Hi, I have my PA coming in a week. There are some topics I am not very clear about and hope someone can help me with them.
1. Geotechnical Report.
I have read Site planning and Design chapter 7 thoroughly but when it comes to the real geotechnical report I am still confused about when to use shallow/deep foundations.
The answer to this question based on the picture is individual footings.
Piles are wrong because 'piles are a type of deep footing that are required when upper layers of soil are unstable and the building must be built on bedrock. Because the boring logs show loamy soils within 6'-10' of the surface, pile foundations are not the best choice.'
Doesn't loamy soil have low bearing capacity? How do I know if sand with fragment of clay is suitable for shallow foundation?
2. Occupant Load
- 6 conference rooms, 900 sf each,
- 15 supervisor offices, 440 sf each,
- 2 electrical closets, 300 sf each,
- 4 pantries with some chairs and a bar, 250 sf each.
When calculating occupant load on this floor with the program above, why are pantries counted as accessory to occupancy B and use 150, instead of 300 as accessory storage area?
3. Passive Cooling in Hot Arid climate
Why is stacked ventilation also considered? I am assuming it would only work during night time since during the day we would want to avoid hot dusty wind.
This is a question from Ballast and all of them are correct ...
In many desert areas of the country, the climate during the summer is hot and dry during the day, but cooler and quite comfortable at night. In such an area, which of the following building conditions would be desirable?
- Exterior shading devices
- Dark color on the south facade - this can't be right .... right???
- Light-colored roofing
- Insulation on the exterior of masonry walls
- Vented openings facing the prevailing wind
Thank you so much for answering my questions : )
