Costs of forming account for about half the value of typical cast-in-place concrete construction. Planning for maximum form reuse can reduce forming costs and provide an opportunity to win bids in competitive markets.

The ability to reuse formwork depends on the nature of the construction. Regular, repetitive structural features favor reuse. Complicated layouts may require many custom revisions. Site layout, phasing of the work, ability to fabricate formwork components, and availability of cranes or other lifting equipment also are important factors.

Opportunities for form reuse are found both on small and large jobs. On small jobs, plywood reuse may be the most important consideration. On larger projects with complex requirements, the choice of forming system and form ties can affect form reuse. Some factors that affect reuse of plywood forms: Edge protection, handling, planning, protection and storage, release agent application, and vibration.
