Many of the building's classrooms haven't been updated since it opened as a high school six decades ago, reports The Daily Herald.
The building housed Forest View High School until it closed in 1986 because of declining enrollment. The facility now houses six specialty programs.
In addition to upgrading classrooms, the $15 million project will improve heating and cooling systems and technology wiring.
A 420-square-foot security vestibule at the northern entrance and a 5,680-square-foot addition within an interior building courtyard will be used as a new staff training facility are also included in the project.
The multipurpose space also will be available for student and community use. It will be a gathering spot for a variety of events, classes, meetings, professional development and rentals.
The renovations are set to be complete later this year.
