Despite advancements in smart city management through digital representation technologies, operational and accessibility challenges remain in multimodal visualization and integrating high-quality, linked big data within a unified online environment. Key issues include representing irregular geometry in parametric associative design logic, visualizing chronological transformations of heritage buildings, linking procedural Building Information Modelling and City Information Modelling (CIM) processes without advanced programming skills, and ensuring data scalability and lifecycle. This article presents the development of a digital solution for leveraging emerging technologies to monitor and preserve historic clusters in those cities that have yet not digitized their infrastructure. A GIS-based online CIM platform is developed, integrating historical data at an urban scale to support digitally supported management of heritage building stock in ‘as-built’ conditions. The user-centric design facilitates access to point clouds, building databases, BIM models, and environmental analyses. By enhancing data visualization and accessibility, this solution supports city authorities and conservation professionals in sharing multidisciplinary knowledge and informed decision-making. Insights are drawn from two historic clusters in Cyprus. • A novel online platform for multi-scale, multi-discipline heritage data management. • Supports heritage observation, diagnosis, and technical interventions. • Enables neighborhood-scale monitoring for trends and pattern analysis. • Integrates HBIM models with geospatial data for enriched research insights. • Improves efficiency, quality, and cost-effectiveness in historic site management.
