The Mayor of Porto Alegre, Jose Fortunati, announced on 15 April 2013, that a new PMI (Proposta de Manifestação de Interesse or Request for Expressions of Interest) will be launched for the Feasibility Studies of the metro system.

The announcement comes after the analysis of two studies submitted for the first PMI were not satisfactory. Two studies were submitted on February 7, 2013. One was submitted by Brusten PM and was discarded because it did not comply with the requirements. The other proposal was submitted by Invepar - Odebrecht and it estimated the construction costs as if carried out by deep digging.

Although this last option would cause less impact on mobility the costs are not feasible.  The construction of the subway will be done with the cut and cover method, said the Mayor. The city has a budget of R$ 3.085 billion and the amount estimated by the Invepar-Odebrecht consortium was R$ 9.5 billion.

The new PMI will demand that the construction method is cut and cover.
