Building Step jump
The Building Step jump utilizes the Engineers ability to stand on his own buildings in order to reach ledges that are at a medium height. It is executed by simply crouch jumping on top of a building and using the height gained to crouch jump up to the target ledge. While Sentry Guns are slightly taller than Dispensers, for this purpose, Dispensers are often more convenient to use due to a lower metal cost; there is almost no practical advantage to step jumping off of a Teleporter. Contrary to some expectations, the building does not have to be fully constructed or upgraded; the height it gives when stood on is constant, regardless of its animation and level.
