Answer 1

This is not an easy question to answer. A lot of information is needed to answer it.

There are many reasons to isolate building foundations.
The major reason is to keep the building perpendicular to the ground during and after an earthquake. buildings laying down are not useful and often block streets and sidewalks. (for those how answer a question with "Huh").

If a new building, one would need to know:
1) Where will this building be built?
Isolators are not required in Massachusetts. They are
probably required in San Francisco.
2) What materials will be used in construction?
3) What are the dimensions of the building?
4) There are thousands of other questions needed to properly answer your question.

If you are planning to isolate an existing building the above information is also needed, You would be much better asking a qualified construction contractor.

if you are doing research for a paper or class, you may want to start your research at:

I found these articles doing a web search of "building isolators".

Answer 2

This config appears like a Dell Studio XPS 8100. if you're not any further in to gaming the GT220 may do a respectable activity on your videos and all. in spite of the undeniable fact that, if you're in to gaming then flow for the GTX 260. Dell promises 1792MB GTX 260. that is a sturdy card. To the better of my information, after I spoke to the Dell workers very last, he stated that they advance potential grant to compare the cardboard. each and everything else is appropriate contained in the config.
