Building Information Modelling (BIM) is reshaping the global construction industry by enhancing collaboration, transparency, and sustainability throughout the project lifecycle. In Romania, however, BIM implementation in publicly funded construction projects faces significant legal, institutional, and cultural challenges. This paper examines the current regulatory landscape, focusing on national strategies, public procurement laws, and relevant technical documentation frameworks. Drawing on recent national surveys and case studies, it explores industry perceptions, technical barriers, and the level of BIM maturity. The findings reveal a growing awareness and gradual adoption of BIM, yet highlight persistent obstacles such as limited professional training, unclear legal responsibilities, and high implementation costs. Based on this analysis, the paper provides strategic recommendations for improving the regulatory framework, developing national standards, fostering interdisciplinary education, and accelerating digital transformation across the Romanian construction sector in alignment with EU policies and international best practices.

The 15-minute city concept has emerged as a framework for promoting more sustainable, inclusive, and accessible urban environments by enabling residents to reach essential daily services within a short distance from their homes. This study evaluates potential spatial accessibility to mapped points of interest in the Berceni neighbourhood, a socialist-era residential district in southern Bucharest, Romania. Walking isochrones were generated through network analysis and subsequently indexed and aggregated using the H3 hierarchical spatial system at resolution 10. Accessibility was assessed for seven social functions using three weighting specifications: 1:1:1, 3:2:1, and 5:3:1. The final analysis included 520 mapped POIs and 8465 H3 resolution 10 cells. The results reveal broadly consistent spatial patterns across the three weighting specifications, although the weighting assumptions influence local scores, the extent of high-accessibility areas, and the relative ranking of individual H3 cells. Caring has the largest mapped opportunity count and broad spatial coverage, whereas working and governing are the least represented functions and display comparatively low potential accessibility in several parts of the neighbourhood. A function-targeted scenario involving the addition of a childcare centre in the south-western part of Berceni produces a local improvement in working accessibility but does not eliminate the wider functional deficit. The findings demonstrate the applicability of combining network-derived isochrones with H3-based spatial aggregation for neighbourhood-scale accessibility assessment.
