Research Report on Condition Assessment of Wood-destroying Damage to Log Walls of a Landless Person's Cottage of Leskovec (orig. No. 70) and a Cottage of Lužná (orig. No. 28) now in the Museum in Rožnov pod Radhoštěm
Kloiber, Michal ; Hrivnák, Jaroslav ; Bláha, Jiří
The subject of the research report was to assess the condition of and identify the wood-destroying damage to the walls of a landless person's cottage of Leskovec and a cottage of Lužná, two log structures that are part of the exhibition at the Wallachian Museum in Rožnov pod Radhoštěm. The report focused on locating points, classifying the degree of damage, determining the extent of concealed attack by the means of non-destructive devices, specifying whether wood is subject to a fungal attack (mycological damage) or insect attack (entomological damage) and drawing the results obtained in the plan documentation. The report was based on direct and mediated visual observation using an endoscope and mainly on measurements taken using a resistance microdrilling device and also on ascertainment of mechanical properties of wood using expanding jaws in the borehole. Based on the results, specific procedures for rehabilitation measures were designed and elements designed for structural rehabilitation were marked in the drawing documentation.

Research Report on Condition Assessment of the Holy Ghost Tower's Roof Frame in Telč
Bláha, Jiří ; Kloiber, Michal ; Frankl, Jiří ; Buzek, Jaroslav
The subject of the research report was to assess the condition of and identify the range of wood-destroying damage to the roof frame of the Holy Ghost tower in Telč focused on locating critical points, classifying the degree of damage, determining the extent of concealed attack by the means of non-destructive devices, specifying whether wood is subject to a fungal attack (mycology) or insect attack (entomology), including the drawing of the results obtained in the drawing documentation of the existing condition of the roof frame. Based on the results, specific procedures for rehabilitation measures were designed and elements designed for structural rehabilitation were included in the drawing documentation. The report is based primarily on direct and mediated (endoscopic) visual observations supplemented by measurements using a resistance microdrilling device.

Reconstruction of a Baroque Open Beam Ceiling Based on Material Analysis
Kloiber, Michal ; Válek, Jan ; Bláha, Jiří ; Čechová, J.
Reconstruction of a ceiling in the north-eastern wing of a former water fortress in Jeseník was carried out during the repair of its roof structure and replacement of the roof. The most damaged parts of the bearing ceiling beams were removed and partially replaced with new timber in the 70s of the 20th C. The way the work was carried out corresponded to the methods and approaches of the cultural heritage protection of that time. The replacement of damaged heads of ceiling beams with new timber that was fitted without connection to the original ceiling beams and only simply hanged on a metal girder can be considered highly provisional from the current perspective. That is why the repair of timber structures of the water fortress included also a reconstruction of the original ceiling system.
