The evaluation of geometric changes in special type structures by surveying methods on the example of the Spodek Dome in Katowice

The paper presents an example of surveying field works carried in the main hall of The Entertainment-Sport Hall in Katowice. Both the technology and program of surveying were determined by the main goal that was an evaluation of the main hall construction performance and enablement of periodic observations for displacement evaluation in future. The individuality of presented survey results analysis relates to the structure characteristic and knowingness about primary geometry properties of the construction that was affected by mining.
