I have goal-post style steel frame in my extension. The uprights are buried in the internal blockwork with only the one flat surface standing slightly proud of the internal wall. The walls are being dot-and-dabbed with plasterboard. How should the steel columns be fire-proofed? Is it OK to just use 1 fireboard to cover the steel, d&d either side of the steel, then continue on with standard boards?
Fireboard over buried steels?

They will. It was the air gap behind the board due to the depth of adhesive that I was wondering about. It's about the same depth as the projection of the steel from the face of the blockwork so the board is tight to the face of the steel.
