Abstract:
Formed and unformed surfaces (exterior and interior walls, floors, and ceilings) can be specified as architectural concrete. However, the visual inspection criteria—viewing distance and lighting—appear to apply only to exterior walls. It is unclear how to interpret a 20 ft (6 m) viewing distance for a floor or ceiling, and what light to use for an interior visual inspection.
