Evangel Cathedral

Upper Marlboro, MD

Client: RCI Systems

Completion Date: 1998

As the Evangel Church continued to grow, their existing multi-purpose building could no longer adequately fill their needs. They turned to SAA Architecture LLC. in a Design-Build format to design a new church with a 2,500 seat sanctuary, a full stage and theatrical capabilities. The program also includes, 20,000 sf of administrative offices, 30,000 sf of conference facilities, television and audio studios. The program anticipates the site for a 1,000 seat chapel, a grand foyer and a future school facility.

Polysonics provided acoustical, HVAC noise control, ceiling design to optimize the acoustics in the sanctuary. In addition to acoustics, Polysonics designed audio systems, video projection systems, and control systems for the 2,500-seat sanctuary, implementing full production and concert capabilities on a 160 x 80 stage. This project also included the design services for multipurpose and conference facilities.
