Respondents provided details about their levels of participation in green and ethical activities, their attitudes towards such behaviour, recent purchase decisions in different product categories, and information use and dissemination. Questions were derived from an earlier piece of qualitative research in which we carried out in-depth interviews with self-identified green consumers and a previous quantitative questionnaire. Our latest findings provide evidence to support varying levels of involvement in green and ethical activities, with differences in participation, attitudes, and information seeking. These differences are discussed and marketing implications identified.

Design/methodology/approach The risk inherent in construction projects had been established through literature in general. The risk in PPP projects is emerging because of the recent acceptance of the procurement option by governments all over the globe. The Nigerian Government has also adopted the procurement option in bridging the housing deficit in the country. This study, therefore, conducts a Delphi survey on the probability of risk occurrence peculiar to PPP mass housing projects (MHPs) in Nigeria. Pragmatic research approach through the mixed method of both quantitative and qualitative methods was adopted for this study. The quantitative method adopts the administration of questionnaires through the Delphi survey, whereas the qualitative method used interviews with the respondents. A two-stage Delphi questionnaire was administered to construction practitioners that cut across academics, the public and the private sectors by adopting convenient sampling techniques and following the Delphi principles and procedures. A total of 63 risk factors were submitted to the expert to rank on a Likert scale of 7 and any risk factors that the mean item score (MIS) falls below the grading scale of the five-point benchmark is deemed not necessary a risk factor associated with PPP MHPs and thereby expunged from the second round of the Delphi Survey. The interview was subsequently applied to the respondents to substantiate the risk factors that are peculiar to PPP-procured mass housing in the study area. Findings The findings show that risk factors such as maintenance frequent than expected, life of facility shorter than anticipated and maintenance cost higher than expected fall below 5.0 benchmark with MIS of 4.64 and 4.55 indicating that the risk factors are not peculiar to PPP mass housing in Nigeria. Research limitations/implications The implication for practise of this research is that these risk factors provide the PPP stakeholders with the comprehensive checklists that can aid in developing PPP risk assessment guidelines in the sector though both partners should be aware of the dynamic nature of risk because new ones might be emerging. Originality/value The authors hereby declare that the research findings are a product of a thorough research conducted in the study area and have not to be submitted or published by another person or publisher and due acknowledgement was made where necessary.

The two 4IR components stand out for their innovative methods that might aid organizations in developing high-performing teams and a culture that is performance-focused. Big data platforms offer methods for methodically eliminating data from data arrays that are too intricate to be used in standard data-processing applications. The Internet of Things and big data are used in every sector. The utilization of big data is significantly growing on a global scale. A staggering number of individuals, including architects, contractors, suppliers, and clients, are now involved in the building process. Large data warehouses are mined for information using big data analysis techniques, which then make the information available to all parties involved. With an overview of IoT and big data applications in the built environment, this research aims to tie current trends to them. In order to identify prior studies on IoT and big data in the construction industry, this study did a bibliometric evaluation and looked at the SCOPUS database. In addition, this probe only allowed recovery of documents from the previous 16 months. Papers based on quantitative, qualitative, and literary reviews made up the majority of the contents. The research also revealed that the bulk of articles were published in industrialized countries. Construction is under underway on phases that will largely focus on IoT research as well as an audit and assessment of the expansion of big data applications. The essay also evaluates and discusses recent advancements in the internet of things and big data industries. Data management, storage systems, automation, and retrofitting are the four main clusters of big data and IoT applications, according to the report. It has been shown that there are several potential when big data and IoT are combined. When properly implemented, such solutions provide professionals and other industry participants in the building sector an accuracy of over 90%.

This duty is essential to the accomplishment of a construction project since it decides whether it will be finished on schedule, on budget, and to the requisite standard. The practice has received several criticisms for failing to correctly carry out her duties. Adoption of contemporary technology like Building Information Modeling (BIM) in its practice has become necessary to eliminate mistakes, inaccuracies, and omissions. However, South African QS practitioners face challenges in implementing BIM. Hence, this study seeks to examine these challenges. A survey approach was utilised. Ninety (90) of the one hundred and fifteen (115) questionnaires that were distributed to quantity surveyors in Guateng Province, SA were returned and considered appropriate for analysis Kruskal-Wallis, percentage, mean item score, and standard deviation were used to analyse the collected data. The results indicate that the main obstacles to the adoption of BIM in QS practice are a lack of BIM competence, a lack of government enforcement, opposition to change, and a lack of client demand for BIM. This study therefore suggests that BIM trainings be given top priority and that the government take the initiative in promoting BIM adoption throughout the nation, especially for public projects.

