The Convention Centre Dublin in Spencer Dock, a Public Private Partnership project between the Office of Public Works and Spencer Dock International Conference Centre Limited, was successfully completed in September 2010. The project was a Design and Build project, with the design team novated to CMP, the design & build contractor. The building comprises two large exhibition spaces (with capacity for 2000 people each), a 2000 seater world class auditorium and numerous multi purpose meeting room facilities.
The building is unusual in that all of the above spaces are stacked vertically, with a limited number of structural support columns allowed in the functional spaces. The primary structural frame is structural steel, with the basement slab/retaining walls and exposed external slabs constructed in reinforced concrete.
O’Connor Sutton Cronin were the Civil/Structural Engineer’s on this exciting and challenging project, bringing nearly twenty years of experience working with complex structural projects to the project.
• Long spans with limited depth
• Indirect load path, i.e. Transfer trusses supported by transfer trusses
• Limited number of columns allowed
• Significant M&E ventilation duct distribution
Steelwork: Key Facts
• Approximately 7300 Tonnes of primary steel
• Typical floor plate truss span = 20m, with a structural depth of 2.3m overall
• Eight primary columns in the main exhibition spaces, with a maximum column load of 40,000Kn.
• Roof truss over main auditorium spans 47m
• Feature glass drum at main entrance spans 37m horizontally
• Design of floor plates is governed by dynamics (natural frequency)
