High-rise buildings are often based on large-diameter bored piles. Their flaws and faults then affect the behavior of the entire building and can significantly influence the statics. Correct processes is therefore necessary to pay attention. The article describes the most common wrong ways of implementing the recommendations and how to prevent them. The design of piles is based on calculated loads, respectively forces and moments acting on the piles and of parameters of the environment. There may, of course, committed a number of mistakes, but we further assume piles to be designed in accordance with all applicable standards. We will focus mainly on technological progress of the implementation of drilling and concreting piles and show the most common mistakes. Bored piles can be performed using a casing or without them. In most cases, the use of casings is possible. Recommendations how to ensure the quality and to protect the environment are also given.
