The demolition began around 8 a.m. at 1133 Mission St. and is estimated to continue until Saturday afternoon, said Granite Excavation & Demolition Inc. Project Manager Tom Piepras.
The fire started Tuesday around 7 a.m. in a three-story building and kept blazing until about 1 a.m. the next morning, said fire officials. Piepras sai the building burned from the inside out and left 50 feet to 60 feet of brick wall standing without much support.
“It left the building like a water balloon, just ready to burst,” he said. He said his crew of five or six people will have to remove the brick by hand as a precaution.
Officials said the one-alarm fire injured two firefighters who are now in stable condition. The building, possibly an old dance hall for an Irish fraternal organization was undergoing renovations, but the cause of the fire is still unknown, said San Francisco fire Lt. Mindy Talmadge.
Mission Street between Seventh and Eighth streets will remain closed until the process is finished. Officials are hoping to have it reopen by this weekend.
