A certain 1957 Buick comes to mind.

Denis and Milt would have had fun with this project!

And that's no ordinary Buick! ;)

Well, /Wayne let the cat out of the bag. Yes, I'm at Pelican covering for a vacationing sales rep and hoping to go full time at some point. A lot to learn and a very tightly run ship!

Wayne and I did discuss this over several emails and I think I brought up the idea of using the concrete piers for anchor points of the uprights. Wayne says they act like 911 rocker arm swivel feet adjusters. You can take a man out of a Porsche, but apparently you can't take the Porsche out of a man. :D

Good job, Wayne. It makes me sore just to look at it. I'll keep my desk job, if you don't mind. :)

I don't get? I nice pool boarded up like that. What a shame.

I knew how to swim at age 3,,,,But to each his own, IMHO swimming is the only "sport" all should know. A "sport" that can save your life...

Now I understand the phrase "disposable income" a bit better.

maybe go back in the thread a bit. :)

I have a pool, and the following are some things I was told:

1. A 20x40 pool would require $8,000.00 to replaster, new bullose deck, and new tile.
2. To fill it with dirt, it would cost over $12,000.00 (inspection, permit, blah, blah, blah.

So I went with pool reconditioning.

3. I was told that if you keep the pool empty, it would lift somewhat as it needs the weight to keep it down.
4. The plaster would get destroyed if you left it empty.


Wayne,

Good luck!

That was a very very nice pool, Just dont let the kids in the back yard or tech them how to swim young or that pool net looks good too. Anyway building a deck over the pool not my thing, but hell at least your doing a good job at it

Curious what the weight of the completed deck is percentage-wise to the water that was in it. Certainly a fraction but how much?

While the approach is not what I would do, Wayne is certainly thorough and appears to have thought everything out! I would assume an inspection is part of the thoroughness.

This project is an amazing amount of work for one human!

The kids will probably have more fun in that big, inflatable water wonderland than a regular pool anyways . . .

Best to you and your family, Wayne. :)

Wayne and I discussed this. Now I see that the plaster is not that good now, so it's not like a brand new pool. I had a old dog of a pool and acid washed it and then finally painted it, Looked great for some time.

AFA lifting, he has had professional advice on the surrounding soils condition and he has a good situation AFA peculation, etc. This should work out.. As last course remedy for a pool that wants to float out of the ground, coarse gravel and a sump pump could stabilize an empty pool that is getting nervous.

One website I went on to read had this theory that pools didn't move but saturated soils around it would. It wasn't quite like the pool would float on the ocean, so how would it float in it's own mini lake?

Hey, just one person's writings.

I'm a pool owner, and I would love to fill mine in!

Wayne, I have 4 sons, and I bought a fence for my pool. BUT I Concour with your idea. with a special child family dynamics need to be looked at.

my concern is that the weight of the stucture is on to small of a footprint and might bust past the plaster.

I would increase the footprint two ways first MORE feet secondly 3/4 marine grade plywood under the concrette feet as lodspreaders say around 24"x24"

Like a previous poster said tthe walls of the pool will help prent it from sway. but I would still bring in more triangles and look at shearwalling a few spots.

I would try to not place the toppieces in too tight to allow it to breath.

Good Job so far!

Correct-o-mundo. You've done your homework. :) I think I mentioned that somewhere earlier.

"Exterior grade" or "treated" lumber is reasonably safe now. I'd still wear some good gloves while handling the stuff, but you could probably get more/better information on that from either the manufacturers or guys that work in the construction biz actually installing those materials (means & methods stuff I typically don't get into).

You can level the bottom of the pool by filling with layer(s) of sand, wetting & compacting. Then those piers will have a chance at being level.

Additionally, I would tie the joists to the sides of the pool somehow, to keep them from twisting/folding in the event of a seismic event or over-load. Did/will you install blocking between the joists? Those long boards will twist and I doubt the attached decking will prevent that. In lieu of blocking, use some Simpson x-braces or seismic strapping across the top of the joists in an "X" pattern.

Well...hopefully someone with more experience than I will chime in, but I believe blocking/bracing is important in this situation. You are basically building a raised deck.

Here is a loft I built w/2x12's 12" o.c., rim joist, heavy joist hangers & topped with 5/8" ply, screwed & glued. I still used blocking (you can see it down the middle of the pic). Span is 19'6"...:

From the Simpson catalog:

Notice the disclaimer "Hurricane Ties do not replace solid blocking"...

Personally, would have enclosed the pool with a building with a retractable roof.... this way the doors could be locked to keep the kiddos out.... and the pool could still be of use... but to each his own.....

