What term describes a concrete element that has been formed and cured prior to placement in the field?

Explanation:
Precast refers to concrete elements that are formed and cured in a controlled environment off the construction site and then transported to the site for placement. This matches the description of being formed and cured prior to field placement. The key idea is the off-site manufacturing and curing, which distinguishes precast from cast-in-place, where concrete is poured and cured in the field. The other terms describe different concepts: a prestressed girder is about internal tensioning to improve performance (it can be precast, but the term emphasizes prestressing, not the curing location), preliminary design is a design phase, and profile simply refers to shape.
