Pouring concrete on rebar 1

[karimom]

I have a project where the contractor chipped out the concrete around the rebar of a lintel (door way for a bathroom). They realized it wasn't in the right spot and repoured the lintel on top of the existing rebar. The architect wants an engineer to review what happened and provide assistance on if the situation is structurally adequate. I have no issue with it except that the rebar was exposed and could potentially induce corrosion down the road. They've also added a 2-L4X4X3/8 to strengthen the opening which is fine.

I'm just looking to see if anyone has any experience with this exposing of the rebar and repouring after.

How is it any different than the re-bar being exposed prior to pouring in the first place?

The corrosion is likely not an issue. Rebar is often exposed, left in place, cleaned where necessary and repoured when doing concrete restoration work. However, I would be much more concerned with how it was repoured. Was the bonding surfaces sound, what type of surface preparation on the bonding concrete surface was completed, what type of material was the area patched with, was a bonding agent used, what was the patch geometry, was there enough clearance around the rebar, etc....

we do this all the time with repairing bridge substructures. In your case, I assume the contractor properly prepared the surfaces and used the right material, so you should be fine
