## 1 Introduction
This enables city managers to make informed decisions that optimize resource utilization, reduce waste, and improve service delivery to citizens. In this regard, one tool that has gained momentum by using up-to-date technologies is City Information Modelling--CIM [14,15]. By integrating the different components of the urban environment, the CIM model can help improve planning, designing practices, and implementing sustainable strategies [14,16]. Accordingly, information models for urban spaces, such as CIM, can store and provide data effectively, allowing city planners and urban designers to analyze cities' demands, and make more efficient, effective, and sustainable plans [17]. By incorporating the sustainability analysis criteria into a CIM model, assessments can be more accurate, faster, and easier to manage. Thus, integrating the analysis of urban sustainability into a CIM model can bring great benefits, such as greater adoption of assessment systems, ease of implementation, and present sustainable options as drivers of decision-making. Therefore, this study made a comparative analysis of the internationally well-known systems, focused on identifying the prioritized established aspects and issues, to demonstrate the existing sustainability concerns among the urban sustainable assessment methods. Consequently, the aim is to evaluate the possibility of adopting the most prioritized indicators to the CIM context for assessing urban sustainability, considering the Portuguese methodology SBTool(tm) Urban as a baseline and evaluating how many indicators could be calculated using CIM. The concept of City Information Modelling has gained attention in the literature in the last decade. The number of publications about the topic has been growing year after year, and considering this trend, the expectation is continuing growth [14, 15, 16]. Considering the novelty of the CIM concept, several approaches are presented in the literature. Overall, the concept is linked to urban digital models with rich geospatial information, and a complete and updated database [14, 15, 16, 18]. [PERSON] [17] stated that CIM is analogous to BIM, but on an urban scale. The main idea is to have an intelligent city model, that can assist in the planning, design, and analysis of different aspects of the city. [PERSON] and [PERSON] [19] considered CIM as a computer-based model, involving processes, policies, and technologies, that allow multiple stakeholders to collaborate in the development of a sustainable, participatory, and competitive city. [PERSON], [PERSON], and [PERSON] [20] defined CIM as \"the latest advance from BIM\", where data is available in a 3D environment, including various components of the city. This tool could be used by architects and urban planners, city users, policymakers, and City Councils. All the stakeholders can collaborate and make decisions based on city data. [PERSON] and [PERSON] [21] defined CIM as \"an organic synthesis of a three-dimensional urban spatial model and urban information\". Moreover, the authors highlighted that the CIM concept is closely related to smart cities, integrating the Internet of Things (IoT), Geographic Information Systems (GIS), and Building Information Modelling (BIM), among other technologies. Even though the term CIM is under discussion and there is not a widely adopted concept, it is noticed the relationship between CIM, BIM, and GIS, and many authors investigating possibilities for integration of GIS and BIM to compose a CIM platform [14; 15; 16; 21; 22]. In line with this trend, this study defines CIM as an integration of GIS and BIM technologies. Just as the concept of CIM has several approaches in the literature, there is also no single definition regarding the CIM platform. [PERSON] [23] describes a methodology for using a CIM platform, that it should be open, accessible, and interactive for all users, whether urban planners or citizens. [PERSON] and [PERSON] [19] aligned with this approach emphasizing the collaboration between multiple stakeholders.
