Ecological economics is a multidisciplinary endeavour to connect the social sciences and nature in general. It also connects aspects of ecology and economics to a particular understanding. The created concept centred on the mission to acquire a more advanced albeit better scientific understanding of the complex interconnections between humans, animals and the rest of nature. This is driven towards utilising the obtained knowledge to establish policies that will lead to a more environmentally sustainable world, with a fair resource distribution (both across human groups and generations, as well as between humans, the environment and other species), and also efficiently allocates limited resources such as ‘natural’ and ‘social’ capital. This practice necessitates the development of new methodologies that are comprehensive, adaptive, integrative, multi-scale, pluralistic and evolutionary, while also acknowledging the enormous uncertainties involved.

Offsite construction (OSC) is a modern method of construction (MMC) that involves manufacturing and assembly of buildings. Industry 4.0-driven technological advancements have accelerated OSC uptake causing many skilled construction workers requiring re-skilling or up-skilling. Quantity surveyors currently play an important role throughout a construction project life cycle, and hence, their knowledge on OSC projects is vital for the continuity of quantity surveying (QS) profession. The purpose of this paper is to critically review QS education in an OSC perspective and to propose strategies for up-skilling.

This research includes a detailed literature review of QS and OSC to evaluate how OSC affects the QS profession. Publicly available information on the university websites on accredited QS and construction management degrees was reviewed to identify OSC and MMC references, specifically the content listing and learning outcomes.

Out of the 315 degrees offered by 157 universities, only 69 degrees in 32 universities refer to OSC or MMC. OSC concept is explicitly referred in subjects related to construction technology, production management, lean construction, digital construction and MMC. As such, the research suggests including lean production principles, OSC techniques and design philosophies such as design for manufacture and assembly be added to the QS curricula.

This research is a comprehensive desktop study that does not involve empirical data-based evaluation. Research findings inform strategies to improve QS education and professional competencies.

To the best of the authors’ knowledge, this paper is the first of its kind that evaluates accredited QS degrees and learning requirements in an OSC perspective.

The construction sector (CNS) occupies a very unique position in any economy depending on whether developed or developing economy. The size and linkages of the CNS are expected to be high to help push or pull the economy from developing to developed economy through elaborate forward and backward linkages, a cardinal aim of developing economies. This paper aims to investigate the forward and backward linkages of the CNS in the Nigerian economy.

In contrast to the traditional input–output analysis to assess sectoral economic performance and production interdependence, this paper used econometric techniques, including unit root test, cointegration test and Granger causality test to analyze the data. Time-series data (TSD) for the study were extracted from United Nations Statistical Department database.

The result indicated that the CNS has low forward linkages but high backward linkages to virtually all the sectors of the Nigerian economy. Thus, the outputs of construction mainly satisfy the manufacturing and other activities.

The paper gives an insight into the construction on backward linkages but less extensive forward linkages. The paper recommends a massive local content development of sector to deepen backward and forward linkages and thus helps pull or push weak sectors out of stagnation.

This paper aims to identify the unidimensionality and reliability of 84 factors that influence the performance of construction projects and develop a confirmatory factor analysis (CFA) model.

The study adopted a deductive research approach and started by identifying the positive factors that influence construction project performance. This was followed by the modification of the identified factors. After that, a questionnaire was developed out of the factors for data collection. Exploratory factor analysis was used to establish the factor structure of the positive factors, and this was verified using CFA afterwards. A model fit analysis was performed to determine the goodness of fit of the hypothesised model, followed by the development of the confirmatory model.

The study demonstrated substantial correlation in the data, sufficient unidimensionality and internal reliability. In addition, the estimated fit indices suggested that the postulated model adequately described the sample data.

The paper revealed that performance can be enhanced if stakeholders identify and leverage the positive factors influencing performance. The paper suggests that project stakeholders, particularly government, project owners, consultants and construction firms, can improve project performance by critically examining economic and financial systems (EFS), regulation and policy-making systems (RPS), effective management practices (EMP) and project implementation strategies (PIS).

