Please clarify
The Footing.

Iíve screwed up before, Iíve done this before and all is fine.

Iím sure Iíll get a thrashing for suggesting this.

Most of us with any appreciable amount of experience in any industry have covered our butts with a host of creative solutions. Construction just takes more physical and dynamic fixes.

I have very little doubt that if we were able to lay eyes on the real world problem, you might have at least two or three possible ways out of this. As it stands right now, it is difficult for any of us to suggest 'outside-the-box' thinking because we are really not all that sure exactly what the box looks like.

As I said, we don't really know where and how and to what extent, on which columns you're off. And we don't know your plan of building or if it can be modified.

Think 'offsets' and/or 'cantelievers', and reversing direction on joist layouts, etc. Even enlarging the perimeter to 4 or 6 inches larger to give you space and flexibility to square up the outside rim. Ya gotta get outside the box on this one.

Polk,

Posts are 8' tall, yes beams will sit on top of the posts with Simpson brackets.

Willy,

I am going to re string line the whole space to get more accurate measurements because it's difficult to see them as out of square given that none of the rim joists are 3" away from one post to another.

The shape is a rectangle with one corner lopped off. An exagerated view would be somewhat trapazoidal. There is a 12' side, adjacent to it is a 10' side. Adjacent to the 10' side is an 8' side. On the other end of the 12' side is an 8' side. The two 8' sides are connected by a 40" side.

I have since given some thought to cantilever, but I am concerned that The roof load isn't properly transferred to the footing.

The posts are impossible to move unless I destroy them.
I think there really isn't any solution for making this square that doesn't involve totally starting over.

I think I found out one thing that happened for sure, a couple of the anchors moved during curing, about 1.6 degrees by my calc. I used a square laser to generate two perpendicular lines. It seems that a couple anchors are rotated slightly & a couple footings are off axis by 1" That combination seems to be what has generated most of my errors.

I think my only hope is to start the decking from the centre & work outwards towards the perimeter & fudge the gaps a little bit all the way across. leaving any error to be along the outside edges.

Not sure what else to do. Anyone else got any ideas? I have looked over cantilevering the post to the anchor, but that to me seems like it would weaken the support for the roof.

I will try but I don't think you would see anything. The errors are not obvious when you look at it. I am working on some sketches with dimensions that might give a better picture.

I’d sure like to see a picture of your footings and the wall your building off of in the same shot. Don’t need to see out of square part in the picture.

Yes, get a very accurate centrally located post and work out from that in a star pattern, rather than starting at one end and working around in a daisy chain. This second method adds each error to the one before it.
