One of our first jobs of the season and we hit the weakest soil I've ever worked in. We are installing three steps and a patio. We began the excavation on Wednesday. Wednesday morning my foreman calls and says, "We have a problem." The soil was extremely weak at the normal excavation. I tell him to go to 4', there is enough money in the job. He hits 4' and calls me. "Mike, we're at 4' and no change." I go out to the job and jump into the hole. My feet sunk about three inches. I grabbed a shovel and dug in. I dug full depth of the shovel, at 4', like butter. we wound up going 9' (under the steps.) Anybody else have an overdig problem already this year?
