This is a technical architectural drawing showing drain, waste, and vent (DWV) riser piping systems for a multi-story building. The document is prepared by the U.S. Army Engineer District, Baltimore, and depicts the mechanical systems layout across multiple floor levels (First Floor, Second Floor, and Third Floor).

The drawing illustrates comprehensive plumbing infrastructure including supply lines, waste lines, and vent risers that service the building's sanitary system. The diagram shows the vertical distribution of piping from the basement through upper floors, with detailed annotations indicating pipe sizes, materials, and connection points. Multiple soil stacks (marked as SOIL), vent stacks, and branch connections are distributed across the building plan at regular intervals. The schematic uses standard engineering notation with dimensional callouts and reference markers (numbered circles) corresponding to specific equipment or connection details. The drawing is not to scale and serves as a planning document for construction of the plumbing and drainage systems in what appears to be a federal government building project.
