I think he meant not to expect to see construction from *inside* the park for 12 months... There's a LOT of stuff that'll be built but hidden behind the berm at the back of the Playful Spot... At the most, you *might* see a little corner of something if the angles are *just* right over the backstage gate near Pete's Garage in Toontown Fair.
As for the lifts, they're just generic high-reach lifts, they can be used for any range of maintenance work. In construction sites it's common practice to park them with the boom extended upward to more easily secure them from unauthorized usage, but perhaps maintenance needs to realize they can be seen from inside the park and should be parked in the down position or somewhere else...
