We have been studying the method for calculating the construction period of buildings. In part 3 of this study, we demonstrated the equation to calculate the approximate construction period, in the light of the scale effect of buildings and the self-similarity of construction works. 1) In our conclusion, this-equation of day/m^2 is formularized as form (1). 2) If you wish to calculate the construction period of day more accurately, you should use form (2) and table (3). However, table (3) includes the differences because of the regression coefficients derived from data of buildings constructed. In next part, we will provide more accurate coefficients in form (2) from data of model buildings.
