Learning outcomes of the course unit

Students learn how to design shallow foundations. Students will be able to design deep foundations for different geotechnical categories. They will be able to design safe and economical sheeting and dewatering of foundation pits. They will learn how to design a suitable method for underpinning of objects at reconstruction and modernization. They will be able to choose the optimal technology for soil improvement.

Prerequisites
