    Structural bonding in a BMO

    What are people's thoughts on exposed structural steel bonding in a BMO where each dwelling is fed from a Ryefield on a private network? Would you bond it once at the main incomer, once at the Ryefield or however many times at each downstream CU? And I guess, same question for gas!

    Carrying out some EICR on a commercial/industrial site. Previous records state the structural steel is bonded, and visually I can see 4x 25mm Earth wires leaving the main earth bar, I cannot trace the one going to the steel , though I suspect one of these does. How do I prove this? Is it a case...
