Dublin conference centre

摘要

Dublin's National Conference Centre (NCC) is not just an iconic structure, it is also an incredibly complex and challenging building. Located in Dublin's Docklands area, overlooking the River Liffey, the ￡183M project consists of two levels of basement car parking, a 45m × 60m exhibition hall at ground level, a 35m × 47m exhibition hall at first floor level with an auditorium stacked on top, and public access from three separate levels. The use of steelwork has also come to the fore on this project as a series of trusses located on each floor were seen as the best structural answer.rnBuilding and designing a structure with three large open areas, all on top of one another, required considerable interaction between the team members. The complex structural steel design model designed by O'Connor Sutton Cronin took 9 months to develop. From it the project was priced by Fisher Engineering. Further development of the model (a joint effort between O'Connor Cronin Sutton and Fisher Engineering) took a another 9 months.rnAll of the concrete structure in contact with the ground was specified as GGBS concrete to meet the 100-year design life criteria and the requirement to provide resistance to sulphates in the ground. The basement structure is designed as a Grade 2/3 environment and this is achieved using a Type B structure (crack width design) to BS 8102 1990. The external cladding system is designed such that the perimeter steel columns are in a fully internal dry environment.
