[EN] Nowadays, sustainability assessments tend to focus on the biophysical and economic considerations of the built environment. Social facets are generally underestimated when the appraisal of investment in infrastructure projects is carried out. This study proposes a method to estimate the contribution of infrastructure projects to social sustainability. This method takes into account the interactions of an infrastructure with its environment, in terms of the potential for short and long-term social improvement. The method is structured in five stages:(1) social improvement criteria and goals to be taken into account are identified and weighed; (2) an exploratory study is conducted to determine transfer functions;(3) each criterion is homogenized through value functions; (4) the short and long-term social improvement indices are established; and finally, (5) social improvement indices are contrasted to identify the socially selected alternatives and to assign an order of priority. The method was implemented in six alternatives of road infrastructure improvement. The results of the analysis show that the method can distinguish the contribution to social sustainability of different infrastructure projects and location contexts. This article proposes a mechanism to measure the social efficiency of projects according to the early benefits and potential long-term equitable improvement. This method can be applied prior to the implementation of a project and can complement environmental and economic sustainability assessments. ; This research was funded by the Government of Chile under Doctoral Fellowship Program Abroad (grant CONICYT-2015/ 72160059) and the Spanish Ministry of Economy and Competitiveness along with FEDER funding (project BIA2014-56574- R).

[EN] Assessing the viability of a public infrastructure includes economic, technical and environmental aspects; however, on many occasions, the social aspects are not always adequately considered. This article proposes a procedure to estimate the social sustainability of infrastructure projects under conditions of uncertainty, based on a multicriteria deterministic method. The variability of the method inputs is contributed by the decision-makers. Uncertain inputs are treated through uniform and beta PERT distributions. The Monte Carlo method is used to propagate uncertainty in the method. A case study of a road infrastructure improvement in El Salvador is used to illustrate this treatment. The main results determine the variability of the short and long-term social improvement indices by infrastructure and the probability of the position in the prioritization of the alternatives. The proposed mechanism improves the reliability of the decision making early in infrastructure projects, taking their social contribution into account. The results can complement environmental and economic sustainability assessments. ; This research was funded by the Government of Chile under the Doctoral Fellowship Program Abroad (grant CONICYT-2015/ 72160059) and the Spanish Ministry of Economy and Competitiveness along with FEDER funding (project BIA2014-56574-R).
