Health-care building maintenance has been receiving concern because of the recent global pandemic. However, there are inadequate broad studies affecting health-care facilities maintenance and feasible solutions in Nigeria. This study aims to conduct an all-inclusive review of public hospital building maintenance issues and proffer possible solutions to improve maintenance practices in health-care buildings via a framework that will support studies in the future.

A review of published papers from 2006 to 2020 was conducted. Based on the keywords, 3 pertinent databases were searched and descriptions of the findings from 40 studies were recognised and used in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

Two main themes (issues and feasible solutions to improve practices) emerged from public health-care building maintenance practices. The study developed a framework that describes the relationship between issues and possible solutions with an emphasis on how to improve human development, management efficiency, technical competence and professional skills, cost-minimisation and others.

As part of the paper implications, emerged issues were group into five categories (human development, management, technical, limited financial resources and others). The proposed framework for future studies will attempt to mitigate issues and proffer feasible solutions to improve hospital building maintenance practices in Nigeria and other developing countries that are facing similar challenges.

To the best of the author’s knowledge, this paper is possibly the first comprehensive review of public health-care building maintenance practices in Nigeria. Moreover, this review demonstrates how the proposed feasible solutions can mitigate problems.

Adoption of sustainability principles is crucial for construction project delivery, and various parameters are being used as a yardstick for its measurement. This chapter discusses profit as one of the parameters used to determine the success of a sustainable construction project. It explains such issues as the nature and important of construction industry and its product (construction project), meaning of sustainable construction as well as meaning of profit and what its entails in construction. It reviews the value of profit as a measure of success for a construction project and also encourages the need for planning and analysis of all activities involved on a construction project in relation to its environment so as to validate the profit as a measure of project success.

There is growing evidence of a knowledge gap in the association of maintenance with production activities in bottling plants. Indeed, insights into how to jointly optimise these activities are not clear. In this paper, two optimisation models, Taguchi schemes and response surface methodology are proposed.

Borrowing from the “hard” total quality management elements in optimisation and prioritisation literature, two new models were developed based on factor, level and orthogonal array selection, signal-to-noise ratio, analysis of variance and optimal parametric settings as Taguchi–ABC and Taguchi–Pareto. An additional model of response surface methodology was created with analysis on regression, main effects, residual plots and surface plots.

The Taguchi S/N ratio table ranked planned maintenance as the highest. The Taguchi–Pareto shows the optimal parametric setting as A4B4C1 (28 h of production, 30.56 shifts and 37 h of planned maintenance). Taguchi ABC reveals that the planned maintenance and number of shifts will influence the outcome of production greatly. The surface regression table reveals that the production hours worked decrease at a value of planned maintenance with a decrease in the number of shifts.

This is the first time that joint optimisation for bottling plant will be approached using Taguchi–ABC and Taguchi–Pareto. It is also the first time that response surface will be applied to optimise a unique platform of the bottling process plant.

This study proposes a new agenda for research and practice on pro-environmental behaviours in organisational settings by exploring the intersection between technology innovations and pro-environmental initiatives. The goal is to demonstrate the utility of digital technology in promoting and achieving sustainability by addressing the complexity and inconsistency in pro-environmental behaviours.

Using relevant literature on pro-environmental behaviours, this study explores the possibility of embedding technology innovations in pro-environmental initiatives to promote and enhance sustainability in organisational settings.

This study argues that the recent technological advancement and open innovation provide new insights into understanding and implementing pro-environmental initiatives in organisational settings. While pro-environmental behaviours studies have advanced over the past decades, this study shows that many pro-environmental activities do not require employees to change behaviour. According to this study, psychology and technology innovations offer various opportunities for businesses to effectively and pragmatically embed sustainability into their operations without necessarily changing employees' behaviour.

This conceptual study offers opportunities to empirically explore the collaborative nexus between “psychology-based pro-environmental behaviour research and technology innovation”. Despite the plethora of studies on pro-environmental behaviours, results are mixed and inconclusive, raising questions about the dominant practice used for promoting pro-environmental initiatives and behaviours at the corporate level. This study, therefore, provides a new pathway for businesses to address their environmental aspects, demonstrating a pragmatic approach to resolving the complexity of pro-environmental behaviours.

This study allows social investigators, policymakers, and technology developers to re-assess, revive and further investigate how they can collaborate to address practical environmental and social issues.

The sustainability of construction projects has become something of great importance particularly in this era where the natural habitat is going into extinction. The growth in the world population, and series of changes as well as scarcity of resources created a number of environmental and social challenges to the world. Therefore, the concept of sustainability remains the much awaited hope. Companies, corporate bodies as well as national and international organisations are gradually succumbing to pressure to incorporate sustainability considerations into their project decision-making process. This chapter therefore examines the activities of construction industries in connection with sustainability activities in the industry. Different steps to be taken to achieve sustainability in the construction projects as well as the importance of sustainability in construction projects were discussed.