Th... more In most developed nations, a formal recycling industry oversees the management of solid waste. The opposite happens to be the case in underdeveloped nations wherein, the informal recycling sector has assumed such functions. The informal methods used in Nigeria for managing buildings' end‐of‐life situations has shown in many ways to be compliant with the sustainability goal since they provide an excellent example of how the waste hierarchy may evolve independently, with little or no assistance from policy and regulatory bodies. The purpose of this study is to conceptualise the processes through which salvaged materials from buildings in Kano State, Nigeria is processed in a step‐by‐step manner, ensuring that least amounts of materials end up in a landfill. Adopting a qualitative research design to achieve the study's aim, this study engaged 19 purposively selected experts through semi‐structured interviews in the city of Kano, Nigeria. The collected data was analysed using thematic analysis. Using the biomorphic adaptation of an African snail's shell, the study's findings led to the development of a conceptual model that depicts the actual scenario of handling demolition waste in Nigeria while highlighting the important elements and the inherent interactions among them. Based on these findings, the study recommends that the identified limitations in the Nigerian construction industry be addressed for the purposes of practice improvement and emergence of a comprehensive framework for the sustainable handling of building demolition waste (BDW).

Identifying the main barriers to VM application for ameliorating poor project outcomes in the construction industry is a critical step to overcoming its implementation. Therefore, this study aims to examine the barriers to the adoption of VM in the Nigerian construction industry (NCI) and identify the critical ones for action by construction stakeholders. Design/methodology/approach This study used two rounds of Delphi surveys with 15 VM experts to identify the challenges to VM adoption. The Delphi team’s data from the two surveys were analysed using descriptive statistics. The mean-mode approach was used to identify ten major barriers to VM adoption based on the consensus reached during the second round of the Delphi poll. Following that, an interrater agreement analysis and a significant level analysis were performed. Findings Of the 17 identified barriers hindering VM adoption on construction projects in the NCI, 10 were found to be profound after statistical analyses of the data. The significant barriers include communication gap between the client and other consultants; delay in design preparation because of VM services; the pretext that VM is being practiced in the construction industry; and the wrong perception of VM by construction professionals, among others. The findings of the analysis suggested that the lack of VM adoption in the NCI was because of inadequate knowledge of VM techniques among construction professionals. Therefore, it is advised that VM training be provided for concerned stakeholders to address the lack of VM expertise among Nigerian construction professionals. Practical implications This study investigated the barriers to VM adoption on construction projects in the NCI with the opinions of a few construction professionals who can be regarded as VM experts. As against obtaining large survey responses from construction professionals who may not be knowledgeable in the VM process, the limited VM experts’ responses provide a valid basis for drawing inferences and making recommendations to address the paucity of VM applications in the NCI. Originality/value Through a Delphi survey, the critical barriers to the adoption of VM were identified, along with recommendations to help construction stakeholders overcome the challenges and enjoy the benefits of VM.

However, the rudiments for the effective espousal of such an innovative technology for the delivery of FM tasks have not received scholarly attention. In FM, the business environment is a vital component in achieving organisations’ stipulated objectives. Hence, this study aims to assess the influence of business environment factors in the adoption of CPS for FM activities. Design/methodology/approach A qualitative approach was adopted for the study using the Delphi technique. Experts were selected through a well-defined process that involved certain criteria. The opinions of the selected experts were gotten in two iterations that were subjected to analysis using statistics of measure for central tendency, and interquartile deviation to ascertain consensus among the experts, while Mann–Whitney U test was deployed in checking the difference in the views of the experts. Findings The results from the study indicated that eight business environment factors were of very high significance in determining the espousal of CPS for FM, while the other eight factors proved to be high significance. Also, there was no significant difference in the opinions of experts from academic institutions and professional practice. Practical implications The findings from the study would provide insight to organisations saddled with FM activities on the prevailing business environment factors that would be influential in adopting a digital technology such as CPS. Originality/value The study contributes immensely to the body of knowledge in the quest for digital transformation in FM delivery. It unveils the significant business environment factors that are influential in the drive for incorporating new innovations such as CPS for FM functions.

