Typical Work Cycle First Lift

Figure 6.7 shows a typical first lift on grade, using the jump form system in the same manner as gang formwork. The first lift is formed by the framed panel form with its strongback and the com­pression brace. In this case, the wall braces can be anchored di­rectly to the ground or slab for form alignment. It should be noted that a slab on grade or foundations should be available in order to start jump forms from the ground level.
