In Ecuador, construction is considered one of the fundamental pillars of the national economy. Being made up of actors at different economic levels, it involves many people who benefit directly and indirectly from the activity. Currently, due to the COVID-19 virus, this sector has had to suspend its activities. However, biosecurity projects have been implemented to reactivate this activity, considering all the variables present at that time to avoid or minimize the biological risk that in many cases has been lethal for the population. Considering that the purpose of the action research design within a qualitative research is to solve daily problems and improve specific practices, this methodology has been implemented, supported by the participant observation technique and structured interview, the data obtained will be processed by ATLAS.TI. In addition, the risk matrices will be applied, which allows an in-depth analysis of the data obtained and the establishment of pertinent recommendations. Through this research a set of recommendations is obtained that allow to establish improvements in the biosafety protocol in the constructions of Ecuador, guaranteeing the economic reactivation and safety of the workers. When analyzing the international context, in countries such as France, Germany, among others, the restrictions due to the resurgence of COVID-19 have been reconsidered. In the case of Ecuador, if the biosafety protocols were not complied with, the activities of the construction sector would come to a standstill again, possibly generating not only problems in the national economy but also the collapse of the national health system
