Hi mooyong

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
