Little help with translation??

[Tony51]

I am currently building an extension to my property but I have hit a little snag.
The draughtsmans plan says "I.G. Lintels to have cavity trays d.p.cs"

Does this mean that cavity trays have to be installed at damp proof level where lintels are used, or do the trays go above the lintels.
Any help would be appreciated

They sit in front of the lintels.

lol - did I do those plans, I specify IG (Keystone) as they are better than Catnics for when you try and fit the curtain pole.

Cavity trays are required for these lintels and they are fitted above the lintel
