Structural survey

[Jilly]

I've just asked a structural surveyor for a quote on out stable conversion and he's come back with this

Building survey and assessment of suitability for reuse £500 Ok..

Design of structural elements for reuse £1750 Ouch 

 

But does this seem average?

 

Design of underground foul water drainage system £500  

Design of sustainable surface water drainage system to comply with planning conditions £750 

 

 

Is this average? Can I do it myself?

@Jilly Foul drains you can pretty much do yourself. The SUDs element may need an attenuation tank design but tbh it takes 10 mins to work out the rainfall for the gutter design, then once you know the volume you’re getting in a storm, it’s a lookup as to the volume needed based on permeability. 

 

If you’re reusing elements such as roof purlins and trusses then that can take some time as it has to be surveyed properly. What elements are remaining ..?
