A scaffolding assembly includes a plurality of sound attenuating sheets, detachably mounted on a frame erectable substantially adjacent to a structure. The frame includes sheet supporting members. The sheet supporting members and the plurality of sound attenuating sheets when mounted on the sheet supporting members define an enclosed working area adjacent the structure, so as to affect a seal to substantially contain air pollution and other detritus, and noise pollution within the enclosed scaffolding assembly when erected adjacent to the structure. An inclined catchment ramp is mounted along the length of at least one of the scaffold working decks so as to sandwich each ramp between the working deck and the adjacent wall of the structure.
