Sono tube should not be below grade. Doing so eliminates the friction between the Earth and the concrete. Not that it's a concern in this case but what about attracting termites?
Clay sewer pipe is not allowed under a building. This addition is at the front of the house and naturally, the sewer is in the street. The house was built sixty years ago so the odds are great that the building sewer is clay. I wrote a correction at the foundation inspection asking them to find and identify the sewer pipe. They were also too shallow by ten inches...the footings that is.
This should be caught at the plan review stage. It seldom is. I have alerted every new plan checker that comes to my office. I have suggested that the plan review correction sheet mention this....that has not happened.
Termites love form boards.
The dobies are on the wrong bar. None of the steel is doweled. There was an inspection report from the geo. engineer. I said that 12" of soil was removed, the ground was scarified, the soil was replaced and compacted. In the box for the density, it said no tests done. I called the geo engineer to find out why there was no density test and he said, "We're not done yet and will test on Monday". I told him that there are many cracks in the soil and it doesn't appear to have been removed and replaced. He said that he would go there himself. All of that for a garage slab.
These rebar caps are not OSHA approved.
There is 60' of trench 4'x2'. They didn't ask anybody about cutting the sidewalk and placing their footing on public property.
When an engineer designs a deck!
The slab is for cell site equipment cabinets. They must have a need to burn through money.
How thick should the slab be?
Finding a conflict with the electrical service is not uncommon. The gas meter is rare. The contractor wanted me to approve the form-work so that he could place the concrete. He assured me that he would deal with the gas pipes later.
There is an engineered plan. The shoring is not part of the engineered plan. The idea is too remove the shoring before placing concrete. The correction stated provide sacrificial jacks.
The HD anchor is held in place so that it will reach past the raised floor framing.
Those rebar caps are OSHA approved.
This part of the job is a slab replacement because the Earth shifted and broke the original slab. Inspection was requested for Thursday. The contractor called me at 8:50 am asking for a time when I will show up. I had a full day and told him that I would be there between 11:00 and 2:30. The office called me twice because the contractor called the office wondering where I was. He called at 11:30 and 12:45. I arrived at 1:44 and nobody was there. It is a large apt. complex and I didn't know where the work was located. The apt. manager was not on site....so I left. When I returned to the office an inspector told me that the contractor just called to cancel the inspection.
The next day a woman from the contractors office called and wanted to know why I stood them up yesterday. She made it clear that this was unacceptable and they are pouring concrete on Saturday so I must do the inspection today (Friday). No time was requested because the apt manager will be there with the plans, jobcard and soils tech. report.
SECTION R408 UNDER-FLOOR SPACE
R408.1 Ventilation. The under-floor space between the bottom of the floor joists and the earth under any building.....
R408.5 Removal of debris. The under-floor grade shall be cleaned of all vegetation and organic material. All wood forms used for placing concrete shall be removed before a building is occupied or used for any purpose. All construction materials shall be removed before a building is occupied or used for any purpose.
That's the code and I can only apply the code.
All of the dobies are on the wrong bar, all of the re-bar caps are illegal, the steel is falling over without having concrete push it around.
When a trench is next to a building and deeper than the bottom of the footing the replaced soil shall be compacted to 90%. The only way to verify the 90% is with a compaction report. Or fill the trench with slurry.
Nobody asked any questions about the sewer until after the work is formed up. Ya I know, but well.... that's the way we do it around here.
These have an edge distance requirement and that's not it.
This was an open patio cover. It was enclosed without permit years ago. Now there is an effort to morph it into a legal addition.
The hole started to fill with water so they cut off this much steel. And everybody always says that inspecting commercial work is soooo much easier than residential.
They still had to get this in the hole. If you see these, remember that the top has more threads showing than the bottom. It has been done wrong in the past.
Here's the engineer's detail. Note that the wood post is shown embedded in the concrete.
There's quite a bit of work here. It looks pretty good. It's too damned bad that it has to come out. You see, they didn't see the detail that shows the footing 24" into undisturbed soul. So they are 16' to 18" deep.
I have encountered this hundreds of times. Yes I said hundreds. It is because the detail is small and the writing is tiny and the info is nowhere else on the plans. Hell, sometimes I have to search for it. I have asked that there be a big warning on the foundation page. Apparently that would be too much trouble, but doing all of this work over is no big deal.
