The construction business is widely recognised for its inherent complexity and dynamic nature, which stems from the nature of the job involved. The industry is often regarded as one of the most challenging industries globally in terms of implementing environmental, health and safety (EHS) practices. However, in the absence of EHS, the construction industry cannot be considered sustainable. Therefore, this study aims to identify the trends, knowledge gaps and implications of EHS research to enhance construction activities and knowledge.

The study adopted a science mapping approach involving bibliometric and scientometric analysis of 407 construction EHS publications from the Scopus database with the VOSviewer software. The study is based on journal articles from the Scopus database without restriction to any time range.

The main focus of construction EHS research identified in the study includes sustainability-related studies, risk-related, environmental issues, EHS management, integrated management systems studies, health and safety related and EHS in the construction process. Some emerging areas also identified include productivity, design, culture, social sustainability and machine learning. The most influential and productive publication sources, countries/regions and EHS publications with the highest impact were also determined.

Documents published in the Scopus database were considered for analysis because of the wider coverage of the database. Journal articles written in English language represent the inclusion criteria, whereas other documents were excluded from the analysis. The study also limited the search to articles with the engineering subject area.

The research findings will enlighten stakeholders and practitioners on the focal knowledge areas in the EHS research domain, which are vital for enhancing EHS in the industry.

To the best of the authors’ knowledge, this review-based study is the first attempt to internationally conduct a science mapping on extant literature in the EHS research domain through bibliometric and scientometric assessments.

This study aims to assess the awareness and knowledge level of procurement officers (POs) in Ghanaian tertiary educational institutions regarding sustainability in general and specifically on environmental sustainability in the Public Procurement Act 2003 (Act 663) as amended.

Through purposive sampling technique and face-to-face interviews using semi-structured open-ended questions, qualitative data was collected from 19 POs who are well vested in the procurement profession and willingly agreed to partake in the research. The qualitative data were analyzed using content analysis technique to help organize and elicit meaning from the data collected and to draw realistic conclusions from it.

The results showed that most POs were aware of the Public Procurement Act 2003 (Act 663) as amended, primarily through seminars and workshops organized by the Public Procurement Authority. The interviewees demonstrated a good understanding of sustainable procurement, considering its social, environmental and economic aspects. However, one respondent primarily associated sustainability with only environmental issues. The POs were, however, of the view that the Amended Act 914 (2016) does not give detailed highlights on environmental sustainability, making implementation very difficult, especially regarding the procurement of goods. Overall, the findings indicate a positive level of environmental sustainability awareness and knowledge among the interviewed POs regarding the Public Procurement Act 2003 (Act 663) as amended.

The findings from the study could be used by policymakers to strategize educational campaigns by using the POs’ knowledge and awareness to the implementers of Act 663 (2003) as amended to effectively ensure environmental sustainability in procurement practices. The findings from the study have also contributed to the literature on procurement policy by drawing the attention of policy formulators to give equal attention to all the sustainability pillars, i.e. social, economic and environmental. This would consequently help the implementers to contribute to achieving sustainable development.

This study is one of the few empirical qualitative types of research seeking the views of POs in tertiary educational institutions in Ghana on sustainability and environmental sustainability as enshrined in the Public Procurement Act 2003 (Act 663) as amended. The findings give positive feedback to policymakers on the knowledge and awareness level of the POs on environmental sustainability and highlight the importance of awareness programmes and educational initiatives by the Public Procurement Authority and other stakeholders to ensure compliance with the Act.

Insufficient time allocation for the bidding period occurs, causing drawbacks to both parties, the client and the bidder. Hence, this study aims to evaluate the time allocated for preparing a bid proposal as per the National Competitive Bidding (NCB) in the Sri Lankan context.

The study has adopted a mixed method approach and expert interviews and document review to detect, analyse and validate the issues, and solutions based on NCB along with the adequacy of the allocated bidding period used as main data collection tools. Both qualitative and quantitative data were analysed through manual content analysis and inferential analysis respectively.

Overall, 24 local issues with the existing competitive bidding process and solutions for each were identified. Among the 24 local issues, it was unanimously agreed by all interviewees that three specific issues require attention and improvement. These issues are related to the standard and incompleteness of bidding documents, inaccurate BOQ quantities measured by the consultant or the main contractor, and the excessive number of bidding document amendments by the consultant. It was revealed that a maximum of 42 calendar days (6 weeks) is sufficient for the bidding process while a minimum of 21 calendar days (3 weeks) is insufficient.

The findings of this study would be recommended that Information and Communication Technology Agency (ICTA) understand the necessity of revising the NCB reference to the time allocated for the preparation of bids. By recognising the importance of sufficient time allocation for bid preparation, this research serves as a practical guide for authorities involved in policy formulation, aiding them in implementing revisions that align with the dynamic requirements of bidding procedures.
