Servei Catala de la Salut of Catalonia, well known as Catsalut, is the Health Department of the Government of Catalonia in Spain. As an urgent action to mitigate the impact of Covid-19, a decision was made to strengthen the health system including the construction of new infrastructures such as polyvalent hospitals. The particularities of these new hospitals are that instead of being isolated in new locations, they were planned to be directly connected with bridges to existing reference active hospitals in the region. In this way, they act as an extension of services to help optimize critical human and clinical resources. The other important point is the urgency for these constructions. A fast-track methodology was implemented and all stakeholders were coordinated with a pioneering concept of strategy. As a result, in a short of time of 20 weeks, the projects had been designed, pre-fabricated, constructed and coordinated.
