A late-night fire at San Diego State University left a campus building with $300,000 in damages, the San Diego Fire-Rescue Department said.
The department received a call at 11:20 p.m. Wednesday for a fire on Aztec Circle Drive, an on-campus building that houses the control room for all the air conditioning on campus.
Police said workers were repairing and reconstructing the building when the foreman said he saw a spark from one of the cutting torches, police said, and that spark started the fire.
Crew members attempted to put out the fire but when they were unable, they safely evacuated and called 911.
Once the firefighters arrived, the blaze had become a two-alarm fire. Firefighters knocked down the fire in approximately 45 minutes.
The blaze left the building and its scaffolding and construction materials damaged. Officials estimate the building suffered $200,000 worth of damages and the materials inside the building suffered $100,000 worth of damages.
