The 106,000-square-foot project will include new classrooms, science and vocational labs, band rooms and art studios.
With St. Louis-based S.M. Wilson as the general contractor and Ill.-based Wight & Company as the architect, the expansion will resemble the existing buildings, including its terrazzo floors and steps, and limestone accents.
A vocational lab will be located on the ground floor and in the basement, serviced by a freight elevator. The ceiling of the basement will feature sound and vibration controls to keep lab noise from disrupting activities on the first floor.
The first floor will include the fine arts program, featuring visual, instrumental and vocal arts classes. The second floor will house the social studies programs.
Designs for the school also include a vegetation area on the roof surrounded by a glass curtain wall to be cared for by students.
Three 20,000 gallon outside water harvesting tanks will also be located at the base of the building for rain collection and irrigation for the field behind the building.
Officials from the contracting firm expect the project to be completed in the fall of 2012.
