Pre-cast Concrete

Structural frame using pre-cast concrete columns, beams, and/or panels. These may be factory finished internally or externally and could remain exposed in the final building. The extent of onsite work varies between projects. Pre-cast concrete may be used in conjunction with in situ concrete or structural steel as part of a hybrid frame. As early as the 1840s Pre cast concrete elements were used in the construction of some London theatres.
