Monorail networks are much easier to build than surface networks. The structural system is concrete, prefabricated off site and erected on support columns, typically with a 6' x 6' base (36 square feet) placed every 100 feetalong the route. Since it is elevated, it removes typical high cost construction elements of surface rail associated with moving underground utilities. The support columns can be constructed with much less ground disturbance. Since it is prefabricated and erected it is easy to Budget costs within 90% of final just knowing the length and route from Point A and Point B.
Monorail systems take advantage of pre-fabricated components that can be manufactured off site in a factory setting that allows for tighter tolerances then trucked to the location when they are needed and then installed quickly by utilizing mobile cranes.
Because of the limited touch points on the ground, its prefabricated components, and ease of construction, monorail can also be estimated with confidence. Budgets can be established within 90% of final just knowing the length and route from Point A to Point B.
