I know it's a little boring how short this ride is and all, but from a logistics standpoint I can't help but admire how the entire ride is built around two tall structures, with the rest of the track being low to the ground. That means only two points of the construction process requires a tall crane. Maybe you could even get away with having to prepare only two sites for the crane(s) to stand, too. The low-to-the-ground stuff can be done with smaller, mobile cranes. Contrast Hixee's picture of Oz'iriz above, which shows at least four elements where track goes higher than ten meters or so, requiring the builders to move the big cranes around a lot more. That costs a lot of time, which is to say, a lot of money, since renting a crane is expensive.
As far as cost-cutting measures go, it's not particularly glamorous, but it's interesting to see how the ride appears to be designed around the fact.
