Pretensioning is typically done at the precaster's plant, where the concrete is cast around prestressing strands that have already been tensioned. This yields a precast, prestressed concrete member. Posttensioning involves tensioning the strands after the concrete has been cast, which can be done on-site or at the plant, but typically yields a precast, posttensioned concrete member.
