- 10. Wexford Festival Opera 2001 - Arup Acoustic and Theatre Consultants, Carr & Angier appointed to advise client and OPW in specialist disciplines 2003 – OPW asked to evaluate proposal for extending the old theatre “The building project is the only option for the future development of the opera festival, and the unique quality of the festival requires expression in a building of unique charm and identity” Jerome Hynes Wexford Opera House
- 11. Client Brief Fundamental to the aspirations of WFO was that the theatre should provide high quality acoustic environments to international standard, to support and enhance the creation, production and performance of opera in the 21st century. The emphasis for the room acoustic was that it should support and help to showcase the young vocal talent that has traditionally been a fundamental part of the Festival, but that this should be balanced with a fine orchestral sound Wexford Opera House

- 30. Structural Concerns Significant logistical difficulties of building a large building in a very confined space with access by streets that were only 5.0m wide between domestic houses. In choosing the principal material, for the structure the criteria that were most significant were: dealing with large spans, rapid erection and adaptability. A particular issue was the treatment of balconies within the Main Auditorium which were cantilevered. Wexford Opera House
- 31. Structural Design Integration of Services in Balconies Tight construction programme – 1 year to build superstructure. The design of the main auditorium structure was kept separate from the architecture and acoustical enclosures. This allowed the design of these areas to be refined while the steel frame was erected.
