Demolition work is scheduled to start Saturday on the building at 1029-1033 Davis St. that was destroyed by fire Sunday.
Fire Division Chief Dwight Hohl says the fire department and the property owner's insurance investigators are making progress in trying to determine the cause of the blaze.
The demolition contractor hired by the insurance company will load material from the rubble onto a flatbed truck and carry it to another location where the investigation into the cause can be continued.
The contractor will also remove unstable sections of the building's Davis Street facade, likely by the end of the day Saturday.
The city is requiring the demolition and removal of the structure including the building foundation.
Temporary fencing currently located on Davis Street will be moved to the sidewalk and the street cleared, once the building has been demolished, Hohl added.
