Description	Journal: Iop Conference Series: Earth and Environmental Science Engineer is now facing a significant challenge related to the vibration problem in the structure. Building is subjected to the significant dynamic load induced by people will generate the dynamic forces. The objectives of this study are to model a three storey building by using Finite Element Modelling (FEM) and perform the vibration criteria plot on floor at laboratory building due to people walking. A vibration excitation source is generated by people walking at four different points. The Finite Element (FE) analyses such as modal analysis and transient analysis are carried out in ANSYS and the data are further generated via MATLAB (VSATs) software to assess the vibration criteria plot (VC). After evaluation, the vibration criterion of survey laboratory fell under VC-E which contributed to the highest percentage plot which is 40 percent of vibration criterion at the certain points. The maximum Root Mean Square (RMS) curve for survey laboratory is 10 micrometers/sec which fell under VC-C at the certain points. VC-C criterion is the good standard for most lithography and inspection equipment up to 1 micron detail size. Thus, survey laboratory has fulfilled the vibration requirements based on the Gordon standard since the VC-E (less severe) criterion is more suitable to allocate the survey equipment for the certain location. The floor vibration performance is analyzed and compared with the guideline and standard such as Generic Vibration Criteria by Gordon in which the vibration level is under minimum permissible level for sensitive equipment.
