“…CIM provides comprehensive information to people managing cities in the form of an urban database that can be constantly detailed and updated, and extends beyond data provided only by geographic information systems (GIS) [ 11 ] or simple CAD. It includes spatial data, and also economic, transportation, underground network [ 12 ], geographical and architectural data, connecting GIS, BIM and the data of smart cities [ 12 ]. Using CIM would be especially useful, given that the 2014/24 European directive in the construction field aims at hitting the target of having BIM [ 13 ] as a standard for all publicly funded construction works by 2025.…”

“…The aim is to make their management more coherent and efficient, since it is both important and complex. CIM allows a unification of multidisciplinary and multi-dimensional [ 12 ] spatial data, which can take care of a vast variety of themes stated in ISO 37120, from which results prove possible automation of 53 indicators out of 100 proposed by the International ISO 37,120 Standard [ 14 ]. Therefore, CIM is an efficient way of management and simulation of a sustainable urban built environment, if applied in practice [ 15 ].…”

Preparing a city for the impact of global warming is becoming of major importance. Adopting climate-proof policies and strategies in response to climate change has become a fundamental element for city planning. To this end, this research considers a multidisciplinary approach, at the local scale, able to connect urban planning and architecture, as a vital base for considering a coastal cities’ ability to control the consequences of climate change, specifically floods. So far, there is a scarcity of research connecting sea ground and land surveys, and this study could become a foundational reference for coastline settlement management using BIM. We found in BIM (Building Information Modeling) a possible tool for managing coastal risk, since it can combine crowdsourced data for geometric and information modeling of the city. The proposed BIM model includes a topography used for 3D thematic maps, a riverbed model, and a waterway model. This model aims to facilitate coordination across separate actors and interests since the urban area model is always updatable and improvable. Focusing on a case study of Lisbon, we developed risk-based 3D maps of the area close to the shoreline of the Tagus River.

City Information Modeling (CIM), on the basis of Building Information Modeling (BIM), Geographic Information System (GIS), Internet of Things (IoT) etc., has incorporated a full-factor spatial model with two and three-dimensional information and data of cities, and therefore, is a fundamental and critical platform for smart city construction. Based on CIM platform, simulation of scheme for city planning and design has brought it to fruition in the following aspects: it can carry out simulation in a world of digital twin to discover experiences and laws, moreover, it can effectively be implemented and executed in this physical world so as to cut costs in terms of trialand-error; and a benign interaction of "virtual vs. real" nature is therefore achieved. From this perspective, the construction and application of CIM platform are of great practical significance to improve the comprehensive city management and operation capability. This research, based on the clarified construction principle and development of CIM, combining with the practice in Guangzhou city, has elaborated the specific application of CIM platform in different spatial scale, such as monomer construction, communities (campus) and cities, and also application at different operating stage, including city planning, design, construction, management and operation. Moreover, this research takes the representative application scenarios of "CIM+Smart Site", "CIM + smart parking" and "CIM + city renewal" into account, based on which, analyses the chief role and its function as guiding framework concerning CIM platform in city management. Stemmed from these efforts, practical experience is therefore summarized, providing reference to further explore extensive "CIM +" application and promote the construction of city information digital platform for related sectors.

While promoting a holistic view of cities, sustainability assessment methods and the circular economy concept have gained attention among urban planners and policymakers. Those methods associated with information technologies can enable intelligent solutions to accelerate sustainability goals. City Information Modelling (CIM) can facilitate the assessment of urban sustainability and circularity. Continuing a previous study, this article examines whether traditional sustainability assessment tools may be adapted to CIM while promoting circular economy practices. Furthermore, the relationship between the most prioritized sustainability indicators and primary urban circularity concerns is examined through theoretical analysis. Therefore, a correlation matrix is proposed and indicators associated with each circularity concern are identified. In total, 24 indicators out of 48 are directly related to urban sustainability. Accordingly, this article discusses how urban circularity concerns can be determined using CIM, based on their correlation with the prioritized indicators. The findings indicate that a CIM-oriented strategy could be used to evaluate urban circularity concerns through sustainability indicators.
