You will have to check the detaining to see if it is compliant with 1 or 2. More than likely it is 3 or 4.
Have you tried calling and asking the designing company listed on the sheet you posted?

Agree with Msquared: call the company and ask.
Not sure what your scope is, but I would analyze this carefully. It appears it is a three-hinged arch (based on the fact it is shallower at midspan). In this case, there is thrust involved at the tops of the vertical members. This thrust creates a moment at base of vertical members. The base plate doesn't look like a 'fixed base' condition and I would question if the vertical member, base and foundation were designed properly.

The haunch and peak detail indicate moment connections, so I think it is a two hinged arch. In elevation, Perka calls it "M5400 Frame".
