My "Big Dig" Project

Back in April I get a call from a client about giving him a hand digging out some garage/workshop space under his house and deck. After about a month of hand digging every Saturday morning I finally convinced him, in May, to let me rent a Toro dingo and get the excavation part of the project knocked out all at once.

Pretty fun little project. The client is going to run water and power to the workshop/garage, dig an oil change pit, and pour in a 4-6" concrete slab here in the next few weeks.

At the center of the main cut there it is 8' from floor to the bottom of the floor joists.

Sure seems dangerous to be digging that deep next to those pillars.

Those pillars are set in concrete piers and aren't going anywhere, I made sure to check before I even started working on this project back in April. Those smaller pillars have already been replaced with 6x6's. I just took it slow and stayed focused.

I've had experience running dingo's before so I knew what they could do, although I was surprised it was able to dig through that 3' layer of hard clay

That dangerous that close to the foundation of house. Also I see no shoring of the deck pilar. I just don't see it being much of a work space

Ok just saw you said you replaced them but did you run them down to the current depth of your cut. And what is the customer going to use the oil change pit for I don't see a car fitting under there.

Yes he did run them down a little past the level of the floor. He is going to line the perimeter with CMU with rebar for support (he has this whole project planned out).

Believe it or not a car will in fact fit down there. When he told me of his plans for the pit I said the exact same thing. He bet me $50 his Trail Blazer would fit, I took him up on it thinking I was right. Ten minutes later I was out $50. The main cut is a little bigger than a standard parking spot.

Like I said he did all of the leg work and had the ramp and some of main cut started (by hand) almost a year before he called me in.

Alright let me nip this one in the bud before it spirials into something its not.
And I'm not singling you out just making sure my bases are covered.

The footings for the houses in our neighborhood (the guy lives just down the street) go down another 18" from what you see in the photos.

The client is going to reinforce the perimeter with CMU which will be poured full of concrete with re-bar and tied into the foundation. Or he is going to form the walls up and tie the poured walls to the foundation. I don't know which one. I'm just going by what i was told by my client.

I was not involved with the planning of this project nor do I know all the technical details as to what he has planned. I was brought in a year into his project as a laborer and equipment operator for the excavation part of this project.


These pics were taken towards the end of the second day we had the Dingo so at that point we were just wrapping up the digging. The project is no where close to being done when these pictures were taken. I haven't been back to it since so I don't know how far he has gotten on it.

the soil is not there when the foundation is poured why does it need to be there after. If you start digging below the foundation I could see that being a problem.

No way in hell would I be doing that much exposing of the foundations, I would only do 1/3 and start under pinning.
Break out the level and string line and start checking the roof!

Whats the big deal? They just look like deck pillars. and the wall of the house is well supported by stable well compacted dry soil. Not exactly by the book, but if you get concrete in there quick it will be fine. Worst case you may have to shim the deck after.
