In many construction projects cost and time overruns occur. Especially when public parties are involved in these overruns this may lead to an image decline for the whole construction industry. Flyvbjerg researched multiple infrastructural projects in 20 different countries and found that roads are in average 20% more expensive than planned and in public transport this is even 45% (van Wee and Cantarelli, 2011). The root cause of cost and time overruns is according to Flyvbjerg (2011) optimism. But there are indicators that can show a forecast of cost and time overruns and processes to limit these overruns. Most importantly for this research; it is assumed that project management methods lead to “project success” in relation to for instance cost and time overruns within different contract models.
