I very confused about "erect,Hoardings,outlined "mean, I find and translate by dictionary but I can't understand.
The sentense " The contractor shall erect all necessary hoardings as outlined by the Owner"
Who know that please help me plase.
For "hoardings" see:
hoardings - definition of hoardings by the Free Online Dictionary, Thesaurus and Encyclopedia.
"A temporary wooden fence around a building or structure under construction or repair." [AME]
"[In BrE it regularly means] a large board used for displaying advertising posters, as by a road Also called (esp US and Canadian) billboard"
"Erect" means to build them.
"as outlined by the Owner" means "as identified by the Owner [client] in the enquiry/contract documents.
Hope this helps
