"Managing Complexity" - this buzzword hits the nail on the head when it comes to large construction and infrastructure projects. This was also the theme of the CMS Business Breakfast on the topic of Alliancing Contracts that took place on 13 November 2019 at the CMS Reich-Rohrwig Hainz office. This is a new contractual model, which has hardly been used in Austria to date, designed to make projects more cooperative, free of conflict and thus more successful.
