There are public entities that possess in their hands multiple property assets, that are difficult to manage, being, in many cases, buildings that are considered icons that contribute to the character of their surroundings or that take part of our historical heritage or have some kind of protection. It is difficult for the private sector to manage these assets, if in the public sector, we add the electoral cycle, the problems increase. At a public level, it is more complicated, since it should be understood that the planning of property assets and delivery do not correspond to the political cycles. In addition, policies change once established, perhaps with the development under construction, will inevitably have serious consequences on: the planning, cost and alignment of the building with the final needs of the asset. Therefore, it is important for all the stakeholders to realize that an approach is needed for the long-term management of property asset portfolios. To achieve this goal, we have developed a structured and programmed approach of Property Asset Management adapted to the public sector, in order to provide the best solutions.
