Abstract
Purpose
Circular economy (CE) is guided by principles, the key being the R-framework. All R-frameworks have a hierarchy. Although several studies have prioritized these principles, there is still an urgent call for country-specific prioritization. This study prioritized circular economy (CE) principles among Ghana's built environment (BE) professionals.
Design/methodology/approach
An explanatory sequential mixed methods approach was adopted. Six principles of CE were identified through a review of related literature and incorporated into a questionnaire. In total, 162 questionnaire responses were received. The quantitative data were analyzed through descriptive and inferential analyses. The data were further validated via semi-structured interviews with eight interviewees of different professional backgrounds in the BE.
Findings
The findings revealed that BE professionals in Ghana highly perceived CE principles as important. The findings further revealed the order of prioritization of the CE principles as follows: (1) recycle, (2) reuse, (3) repair/remanufacture, (4) renewable energy usage, (5) redesign and (6) reduce. To further elaborate on these prioritized principles via the qualitative phase, the interviewees agreed to and confirmed the importance of the identified principles through their verbatim comments.
Originality/value
Although there is a growing interest in research regarding CE in the Ghanaian construction industry, its principles have yet to be prioritized and ranked by professionals in the Ghanaian construction industry. This study unearths why, in terms of prioritization of the CE principles, the construction industry in Ghana does not follow the well-known hierarchy (i.e. reduce, reuse and recycle) in the order of high to low level of circularity.

Abstract
Purpose
This study aims to examine the strategies that can be adopted to enhance the practice of circular economy (CE) principles among built environment (BE) firms operating in the Ghanaian Construction Industry (GCI).
Design/methodology/approach
A structured questionnaire survey was used to solicit the views of 162 BE professionals working in construction, consulting, and developer firms on the issue under investigation. The questionnaire was developed through a review of related literature and complemented with a pilot review. Data were analysed by descriptive and inferential statistics.
Findings
The findings revealed four major categories of strategies (i.e. systems and technical related strategies, market orientation and operational strategies, knowledge dissemination and awareness-related strategies, and environmental and regulatory strategies) to promote the practice of the principles of CE among BE professionals in the GCI.
Originality/value
This study’s findings provide insights into an under-investigated topic in the construction industry, especially, in a developing country such as Ghana, and offer new and additional information and insights into the current state-of-the-art on CE implementation.

Abstract
Purpose
This study examines the level of awareness and practice of the principles of circular economy (CE) among built environment (BE) professionals in Ghana.
Design/methodology/approach
A structured questionnaire survey was used to solicit the views of 162 BE professionals working in construction, consulting and developer firms on the issue under investigation. Data were analysed through descriptive and inferential analysis.
Findings
The findings revealed that the BE professionals possessed moderate awareness of the six CE principles (i.e. repair, recycle, reuse, renewable energy usage, reduce and redesign) examined. The findings further revealed that only two out of the six principles (i.e. repair and reuse) received some moderate level of practice among the professionals.
Practical implications
Practically, the findings would be relevant to government, policymakers, researchers and other construction professionals. For the government and policymakers, these findings would inform them on the laws and policies to enact to increase awareness and practice of CE principles. For researchers, these findings will assist in exploring gaps for further studies. For the construction professionals, the findings would inform them of the need to step up measures to practice the various principles of CE in their firms adequately.
Originality/value
This study provides insights into an under-investigated topic in the construction industry worldwide. It offers new and additional insights into the current state-of-the-art practice of CE principles among BE professionals.

Abstract
Purpose
This paper explores project managers' (PMs') role in contributing to and achieving sustainability within construction projects, particularly focusing on Sustainable Development Goal (SDG) 11.
Design/methodology/approach
Semi-structured interviews were conducted with 15 PMs working with construction firms in the UK. Thematic analysis was also performed on the qualitative data retrieved using the NVivo software.
Findings
The study’s findings revealed that PMs working on construction projects considered various sustainable construction processes in attempts to solve problems with traditional construction technology. Furthermore, it was revealed that the PM’s role was key in achieving the SDGs in general and SDG 11 in particular through the process of perfecting the client brief, ensuring the client’s financial stability and creating an environment of teamwork. In terms of specific competencies, sustainability leadership and sustainable innovative capability were revealed to suggest that a PM is the leader of change.
Originality/value
The study highlights the essential role of the PM in delivering sustainable construction projects as part of the drive to achieve SDG 11. The study impacts the construction industry in developing strategies and training programs that build PMs' competencies and skills for contributing to the world we want.

