their objectives through effective communications and the adoption of appropriate technology.

Originality/value

The originality of this study lies in its exploration of virtual project team challenges in a sub-Saharan Africa country (Nigeria). By identifying the challenges associated with virtual project teams, stakeholders will be better able to successfully establish and manage virtual project teams better.

Abstract

Purpose

Over the last couple of decades, many organisations are increasingly adopting virtual team concepts, and construction companies in the Middle East are no exception. Members of a virtual team are geographically scattered and represent a diverse range of cultures. Thus, challenging issues emerge more frequently than in a traditional team. There are challenges associated with space and time as well as high client's demand. Therefore, this study aims to identify and probe the causes of the challenges in virtual project teams in the construction industry of the Middle East.

Design/methodology/approach

A list of challenges was derived through a comprehensive review of relevant literature. Questionnaire survey was conducted with professionals who are involved in construction virtual project teams. Further, the factor analysis technique was used to analyse the survey responses.

Findings

The results show that the challenges in virtual team arrangement in the Middle East construction industry can be grouped into seven categories, namely, organisational culture, conflict within the team, characteristics of the team members, trust within the team members diversity of the team, communication and training, and cohesion in the team. Understanding of these factors will drive the needed platform to support effective virtual project teams in the Middle East.

Originality/value

This study raises the prospect that organisations may establish an environment for team members to achieve higher levels of virtual cooperation by concentrating on these potentially crucial factors. This, in turn, will encourage further innovation and performance within construction organisations.

Abstract

Purpose

The use of technology has increased in the industrial sector over the years. This has propelled the construction industry to follow suit by enhancing construction technology to experience the associated benefits. However, technology adoption in the construction environment has not been smoothly implemented. This article aimed to determine the obstacles to adopting sensing technology in managing construction projects in three major sub-Saharan African nations.

Design/methodology/approach

The study adopted a quantitative approach using structured questionnaires. The questionnaire link was sent to construction professionals in Nigeria, Ghana and South Africa, of which 120 were responded. Data received were analysed using the Statistical Package for Special Science (SPSS) to generate mean scores and the Kruskal–Wallis test and component analysis.

Findings

The results show that construction professionals face herculean tasks when adopting sensing technology in construction project management. Some prominent challenges are initial cost, lack of proper information technology (IT) infrastructure, power supply, lack of well-trained staff, maintenance cost, operating cost, cost of training, technology immaturity and resistance to change. The results also revealed that adoption challenges differ in these three countries, which may be attributable to the economic development level.

Practical implications

Despite the importance of sensing devices in construction industries, the study has revealed that Sub-Saharan African countries face enormous challenges in adopting them in project management and execution. This situation may hinder the industry’s ability to benefit from this technology in terms of efficiency, effectiveness and safety management, which may ultimately affect their cash flows.

Originality/value

The study provides a valuable understanding of the challenges encountered in implementing sensing technology in the construction sector in major countries within sub-Saharan Africa. These findings will enable the countries examined and other African countries to become cognizant of the challenges and implement strategies to overcome them, thereby enhancing performance in the construction industry.
