The authors discuss the arrangement of supplementary floors in the rooms of a boiler house in the course of its renovation back in 1988. A structural solution contemplating supplementary floors made of small reinforced concrete slabs resting on steel beams was implemented in the course of renovation. Pursuant to the proposed design solution, reinforced concrete slabs were arranged with their ribs down and leaned upon ribs of metal beams. The findings demonstrate that small reinforced concrete slabs rest both on top and bottom ribs of metal beams. Moreover, patterns of arrangement of slabs different from the design solution were implemented. Some slab ribs looked down while others looked up. Therefore, the implemented pattern of arrangement of the above elements was different from the one specified in the design, and the difference caused different values of load that the slabs were exposed to, and the same about the pre-designed cross sections of slabs. Alteration of design solutions concerning the load produced by reinforced concrete slabs onto metal beams also caused changes in the levels of supplementary floors of the building versus the design solution. This inconsistency can cause difficulties in terms of design associated with any future reconstruction of a boiler house.The analysis of reinforced concrete slabs performed in the course of the research confirms the possibility of their arrangement according to the pattern different from the one specified in the design.
