Thank you all. The existing soil is silty sand in few locations and silty clay in couple locations. Much of the existing soil is being replaced. However the 60 day period was recommended without any basis. There was no calc to support that. So that's why the contractor would like to reduce the...
Hi,
We have a site where the existing material is organic, silty and which is replaced with compacted structural fill. There is an additional 10 ft of fill as well. Do we need to wait 2 months to build on it. Or can we monitor settlement daily and begin construction after 30 days.
Thank you all for your responses. The passive pressure for 3 ft below ground is ignored per Pennsylvania code. This is in PA. The pile is encased in concrete making a total pile length of 43.5 ft. Their slope stability analysis have a safety factor of 1.6. I will look into tie back design. Thank...
Thanks for the responses. The pile spacing is 6'-0". Fill is actually original ground. The proposed plan is to excavate 13' and construct soldier pile wall. In the borings they have sand for top 13' and sand and gravel for bottom layer. No rock is encountered. I am not convinced with the...
We are proposing a soldier pile wall with drilled caisson for a slope repair project. The height of the wall is 13'. The pile embedment is 30.5' in soil. No ground water table encountered.
The soil parameters for the fill: phi- 30, unit weight - 120 pcf
The soil properties below subgrade: phi-...
Hello,
I am designing a temporary shoring for a retaining wall along the approaches of a bridge. Temporary sheeting with struts is provided out side the retaining wall.2 struts are provided at 1ft and 5ft below ground elevation. The contractor does not support sheeting on the embankment side...
