Bahamas Building Code - ASCE 7
Bahamas Building Code - ASCE 7
(OP)
From the Bahamas.gov website the 3rd edition is the most current I can find. In chapter 20 it references the ASCE 7-88. On the website it does say that the code is to provide minimum standards. Any reason I can't use at least the 7-05. The wind speeds have changed from fastest mile in the 88 to 3 second gust now. All the testing on windows, doors, etc. will be done using the 3 second gust pressures, right. It just seems crazy to me to use the 7-88. Has anyone else designed a building in the Bahamas recently?

1. The 3rd edition is the most current Bahamas Building Code.
2. The use of a more current ASCE is acceptable.
3. So for this job (which is in Freeport) ASCE 7-05 with V=150 mph and Exposure D.

Exposure D is required for coastal building zones based on the building code. Exposure C is then obviously to be used for those structures not within the coastal building zone. They added this. In addition, because the distance across each island is so narrow it is almost pointless trying to justify not being at the hurricane ocean line. Therefore, the recommendation is to use exposure D.
I guess I could still argue exposure C if I'm not within 1500 feet of the coast but it looks like I would probably lose. I guess my only saving grace is that this project is a really small masonry building with a mean roof height of less than 15 feet. Pressures aren't terrible but definately high.
