Interest towards urban micromobility has been growing lately, and it will now increase further due to the measures used against COVID-19. It is recommended to avoid close contact to prevent contagion. Municipalities have been called to implement wider cycling networks so that people may go to their work place by cycling rather than by using public transport. This paper focused on cycling path design using an infrastructure-building information model (I-BIM). The issue covered was how to connect cost and safety requirements in the first steps of the project. We set a methodology that gives, after identifying the intervention area and defining the available economic resources, the key elements needed to design possible cycle path solutions. It guides the designer step-by-step, starting from basic assumptions related to a cycle path’s location (urban/non-urban), budget (by range), and safety (according to Bicycle Compatibility Index BCI and Bicycle Level of Service (BLOS) index), up to the definition of preferred options in terms of materials to be selected. As a case study, we implemented this methodology in the old city center of Catania in Sicily (Italy), designing a cycle path that connects the city center with the existing cycle path on the coast, while aligning with safety requirements within budget constraints.

The aim of this paper, in line with the 2030 European Agenda and 2021 Italian “Recovery and Resilience Plan” objectives, is to define an evaluation methodology and tool to support public administrations to detect buildings, currently unused or underused, that might be apt for transformation interventions. The focus is on historical Italian healthcare buildings since these show widespread decay and neglect. A five-step methodology has been developed: screening of public assets; classification, evaluation, and identification of buildings, based on the “potential index”; GIS mapping and inventory; selection of buildings for in-depth analysis; BIM digitization and definition of the “transformability index”. In the fifth phase, an evaluation tool is integrated into the BIM software to automatically calculate the transformability index of each building using six indicators: usability, fragmentation, modifiability, roof implementation, external envelope, and window-to-wall ratio. The “transformability index” helps define the most appropriate buildings to intervene with for reuse. Building transformation is connected to construction features and layout organization and it is limited by architectural, structural, and artistic constraints.

Public residential buildings make a large portion of the European existing stock and they quite often require deep renovation interventions. A methodology for setting priorities and targeting regeneration investments should be defined relying on the increasing use of building information modelling (BIM) tools even for managing existing buildings. The aim of this paper is to integrate the evaluation process into BIM Revit software developing a specific plug-in, a Decision support system (DSS) that will help to identify the most appropriate flats to be transformed. It is based on measuring three indicators: Usability, Fragmentation, and Constructive Modifiability. Through their weighted average it is possible to obtain a final transformability score. The proposed approach has been tested on a case study chosen within the 1st P.E.E.P. (1st public plan for council and affordable housing) that has been approved in Rome in 1964. The results demonstrate that the transformability of apartments is related mainly to the Constructive Modifiability indicator and buildings with reinforced concrete frames show higher scores. A widespread application of such a methodology on large real estate portfolio may lead stakeholders involved in housing management investments in clear choices related to maintenance of buildings.

Building Information Modelling is the latest phase of a revolutionary process that over the last thirty years has profoundly transformed the world of design in the construction sector in all its different disciplines: architecture and engineering design, mechanical/electrical/plumbing engineering, operation and maintenance, cost and safety, etc. From 2D and 3D assisted design to parametric design, the innovation has led to a profound change of perspective as far as the way of conceiving the work in all its phases is concerned, from concept to execution and consequently to management. BIM methodological approach, based on sharing and interoperability, opens up a potential range of future applications, although nowadays it is mainly used in the MEP (mechanical, electrical and plumbing engineering) sector. One of the most interesting applications can be developed in urban and infrastructural design (Infra-BIM), where the processes and the controls implemented by BIM can be managed effectively and at a higher efficiency level. The term Infra-BIM is used in reference to the adoption of the BIM methodology in the infrastructure sector. An area that by itself calls for a strong disciplinary interconnection with Geographic Information Systems (GIS) and involves many aspects, from the analysis of the area analysed to the relations and interferences with other infrastructures. A multidisciplinary approach that, consequently, requires the correct implementation of the BIM methodology reached by checking the coherence and quality of the information input in the models. The paper focuses on the phase of BIM Validation viewed as a support for a proper work-flow: it not only allows to analyse the whole set of information associated with a parametric object but also how the entire model matches the specific design requirements. BIM Validation process in design is not defined yet, but it is important to aim at a correct procedure so as to guarantee quality of design and future management of the project.
