Here was a case where the ICF header's reinforcing steel and concrete placement had not been inspected by the Building Department, nor was the reinforcing steel cecked and the concrete placement witnessed by a Professional Engineer or Registered Architect.

Because of some additional technical and legal issues, the Building Department required that the reinforcing steel in the header and the concrete strength be verified to meet design and code requirements.

In addition to its own weight the ICF header was also carrying load from roof trusses. We decided to use both analysis and testing -- and set out to remove the foam on the inside, and chip out the concrete to determine the location and size of reinforcing bars.

Based on our investigation, the alternate presented here required reinforcing the bottom of the ICF header and the sides of the supporting posts, the jambs, with structural steel channels.

I am depicting in the following a picture showing the longitudinal view of the ICF wall and the related design data.
