Victoria's director of Engineering & Public Works says it's still an active fire zone at the gutted building at Government and Pandora.
His message to the public is -- 'get off the site'.
As Victoria fire crews douse stubborn hot spots, demo crews are preparing to remove another portion of a wall at the former Plaza Hotel.
Fraser Works says it continues to be a challenge to keep the smoke levels down.
The sheer amount of debris at the site, have kept investigators searching for clues at bay.
Fraser admits this is a big learning curve professional and they're proceeding with caution to ensure mistakes aren't made.
Meantime - VicPD say the search continues for the building's caretaker.
Vic PD officers are looking for tips on Mike Draeger. Police are also looking for a photo of the missing man for circulation.
