I don't understand what kind of "weep holes at intervals" one block/brick below the dpc is? The structure isn't cavity and it's a solid concrete floor .

Thank you

Air bricks I can understand as part of some sub floor ventilation, not sure why there would be weep holes.
 
Under the installation is the damp proof course one block below this is the weep hole. This allows any rising damp below the DPC to escape.

What I'm struggling to understand what is this weep hole looks like . My builder wants to put a air brick connected to a tube ...

Rising damp does not escape through weep-holes.

Weep holes are for draining cavities. Air bricks are for ventilation on the other side of the wall. Two different purposes.

If you are working to drawings, then the plan drawer has probably just lazily copied the text from his last job and not proofed read it.
 
You’re not putting an extension with a solid floor on a building with a suspended floor by any chance?
 
Are you using a gas membrane? i have installed weep vents at ground level 2 course below DPC on a few jobs (as drawing).
 
Thanks .

Solid single block construction. External insulation. No suspended floors . All solid . I haven't seen gas membrane mentioned - I think it's mentioned standard DMP.

I'll have to check with the structural engineer.
 
Some feedback! As per woody suspicion...it was indeed a drawing error by the structural engineer....
