The article analyses post-contractual behaviour on a sample of 200 randomly selected public works contracts, awarded in 2013, where it was possible to trace information about the final price. The study looks for factors, which have a statistically significant effect on the ratio between the actually paid price and tendered price. The findings are compared with similar studies in Slovakia. The model identifies a number of bids for a statistically significant indicator having a positive effect on the relationship between the actually paid price and the tendered price. Conversely, the ratio between the estimated and actual tendered amounts, as well as the use of subcontractors is seen as the factors with a negative impact.