The contribution of this paper to the present literature is identifying the positive factors and developing the confirmatory factor model. The model comprised 42 positive variables under four indicators: EMP, RPS, PIS and EFS.

The purpose of the study is to elicit risk factors that are peculiar to public-private partnership (PPP)-procured mass housing in Nigeria from the expert perspectives in ensuring the success of the scheme thereby reducing housing deficit in the country.

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.

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.

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.

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.

Managing biosphere reserves (BR) have become more challenging regarding the socio-cultural conflict between communities and BR administrators. For the past two decades, community participation (CP) has become the central narrative for BR management practices in Asia. This paper aims to set out to analyse the current literature because of the paucity of systematic reviews on CP in Asian BR. Also, it proffers possible solutions to enhance biosphere performance.

In total, 31 related studies were identified from the Scopus, Web of Science databases and materials from organisations in the field of practice of territorial conservation. Three themes emerged from the review – willingness to participate, encumbrances and possible solutions.

Factors that influence community willingness to participate in a BR, encumbrances facing the community and possible policy solutions to enhance CP in a BR in Asia were the three themes that emerged from the review. The factors that influence community willingness were categorised into the level of participants in education, perceived waste of time, no confidence of the outcome, okay with current management, land owned, household size and gender factors.

This paper’s recommendations were based on empirical literature reviewed systematically but do not compromise the robustness concerning BR management practices in Asia. It was established that to enrich the findings of this research, regional studies of CP in BR should be conducted, including primary source data using the mixed methods paradigm.

As part of the practical implications, recommendations were highlighted to enhance CP in BR. Also, the paper suggested that BR administrators should have two-way communication mechanisms, cross-sectoral participation and collaboration, implement locally-based solutions through full engagement of community members in decision-making.

This is probably the first systematic review paper on BR management practices in Asia. Filling the theoretical gap via systematic review was part of the significant contribution to CP in Asian BR.

This study explores the opportunities for a gender-inclusive architecture, engineering and construction (AEC) industry, focussing on the gap between architectural education and practice. This study focusses on three research questions: (1) What factors influence women architects' career retention and advancement in the AEC industry? How can practice outcomes be linked with educational approaches for gender inclusion in the AEC industry? (3) What critical factors can enable structural changes in architecture education, including AEC-related subjects and practice/career pathways towards gender equity?

This paper is based on a systematic literature review (SLR). The established timeframe for selecting papers in this study considered the last 20 years, as various seminal studies in feminism and gender inclusion in architecture emerged in the early 2000s through the definition of keywords used in two prestigious databases. The academic articles selected were filtered through a process of inclusion and exclusion, following criteria for suitability and relevance using a Preferred Reporting Items for Systematic Reviews (PRISMA) diagram.

This study revealed key trends in the literature review consistent with the research questions, including (1) the disproportionate struggles women face at individual, interpersonal and organisational levels and the gender-based bias from entry and progression in the AEC industry that also requires multi-level interventions; (2) traditional architecture education affects female students and educators who find networking, social capital and leadership opportunities to challenge gender-based stereotypes and promote workplace equity, and finally, (3) observe enablers for fostering equity in architecture and education, which should not be limited to policy-driven interventions but structural transformations through transparency, mentorship, leadership, awareness raising and empowerment of women and men, promoting inclusivity and gender equity in the AEC industry.

This study considers a global understanding of gender equity in the AEC industry, regional and country-specific analysis needs to be considered in future studies. The study's focus is on women’s inclusion, acknowledging the limitations of conventional binary gender concepts; future studies need to include the experiences of LGBTI + communities and other underrepresented groups. The literature review considers only academic articles; future research should also consider industry reports, government initiatives and organisational documents for a broader understanding of diversity efforts in business.

