THE South Burnett Regional Council plans to give Nanango's Library and Administration Building a much-needed upgrade.

The decision was made after a condition assessment report confirmed its poor state.

As the building has not been advanced since it was first built in 1960, it is in need for a substantial upgrade due to failing infrastructure, safety issues and mounting maintenance costs.

Mayor Keith Campbell and the council knows the building has issues that must be solved.

"We have been aware that the Nanango Library and Administration building has been failing for some time. Old wiring has contributed to two electrical fires at the site,” he said.

Apart from these safety hazards, Cr Campbell said he was aware of the building's overall deterioration.

"The air-conditioning unit is over 30 years old, regularly malfunctioning and in need of replacement due to the scarcity and high-costs of parts,” he said.

"The building's external, internal and sub floors have been severely damaged over time by ongoing water ingress, caused by multiple unstaged builds and failing internal box gutters.”

After a detailed condition assessment of the building confirmed its poor state, Mayor Campbell and the council have investigated three possible solutions: refurbishing the building, demolishing and rebuilding it, or building new on a greenfield site.

"The condition report, teamed with a cost-benefit analysis of the buildings ongoing maintenance needs have all indicated that it is time to upgrade the building. Costs involved with demolishing and rebuilding the facility were prohibitive,” he said.

"Council has determined that the best option is to progress with refurbishing the building and will soon be calling for tenders for the construction and modifications.”
