We have developed digital models of all the elements that make up a gas station: the control room building, the canopy over the gas pumps, pumps, fuel tanks, drainage tanks, landscaping elements. We can change the model of the control room and sales area from option 1 (80 m2) to option 2 (60 m2) or option 3 (20 m2). We can change the model of a canopy for three petrol pumps to a canopy over two petrol pumps. After all the changes made, we automatically receive design documentation for the complex of structures that make up the gas station.
