1) Q: The RFQ requests a price to clean different sizes of kitchen extraction systems (small, medium & large) but I cannot see that it states what size/length of ductwork is involved in these different size options? Are you able to clarify this please?

A: Please see the below table.

Sizes (m2) Small Medium Large Extra (Extra large or scaffolding needed)

Length x Width s<2.99 3<=m<9.99 10<=l<19.99 20<=XL or Extra requirement
