Abstract

Extreme weathering of some of the sandstone in the superstructure of the Iowa State Capitol at Des Moines has within recent years been a cause of considerable concern. The part of the building affected is that above the level of the basement story, and it is greatest toward the top of the building. Decorations, balustrades, cornices, architraves, pediments, hereafter to be referred to as trimmings and decorations, have been affected to the point where many pieces have fallen and crumbled away. The falling material is a source of danger, the appearance of the building is unfavorably affected, and the monetary damage to the structure is great. Considerable sums have already been spent in removing weakened stone, and in making replacements with cement or other materials, where possible. Certain parts of the exterior are however, apparently continuing to suffer progressive weathering which may be expected to persist and to be a cause of concern and expense. It will apparently be necessary to continue the work of removing weakened stone and of replacing and restoring the missing parts where it is thought to be desirable.
