7. Drawing PLUMBING-PLAN-BASEMENT-B1 Redacted TL.pdf

This is a Plumbing Partial Plan for Basement B1, prepared by Mortenson for project ZC25. The document is an architectural/engineering drawing that illustrates the plumbing system layout and routing for the basement level of a building. The plan includes detailed schematics showing water supply lines, drain/waste/vent piping, fixture locations, isolation and mixing valve locations, and equipment connections throughout the basement space. Multiple plumbing detail views are provided for specific areas such as Unit B1, showing connections for water heaters, floor drains, and various plumbing fixtures. The drawing incorporates standard plumbing symbols and annotations to identify pipe sizes, materials, slopes, and installation requirements. Sheet notes provide critical construction guidance regarding double check valves for backflow prevention, pressure reducing valves, water temperature specifications, and compliance with applicable plumbing codes. The plan demonstrates coordination between mechanical systems and structural elements, with specific call-outs for proper pipe support, clearances, and protection requirements. This technical document serves as construction guidance for plumbing contractors and installation personnel responsible for implementing the water distribution and waste removal systems in the basement level.
