wow.

My engineering background saying ugh, however I am not a civ engineer. I assume they installed brackets anchored at the bottom of precast stairs attached to the house. The trouble with the current setup is pillars appear too close to the house. They should be more towards the front. I do not like the leveling cuts as they created weak spots on both sides of the cuts. I would expect no cuts and steal shims vs whatever c.p their stuck under. Most likely the pillars were too high.

I doubt with precast staircase that the middle has to be filled in. I would contact the manufacture of this precast and email them a pictures to see if this is acceptable practices.

Me thinks it will crack on builder created weakspots.

Without an engineering background, I say ugh.

They didn't do any site prep before they began the process, and it seems clear to me that they're not supported completely along the bottom. No, no, no. These steps have a short lifetime ahead of them, and then you're going to be right back where you started.

Where is the required flashing behind the step units? Tyvek is not flashing. Major code violation already...And by the way: UGH!

My concerns were with the flashing also...even with the siding installed there is a good chance water will enter where the top step meets your home and eventually rot the OSB. With not filling the void under the steps at all there is going to be a low spot there and unless your final grade is built up higher water will collect under your steps.

Water under the steps = rodents and bugs too. Yuck.

The whole thing needs to be redone. Probably the part with the chunk removed from it needs to be re-ordered.

They should have graded for this and put some kind of gravel or something to support where the pilings aren't.

Nightmare. Honestly.

I think your best bet is to forward these pictures to the manufacturer or inspector and have them help you with getting it redone.

Thanks for the replies, please keep them coming.

Great point about the flashing on the house. That hadn't crossed my mind.

I spoke with the site manager yesterday. He didn't say much but did take some pictures and is going to look into it.

UPDATE: Apparently the owner of the of the company that did the supply and install (Barkman Concrete) inspected the installation and claims this is a standard installation with no issues. I'm following up with the owner of my general contractor.

I does not appear that they graded the fill away from the house or flat even. Water will collect under there.

I missed this Manitoba mess.

I've always done front porches on new builds as part of the foundation.

For instance:

Rebar in porch footing.

Pouring footing.

Pouring into rebar reinforced foundation forms.

Finished and ready to be stripped.

Adding rebar and heating to the porch slab.
