Preferred List of Manufacturers (PML) contains specific manufacturers that are acceptable for use on U-M projects. This section is divided by CSI number. When the A/E uses U-M Master Specifications for a project, adding manufacturers from the PML as approved manufacturers in the specification is optional.
For U-M Health funded projects, refer to the U-M Health Preferred Manufacturers Lists.
