what is best way to design an exhasut shaft on an exterior restaurant wall?

Question

I have a restaraunt on the bottom floor of a 3 story building. I need to run my exhasut ducts to the exterior wall and up to the roof.
The vertical run will be 42' +/-. the shaft will be 3' x 2' interior dimension.
The exterior wall is 3 coat stucco on metal lath over building paper over densglass gold over 6" metal studs.

What will be teh best design/ framing method to construct this shaft? This will be built in Florida- are there any code violations by running an exhasut shaft up an exterior wall?

Where will be teh best place to find details?

Thanks.
