Yes, I agree, much unhappiness will ensure, and much more money on his part.

Does it not have to be inspected by the building dept. before footings are done?

Why does this contractor need to know where my footings are?


They have stopped digging, and I have noticed today that the contractor was there with some guy with the house plans in front of them. The contractor asked me if my basement floor was all one level, which it is.

I am wondering as to what affect does this have on my foundation since they have stopped digging? I can see some ground water. They have dug approx. 2 1/2 feet away from my foundation wall.

Are they not disturbing the soil around my foundation as it is empty now?

Thank you.

I will be contacting the contractor tonight regarding my concerns, and possibly calling the city inspector.

How much lower than your foundation wall, or footing even, are they? I wouldn't go assuming the worst yet based on the facts that you mentioned.

If you can post a pic that might help too
So all of the dirt between your house & where they are digging is gone ?

Everything looks fine to me, it looks like good, stable soil. It appears the excavator is a good operator as well. From these pics, I'd say you can expect a drier basement in the future. Maybe you'll owe these guys a beer by the time they're done...........

Not to upset you. What are the two pieces of pipe in the picture, pink looking, one is under water, the other sticking out of the dirt, like drain tile..........

Be safe, Gary

The only concern I have is that the front part of the house is only 4.5 inches away from property line and I am certain that he will be digging lower than my footings.

Here is a pic of the front part of house.

Speaking seriously for a minute, the Angle of Repose is a highly critical consideration in excavation here in Florida where we have mostly sand.
Many times we are required to drive deep "sheet pilings" along side an excavation such as they have dug next to your house to contain and restrict any shifting of the supporting soil beneath your footings....... or from the edge of a steeply sloping lawn or cliff-like topography..... and especially from the edge of a waterfront property line.

In most cases the angle here is 45 degrees. (Not to worry. It is obviously MUCH less where you are.)

In other words, if the bottom of your footing is four feet down, we cannot disturb the soil within four feet of your house's footing edge without initiating protective measures. The stipulations also begin to exacerbate in restrictive encroachment distances with deepening excavation. It is an engineering thing, but I think the A of R actually reverses as you pass the bottom of an adjacent footing, and of course, progressively widens as the digging depths increase. I'm not well educated in these things, so I do what the guys who are say I am supposed to do.

Thus.......... the sheet pilings are used to segregate the two properties till the digging can be effectively replaced with fully supporting (compacted) soils.

Gary, I think that they are merely remnants of the draintile from the existing neighboring property. If YM has draintile that is running across the neighbors property, that's her problem to deal with IMO, not the home builders, or especially the excavaors.

They are remnants from the demolished house.

Willie T, they have not installed anything. In fact they have not completely excavated. The blocks that you see are still from the old foundations of the previous home.

Well, as I said, we live on mostly all sand down here. It is one of the most solid foundation soils possible.... BUT it can easily migrate if not contained somehow.

Where you are, you likely don't have that problem. From the looks of it, they could probably go another foot closer to your house with no problems.

Thanks Willie T for your help.

We are speaking with the contractor tomorrow regarding this issue.

He said that he is taking all the necessary precautions regarding my footings and foundations. He stated that he is doing block foundation and he will be back filling by hand.

I think i may contact the building inspector for a second opinion on it.

Idealy, they should be running a compactor across the backfilling at every 8". But no more than at layers of 12" between compaction passes. A really conscious contractor will just have a man in the ditch the whole time running the compactor. Might be something you want to keep an eye on.

Sounds like you have a good man to work with there, but it never hurts to keep an eye on things.
