The construction sector has been subjected to scrutiny due its propensity for waste generation and the extensive utilisation of finite natural resources. In response these concerns, a transition towards novel conceptual framework known as circular economy (CE) advocated. Nevertheless, integration CE principles within domain encounters numerous impediments advancement. Despite scholarly recognition challenges, scant research devoted elucidating intricacies associated with planning execution large-scale projects, particularly developing nations such Kingdom Saudi Arabia (KSA). This paper intends fill this gap through identification ranking those barriers encountered when trying implement during in KSA. To end, comprehensive literature review was completed, alongside survey conducted amongst 239 participants involved three mega-projects. A statistical analysis data collected carried out based on one-way variance (ANOVA). Following this, relative importance index (RII) established rank 24 categorised major sample. findings revealed lack regulation sector, education training, little awareness guidance subject, absence an incentives policy primary adopting present study endeavours enhance comprehension regarding attendant challenges implementation. overarching objective is provide insights that can inform decision-making processes, thereby facilitating development robust mitigation strategies adoption best practices.

The predominance of a linear economic model and the limited integration circular strategies in design execution building projects—particularly construction sectors developing countries—have resulted ongoing pressure on natural resources, high levels waste generation, reduced productivity, frequent time cost overruns. Collectively, these issues contribute to unsustainable development, adversely impacting social, economic, environmental dimensions sustainability. This study explores perceptions professionals regarding benefits, awareness, implementation Design for Deconstruction (DfD) within Nigerian industry (NCI). Data were collected through structured questionnaire distributed electronically experts Nigeria's South-South geopolitical zone using snowball sampling technique. With 40.10% response rate reliability index above 0.800, data analysed Exploratory Factor Analysis (EFA) Partial Least Squares Structural Equation Modelling (PLS-SEM). Findings reveal that awareness DfD is moderate, but its adoption remains low. EFA identified five key categories benefits: (1) business (2) (3) (4) green certification technology integration, (5) social benefits. PLS-SEM results show all have positive significant influence decision adopt NCI. contributes theoretical advancement practical understanding practices, particularly DfD, with implications reducing waste, improving resource efficiency, supporting achievement Sustainable Development Goals (SDGs) 3, 9, 11, 12, 13.

Adopting circular design strategies (CDS) in building development presents a transformative approach toward sustainability by promoting resource efficiency and reducing environmental impacts. This paper examined the current landscape of CDS adoption, focusing on barriers, enablers, benefits, critical success factors within built environment (BE) Sub-Saharan Africa. Drawing comprehensive review global contexts literature, study identifies categorizes 185 factors, subsequently pruning them to 121 pertinent stage. Barriers such as low awareness, regulatory gaps, economic constraints are explored alongside enablers like leadership commitment, technological innovation, supportive policies. The underscores pivotal role these shaping sustainable practices, emphasizing need for tailored overcome local socio-cultural, economic, challenges BE research contributes nuanced understanding how can be effectively integrated into BE, offering practical implications policymakers, industry stakeholders, researchers striving embrace practices.
