Engineered joists have been calculated for use on the extension we're building but having seen an example of them I'm not so keen.
How do I stand if I want to change them for C16 timber as far as building control are concerned?
Will they require us to submit more calculations with regard to loads, deflection and that kind of thing or would the standard joist tables that can be found almost anywhere be sufficient for the BCO?
It's only a clear span of 4m with 400 centres.
Thanks
