Steel to masonry ties

[Ay8452]

Hi guys,

 

My engineer has specified wall ties for a steel column (C4.1) in his drawings attached. He has specified wall ties from this column to the inner skin (which we've done) and from this column to the outer skin also (which we haven't done by mistake). So there are no ties from the external skin block work to the steel in this section only. There are wall ties in the rest of the cavity wall (inner/outer leaf) as specified.

 

We haven't built the next storey up (highlighted green) and will make sure correct ties are used when we do.

 

Is this a major structural issue? Have messaged my engineer and am awaiting a response. Anyone with more experience care to share their thoughts to hopefully ease my nerves.

 

Thanks!

For building regs you normally need ties 225mm from wall opening jambs at 450mm vertical centres (I think). 
 

More than likely an issue…
