I do not know what your frost depth is, but you might be able to get away with placing insulation below the stair and as an apron at the top of the stair. NAHB and HUD have published ...

Hi David, Former NYC foundation engineer here. Usually in New York City, Site Class F is triggered for liquefaction susceptibility. The code has a conservative and overly simplified screening process that is sometimes misapplied leading to false positives. Given what I know about Manhattan subsurface ...

I am a structural engineer, but I started my career as a 'foundation engineer' and had the opportunity to see the exploration, design and construction sides of foundation problems. As such, I have been both a user and generator of geotechnical reports and have seen the collaboration go well or not exist. ...

I assume that you mean the term in some form of the Tergaghi bearing capacity equation that accounts for the overburden or backfill above the footing bearing surface. If you are using some other method, the surcharge term may not apply. As mentioned by others, considering the depth of the foundation ...

Jordan, The allowable lateral bearing capacity and the passive earth pressure are very different things. The passive pressure is the maximum pressure that can be developed on an earth-retaining structure before failing by shearing a displacing a wedge of soil. It can be adapted to a pile but the theories ...
