PLUMBING DIVISION 22 00 00

The UVU Standards are provided in CSI format for ease of locating requirements from UVU.

These requirements are in addition to the State of Utah Division of Facilities and Construction Management (DFCM) Design Requirements. In the event of any discrepancy between the DFCM Design and UVU Standards requirements, the Architectural/Engineering Team shall use the UVU Standards over the DFCM Design Requirements.

Items below are not intended to be fully encompassing of all the requirements needed to be specified for the completion of a project and the Engineer of Record shall provide their expertise for full completion. Items below that UVU does not intend to currently give direction on are left to the discretion of the Engineer of Record.
