Croke Park Stadium

Case Study

CROKE PARK HILL 16 – Banagher Precast Concrete were commissioned to provide a precast alternative to the original cast-insitu design. A precast alternative was sought as it was deemed the only construction method that could achieve the extremely challenging project completion programme put forward by the client, the Gaelic Athletic Association.

Notwithstanding the clear advantages of an efficient precast solution, it was always clear that the programme would remain extremely challenging. The structure was of a complex and irregular geometric nature, requiring some very large, heavy and geometrically complex precast units in order to yield the structural and architectural characteristics of the outline design put forward by the design team of consultants and architects.

Banagher Precast Concrete commissioned Exstrado, a South African consultancy to prepare the detail design calculations and construction drawings for all precast elements to the structure. This included everything above foundation level. Exstrado then became an extension of Banagher Concrete for the duration of the project, working through the Christmas period to prepare production drawings and progress the design.

John Sisk & Sons duly commissioned Banagher Precast Concrete for the design and supply and installation of the entire redevelopment as a redesigned precast structure. These precast concrete elements included precast columns, spine beams, hollowcore flooring, vomitory walls, terrace units, control suite, courtyard walls, stair core walls, lift core walls, stair flights and landings as well as any other miscellaneous precast elements required.

Banagher Precast Concrete’s manufacturing process was characterised by:

  • Sophisticated mould work fabricated by state of the art methods by highly qualified tradesmen
  • State of the art self compacting concrete mixes with high early strength development
  • Sophisticated and fully automated reinforcement cutting and bending methods resulting in accurate and optimised bending of reinforcement

Detailed in-house checking of design deliverables was executed to ensure consistency between the design deliverables and the final product. The decision to use self compacting concrete on all elements in Croke Park was based on the requirement of a uniform blemish free finish to all exposed concrete surfaces, this coupled with the complex geometrical shapes and density of reinforcement gave it enormous advantages over conventional concrete.

On the basis of this project, the Institution of Engineers of Ireland nominated Exstrado Consulting Engineers as a finalist for the 2004 Irish Chartered Engineer of the Year Awards.
