Cleveland Clinic Design Guidelines: Division 22 - Plumbing

The following pages contain guidelines for the design and construction of new and

renovated facilities at all domestic Cleveland Clinic locations. They shall be used by A/E

firms in the preparation of drawings and specifications for construction of facilities.

The general purpose of each Design Guideline is to provide minimal criteria for

construction materials and equipment at Cleveland Clinic facilities regarding Codes and

FM Global compliance, warranty, approved products, execution, and uniformity.

The Guidelines are not Contract Specifications, but are used to prepare more detailed,

project-specific specifications. The Guidelines are intended to be used to address system

design aspects of equipment that Cleveland Clinic desires to standardize among facilities,

and identify prohibited materials and construction practices.

The use of these Guidelines is mandatory for all design or maintenance projects. Deviations

are discouraged. If project conditions arise which require a deviation, it shall be thoroughly

documented by the user and submitted to Cleveland Clinic for review and approval using

the Design Standard Deviation Request Form.