IIRC there were some pretty ugly lawsuits over chromium copper arsenate (CCA) impregnated exterior wood a few years ago that had been used in exterior applications like decks and playground fences. Splinters and incidental contact gave a few kids serious poisoning, hence the uproar over the stuff and the changeover to the copper "quat" impregnated woods.

There are still a number of CCA decks, wood foundations, sill plates, and who-knows-what-else out there. Generally speaking they're not a problem unless you get a splinter from the wood or handle the wood as it is leeching material out. You can also seal it (of course if you're going through the time/effort/expense to seal it, it sort of defeats the rationale for exterior grade PT lumber in the first place, but that's another discussion. . .)

Generally speaking the copper quat ACQ stuff is supposed to be reasonably safe although I still wouldn't go making picnic tables or park benches out of it or whatever.

There are also some issues regarding building material recycling with CCA-impregnated lumber. . . A G.C. would probably know more about that than me though.

It's irrelevant! He's using redwood as a deck surface! No-one will ever be in contact with the treated wood!

http://forum.motorcycle-usa.com/atta.../deadhorse.gif

Not directly, however rain water can potentially wash the leeched out chemicals into the bottom of the pool, where they'll be pumped to who-knows-where. Redwood is a good finish material - termite resistant and pretty durable. There's also a bazillion different synthetic finishes that can lay on top if one is concerned about nail heads or screw heads eventually starting to back out/stick up, etc.

Overall I really like Wayne's concept. It's a neat idea and not something one sees every day, but as with such things there are issues that have to be addressed also that aren't the "everyday" variety.

The discussion isn't about other projects. We're specifically discussing Wayne's project at hand. Never did see him ask for advice on treated lumber.

The "builder"? Have you even read the post? :rolleyes: squared

DOH! I mean, er, um, predators.

I like the pudding idea. But can you imagine drowning in 10' of pudding?

I'm sure Wayne is aware of ACQ's ability to eat common fasteners, he seems to have done his homework. The average homeowner, however........ I predict the demise of ACQ is the day that elevated decks begin falling off of homes because the galvanized lags were eaten by the treatment chemicals. Oh well, it's more prone to twisting than CCA anyway. 60% of treated lumber at the average lumberyard is so twisted it can't be used.

Rubbed me the wrong way? ----> :rolleyes:

"Brown-nosing"?!? When you give (frequently inadequate) advice, it's considered "assisting". When I give concise & accurate advice, it's "brown-nosing"? Whatever...

Go herd some Goats or whatever you mountain-people do.

For god's sake, it is simply a wood deck covering a pool. If it feels flimsy when finished, add a few braces..... My ONLY concerns, if this were my project, would be for avoiding damage to that beautiful pool.

Sheesh...944 owners. I just never got along with 'em. SmileWavy

However...it's an 8' drop. Not like he's building a deck on the ground. One failure and the collapse will be spectacular.

I personally would not be scared in the least to walk on that finished structure. It could be built 1/2 as strong and I still would not worry about a sudden major failure/8' drop to my death. I guess we all have different fear and safety levels based on how, when and where we grew up.

I'm referring to an overload situation (backyard party, etc.). The 8' drop might not kill you, but the ton and a half of falling lumber might.

Tim, you need to read more closely. Wayne wants to park his F150 on it.:cool:

Interesting project Wayne, good luck with it.:)

The biggest problem I have with it are the angle of the concrete piers the 4x4 posts are sitting on. They are designed for a plumb, verticle compression load. That angle looks hairy to me.
I know here in NJ there aint a shot in hell of that passing an inspection.

you put 30 folks doing the macarena on that as a dance floor, and you better be damn certian it will hold.

I thought in NJ that entirely depended on how many $100 bills were involved. . . ;)

There is no bribery in this fine usptanding, moral state!! We have the best inspectors money can buy :D

If I were dancing the Macarena in unison with 29 other people on a deck built over a pool and it collapsed into a twisted pile of people and wood I would consider it Divine intervention. I would prefer that a close friend shoot me execution style and then keep what he saw a secret from my other friends.

friends don't let friends dance the Macarena.

You said it better than I ever could, but that was exactly my sentiments when I read that post yesterday. Wayne, could you put some "sensors" in place that would guarantee a collapse under these circumstances :)?

Kids ages 1, 2, and 3? Is there a rut season on the left coast? :D
I'm with the group of teaching kids to swim. My parents raised 3 boys with pools, lakes, rivers all around. A 'right of passage' was to swim across the Allegheny River which I did at 12 years old. My father in a row boat next to me. Talk about a confidence builder for a child.
Good luck with the project. Does look pretty cool.
