Talking with the architect now....not a friendly dude at all.
Few questions after looking at your plans.
1) I would like to use Simpson ABA66 Post base in place of CB66.
Any Base plate will work
2) Column to Deck Detail
Where is the load of each column being distributed to? How are these posts being attached to the structure of the deck? How are they being attached to the porch roof (uplift protection)? They aren't just being placed on top of the decking are they? Further, are the columns you show something inline with a Permacast column or are they ment to be a 4x4 wrapped in 1x trim?
Decking is usually installed after the structure has been erected, therefore the columns are set on the specified 3 X 10 girder and the Double Joists at each end of the Porch. So, the decking must be cut around the columns.
The Columns can be any structural entity the owner agrees with...4X4. .6X6. Wrapped or prefinished column.
Uplift is not a concern because the entire structure weighs enough to keep it down without any hold down hardware. We live in an area of wind shear (side winds)..Not uplift as per Tornadoes.( it is being attached to the house structure)
Architects*design the structural members and what the structure should look like.
Architects do not provide the means and methods of how to build the structure.
That is the job of the Builder.
I will be adding uplift protection, most building departments have I worked with require it and with such a large surface area, I think it would be a good idea.
As far as the columns, the plan does not clearly show the columns being set on the girder, the center lines don't line up in the Section view and the girders are set back further in the Perspective views, so I was unclear as to if landing posts on the girder was the intention. Also if the columns are to set on the double box framing going back on the left and right side, this is not in symmetry with the front of the porch, in which the columns have to to set back to land on the girder and not the box. This changes the drip line in relation to the deck and this will leave no room for trim unless a bunch of blocking is nailed onto the outside of the box to support a large overhang of the decking.
Tom,
Apparently you do not know who Architects are.
If you change an Architects plans without the written authority from the Architect.
The Architect can have the structure torn down.
This is why I am conversing with you over the questions as I would like your input on your design. I am seeing what to me are going to be problems and I need you to address them.
So, that being said could you please elaborate on your column details as I don't see it working as is unless I am missing something.
Simple
Set the columns on the girder.
The columns can rest anywhere on the girder..Has nothing to do with the footings.
The footing spacing is just for convenience .Just like a house..evenly spaced..The girder is the beam ..
same as a footing..can take a post anywhere between the footing columns
I think we are miss communicating here. I don't have that in question. I am more then happy to land ontop the girder, I am just unclear on how you want the left and right sides to land. Just drop them on the double box and add blocking as needed to support the decking? Or would you rather put a double joist further in to land these columns on?
Maybe I will make a quick drawing to make sure I am clear.
