Failures and Reconstruction

BH055 course is part of 3 study plans

Bc. full-t. program nB > S compulsory-elective Summer Semester 4th year 4 credits

Bc. combi. program nBK > S compulsory-elective Summer Semester 4th year 4 credits

Bc. full-t. program nBA > S compulsory-elective Summer Semester 4th year 4 credits

It deals mainly about the focus of the present state of the buildings, the construction- technical and historic research, identification of failures by the external symptoms and basic methods for their removal. The subject deals with the creation of the drawing documentation of reconstructed buildings. Students will learn about the development of building industry laws in Bohemia and Moravia and about building construction systems and principles at of standards and design regulations.

Learning outcomes

In frame of education, students will learn how to find solutions in the field of reconstruction and modernization of buildings to subject him analyze and use for a particular case in order to avoid errors which may commit when designing buildings. Students will be prepared to design changes and adaptations in existing buildings not only to improve the environment and functional recovery, but also with regard to economic efficiency of operation of the building.


Partition, drawing and designing of building constructions, concrete and masonry constructions, metal and wooden constructions, building equipment, building technology and control.


Partition, drawing and designing of building constructions, principal knowledge of building heat engineering, acoustics and illumination, building equipment, building technology and control.

Planned educational activities and teaching methods

Work on projects, a specific examples of solutions reconstruction by type of failure.

Forms and criteria of assessment

Prerequisite for the successful completion of the course is completion of all the lectures and continuous processing the tasks assigned.


Theoretical and practical experience with geodesic surveying of an existing state of an object, performing of brief technical investigations, identification of defects and failures of building constructions according to extrinsic characteristics, projecting of redevelopment of principal defects and failures.

Specification of controlled instruction, the form of instruction, and the form of compensation of the absences
