I want to say the former is "exterior" and the latter is "interior" If it's exterior stone does it go under Div. 04 or Div. 32? Stone Flooring (Interior)would go in Div. 09 as I see it. Julie Cox Root, AIA Senior Member Username: julie_root Post Number: 96 Registered: 02-2004 Posted on Tuesday, November 15, 2011 - 04:26 pm:    I agree with what you outlined. We tend to put the stone paving in Div.04 because we usually are trying to coordinate exterior wall stone.

I want to say Div. 32 - Stone Pavers?

Sometimes the design calls for one continuous floor material to flow from interior to exterior too. Sometimes you should just make MasterFormat bend to your will. As Mark Kalin likes to say, there are no spec police. - J. Peter Jordan (Unregistered Guest) Unregistered guest Posted on Tuesday, November 15, 2011 - 05:21 pm:    There are Division 09 Sections listed in MasterFormat for stone paving and facing that is "interior" stone flooring and wall facing (including "trim" pieces such as base and threshold). Although this may be confusing, I would suggest that the difference is exposure to weather and load. Exterior stone paving may be subject to the weather and vehicular loads (like any paving) as well as pedestrian loads. Interior stone flooring is generally "lighter" in service and not usually subject to weather. These differences in performance which may affect material choice as well as installation materials and methods should lead one in an appropriate direction. This does not mean that it is simple. Adhered stone veneers (thin stones that are not thin enough to be tiles) are an example of an application that would seem to be more appropriate to an interior (Div 09) application, but is found in Div 04. One might specify almost exactly the same material and installation method for an interior wall facing in Div 09. Div 04 does seem to be more oriented to vertical exterior applications. Div 09 sections are for horizontal and vertical interior applications. Div 32 for horizontal exterior applications. What is really confusing is that there are no vertical interior applications for brick unit masonry in Div 09. So, instead of "bend it like Beckham," we should follow Lisa's admonition to "bend it like Kalin."

Although far from perfect I had to call pencils down and decide. We ended up with: Section 04 42 16 - Veneer Stone Assemblies: --Exterior 2cm and 3 cm veneer stone with mechanical anchors. --Interior 2cm veneer stone with adhesive setting on cement plaster. --Interior stone cladding on a monumental stair, including dimensional treads and 3cm trims with a combination of mechanical fastening and mortar setting. --Exterior stone cladding on exterior fountains, and built-in benches and tables including stone tile, dimensional stone and even river rock set in concrete for the water to run down. Section 09 32 23 - Mosaic Artwork Paving: --A stand alone Section for an artist's exterior mosaic pavement. At Bid we were not confident we we even knew what materials they would use. Section 09 32 33 - Stone Paving: --Interior Mortar Set dimensional paving of several types. --Exterior Mortar Set dimensional paving of several types. --Interior Mortar Set dimensional paving set into saw cut depressions in polished concrete floors. All of the exterior was within a courtyard surrounded by the building, so I was not too worried about Div. 09 versus 32. If I was presented with all of the materials and installation types at the get go I would have created a greater number of distinct Sections but that wasn't an option here and I had already created and then tossed nice Sections due to the shifting landscape. The monumental stair in 04 42 16 uses the same stone as a flooring type in 09 32 33, but that is the only instance where we needed to call out a "single sourcing to match" requirement for stone materials specified in more than one Section.

And, for the most part, the creativity is a joy. The other part is the challenge to put that creative design into words that are clear, concise, well, y'all know the rest. Peter, I love "bend it like Kalin". That should be our motto every time we run up against that new application or new material (and if you're watching, there are a whole bunch of new materials waiting in the wings to be incorporated into our built environment) Steve, well done!

Thanks!

As it turns out, we eliminated the exterior stone section for now. Here's my read on the whole thing for the future: Div. 04 - Exterior stone cladding (vertical, but it could include the pavers. Section would be called "Exterior Stone" Div. 09 - Interior stone flooring (not pavers) and stone cladding on walls. Section would be called "Interior Stone" Division 32 - Exterior stone (horizontal) including pavers. This would include stone pavers that continue inside the building entrance lobby if they are the same material as the exterior entrance area. Section would be called "Stone Paving" if there are no adjacent walls.
