How to pour concrete......correctly?

[javadog]

The way that those posts are set into the ground, don't expect them to last all that long. You can't have (even treated) lumber contacting soil.

It's also going to be a ***** to grade the area under the deck. He should've graded the area before he started, or at the very worst, after he set the posts but before he put the deck surface down.

I'm not trying to be the bearer of bad news but this guy did a bunch of things wrong.

I'm guessing that geometry was not his forte...

Unfortunately this is totally worthless and it will cost to remove.

Is the top elevation correct?
Will the rest of the slab be hidden from sight?

you gonna start running straight line on a photo?

Agree with Javedog, those post are way too low. Get em' off the ground or else, you will be doing it again in a few years. As for the concrete pad? I wouldn't have done it that way . It needed to be dug out and at the very least, remove the grass. But for your purpose, it will be there for a few years before it starts to creep away. I hope you didn't paid him lot-o-money for the work

Ummm, is this permitted/inspected? Architect plan? I'm less concerned with grade of posts and pad (really no weight on it but the steps)....I'm more concerned bearing point load of roof (corner post) is not over a footing. Can you get a pic of joist/girders?

JJ - Sometimes cannot do that with pics, curve of optics.

Jay, put a level on the pad. Should be some pitch to drain, not much.... maybe 1/4" per foot.

Edit, nevermind, Canada frost... that pad will be a problem.

Looks to me the bottom form boards gave way on that pad.

Regarding the posts.....from what I understand when using concrete to set a post.....the concrete footing should come up a bit higher than the grade...thus preventing any water from pooling around the posts.

I'm no builder so just my ramblings......

So did I find out by Googling it following look 171 post.

But to BS my way out, I'll bet that on an 8' level the bubble will not be in center line

Learn something every day but I wish it was a working day so I could have gone home...

That roof corner post was the first thing that caught my eye too and I'm a P.Eng licenced to practice in Alberta.

Now that you guys mentioned the load from the roof, I had to look at the pic again. I am wondering if that will be a enclosed living area or a screen in porch? No way they would allow that to be a living space around here.

As others have mentioned call your local building inspector about those support posts or check your blueprints. They should show the elevation above grade the supports should be. As this addition is attached to the house I'm assuming you had blueprints drawn up by a architect?

If left as they are they will rot and that section of house will sag down the road.

I'm in the process of lifting my neibours center beam in her house 5" because someone thought would be a good idea to encase the bottom of 10 X 10's uprights in concrete. The bottom edge rotted. It took several years for this to happen but left without correcting the main beam (and first floor) will fall into the basement.

Oh.....and that pad is wrong.

Forget that little pad.

JJ 911SC, you need to:
1). Remove all the interfering decking from that entire corner,
2). Shore up and brace load.
3). Dig a hole 48"+deep which is compacted/sand/etc/idontknow You are snowbelt also.
4). Put post under post all the way up.
5). Create a platform to support the entire corner of the house.

Scary stuff there man in my eyes.
but I'm not an expert.
There is no foundation for that roof extension which would pull everything else along with it.

Had some time to think about the pad and it "could" be on a pile but as there is no dirt around it I find it quite unlikely. Based on the amount of dirt around the house supports they didn't go into the ground very deep. But they could have cleaned up the considerable amount of mud that would have come out of each hole they would have drilled for each post. I don't see any bobcat tracks used to haul the mud away but they could have used a wheelbarrow. That's a lot of mud from 12-14 holes. Diameter squared X .7854 X length (in feet) or about 1.7 sq yds at 6 feet deep. But maybe there they aren't required to go that deep.
