Salt Lake City Hall is scheduled for a major three-year overhaul.

Crews with Big-D Construction will begin work June 6 on the castlelike building in the heart of downtown to restore portions of its sandstone facade, repair windows and strengthen earthquake protections, according to an announcement Wednesday by Mayor Jackie Biskupski's office.

"These key projects are essential to maintaining the building to a level that is consistent with its historic significance and to allow for continued use as Salt Lake's City center of government well into the future," the mayor said in the statement.

The 122-year-old structure, sometimes called the City-County Building or City and County Building, underwent a major seismic retrofit in the late 1980s. In 2014, the city provided additional funding to help the building withstand larger quakes and repair or replace some of the exterior sandstone.

Biskupski's office said the first phase will involve stone restoration on the tower. Seismic work also starts this summer and is expected to run through spring 2017. Lower floors of the building, meanwhile, will see work from mid-2017 to 2018.

Though soon to be wrapped in scaffolding, the Romanesque Revival-style structure will remain open to the public and continue to serve as City Hall during the renovation work, the mayor's staff said.
