“…We can find references to singular interventions in the foundations of buildings in cases where emergency situations took place, such as those produced by earthquakes, which have put evaluation protocols into place [34] or processes for decision-making in later works [35]. More research has been done when foundations affected by settlements have been in need of repair [36][37][38][39], some of which have meant a leap forward in the study of techniques, processes, solutions and results in real cases [40]. Aspects such as intervention on site, derived costs, or the restoration of buildings in situations of social emergency, have also not been extensively researched or at least not disseminated, given the reluctance to publish technical data that may be liable [40].…”

Having a tool in Spanish regulations to evaluate the sustainability of the construction process in a simple and efficient way (Annex 13 of the Structural Concrete Instruction EHE-08) means an advance with respect to regulations in other countries. However, the complexity of homogenising the conditions that affect the execution of each structure, which are of a very heterogeneous and variable nature, in order to be able to evaluate their contribution to sustainability within the same reference framework, is the greatest obstacle and can have a great influence on the representativeness of the obtained results. However, there are variables that, given their specificity and nature, are not contemplated in this methodology (dust, noise and vibration emission, transportation). This paper proposes a complementary disaggregated model to evaluate the sustainability of variables that are not considered, namely the transportation of materials to the worksite, the commute of workers, the construction process, the emissions of dust, noise and vibrations, as well as the necessary load tests. The results of the application of this model to the real case of the foundations of two singular buildings, show the importance that these previously unexamined variables can have when choosing the most sustainable technical solution in terms of CO2 emissions.
