The challenges confronting the Nigerian construction industry which led to the adoption of supply chain management (SCM) practice were evaluated in this chapter. It was discovered that the Nigerian construction industry is confronted with fragmentation and poor information management. The stakeholders within the Nigerian construction industry proposed the adoption of SCM to overcome the fragmentation and other shenanigans facing the industry. This chapter revealed that construction supply chain (CSC) practices within the Nigerian construction industry focus on waste elimination by adopting the lean concept. The focus on the lean concept could be attributed to the numerous research related to lean or the enormous waste emanating from the Nigerian construction industry. Regardless of the emphasis on lean, the Nigerian CSC is still confronted with fragmentation and heavy waste generation. Thus, this chapter proposed the adoption of principles and technologies driven by the fourth industrial revolution (4IR) is a paradigm shift for the management of CSC in the country. It was discovered in this chapter that Nigerian construction supply stakeholders had not embraced the technologies and principles of the 4IR. The failure to adopt the technologies driven by the 4IR is attributed to the absence of a CSC model that depicts the management of CSC in alignment with the 4IR. This chapter called for developing a SCM model for the Nigerian construction industry in tandem with the principles and technologies of the 4IR.

Built upon theories from outside the construction management literature, this study assesses the impact of product diversification on the performance of construction firms in the UK. Performance was measured based on financial ratios of management performance while diversification was measured by the specialisation ratio. The research involved the use of financial data of construction firms covering the period 1995‐2004. The choice of the period is informed by the economic stability during the period and also, by the fact that diversification is a long‐term strategy. The findings indicate that focused firms outperform both moderately and highly diversified firms based on return on total assets (ROTA) and profit margin (PM). However, no performance difference was found between the moderately diversified and highly diversified firms.

This chapter investigated tendering in stealth construction, emphasising innovative approaches and methodologies that prioritise environmental protection, safety, efficiency, and aesthetics. It began with an overview of the construction industry’s tendering processes, followed by an in-depth examination of various tendering types, including competitive and negotiated methods. The study highlighted contemporary trends such as electronic tendering, Building Information Modelling (BIM), green and sustainable procurement, risk management, data analytics, artificial intelligence, lean construction practices, and blockchain technology. Moreover, with a specific focus on stealth construction, the chapter further analysed certain criteria, including building cross-section development, visibility, radio frequency emission, and countermeasures. It explored integrating functional construction systems, including environmental, safety, health, and quality management. Additionally, it discussed methods like green building, modular construction, and low-impact techniques. Lastly, the chapter emphasised the strategies to achieve environmental protection, safety, speed, economy, and aesthetics in tendering for stealth construction.

In the quest for better construction workforce management, this chapter explored the background of workforce management and related theories, models, and practices. Through a review, the chapter provided meaning to the concept of construction and workforce management. The chapter concluded that while the construction industry worldwide is important to the economic growth of the countries where it operates, the industry’s management of its workforce is challenged by several problems. These problems include the nature of the industry, skill shortage, unhealthy working environment, and poor image of the industry, among others. Also, while the construction industry is rich in diversity, this has been a major source of problems for workforce management. The chapter further revealed that to improve workforce management and attain better-performing construction organisations, careful recruitment, effective training, providing a safe working environment, putting policies to promote diversity, and ensuring innovativeness, among others, are essential.

This study aims to develop a model which incorporates the impact of both aleatory and epistemic uncertainties into construction duration predictions, in a manner that is consistent with the nature/quality of information available about various factors which bring about uncertainties.

Data relating to 178 completed Tertiary Education Trust Fund (TETfund) building construction projects were obtained from construction firms via questionnaire survey. Using 90% of the data, the model was developed in the form of a hybrid-based algorithm implemented through a suitable user-friendly graphical user interface (GUI) using MATLAB programming language. Bayesian model averaging, Monte Carlo simulation and fuzzy logic were the statistical methods used for the algorithm development, prior to its GUI implementation in MATLAB. Using the remaining 10% data, the model's predictive accuracy was assessed via the independent samples t-test and the mean absolute percentage error (MAPE).

The developed model's predictions were found not statistically different from those of actual duration estimates in the 10% test data, with a MAPE of just 2%. This suggests that the model's ability to incorporate both aleatory and epistemic uncertainties improves accuracy of duration predictions made using it.

The model was developed using a particular type of building projects (TETfund building construction projects), and so its use is limited to projects with characteristics similar to those used for its development.

The developed model's predictions are expected to serve as a useful basis for consultancy firms and contractor organisations to make more realistic schedules and benchmark measures of construction period, thereby facilitating effective planning and successful execution of construction projects.

The study presented a model which permits combined manipulation of aleatory and epistemic uncertainties, hence ensuring a more realistic incorporation of uncertainty into construction duration predictions.

