Concrete construction, formwork, cast in place: Gang form now erected above and to right of arch was previously used to cast the concrete above and to left of arch. The entire form module was moved from left to right. The window/door holes on left side were formed by block-outs between the form walls, and they are repeated on the right. A block-out is a rough frame between the exterior forms that prevents cast wet concrete from entering a space. Reinforced concrete structure commercial building at central square of the town of WaterColor, Florida Panhandle, June 2006.