Key performance indicators (KPIs) of maintenance systems serve as benchmarks to workers and organizations to compare their goals for decision-making purposes. Unfortunately, the effects of one KPI on the other are least known, restraining decisions on prioritization of KPIs. This article examines and prioritizes the KPIs of the maintenance system in a food processing industry using the novel Taguchi (T) scheme-decision-making trial and evaluation laboratory (DEMATEL) method, Taguchi–Pareto (TP) scheme–DEMATEL method and the DEMATEL method.

The causal association of maintenance process parameters (frequency of failure, downtime, MTTR, MTBF, availability and MTTF) was studied. Besides, the optimized maintenance parameters were infused into the DEMATEL method that translates the optimized values into cause and effect responses and keeping in view the result of analysis. Data collection was done from a food processing plant in Nigeria.

The results indicated that downtime and availability have the most causal effects on other criteria when DEMATEL and T-DEMATEL methods were respectively applied to the problem. Furthermore, the frequency of failure is mostly affected by other criteria in the key performance indication selection using the two methods. The combined Taguchi scheme and DEMATEL method is appropriate to optimize and establish the causal relationships of factors.

Hardly any studies have reported the joint optimization and causal relationship of maintenance system parameters. However, the current study achieves this goal using the T-DEMATEL, TP-DEMATEL and DEMATEL methods for the first time. The applied methods effectively ease decisions on prioritization of KPIs for enhancement.

This article aims to investigate the various applications of gamification practices in the construction industry, with a focus on improving safety and quality, project management, innovation and productivity and workforce development.

A comprehensive literature review was conducted to identify several construction areas where gamification can be employed, which helped in formulating a questionnaire survey. The survey was disseminated to construction professionals in the Nigerian construction industry using a convenience sampling technique. The collected data were analyzed using a variety of statistical tools such as percentages, frequencies, mean item scores and exploratory factor analyses. Additionally, cluster analysis was performed to obtain a more comprehensive analysis of these application areas.

Four key clusters of gamification areas of application in the Nigerian construction industry were identified – safety and quality, project management, innovation and efficiency and workforce development. By integrating game elements into these critical areas, construction organizations in Nigeria can enhance worker engagement, increase productivity and improve safety, ultimately leading to better project outcomes.

The identification and evaluation of the gamification areas of application in the construction industry would help construction organizations and stakeholders make informed decisions regarding the integration of game elements into critical areas such as safety and quality, project management, innovation and efficiency and workforce development.

The study provides valuable information for construction organizations and stakeholders looking to enhance worker engagement, increase productivity and improve safety in their projects through gamification. It also adds to the growing body of research on the use of gamification in various industries and provides a foundation for further studies in this area.

The purpose of this paper is to work on an analytical approach to test sensitivity of a maintenance‐scheduling model. Any model without sensitivity analysis is a “paper work” without advancing for wider applications. Thus, the simulation of simultaneous scheduling of maintenance and operation in a resource‐constrained environment is very important in quality problem and especially in maintenance.

The paper uses an existing model and presents a sensitivity analysis by utilising an optimal initial starting transportation tableau. This is used as input into the Gantt charting model employed in the traditional production scheduling system. The degree of responsiveness of the model parameters is tested.

The paper concludes that some of these parameters and variables are sensitive to changes in values while others are not.

The maintenance engineering community is exposed to various optimal models in the resource‐constraint‐based operational and maintenance arena. However, the models do lack the sensitivity analysis where the present authors have worked. The work seems significant since the parameters have the boundary values so the user knows where he can apply the model after considering the constraints therein.

The underlying quest for testing the sensitivity of the model parameters of a maintenance scheduling model in a multi‐variable operation and maintenance environment with resource constraints is a novel approach. An optimal solution has to be tested for robustness, considering the complexity of the variables and criteria. The objective to test the model parameters is a rather new approach in maintenance engineering discipline. The work hopefully opens a wide gate of research opportunity for members of the maintenance scheduling community.

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 explore the critical application areas of radio frequency identification (RFID) technology for sustainable buildings.

The quantitative research approach was adopted through a structured questionnaire administered to relevant stakeholders of construction projects. The data collected were analysed with the exploratory factor analysis, relative importance index (RII) and fuzzy synthetic evaluation (FSE).

The study’s results have categorised the crucial areas of application where construction industry stakeholders should focus their attention. These areas are divided into four categories: management technologies, production technologies, sensing technologies and monitoring technologies. The findings from the FSE indicate that monitoring technologies represent the most significant category, whereas management technologies rank as the least significant. Moreover, the RII analysis highlights that tools management stands out as the most important application of RFID, while dispute resolution emerges as the least significant RFID application.

The study establishes the core areas of RFID application and their benefits to sustainable buildings. Consequently, it helps stakeholders (consultants, clients and contractors) to examine the RFID application areas and make informed decision on sustainable construction. Furthermore, it provides systematic proof that can aid the implementation of RFID in developing countries.

The study provides an insight into the possible application areas and benefits of RFID technology in the construction industry of developing countries. It also developed a conceptual frame for the critical application areas of RFID technology in the construction industry of developing countries.