Abstract
Purpose
This study aims to explore occupants’ perceived importance and satisfaction with high-rise students’ housing facilities’ fire safety considerations (FSCs). The specific objectives are to explore the FSCs for high-rise students’ housing facilities and assess the level of importance and satisfaction with the FSCs provided in high-rise students’ housing facilities in controlling fire outbreaks.
Design/methodology/approach
The study uses an exploratory sequential design with an initial qualitative phase followed by a quantitative data collection phase. Twenty FSCs were identified through the qualitative phase via semistructured interviews. Their importance and satisfaction were revealed through survey questionnaires with 168 respondents who stayed in or were involved in the operation of high-rise students’ housing facilities. Data from the qualitative phase were analyzed thematically, and those obtained from the quantitative phase were analyzed descriptively and inferentially.
Findings
The study’s findings revealed that all the 20 FSCs identified via the qualitative phase and confirmed through the quantitative phase were perceived to be very important in fighting fires in high-rise students’ housing facilities. However, only 9 out of the 20 FSCs received some satisfaction among the respondents in fighting fires in the facilities.
Originality/value
This study offers insight into a rare study area, especially in sub-Saharan Africa. In addition, it grants insight into the occupants’ perspective regarding which FSCs they consider essential and their level of satisfaction with such FSCs in fighting fires in high-rise students’ housing facilities.

Abstract
Purpose
With its impact already felt, the construction industry worldwide is gradually reviving following the lifting up of lockdowns amid the COVID-19 pandemic. Though some articles have been written regarding its impact on the construction industry in other countries, much is yet to be known concerning the current impact in Ghana. This study aims to examine the impact of COVID-19 on Ghana’s construction industry and assess how construction companies are contributing to the fight against COVID-19.
Design/methodology/approach
Semi-structured interviews with nine key professionals working with D1K1 firms currently working on projects of almost similar sizes within the confines of a reputable tertiary institution in Ghana were conducted over a span of three weeks. Thematic analysis was conducted with Nvivo 12 Pro Application software.
Findings
From the findings, the major impact includes: a decrease in work rate, delays in payments and an increase in the cost of materials arising from border closure. On the measures by construction companies in contributing to the fight against the pandemic, findings indicated: educating the workforce on the virus, the provision of PPEs, regular and effective checks on entry and exit from the site.
Practical implications
The study is significant, as knowledge of the impact posed by the pandemic will provide some idea of the measures to put in place to ensure the gradual to full recovery of the industry.
Originality/value
The originality of this study lies in the fact that it is a pioneering study on the impact of COVID-19 on the Ghanaian construction industry.

Abstract
Purpose
The purpose of this paper is to examine the views of construction practitioners on the prevalence of ethical misconduct within the invitation to tender and tender evaluation and award stages of construction contracts in Ghana.
Design/methodology/approach
Following a critical comparative review of literature resulting in the identification of 18 potential misconducts within the invitation to tender and 11 potential misconducts within the tender evaluation and award stages of construction contracts, a questionnaire survey was conducted among 65 construction professionals. Data obtained from the survey were analysed using both descriptive (i.e. frequencies, mean scores and standard deviations) and inferential statistics (paired t-test), followed by gap analysis.
Findings
The findings revealed that corrupt, fraudulent, collusive or coercive practices, client divulging more information to the preferred bidder and inflating tender prices by tenderers in return for kickbacks are key unethical practices prevalent at the invitation to tender stage. Following these key unethical practices, the findings further suggested through gap analysis that submission of bids on non-working days and inadequate time for preparation and submission of tenders were the top two unethical practices that needed serious interventions at this stage. At the tender evaluation and award stage, the findings revealed that interference by influential people in political positions, fake tendering and bid shopping are prevalent. Again, from the gap analysis, interference by influential people in political positions and poor definition of selection criteria were identified to be the two key unethical practices that need urgent intervention at this stage of construction contracts.
Practical implications
This study holds a significant practical implication in the sense that key unethical practices at the invitation to tender and tender evaluation and award stages of construction contracts have been identified, and this provides a suitable basis for stakeholders that spearhead such activities to offer suitable interventions to control such practices.
Originality/value
This study contributes to the body of knowledge as it uncovers ethical misconducts within two important phases of construction contracts in a developing country setting. As there is a continuous effort by the international community towards finding lasting solutions to such misconducts, the findings from this study can be used as a starting point for appropriate policies to be put in place in Ghana to control such misconducts.

This study aims to examine the role of project managers (PMs) in construction health and safety in Ghana.
Abstract
Purpose
This study aims to examine the role of project managers (PMs) in construction health and safety in Ghana.
Design/methodology/approach
Purposive sampling technique was used to select licenced PMs in Ghana where data was collected with the use of structured questionnaires. Mean score analysis, Kendall’s Coefficient of Concordance, Relative Importance Index and Cronbach’s alpha were used to analyze the data.
Findings
The study discovered that most PMs on construction firms in Ghana allocate between 1% and 5% of the total project cost to health and safety. According to the study, client satisfaction is the most important parameter to consider in construction project management. Structural frame, method of fixing and edge of materials were the key design activities that caused PMs to make frequent reference to health and safety. It was revealed that PMs refer to health and safety when confronted by all the procurement-related situations.
Research limitations/implications
The research is limited to the built environment professionals in Ghana. The findings cannot be generalized and extended to other developing countries; however, it could serve as a lesson to them.
Practical implications
The findings of the study are anticipated to provide information about the critical role of PMs in promoting health and safety throughout the project life cycle.
Originality/value
The novelty of the study sought to delve into the complex nature of construction to identify the role of PMs in relation to the health and safety practices in the construction industry.
