The objective of this work is twofold: to determine the scope of the tools currently available for the assessment of sustainability of structures in Spanish legislation; and to identify environmental aspects that have yet to be covered, especially in the case of foundations and of measures aimed at the structural rehabilitation of singular buildings. To this end, the method proposed in the Spanish Instruction of Structural Concrete is applied to the particular case of the supported foundations of the Cylindrical and Colonel buildings in the construction of the new Faculties of Law and of Work Sciences, of the University of Seville during the period between 2005 and 2008. This case was chosen for its special uniqueness and for its inclusion of environmental aspects that remain outside the scope of existing methods.
Most of these aspects are also of great relevance in structural rehabilitation activities carried out in urban environments and neighbourhoods, where a major surge is currently underway due to the economic crisis that has hit projects of newly constructed buildings. By virtue of the work carried out in recent years in the field of sustainability and the environment by several research groups at the University of Seville, a number of alternatives are proposed for the quantification of those aspects that remain to be considered. These techniques are based on tools that allow the agents to intervene in a flexible and effective way in the project implementation phase.
