برآورد اولیه سرعت ساخت و ساز ساختمان در آلمان

The use of a series of independent variables for early estimations of construction speed indicators of German building construction projects is proposed. Based on 200 properties, these variables serve as the speed drivers of a project, and the regression model, tested against the 200 properties, has a mean absolute percentage error of 20%. The identified speed drivers are: project size, number of winters, and planning duration.
