In the new hall of the Institute for Materials and Structures, there was a need to control the geometry of the existing crane rails. In this paper, the methodology for determining the geometry of such a complex structure is presented, and the results of the applied method are also presented. The final product, i.e. the examined geometry of crane rails included numerical and graphical analysis of straightness, analysis of parallelism and analysis of horizontality of crane rails.

The Church of the Mother of God at Studenica Monastery in Serbia was estab- lished by the medieval Serbian ruler and founder of his own dynasty, Stefan Nemanja (r. 1169–1196).1 The church is finely proportioned. Sophisticated treatment of wall surfaces additionally enriches the high-quality construc- tion in stone (figure 10.1). Nicely carved architectural sculpture enlivens the church exterior while extensive fresco decoration adorns the interior walls. The building is a single-nave structure, with a dominant square-based domical core and a tripartite sanctuary, typical for Byzantine-rite churches (figure 10.2). Architecturally and structurally speaking, this design is essentially a condensed form of a typical Middle Byzantine church, known as an atrophied Greek-cross church.2 In such churches, as in Studenica church, the lateral arms of the cross are reduced to narrow barrel vaults. Thus, these vaults effectively become mas- sive arches that project from structural piers; the same piers that carry trans- versal arches, which support the domical core of the structure.
