Reading the reference guide, they say the following: "Incorporate permanent entryway system at all high-traffic exterior to interior access points to reduce...", also "employ permanent entryway system at least 10 feet long in the primary direction of travel..." not really sure if this implies, interior or exterior entry mats. It also says "Entryway systems must extend 10 feet from the building entrance intro the building interior" What is the correct interpretation?

10 feet total, exterior place matts should have some sort of cover/protection from the elements but don't need completely enclosed. So you can have 5 feet inside, and 5 feet outside.

We recently saw a comment from a reviewer not saying that it was incorrect but just saying allowing it. Not really sure if all reviewers will give the same feedback though

Victor, what specifically was incorrect / not allowed?
Most projects use matts on the inteiror only, but I've had a few feet worth on the exterior when it's completely covered/protected.

It seems from the conversation above that it is feasible to split up the 10' length requirement between interior and exterior applications. Would it therefore be sufficient to combine a 6' permanently installed walk off matt in vestibules with a 6' roll up matt adjacent to the vestibule? Or, does the 10' need to be one continuous system??

I concur with Mara and Todd's assessment. I did a project a few years ago and asked this same question regarding splitting inside/outside for 10-ft. The response was that the exterior portion had to be protected from the elements. I presume this would be more than a canopy overhead but some sort of side wall protection to deter leaves and dust etc., from accumulating on the exterior portion.

I just got comment from GBCI that the entryway must be located inside the building.
Please see CIR 10098 below:
Inquiry
Where there are physical impediments to locating 10 ft of walk-off mats inside the building, is it acceptable to locate a portion of the mat or grate outside and then the remainder of the required 10 ft inside?
Ruling
The intent for the entryway system (grilles, grates, walk-off mats) is to capture dirt and dust. An exception to the 10 ft length and/or indoor location is acceptable provided your alternative solution meets this intent and is thoroughly justified. Applicable Internationally.