The purpose of this paper is to measure the effects of religiosity and advertising on consumers’ patronage of halal industry in Nigeria.

Data for the study was collected using questionnaire survey. The collected data was analyzed using Tobit and ordered Logit models.

The findings of the work show that while the coefficient of religiosity is positive, but it is statistically insignificant, while advertising has a moderate negative effect on consumers’ patronage of halal business in Nigeria.

The study has implication on the use of advertising by halal business. It shows the limit of using advertisement to build brand; advertising shall be used together with other measures such as corporate social responsibility and other charitable undertakings.

To the best of the author’s knowledge, this work is the first of its kind that empirically tests the effect of advertising on patronage of halal business.

The model and existing practice of the construction supply chain (CSC) in the United Kingdom (UK) and Australia was presented in this chapter. The policies and reports that support the practice of the CSC were examined in both countries. It was discovered from the review of literature that the UK has a more detailed report targeted at improving the CSC than Australia. However, both countries have a common factor affecting their CSC which originates from fragmentation experienced within their supply chain. Construction stakeholders in the UK and Australia believe that collaboration and integration are vital components for improving performance. The majority of the contractors in both countries embrace collaborative working for the sole purpose of risk sharing, access to innovation and response to market efficiency. However, most of the models developed for managing the CSC in the UK are built around building information modelling (BIM). Also, the reviewed studies show that supply chain management practice will be effective following the following principle: shared objectives, trust, reduction in a blame culture, joint working, enhanced communication and information-sharing. Finally, the UK has a more established framework and more CSC models compared to Australia.

This study aims to analyze the effect of top management team (TMT) expertise on real earnings management (REM) and accrual earnings management (AEM) activities in companies in Indonesia by examining a hand-collected secondary data from non-financial publicly listed companies in Indonesia in 2016 and 2017. The expertise of TMT members is measured by possession of a master’s degree, understanding and experience of managed core functional areas, and possession of accounting certifications such as CA or CPA. The results of the study show that the expertise of the members of the TMT has no influence on the activity of AEM in companies in Indonesia. Meanwhile, understanding and experience on the managed core functional areas have a positive influence on REM activities through abnormal cash flows. Possession of accounting certification has a positive influence on REM activities in companies that are in accordance with managerial entrenchment effects, as well as a negative influence on REM activities in companies through abnormal discretionary expenses that are in line with incentive-reduction effects.

The purpose of this paper is to investigate and examine whether there is any significant relationship between the extent of business diversification and the performance of construction firms in South Africa. The rationale for the examination stems from the view that the relationship between diversification and the performance of construction firms raises important issues in strategic management and cross‐border business. In contractors' growth however, there is a dearth of empirical research and theoretical arguments regarding the effects of business diversification on construction company performance in South Africa.

The study employed the use of a case study and archival approaches using semi‐structured interviews to elicit primary qualitative and quantitative data over a period of five years for large construction companies listed in Grade 7‐9 on the Construction Industry Development Board (cidb) contractor register. The scope of services and geographic diversification are computed from the sourced data. Dependent variables are the measure of performance using Return on Total Asset (ROTA), Return on Capital Employed (ROCE) and Profit Margin (PM); independent variables used are service/Product Diversification (PD) and Geographic Diversification (GD); while control variables used are size, age, technical capability and capital structure of the construction firms.

It emerged that established construction companies on the cidb contractor registers perform and diversify more in their service/product better than the newly upgraded contractors and this was evident in their performance with respect to profit margin. The results also indicated that there are no statistically significant differences in the performance of diversified and undiversified firms, although diversification was found to have a positive impact on the corporate performance of construction companies.

The outcomes of the research are useful to decision makers and managers of construction companies, as they will help in making viable corporate strategic diversification decisions. The study also engenders a better understanding of the effect of both product and geographic diversification on the performance of contractors.

Affordable housing policies in Turkey have reached a new stage over the last decade in the context of the TOKİ model advocated by the government. Housing developed by TOKİ (the Public Housing Administration), the top official agency responsible for affordable housing policies in Turkey, has become so widespread in all cities of Turkey that it involves not only the construction sector but also trade associations and the public in general. In this article, following a general discussion of the demand and supply of housing in Turkey, we evaluate user satisfaction and the quality of TOKİ implementations since 2000 for low- and middle-income groups in Bursa, the fourth largest city in Turkey. Bursa sets an interesting example for the study because of the city's long-term prominence in commerce and its current status as an important industrial city. Massive migrations and unplanned urbanization have resulted in a need for housing for every income group in Bursa, especially for low- and middle-income groups. The emphasis in this study is that, in addition to quantity, quality should be considered in housing production. Furthermore, the implementation of TOKİ should be aimed at developing more habitable and higher-quality environments by considering all socio-cultural and physical factors. It is expected that these evaluations will lead to the development of a more comprehensive affordable housing policy in Turkey..
