Uzročnik nevaljalog stanja objekta i gradiva nije jedino starost objekta. Postoje drugi čimbenici odnosno pogreške koji uvjetuju nevaljalo stanje objekta i potrebu za dodatnim mjerama održavanja i poboljšanja. Ovi čimbenici izravno su povezani s načinom projektiranja i izvedbe odnosno pogreškama koje pri tome nastaju, a čiji uzročnici su sudionici u gradnji. Ove pogreške vidljive su u obliku pukotina, promjene boje i sastava gradiva te samog urušavanja, vrlo brzo nakon završetka objekta. U radu su prikazani primjeri izbora statičkog sustava objekta s ciljem umanjenja mogućnosti nastanka pogreške u završenom objektu. Dodatno, navedene su i objašnjene najčešće vrste istih te su dane smjernice za njihovo sprječavanjeThe time is not the only factor influencing the poor condition of the building and built in
materials. There are other factors or flaws that condition the poor building state and the necessity for
increased measures for maintenance and rehabilitation. Those factors are related to design and
construction process of the building i. e. to flaws made in it, and they are caused by participants in
construction. In a very short time after the building is constructed, those flaws are observed in the form of
cracks, changed material structure and color, up to very collapse itself. In this paper an example is given
about the proper selection of the structural system with aim to reduce the probability of flaws appearance
in complete building. Additionally, the most common types of flaws are stated
