The purpose of the Project was to identify the most appropriate ways to support innovation in SMEs of the construction sector – a sector, which although highly significant for Europe’s economy and growth, has been little regarded and whose innovation performance is questioned. As an RTD project, CONSTRINNONET tried to understand the mechanism behind successful innovation and to examine ways to improve supporting measures for SMEs of the sector across Europe. As such, the Project was more strategic in nature and less concerned with solutions of limited application.
