Division 12: Furnishings

When it comes to meeting furnishing CSI specifications, MasterFormat Division 12 is where you want to look. Unlike other divisions found in the MasterFormat, the products specified in Division 12 are installed or purchased for finished spaces, rather than a building in an unfinished, work in progress.

Being classified as products of art, these items are usable, useful, and also decorative. The furnishings covered in Division 12 include interior and exterior spaces.

MasterFormat Division 12

Though the items in this list are supposed to be things that are incorporated into a building after being finished, there are several exceptions throughout the list. Among them are products that are debatable as to whether a building is truly finished without them.

Countertops and stadium seating could be two item examples that might fall between complete or incomplete lines as far as the structure is concerned.

I hope that this helps you to understand the different things covered in the MasterFormat Division 12. Though there’s a lot covered here, there is still much more incorporated into this Division. However, these items give a good general layout.

If you’ve ever owned an older house, perhaps from the 1800s or very early 1900s, you quickly learn what it was like to be without a standard building and purchasing system. You learn what it was like because you’ll find yourself dealing with the aftermath as you make upgrades to the home.

The MasterFormat’s CSI specifications help manufacturers build items to code and allow builders to prepare a structure accordingly to accommodate the items. It brings organization to multiple steps of any construct.

Engineers, interior and exterior designers, purchasing agents, and construction companies all use and benefit from the CSI MasterFormat. Interior and exterior designers, in particular, benefit from Division 12.
