The cost estimate given in the 2011 road plan for the Rantatunneli project was EUR 185 million excluding the Näsikallio interchange but including provisions for its construction at a later date. The City of Tampere and the Finnish Transport Agency each decided to earmark funds for covering the aforementioned cost with a split of 67%/33%. The split was based on an implementation agreement between the parties (2008).

The Rantatunneli alliance’s report on the development phase (DP) of the project was completed in June 2013. The alliance partners declared their acceptance of and commitment to the results achieved by that point, the project plan and a target outturn cost (TOC) of EUR 180.3 million based on the cost level of May 2013. The owner then decided to progress to the implementation phase (IP), at which point the alliance contract for the implementation phase was signed and the development phase ended. The implementation phase consisted of the construction phase and the warranty period. The construction phase was completed in stages: Stage I in November 2016 and Stage II in September 2017.

The value for money report is designed to demonstrate how well the owner’s targets for the project have been achieved. The development phase of the Rantatunneli alliance project concluded with the drawing up of a value for money report on the development phase.
