This contractor has been given a correction to seal top plate penetrations on several inspections. They tried to comply with this job as you can see the gray stuff around the raceways. When I asked about the cable I was told that the cable is "existing" and as such, it is not the contractors responsibility to seal that penetration.

We had a similar issue in a commercial building where decades of renovations and no inspections from the municipality resulted in the fire separation of a service room being Swiss cheese.

"But we didn't do that!"
I didn't say you did, but it needs fixed and you're here, so guess who is probably getting a change order.
"Oh, OK."

The owner saw the value of using the guy who was already there and knew how to firestop. He made a nice little bit of change off fixing up the service room.
 
If during Demo, or Construction, the contractor exposes or uncovers, what could be a safety hazard, I will not sign it off until the safety issue is resolve.
Filling the Annular space with draft stop or firestop materials can be a safety issue.
 
Who installed the metal strap over all the new work and the cable (old work)? Awful nice of them but doesn't seem necessary, is there a code requiring that protection?

Sort of...In Cali it could be a seismic thing too....


R602.6.1 Drilling and Notching of Top Plate


Where piping or ductwork is placed in or partly in an exterior wall or interior load-bearing wall, necessitating cutting, drilling or notching of the top plate by more than 50 percent of its width, a galvanized metal tie not less than 0.054 inch thick (1.37 mm) (16 ga) and 11/2 inches (38 mm) wide shall be fastened across and to the plate at each side of the opening with not less than eight 10d (0.148 inch diameter) nails having a minimum length of 11/2 inches (38 mm) at each side or equivalent. The metal tie must extend not less than 6 inches past the opening. See Figure R602.6.1.
Exception: Where the entire side of the wall with the notch or cut is covered by wood structural panel sheathing.

ICE, I agree with your request on both code issues, 50% over-notch rule and fire blocking. The 6-inches past the opening I didn't pick up on.
