I've been taking it easy and planning for a few days
First, I had the 911 home to change the oil and finally install a pedal that I bought a few years back. I always had trouble with heel-and-toe in this car because of the pedal positions. The 917/RSR replica pedal has a convex shape that brings the middle of the pedal further out. The brushed aluminum looks blingy with the mostly black interior
Now, the work has begun
When we moved into the house, the garage was a 1+1. A previous owner walled in the carport side of a detached garage+carport. Unfortunately they just built the walls on top of a slab that ran from the house, across the breezeway and into the carport. This means that any water that collects on the 400sqft slab would run away from the house (good) but into the new wall (bad). Not surprisingly the bottom of the wall is now having some problems because of rot and rust.
So... I came up with a plan (see the diagram). First attempt was to cut the slab (red arrow in top image) as close to the garage wall as possible so that less water could collect. From the decreased size of the puddles in the garage for the past few years, this helped.
Here's the slab ledge left at the bottom of the wall after cutting. The saw could get about 1.5" from the wall.
But about 20years of water damage took its toll so I decided to completely rebuild the wall as a permanent solution. After talking with a couple concrete guys, the plan, shown at the bottom of the diagram, is to construct a code-compliant foundation without replacing the slab. Basically, 1) jack the roof 2) demo the walls 3) cut (red arrow in bottom middle image) and demo the edge of the slab 4) trench and pour footer 5) course of CMU and 6) rebuild the wall
This will also allow me to replace the slab at a later date without disrupting the wall.
Here's how it looked yesterday when I quit for the day.
