Rules of thumb can be useful in the beginning stages of planning a maintenance facility. In scoping out your needs, consider the following:
Angle parking can require 20 to 30 percent more land area than 90-degree parking.
On a typical site, approximately half the area is needed for fleet parking and circulation; about a quarter for employee vehicle parking; and only the remaining quarter is needed for buildings.
One acre of land is required for parking 100 cars.
Heavy vehicles require six to eight times as many repair bays as standard automobiles. And the bays have to be twice as large.
