pop top project
pop top project
(OP)
I have a project of a pop top project of an old brick house w/ basement. The soil report came back and it is only giving me 2000psf soil brg. max. I assume the footing is 16" wide. After I add up the loading I get 2800 psf of pressure. What do I do? What do most people do on pop top projects?






RE: pop top project
You may have a footing much wider than 16" on an old brick house. Even a frame home with brick veneer should have 18" or 20". If is a real brick home, it should be thicker unless the joists are embedded in the brick walls.

Just my experience, but home remodel projects are usually a loosing propostion right from the start. Too many people (architects who deal in home remodels as well as the home owners themselves) want you to totally change how the structure of the building work, and aren't willing to pay for the exploration necessary to see what the existing structure consists of.
And of course, your expected to send them a bill for about 1/2 of the hours you actually spent, becasue afterall, this 'isn't like a real project' (said an architect to me one time on a house).

how big are the loads you're dealing with? 4klf? what were the original loads?
how did the geotech come to 2ksf? what was their exploration/testing process?

The bore log says that the claystone is at 7 foot. He wasnt sure whether the footing rest on the claystone or they sandy fat clay above it since the main floor is about 4 foot above grade. If it is on the claystone then he is willing to bump it up to 2500 psf. We also have addition that will be on drilled pier. The contractor is complaining because the existing is on footings and the addition is going to be piers. I am just doing whatever the soil engineer say.
