Or, a very short 1 foot toe can overlap on top of the existing driveway which would shorten the driveway to 9 feet wide, and a short 1 foot heel could be deepened into the key. Then hand held rock drills could be used to drill holes for grouted dowels that are embedded into the key/heel. The...
The owner got the prior engineer for the house to write a letter stating the house is founded on bedrock. Bedrock is very shallow and the slope between the house and driveway is cut from leveling the pad for the house and consist of some top soil with limestone chunks.
The wall will be 2 feet...
Thanks for the great insights!
Meet with the city building inspector and the issue is larger than I was aware. (I was called a liar, and demand I tell him my PE number?!?!?) I had not walked around to the back side of the house. Basically a wall is needed around most the house. There are trees...
Thinking further about this, it seems like the edges of the fill pad for the house was just pushed to form its natural angle of repose overlapping the sloping topsoil and vegetation, as the main tree in the way is buried a couple feet.
The city okayed it, now the house is being sold and they...
I made another site visit and attached a better photo. The corner of the house appears to be placed on fill, and the bedrocks location is uncertain.
1. I am in the process of getting the original geotechnical report for the house. The structural details show a waffle slab and a note says that...
Thanks MTNClimber. I will try to get a better picture of the situation this morning. I was going to set back the second wall 6 feet. The local building codes require 1.5H for tiered systems to not be counted as a single wall. Even at that, I am applying the second wall as surcharge felt by the...
I was informed by the general contractor that R-walls taller than 4 feet had to be reinforced concrete to get permitted by the city. I looked up the codes for the city and this is not the case, they just have to be engineered. That was why I was thinking of doing tiered walls.
If one taller...
Thanks for the replies. I wish I would have taken a better picture of the site. There isn't much top soil, the driveway is excavated into the limestone rock, so the lower retaining wall will be sitting on rock.
The leaning trees observation is good insight. The one nearest the bag wall is of...
Attached is a picture showing the site conditions. The bag wall is not acceptable and needs to be replaced. The ground conditions consist of top soil over limestone. There appeared to be some leveling fill, but the corner of the house is resting on limestone rock mass.
My thoughts:
1. Global...
Hello, I have only been working a few years and most my experience is pretty basic. Now, I no longer work for this company, but I have a few remaining questions I never got to ask the boss. Any help on these questions would be great.
1. For piers - the reports say "the bearing values are...
