Hey all,
I'm a long time lurker. I have a few questions to help me get started on my next project. I'm planning on extending my current patio slab and adding a cover (stand-alone roof) to the new slab. I will contract out the slab portion of the project, but would like to build the cover myself. The cover will be about 24'x12'. My first round of questions are related to the slab:

This is the cover I'd like to build.

The new slab will connect to the old and extend until about 5 ft off the fence line (setback).
1. What's the best way of attaching the old and new slab? I believe an expansion joint is best from what I've read on these forums. The soil conditions here in Miami are so that after digging about 6" you hit coral rock. I've dug holes for fence posts in the past and it's not fun.
2. What should be the depth of the slab and do I need a footing? 4"? The only structure that will be on top of the slab is the cover/roof.
3. What's the best way to anchor the posts to the slab? I was planning on using some type of Simpson anchor for the 6x6 posts, but not sure which ones. Also, would it be possible to anchor posts to the existing slab? I'm concerned that the existing slab (not sure if it's greater than 4") will be able to support the new structure.
I know these are all good questions for my local building dept., but I was I hoping to get some of the basics before I start the permitting process.
Thanks in advance for you help.
