The article discusses the possibilities of using forklift trucks (stacker-reach trucks) for mechanized installation of dividing walls, when cast-in-place slabs are assembled or manufactured. It is emphasized that in the early 1980s similar equipment that didn’t have a series production, was used in the construction of buildings by the lift-slab method. Some technical characteristics of the old equipment and modern warehouse equipment are compared, the advantages of the modern are revealed. It is noted that the simultaneous use of warehouse equipment on several floors of the erected frame building can lead to a significant reduction in the construction time. It is also indicated that the stacker-reach trucks used at the construction site are multifunctional, since they can not only transport construction cargo but also serve as an auxiliary equipment for safe work at a certain altitude when performing welding operations and fixing joints.

This paper logically continues the first part of the work describing roof construction with the use of translucent materials. The analysis of the current tendencies in the construction of roofs for sports and entertainment facilities showed that the contemporary studies are focused on the development of sliding roofs and the most recent trends feature façade and roof coatings made of ethylene copolymer and tetrafluorethylene based (ETFE) film. This paper discusses the most prominent advantages of membrane cushion roofing in the light of the summary analysis covering the articles of foreign authors. It mentions that ETFE cushion roofs are also used to restore buildings and structures of historical significance. The paper goes on to suggest a new structure of sliding roof and describes the construction technology taking into account the experience of building ETFE cushion roofs.

The article presents an approach of calculation of evaluation of manufacturer risk to take the wrong decision, based on the results of criticality assessment, received by expert methods of analysis of system reliability in its design stage. The problem of realization of the risk-oriented thought (one of the most important ISO category) is considered. The analytical dependences for calculating risk amount are developed. The dependences take into consideration various probability distributions and cases where the probability distribution is unknown. Using of proposed method allows increase the efficiency of actions aimed at improving of products quality.
