Waste management - SUBTERRA
Pokorná, Alice ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
This bachelor work is focused on the waste management of major company implementing in the field of construction work. The teoretical part is addressed in legislation dealing with issue in the Czech republic and the general issue of construction waste. In the practical section provides specific procedures especially as Subterra followed in practice their program works and on which it is implemented. I've explored waste management in practice, not only by legislation. It can be concluded that the company proceed with the implementation of their projects in accordance with the law.

LCA of NATM tunnel stamping method
Pokorná, Alice ; Kočí, Vladimír (advisor) ; Trecáková, Tatiana (referee)
The aim of this thesis was to evaluate the environmental impacts of NATM tunnelling method using the assembly of LCA studies. Construction sector still has large potential for advancement, and therefore is a subject of interest for also for LCA studies. Underground constructions applies more with growing demands for space in infrastructure. If sustainable growth in construction is desired, it's important to have an idea about the environmental impacts of this sector. Sustainable growth requires methods and tools for measurement and comparison of impacts of human activities on the environment. These tools are provided by LCA studies, which also allow a proactive approach. The advantage of LCA is a preview of the entire life cycle of the product, so there is no shifting of problems between the individual stages of the product's life cycle. LCA study of cradle-to-gate type was selected to evaluate New Austrian tunnelling method. LCA study was done for one tunnel, length 850m with cross-section surface of 13,46m2 excavated by the NATM method, realized over the course of 18 months. GaBi 6 software tool was used for making of this study. Results show that the most important emission sources of NATM tunnelling method are production of cement, dumping of excavated material, production of reinforcing steel...
