Man has never stopped coming up with new ways to make his design more efficient, effective and immediate. During this pandemic, even the construction world had to adapt to find new solutions to continue production in the best and safest way, albeit with changes and a few more constraints. As it can be inferred from the title, the theme of the thesis is very topical and touches on one of the areas that is most affected by this global pandemic: the construction sites. This thesis does not presume to be able to analyse all the economic burdens caused by the Covid-19 in a building environment, as it would be a job full of uncertainties and with too many variables to take into account.
