New construction, well about a year old but still new. Hillside construction. So half the crawl space is a true crawl space, hand and knees. The other half is cut into the hillside, about 8 feet lower.
This is the only beam, in the middle of the house running from one end to the other. A total of 9 posts, 5 on the poured concrete in the dug out areas and 4 placed in between those in the rounds.
The cut is about 7-8 feet high and along the full length of the beam, about a foot away from the edge of the poured rounds.
Holy crap where was the AHJ? I suppose that bodes well for the future of home inspections.
Where the slope is steeper than one unit vertical in one unit horizontal the required set back shall be measured on an imaginary plane 45 degrees to the horizontal, projected upward from the toe of the slope. now in english if the cut is 7’ the set back would need to be 9.89’
Im am just finishing up a root cellar…I only dug about 4 feet deep and it was engineered…and yes; rule of thumb is a 1:1 ratio or 45 degrees as previously mentioned…again that also have to do with the compaction rating of the soil.
Update on this item. Talked to the AHJ who looked up some information on this property. Over a year old, does not have CO yet. According to the AHJ, the builder states he has documentation with engineers stamp for the current configuration. AHJ further states that until they get that documentation and perform their final inspection, nothing will be signed off. If the documentation is not forthcoming or does not meet standards, a retaining wall will be required.
Should be interesting paperwork from the engineer. Can’t wait to see it.
great post. while the loading on that footing is probably pretty insignificant it will be interesting if the builder can find an engineer with big enough b_ _ ls to put his license on the line for that configuration. if the AHJ had picked this up they would have already had a letter on file from when they performed the footing inspection. good catch and good service to your client
