The paper proposes a relatively simple tool to evaluate the precision of the developed FEM model by using the measurements of MEMS accelerometers of a high-rise building during its construction process. It is very important to precisely model the stiffness properties and geometry of the whole building with adequate simplifications in order to choose the correct dimensions of the load bearing elements of the building. The finite element models of two 33 story high-rise buildings were verified against the real high-rise building structure using the experimental data. The two high-rise building fundamental frequencies data were experimentally obtained during different stages of the construction process. The experimentally obtained data were compared with the numerically calculated data to evaluate the precision of the assumptions made during the FEM model creation process.
