The Center for the Performing Arts, Carmel, IN
Palladium Concert Hall, Tarkington Theater, Studio Theater, Parking Garage

Palladium, The - Carmel, IN Z1S1

The $126 million dollar Center for the Performing Arts in Carmel, IN, includes the Palladium Concert Hall, the Tarkington and Studio Theaters and an adjacent parking garage. We were hired as the prime MEP engineering firm to design the systems for this Performing Arts complex, the Palladium Concert Hall, Tarkington Theater, Studio Theater plus parking garage and energy center. Particular attention was given to the integration of the building systems within the architectural elements of the Palladium. The geometry of the oblong audience chamber, together with numerous level changes, demanded that the ductwork and other system components be coordinated thoroughly with the structure and other building elements. Revit was used to design the MEP systems and avoid clashes with other building elements, resulting in seamless MEP systems design that compliments the building’s elegant architecture.
