BLOOMINGTON, Ind. (AP) _ Indiana University has resumed renovation work on Franklin Hall after asbestos was found last month by construction crews.

The (Bloomington) Herald-Times reports construction resumed Aug. 17 following the asbestos cleanup that cost roughly $45,000. University spokesman Mark Land says construction workers had found unsafe levels of asbestos in caulk around windows.

Land says there was no indication of any harm done to construction workers by the asbestos.

The $21 million renovation of Franklin Hall started in November. Work is on track to be mostly finished on schedule by June 2016.

The building was constructed in the early 1900s and will house the university's recently formed Media School.