Achieving sustainability has been a global concern for people of various countries, professions a... more Achieving sustainability has been a global concern for people of various countries, professions and disciplines. In recent years, agencies such as the United Nation (UN) have tailored their goals and objectives to the achievement of sustainability in terms of social, economic, and environmental sustainability. For construction, it has become unavoidable to deliver infrastructures that are economically, socially and ecologically sustainable because of various challenges posed by construction activities such as deforestation, and air pollution, among others.

There have been many management tools for the effective production of infrastructures in the construction industry and one of them is value management. Value management provides a multi-disciplinary framework with the aim of achieving the best function of products and elements at the lowest possible overall cost. It involves the identification of alternatives, and the elimination of unnecessary cost, materials, labour, and energy, while striving to provide the best function of the element. Value management has been applied to construction projects in most developed and some developing economies, while it is barely gaining popularity in some other economies. It is therefore necessary to create an awareness of the benefits and understanding of the various obstacles to its implementation among construction industry stakeholders. It is also essential to understand the various drivers that assist in the implementation of the discipline. This book therefore provides readers with the various drivers, barriers and benefits of adopting value management as well as the medium of application of the tool for achieving sustainable construction projects. There are a number of scholarly books in each of these aspects but there is a lack of literature that integrates the link between the two areas as discussed above.

The book adopts divisions into various parts and chapters to highlight various concepts of value management and sustainable construction, which are collectively referred to as sustainable value management for construction projects. Each of the chapters commences with an introduction describing what to expect from the section and concludes with a summary highlighting major issues raised. As this is a research book, references are provided at the end of each chapter for further reading and expansion of knowledge. An index of important and key words is also provided for a quick reference to areas of interest.

The expected readers of this book include built environment researchers; government agencies (public clients) such as parastatals, ministries and other arms of government that are concerned with the provision of infrastructure and other associated developmental projects; corporate agencies involved in planning, executing and managing infrastructures; individual clients who desire value for money for their projects; owners of construction projects; policy makers who are concerned with improving the performance of construction projects; construction professionals tasked with the responsibilities of development and monitoring of construction works; bodies and boards concerned with the monitoring and regulation of the professionals; building contractors in various categories of project execution in building, civil, and industrial engineering areas; and financiers of construction projects, including banks, insurance companies, bond companies, and loan firms, amongst others. It will also be useful for stakeholders in the construction education sector including education boards; principal administrators of education-related institutions; and researchers in the field of architecture, building, construction management, estate management, engineering, land surveying, project management, quantity surveying, urban and regional planning, and other built environment areas.

The book can be adopted as research guide, framework, aid, note or material for topics relating to value management in construction, the concept of construction projects, project performance indices, and sustainable developments in the construction industry. We hope that all readers of this book will find it not only stimulating, insightful and impacting but also helpful in advancing their knowledge in the areas of value management and achievement of sustainable developments.

While submitting tender, the goal of contracting firms is not only to win the contract but to deliver the project to standard and specifications. In view of this, this study examines factors affecting tender prices submitted by contracting firms in Nigeria. The study also assess various variables influencing their successful delivery of construction projects from the viewpoint of tendering process and procedure in the quest to improving their competitiveness and success rate locally and internationally. Using quantitative design approach, data were obtained through questionnaires administered on registered construction professionals and contracting firms with adequate practicing experience. Prior to the main data collection, pilot study was carried out to ensure proper validity and reliability of the instrument. From the final survey, technical background of the firms is the major determinant of contractors' tender success while the remaining qualitative factors are found to be important as well. To deliver projects successfully after an award of contract, tender period and quality of available information were identified as major influencing factors. In view of this, there is a need for continuous training and development for management and technical personnel of contracting firms for proper sensitization and awareness of the basic factors influencing tender price and project success. More so, for the contractors to remain in construction business, there is a need for innovation and advancement in the use of new and modern technique, process and practices.
