Field mess - Deviation of the DWG

Field mess - Deviation of the DWG

Field mess - Deviation of the DWG

(OP)
Dear colleagues the contractor sent me pics of the top the drilled pier that the hooks were supposed to be orienting out side of core of drill pier but the placed them as in the attached pic.
The longitudenal bars are #10. They said the hook were falling out of the foot print of drilled pier if the were orienting them as in drawing facing outside.
Is that causing problem?
What shall I do? Please advise.

Thank you

RE: Field mess - Deviation of the DWG

I doubt that the hook orientation makes much difference, but am curious as to what your photo is showing. What goes on the piers? What is the concrete slab? Why the circular hole in the slab?

RE: Field mess - Deviation of the DWG

I'm confused. What is that actual problem? I'm not following your description.

hokie66 (Structural, thak you for response.
The slab is an unreinforced slab-on-grade.
The hole in the slab is after a drilled pier (deep foundation) is poured.
The rebars that are sticking out and you see in the photo are 6 #10 longitudenal deformed rebars that are 180 degree at the end as is in the photo.
My question was, the contractor has rotated these bars 90 degree from original orientation and as you see the hook now is placed on the cirfumference of the cross section.
I have not seen this orientation of hooks in past so was wondering if it causes any problem.
A fabric structure with arched trusses will sit on top of these piers.

Ron,

My apology for not being clear, I was so caught up that just wanted to put words quickly and have opinions.
If my explanation to hokie66 is still not explaining my question please let me know and I will try to explain it in a different way.

Thanks

RE: Field mess - Deviation of the DWG

What loads are you transferring (any tension or moment)? I don't see that the direction of the hook matters in this case.

RE: Field mess - Deviation of the DWG

Consider what you really need the hooks for. Will they still develop in tension? Do they need to, or can it be a compression splice

Not to be critical, but I don't see any other way to install these. The detail should address this.

dcarr82775 (Structural), thank you for your response.
The loads are as following:

Superstructure load: 9.15 Kips Downward

Uplift Superstructure: 11.62 Kips Upward

Superstructure Horizontal: 6.61 Kips Horizontal

Since the superstructure is pin conncted, therefore no moments.
Does above information change your statement on the direction of hook?

I am wondering what possible effects will have the change of hook direction?

Thanks

RE: Field mess - Deviation of the DWG

12k up and 9k down?

You're fine as is. I'm surprised you have #10s in there.

RE: Field mess - Deviation of the DWG

perhaps upload your original drawing, and whats connected on top, and we can give a better opinion, but as Manstrom said, its a moot point with those loads, your fine.

RE: Field mess - Deviation of the DWG

This is not a case where the term "field mess" applies. The term field mess would be for a case where the contractor omitted the hooks or the bars were terminated inches from the top of the pile. All's well grasshopper. Time to move on to something more critical.

RE: Field mess - Deviation of the DWG

12kips. Keep calm and move along. Nothing to worry about here.

RE: Field mess - Deviation of the DWG

I agree that the given loads are not great, but would still like to see some details of the intended connection of the columns to the piers.

There is exposed soil between the top of the piers and the bottom of the slab, and without care, this will run onto the piers.

Is the structure which supports the fabric moment resisting, or is it guyed?

RE: Field mess - Deviation of the DWG

(OP)
hokie66 (Structural, thank you for your comment. To answer to your question on the soil, the soil is because the drilled pier diameter is smaller (different) than the cap (which is not pour and you just see the bars there).

Any advice on this matter, any comments that I can relay to site for bettering the construction?

The structure that sits on top of caps (top of driled piers) is pin connted to drilled piers. It is not guyed structure. but in the spaces between trusses will be winched to the floor.

Hope I answered your question. Please give your opinion on the soil you mentioned.
