Hello all
Mew here a my first time dealing with a compaction test requirement.
First off let me explain that by we are building a metal carport port barn 44x40 on a 4” concrete pad with 12” deep footers.
Also: I am a self contractor property owner with experience in residential building only.
Since the structure was to be built on a slope we hauled in about 40 loads of rock/soil mix and spread it S we went.
Much of it was spread with a tractor loader and some with a large skid steer.
The lower end required about a 16’ depth to near nothing on the upper side.
We had the footers dug and the inspector came and immediately requested a compaction test.
In our area a compaction test is done by an outside Geotechnical company and I pay for it.
Since I have never dealt with this before I was looking for some input about the test and how they could do it in the rock and dirt mix.
From what I have been told they use a rod to press down into the fill then an auger and then some type of cone test where they drop a device onto the fill from a certain height.
Here are my concerns.
The rid and auger is going to be difficult to get through the rock and soil mix.
Is this a good or bad thing so far as the test goes?
If for some reason the test is unfavorable what are my options since I already have the footers dug and everything set up ready to pour?
And as far as compaction what would I use to further compact the fill to possibly get it to the required result.
This has become a sudden nightmare and I just wanted to build a barn to store our truck and farm equipment.
I could have built it without a permit but I was trying to do the right thing.
Any suggestions or thoughts will be welcomed.
Please try and keep it simple and not to technical. I just want to get this all over with and done.
Thanks
