In Part 3 (The Construction Site), by the barricade that you burn is a metal door and a raised fence. This leaves you right at the next safe room. You may lose up to 80% of your health, so heal up before you leap. On the next building, go to the left corner and jump into the highest branch of the tree below. Turn left, and head to the end, jumping up and to the right to the AC unit / box on the corner of the next building, allowing you to bypass the crescendo event. Head across the fence and jump to the other side of the horizontal fence. In Part 2 (The Crane), jump on the fence by climbing onto the vent cover.
