INVESTIGATIONS are under way into a fire that destroyed a shed-like telecommunications hub on the roof of the Redland City Council building at Cleveland on Saturday.
Seven crews of firefighters responded to reports of smoke billowing from the roof of the council's administrative building on the corner of Middle and Bloomfield streets about 10.30am.
A council spokesperson said the structure had caught alight during a planned electrical shutdown for maintenance.
"The Optus battery at the telecommunications hub was involved in the fire," the spokesperson said.
A Queensland Fire and Emergency Services spokesman said the battery room on the top of the four-storey building was well involved in fire, with small explosions coming from the room, when crews arrived.
The spokesman said fire investigation unit members went to determine the cause of the fire on Sunday morning. Their investigations were continuing.
Firefighters were on scene until about 12.40pm on Saturday.
The QFES spokesman said the building had been evacuated and firefighters wearing breathing apparatus went onto the roof to put out the fire.
The council spokesperson said it was business as usual at the building after the fire, with staff given the all-clear to return to the building on Saturday afternoon.
"There was some water saturation in the second floor kitchen, facilities services area on the first floor and the stairwell near the goods lift, however that has been addressed by cleaners," the spokesperson said.
A section of Doig Street was blocked off due to the incident.
