4.2.4.2 Traveling Falsework

Traveling falsework alleviates some of the problems associated with stationary formwork. This type of falsework, including formwork, is assembled to larger units that can be moved to the next span to be cast. As with stationary falsework, this method requires the site to have relatively level and firm ground to allow movement of the falsework on a wheel assembly. In case the ground conditions are less favorable, using the span-by-span method might be advisable, where the superstructure segments are assembled on erection girders. Span-by-span erection is introduced in the following Section 4.2.4. Traveling falsework is shown in Figure 4-8.
