Span by span erection on falsework
If the height and weight of structure permits, segments can be erected on falsework structure. Hydraulic systems are used for temporary support of segments and their alignment. Typically, cranes are used for loading segments onto the falsework support. Nevertheless, if access to the place of loading is limited, VSL has developed alternative solutions for the handling and loading of segments. VSL uses modular support systems enabling fast relocation of support structure to another span of the structure being constructed. Typical erection rate achieved by VSL is one span per three days.
