Builder's estimate for project to extend a house.

This comes as a note at the end of the estimate after these headings:

"TOTAL LOGISTIQUE / ADMINISTRATE / ETUDE
TOTAL DEMOLITION
TOTAL TERRASSEMENT
TOTAL STRUCTURE / GROS CEUVRE
TOTAL TOITURE / VELUX
TOTAL MENUISERIE EXTERIEURE
TOTAL GO HORS D'AIR HORS D'EAU
TOTAL PLATERIE / ISOLATION
TOTAL ELECTRICITE
TOTAL PLOMBERIE / SANITAIRE
TOTAL CHAUFFAGE / VMC
TOTAL MENUISERIE INTERIEURE
TOTAL AVEC SECOND OEUVRE
TOTAL PEINTURE / ENDUIT
TOTAL REVETEMENT (sol & mur)
TOTAL EXTERIEUR / RAVALEMENT
TOTAL CLE EN MAIN
TOTAL OPTIONS (Hors devis)"

"NB :
Tous les lots de mise en oeuvre ont été pris en compte pour les travaux de la maison uniquement afin d'optimiser ce chantier"

I am supposing tentatively that this means the work packages which involve "actually doing stuff" as opposed, for example, those which involve planning and possibly obtaining building supplies ... ? Even if right, I'm not quite clear what this note would thus mean.
