Soil Engineering Analysis and Footing Recommendations

in a minute you're gonna meet the soil engineer but here's a little bit of history on him he's over 74 years old and throughout his career he's tested over 39,000 different Lots he's had two major knee replacements so he's not very mobile so I'm gonna dig this trench keeping that in mind now we've got to get down to the bottom safely with a person that may not be able to get around all that well [Music] so he wants me to lower him into the test pit but I've watched him Walker on this site I'm not going to let him do that we're going to talk to him in a minute and I'm going to tell you that these are the kinds of guys you can learn so much from so let's see what he has to say so before Brian became a soil engineer he was an operator I had one of these I had a track hoe and I had to drag lines American crane six before the stick maybe put a stick for gigging pond it's a but the thing is these were those were friction rigs so I started getting a little corporate ah so what are we let the Sun Shine on it see oh yeah it's a high silt content okay it's like sucking on a straw all right it's this is loaded with moisture yeah okay it's silty it's not necessarily clay okay so it's more silt when you dig this job you're gonna have to go down to be safe to be safe I'd say you're gonna have to go down about all for the half great local oh great the law exists where they're standing right there okay that's the bottom of your building area footings down it if if you go deeper I've got a house typical house pad you'll be about 20 inches wide with your footing with the footage so you spread footings 20 inches wide 20 inches wide typical okay but for for this I would say you go down two feet come back one foot come back up one foot compact that and place your footings at about 24 inches wide okay okay you're spreading them out just a little bit you put them on just just touch your fill not very much at all okay so you want us to over dig then to bring spill soil back in back in yes okay and also safest way right here now that's your footing elevation then you come up I would say come up to probably raise pockets okay and that would be right where his fist is right there right and that would be your elevation for this the garage and the law house more we'll be at the same elevation so
