The Bohdanka Lookout Tower

Cooperation with the client and architect since the preliminary design phase resulted in the construction of the tallest timber-frame lookout tower in the Czech Republic. It is an atypical truss frame structure made out of round timber. The tower is 52.2m high with a base size 8.2 x 8.2m and walls inclined at 1.5 degrees. Experts from renowned technical colleges have been involved in the design phase of the project (experimental studies and expert opinions). The structural system has been designed to make the assembly easy and quick as far as possible. These efforts resulted in creating a structural system that comprised ten basic modules. The modules were assembled together using atypical adjustable steel fixture at the carpentry plant on the construction site to eliminate risks related to the works at heights. As a next step, the modules were lifted into position by a mobile crane. The structure undergoes regular inspections and maintenance as a part of our support package during and after the warranty period.
