The article presents the characteristics of pile foundation of an office building and warehouses in North industrial zone of the Bourgas - city in Bulgaria. The foundations are fulfilled in complex geological conditions. The top layer consists of noncompacted embankment from construction waste. Below of the waste is present silty layer practically without bearing capacity. The final layer is clayey soil. In the paper are shown the decisions of the structure engineers, about the features of the foundations and strengthening of the soil. The pile foundations with imbed precast piles are fulfilled. Foundations with precast piles are with only one bearing pile under each column. The mentioned measures are taken to avoid unacceptable settlement of the structure.

Settlement inadmissible for structures would be obtained due to the heavy load storage. Avoided the negative friction with appropriate decision for foundation of the floor structure. In summary is shown the state of the construction to the present date.
