Stand alone hot tub deck, is it sufficient?

Here's the 8x8 deck I constructed to hold my hot tub. Is this construction sufficient to hold this load?

9 10" footings with 6x6 posts, three triple 2x10 beams and 2x10 joists at 12" on center. Cross bracing is 2x6.

Should I add more cross bracing?

Welcome to the forums! Structurally it appears strong enough. Your cross bracing must be bolted through. I can't tell from the picture. How are your joists attached to your beams? I don't see any connectors, and they can't just be nailed.

How are you gonna get in the tub? Slide off the roof? Just kiddidng. I am sure you have a plan.

Chandler, thanks for the reply!! I'll attach another picture of the connections, they are attached to the beams with hurricane straps.

As far as getting the hot tub up there.......good question! LOL!!! I was thinking about constructing a ramp out of a couple 2x10's, and with the help of a half dozen guys, man handle it up on the platform!

The Egyptians built the pyramids, so you can do it Not wanting to nitpick you by any means, but doing this for a living certain things bring up questions. It appears the post-to-beam connectors may be held with roofing screws. If so, they may not be compatible with the pressure treated wood. Simpson Strongtie screws or nails which are HDG would be better if that is the case.

Thanks for the tip! I used up all my Simpson fasteners by the time I got to that row, used decking screws to supplement. But I'll swap them out before I go any further. Thanks!

The end game is to have a deck around this platform, at the sill plate of the house. The hot tub will be sunken into the deck, leaving a 16" lip, kinda like a bathtub lip.

I sort of thought that with the exposed rim, but since you didn't say, I didn't ask. Should be a great set up.

Just my opinion......

I'm a little leery of the cross bracing. That is the most important part of the deck. I would normally expect to see heavy duty bolts and large washers to keep the bolts from pulling thru the wood.

Thanks for the suggestion PJ! I'll swap out those structural screws for some bolts before I proceed further.

All of the structural bolts have been complimented with lags with washers. I put 3 screws into the ends of each joist, added 2 8" 2x6 cross braces for lateral stability, and lastly, doubled up the end braces also "X bracing".

Thanks for all the support and tips guys, that platform is ridiculously stable now.

Not nitpicking, but if those are Simpson H2.5a ties, you are supposed to fill all 5 nail holes with 8d or equivalent screw. I see only 2 per... maybe cuz you ran out. They also look to have been installed a bit too low.
