The main aim is to present the corruption level among the key building companies. By key companies we usually mean the companies that realise the biggest, most valuable and most advanced technologically contracts, the companies that are successful in competition with others and successful in cooperation. The ability to cooperate successfully is an important goal of key enterprise. The average medium size building firm employs just 3-4 workers and therefore it is unable to undertake any technologically advanced and valuable orders on its own. The existence of key enterprises is typical for building markets functioning within market economy. They support stability and permanent growth and the lack of them causes chaos.
