Purpose The construction industry faces significant challenges in managing waste and resource inefficiency, contributing to environmental degradation unsustainable practices. Despite the potential of circular economy (CE) practices address these issues, there is limited understanding inadequate policy support for their effective implementation. This study investigates perspectives policymakers on achieving CE Nigerian industry. Specifically, this examines policymakers’ CE, key influencing policies, encountered implementing how policies can transition CE. Design/methodology/approach adopts a qualitative approach explore towards About 50 participants were purposively selected participate provide comprehensive data study. Saturation was attained 34th participants. analysed using thematic analysis identify themes insights. Findings identified gaps hindering policymakers' implementation include financial constraints, resistance change, regulatory frameworks, lack infrastructure, skill weak enforcement mechanisms. Recommendations improvement incentives, updated building codes, enhanced enforcement, mandatory education training programmes increased collaboration between government, academia. A conceptual framework developed promote Originality/value first examine industry, offering unique insights practical recommendations. adds structured practices, research developing countries providing robust foundation future studies expand scope employ quantitative methods measure impact

Frontiers of Engineering Management, Journal Year: 2024, Volume and Issue: unknown

Published: June 21, 2024

Abstract The rapid increase in global urbanization, along with the growth of construction industry, highlights urgent need for effective management and demolition (C&D) waste. Intelligent technologies offer a viable solution to this critical challenge. However, there remains significant challenge integrating these into cohesive framework. This study conducts quantitative analysis 214 papers from 2000 2023, highlighting extensive use artificial intelligence (AI) building information modeling (BIM), geographic systems (GIS) big data (BD). A further qualitative 73 selected investigates seven different intelligent context C&D waste (CDWM). To overcome current limitations knowledge, future research should concentrate on (1) comprehensive integration technology, (2) inclusive studies throughout all lifecycle phases CDWM, (3) continued examination new technologies, such as blockchain. Based insights, suggests strategic framework implementation CDWM. aims assist professionals merging various undertaking lifecycle-wide research, narrowing divide between existing technologies. It also lays solid foundation academic work examine specific conduct comparative studies, refine decisions. Regular updates technological developments are essential stakeholders consistently enhance CDWM standards.

Barriers to Adopting Digital Technologies to Implement Circular Economy Practices in the Construction Industry: A Systematic Literature Review

Published: Feb. 26, 2024

The construction industry is a resource and energy intensive thus, has been criti-cized due to rising environmental concerns. As result of that it gained heightened interest in the concept Circular Economy (CE) over last decade its ability promote slowing, reducing, closing production consumption cycles materials products used practices. Digital technologies hold potential enhance industry's integrate CE However, clear understanding digital technology (DT) related barriers hinder practical implementation CE, appears be lacking within sector. In light this, this study aims identify adopting DTs im-plement practices industry. To achieve aim, systematic literature review was conducted by reviewing twenty-three (23) relevant papers published until January 2024 Scopus database. VOS viewer software perform co-occurrence analysis keywords new popular areas field content analyse major adapt implement identified thirty-four (34) use these were categorized into nine such as: infrastructure, organizational, regulatory, standardization, investment, nature industry, technological, stakeholder data barriers.

Mitigating digital transformation risks for circular construction in emerging economies: an empirical investigation in Vietnam

International Journal of Construction Management, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 11

Published: Aug. 30, 2024

Although emerging economies are increasingly adopting digital solutions, integrating these technologies with circular construction practices remains relatively unexplored, which could impede the sector's transformation. This study addresses this gap by investigating complex risk landscape, identifying 23 critical concerns through a quantitative approach. Utilizing data collected from 248 professionals in Vietnam, scrutinized and assessed risks using reliability testing, Kruskal-Wallis test, exploratory factor analysis, relative importance index, mapping techniques. The results revealed differences how clients, contractors, consultants perceived transformation for construction. In addition, findings indicated most significant risks, including negative returns on investments, income loss, competition, legal uncertainties, cyberattacks, high digitization costs. Furthermore, comparative analysis showed that countries similar socioeconomic cultural backgrounds may exhibit markedly different profiles. Theoretically, work bridges circularity digitalization, offering theoretical insights into dynamics economies. Moreover, practical implications substantial, providing valuable strategies decision-makers stakeholders Vietnam beyond, paving way more resilient sustainable future industry.

Dismantling linear lock‐ins in the Australian AEC industry: A pathway to a circular economy

Sustainable Development, Journal Year: 2024, Volume and Issue: unknown

Published: June 11, 2024

Abstract The architecture, engineering, and construction (AEC) industry has struggled in its efforts to transition a circular economy (CE) due lock‐ins, where the remains entrenched practices that resist this much‐needed transition. solutions implemented so far have been unsuccessful. This failure can largely be attributed prevailing paradigm, which assumes by sequentially removing barriers will naturally follow. However, assessment overlooks “lock‐in” effect of within industry's linear model. A comprehensive, holistic “whole industry” approach is essential uncover these lock‐ins. In context, O'Brien's “three transformational spheres framework” introduced examine how Australia's AEC sector deterred from transitioning CE three groups provide viable recommendation tackle them. Fifteen experts were interviewed, covering dimensions framework. findings specify levels intervention must addressed recommend an order for tackling them: first, political systems structures; second, practical behavioral technical responses; finally, personal beliefs values. article contributes significantly field outlining comprehensive array strategies Implementing discussed potential catalyze long‐awaited transformation industry. advances theoretical framework concerning adoption provides reliable reference policymakers, practitioners, advocates who are orchestrating transformative journey based on principles.