This paper observes the issues for gender-inclusive architecture within the context of a male-dominant AEC industry through linking architectural education and practice. Studies rarely focus on this link and address workplace issues. This study highlights this link and extends the discussion through the critical literature review, providing a new ground for geographic-specific or intersectional studies.

The substantial benefits of e-procurement to organizations and institutions have, over the past two decades, become central to supply chain management. This study aims to identify the factors that facilitate the adoption of e-procurement system using modified Unified Theory of Acceptance and Use of Technology (UTAUT2).

Using a quantitative approach, the factors identified in the UTAUT2 are operationalized and examined carefully. The investigation has been conducted using a survey questionnaire. The data set has been obtained from 205 construction professionals in Ghana.

The research evinced that the decision by individuals to adopt e-procurement is mainly influenced by performance expectancy and social influence. By implication, the study found out that the respondents are more likely to adopt e-procurement if it is seen to be user-friendly and useful, and when they have a community of people supporting its use. Overall, the findings suggest that the model can stimulate a high adoption and intention to use e-procurement technologies, given its good predictive potential and robustness.

The structures uncovered in the study show that not all UTAUT2 factors are applicable within the study area. The findings provide a good backdrop in the development of policy and a roadmap for e-procurement implementation in Ghana. This is particularly useful for system development and implementation purposes for government agencies, contracting organizations, professionals and users of e-procurement technologies.

The original contribution and value of the paper is the use of UTAUT2 to provide evidence on their significance to e-procurement adoption among construction professionals.

Despite successfully adopting building information modelling (BIM) for design and construction, its adoption in post-construction is critically lagging. This study aims to investigate the adoption of BIM for post-construction in Nigeria. Specifically, it aims to investigate the barriers hindering BIM adoption, propose strategies to facilitate its integration into the post-construction phase and examine the relationship between the barriers and strategies towards adopting BIM for post-construction.

This study employs a quantitative approach to gather numerical data on BIM perceived barriers among International Facility Management Association (IFMA) members. The study also develops strategies from an extensive literature review and combines them with insights from preliminary investigation. The data were analysed using descriptive and inferential statistics.

The top perceived barriers among the professionals are lack of BIM awareness, software availability issues and difficulties using new technologies. Institute training/workshops on BIM software for the professionals in the organisation, including BIM software courses in various related professional exams, and encouraging adoption of BIM from the grassroots, such as higher institutions, emerge as the top strategies. The findings further show a significant relationship between the barriers and strategies, emphasising the recognition that understanding barriers prompts the active development and implementation of strategies.

This study holds originality in its examination of the relationship between the barriers and strategies associated with BIM adoption in Nigerian Architecture, Construction, Engineering and Operation.

The information used for supervision by regulatory departments in public-private partnership (PPP) projects is primarily transmitted and processed by the PPP implementation department, which negatively impacts the information quality, leading to information asymmetry and undermining the overall effectiveness of supervision. This study aims to explore how to use blockchain to anchor the information used for supervision in PPP projects to the original information, to strengthen the oversight.

This paper adopts the principles of design science research (DSR) to design a conceptual framework that systematically organizes information along the information dissemination chain, ensuring the reliable anchoring of original information. Two-stage interviews involving experts from academia and industry are conducted, serving as formative and summative evaluations to guide the design.

The framework establishes a weak-centralized information organizing mode, including the design of governance community and on-chain and off-chain governance mechanisms. Feedback from experts is collected via interviews and the designed framework is thought to improve information used for supervision. Constructive suggestions are also collected and analyzed for further development.

This paper provides a novel example exploring the inspirations blockchain can bring to project governance, like exercising caution regarding the disorderly expansion of public sector authority in addressing information disadvantages and how to leverage blockchain to achieve this. Technical details conveyed by the framework deepen understanding of how blockchain benefits and the challenges faced in successful implementation for practitioners and policymakers. The targeted evaluation serves as rigorous validation, guiding experts to provide reliable feedback and richer insights by offering them a more cognitively convenient scenario.
