The hot thing in Finland at the moment is the alliance project model. I'm not an experienced expert in the field so I cannot explain it to detail. The newspaper explanation is that the buyer (city council or similar) form a common organisation and share risks and costs. I must admit I was sceptical when it first came up and assumed that either they end up in quarrel or they will find common excuses for the 3-fold costs in the end. But so far I have been wrong. A road tunnel was completed about in time and only exceeding the budget by a relative small percentage (which they explained with added requirements during project lifetime). A tramway project is not complete yet, but so far there have heen only good news about the progress and budget, which is not typical for such a project. This is the marketing explanation by the contractor: https://www.yitgroup.com/en/media/why-is-the-alliance-contracting-model-considered-the-best-approach-to-delivering-the-tampere-tramline-project https://www.yitgroup.com/en/media/why-is-the-alliance-contra...
