Series K: Drawings

The vast majority of the architectural drawings are construction drawings that include both structural (generally the 1000 series) and mechanical sheets. These sets of construction drawings are mainly for high-rise buildings, and can include as many as 300-400 individual sheets per project. The firm also designed the interiors of many of their buildings and such drawings are well represented within the collection. There are very few preliminary sketches for projects as these were either lost or never retained due to Marshall's working method of using a large blackboard for preliminary studies. Revisions are in the form of small drawings called "pasters."
