Structural integrity?
Hello. This is a brand new deck system as of 2 months ago. I noticed that not only were 2/3 horizontal supports off center, but also, 2 joist hangars are snapped.
I live in MN and this is the code requirements

I contacted the builder and he said the support posts didn’t move (despite obvious slide marks) or shift. He also said it was nailed on the end where the broken joists are and it was done so to make it straight.
It seems it isn’t or wasn’t square to begin with and should a single 6” x 6” horizontal support been used rather than 3 2” x 6” ’s?
Vertical and horizontal cracks on wood too?
Thanks for feedback.
Thanks for the feedback all:
Seeing as work needs to be done, several questions:
- What is the best way to lift the deck platform to add/adjust horizontal beams?
- The builder insists the vertical supports didn’t move, what else would explain the misalignment?
- Best way to secure end/mid posts attachment is Simpson Ties?
- Do the 3 horizontal beams need to be bound together?
- Anything else besides the obvious?
Appreciated much!

The triple ply beam is fine and normal.
The problem is that the builder did not correctly connect the top of the post to the beam. Your builder used hurricane ties, which are for joists. That should have failed an inspection. He needs to use metal post caps. You want the BCS2-3/6Z

Have the builder come back and install the post caps.
