How we fix an auditorium
Auditorium spaces are designed to accommodate large audiences. As such, they tend to have wide spans and are multiple-stories high to arrange seating, sightlines, and acoustical requirements. Raised stage/dais floors and special lighting equipment are often required as well. Typical features of Auditorium space types include the list of applicable design objectives elements as outlined below.
Sloped Floors: Sloped floors, with level terraces for each row of seating, help provide the proper sightlines from the audience to the stage. Note that the bottom and intermediate rows should be directly accessible from entry levels.
- Fixed Seats: Typically, fixed seats with tilting upholstered seat and back, integral arm and tablet arm are provided with articulated back for maximum occupant passage space between rows. The seats may be fully upholstered or wood contoured outer back and seat shells with wood armrests with tablet arm option and aisle light option at row ends. Wheelchair access option-removable seats in sections of two and accessible end chairs for mobility-limited occupants should be provided.
- Special Lighting: Dramatic lighting systems include front lighting, foot lighting, spotlights, follow spotlights, beam lights, and floodlights, and a projection room/booth with manual and programmable lighting controls, and space for the spotlight operator. Lighting systems should be flexible to accommodate various performance venues (e.g., lectures, plays, musical performances, etc.) in the Auditorium.
- Occupancy: Occupancy Group Classification is Assembly A1 or A3 as per IBC, with sprinkler protected construction, and GSA Acoustical Class A space requiring special acoustical design.
