Abstract
Particularly large construction projects are prone to cost overruns and delays. Sometimes it is difficult to foresee the overall cost because of the specifics of such projects.
In some cases even the use of an advanced technology can cause many complications. The influence of local politicians cannot be underestimated, either.
For example, cost forecasts can be deformed to get expensive projects started and many variations instructed that lead to time extensions and additional cost. Unrealistic terms may lead to work being done in haste which can cause further failures and additional cost.
There are some methods to mitigate such risks discussed in this article.
