The essay critically addresses several solutions and strategies for tackling urban inequalities to uphold the recent "right to the 'healthy' city" spatial paradigm based on early social science works by Emily Skinner and Jeffrey R. and then developed as a urban planning component by the interdisciplinary research group Barcelona Lab for Urban Environmental Justice and Sustainability (2019). The authors propose a transdisciplinary approach in dealing with city renewal-regeneration and the safer use of its spaces. The interrelation between urbanism and architecture, including environmental design, mobility, and social relations, among others, would merge to imagine a more ecologically and socially balanced urban milieu. The paper analyses four specific case studies assumed as proper approaches in dealing with the pandemic, critically reflecting on the application of "Superblocks," "Tactical Urbanism," and "15-minute City" concepts by illustrating and comparing their application in three global cities (respectively Barcelona, Beijing, and Milan). In a nutshell, the authors demonstrate that these policies have their crucial feature in being effective applications formulated for different contexts, proposing successful strategies to overcome health, environment, and mobility issues in all the contemporary global cities.

This chapter analyses three strategies proposed to redefine current urban policies to deal with issues inherited from the contemporary city evolution. The case study analysis focuses on applying the concepts of 15-min City, Tactical Urbanism, and Superblock in global cities such as Barcelona, Shanghai, and Milan. Have these cities changed the urban environment and mobility patterns dealing with health, social, and economic inequities? Which have been the impacts of urban regeneration, governance, and inclusion towards achieving the Sustainable Development Goal 11, emphasizing the need for inclusivity and equitability in urban areas? These questions find the answer in three main aspects. First, the regeneration of the existing built environment; second, short-, medium-, and long-term governance issues; third, the concerns about the possible risk of gentrification. An introductive part explains the adopted methodology, follows an analysis of the three case studies, and, eventually, remarks on what we learned. Two are the primary outcomes: a comparison between different global cities and diverse ways to deal with the impacts of people-centered solutions for urban environments and an evaluation of 15-min City, Tactical Urbanism, and Superblocks feasible solutions for sustainable urban transition.

The real value of BIM, as a method, is partially undiscovered and require deeper understanding of what real potentialities are and how to take advantage of them in the professional activities. More than ever before the collaboration between engineers, architects and technicians is promoted thanks to BIM. On top of this, the construction industry has realized that the main weakness for decades were the lack of effective communication through reliable and timely channels. Naming BIM, the entire design process should be revised, because we should finally accept that the cooperation, communications and sharing are the seminal elements of the success. This paper, starting with these premise, will present and analyze some good examples of BIM designed projects realised recently in Italy, as the Unicredit Pavilion in Milan by Architetto Michele De Lucchi and the Forti HQ in Pisa by ATIproject that marge smart building processes with environmental targets and a new vision for the urban fabric quality.
