The purpose of works was to support the Ourense Town Council in the evaluation of tenders for the award of public service for street cleaning and solid waste collection and transportation within its geographical scope, which comprises just over hundred thousand inhabitants.
Following the structure of specifications for the concession tender, a methodology based on examination and qualification of the technical documentation, and the analysis of the financial offer and administrative documentation were proposed.

Finally, a scheme with a total of fifty-six points to score was reached.

All offers, fifteen in total since several bidders proposed alternative solutions, were scored individually. Once obtained and pooled each score , it was expanded according to specifications criteria so that the best obtained the highest score in each section.
