Title: Second story deck
Post by: KSUTOMMY on October 03, 2010, 09:17:25 PM
Have any of you all built one? My house is built on a hill on a gi-nourmous amount of concret/block foundation stuff. We have a covered concrete patio which is one story off the ground and has wood "deck-like" stairs that wrap around and down to the yard. We have an area ajacent to the patio where I would like to buid a deck and incorporate the stairs, however - that is where the worrying begins. I fancy myself a handy guy who can build just about anything, BUT - I have a family who will be hanging out on the deck and perhaps the last thing I would like if for the deck to fall down and have some kind of catostrophic injury. I have built 2 decks previously and if it were between 2' and 6' off the ground, I wouldnt be posting this - but I would like a little guidance from any of you all out there who might have done this at your house maybe with your pops or something.

I have experience with 2nd decking at another person's house.  Seriously though, I have actually been on a 2nd story deck that collapsed with a bunch of people on it.  Luckily, they were all adults and no one was seriously injured.  Lotta codes to worry about and permits to pull, etc.  Just hire it out, a deck is not very expensive and you will basically recoup the money in increased value of the house.  If you have to, take out a small home equity loans or something.

Excellent point (also, I love the idea of deducting the interest from the home equity loan). NOW, the research will begin with finding someone qualified enough to do the work. There are lots of Mexican/Hispanic/Latino crews here in San Antonio - but by the transient nature of these crews, I am a little gun shy of grabbing one to do the job and being somewhat new here, Im not exactly sure of who to go though. Ho hum.

Just build another deck 2' below the top deck so that if it falls if only falls 2' to the second deck.

Just put some posts under it and you should be OK, bro.

Seriously, building one on the second floor is not much diff than a first floor, just longer posts.  The real diff is the posts will be much longer and you will have to account for horizontal deflection.  You overcome deflection by installing intermediate support between posts.  Tell your lumber yard sales guy what you plan on doing, and how far off the ground you will be.  They should be able to let you know how much post-to-post support you need and how often.  It is a very easy/quick equation.

Once you account for the horizontal deflection, other than working that high off the ground, it is pretty much the same as a first floor job.

Also, if you are noticed, the city will require a permit, which will require stamped drawings for permit review.  Find a good lumber yard to buy your wood from and they should be able to draw it up for you with calculations and all for a very small amt.  Sometimes for nothing, if you are buying enough wood.

Believe me, if it's ground level-  Buy some beer and have your buddies help do it.  It'll take one day of decent work with 4 dudes.  2nd story decks are a whole different matter.  It's not worth your time, unless one of your buddies really knows what he's doing and will donate his expertise.  You have to brace them to the house differently, the footings are different, it's just a bunch more work/planning and the stakes are much higher if you eff it up.

If ftgs are your concern, dig a slightly bigger hole.

I have built plenty of these.  the main diff is working over your head while on a ladder rather than on the ground.  prepare to have some tired arms.

Most of this is untrue.  The only difference between a ground level deck and a second story is how long your posts are.  Otherwise you build it exactly the same.  Everyone stop being such a FP, TC etc.  And by everyone, I mean JT.   :facepalm:

Just built a deck this summer.  Found a pre-designed plan ($30) on this site that was exactly what I wanted, or you can have them make you a custom plan.  I emailed them several times with questions during the process and always got a quick response.

If I was building a deck for someone else I would have no problems.  I'd do whatever you hardasses do while drinking some cold beers and grab assing with my bros.  But, if it was my own house/deck we were talking about, I'm calling in the pros.  Just a fwiw.

I helped my dad build a 2nd story 2 tiered deck at my parents house this spring.  Not very hard.  Was time consuming, though.  We were pak'd most of the time and it still looks fantastic.

solution if you're really worried about it collapsing would be to load up a bunch of your spare pillows underneath it.  if it falls then you will just land on a pillow.  no harm no foul.

just dig a big ditch underneath and fill it with water. keep you spare pillows inside for guests. problem solved.

Kinda irresponsible if you intend to have guests over that don't know how to swim.  That is, unless you were working under the assumption that the pillows were also personal flotation devices.  If so, my bad.

you could fill the moat under the deck with high strength balloons.  if the deck falls, it will fall onto the high strength balloons making for a soft landing for everyone involved.  no harm no foul, what's the crime?

Obvious solution is to tie a zip line between your roof and the nearest telephone pole and connect it to your deck.  If the deck fails, you get a kick ass zip ride through your back yard.

i was actually planning on making people who go out onto the deck put on life jackets. your idea works too...i guess.

u should prolly go w/ the water filled ditch. go borrow a few of ur neighbors tires and tape them to the underside of the deck. when the deck collapses, which it more than likely will, u have a houseboat. people love boats.

i will add that this deck seems dumb and dangerous, but if you are serious about building it then you will need a lot of structural support. kougar has a pole of some sort in his basment that he needs to get rid of and he might be willing to let you use it for this project. i'd check w/ him.

As someone with a construction science degree (like Casey) and who has built a dozen decks, this isn't an impossible feat for a skilled homeowner, but based upon your questions and lack of confidence, I would suggest you have it built by a professional.

The contractor needs to verify the structure of your home to determine the best method for attachment, needs to check the span tables for the lumber to ensure it is adequate, and needs to either have a good understanding of the footings required or know someone who does and get their direction.   Improper bearing soil or undersized footings could cause the deck to sink or worse
collapse.   While this is a possibility of any deck built by a novice, most of the time a 2 foot collapse isn't going to kill someone.

Many people THINK they know how to build a deck, but even after watching a recent DIY show where supposed deck experts competed against one another, 2 out of 3 improperly built the structure.

If it collapses just start cracking up like it was a practical joke and yell "gotcha!" at everyone as they climb out from under the rubble.  Everyone will probably start laughing and high fiving you and they'll be so happy from laughing that they'll probably help you rebuild the deck.

As someone with an Econ degree from Kansas State I can tell you that the opportunity cost of not making the deck out of boats which float in a mote is high, very high.

Dumb idea.  Decks, in theory, are basically just boats that never go into the water.  So, in theory, putting a regular deck into water automatically makes it a boat.  No need to make it "more" of a boat by building it from water boats.

you can shove your undersized footings right up your ass, pancho.  this deck is going to have proper fittings and i don't care what anybody says about it.  the footings will be proper.

As a Structural Engineer I recommend you find a contractor who will use a structural engineer to stamp the drawings. Contractor will most likely design the thing and the SE will just review and stamp. Probably will cost a couple hundred dollars, but will be worth it.

LOL.

Seriously though, you are going to need to sacrafice a chicken on that deck minutes after completion or you WILL be at risk of malicious spiritual infestation.  You can do it yourself if you want, but giving $80 to a priestess is the only safe bet here, in my experience.

No rely find an engineer to stamp the drawings, even if it's a crappy engineer. That way if it falls down and disfigures/kills people/animals you sue the engineer.
