EirEng were appointed by Dublin Aerospace to provide structural and civil Engineering consultancy services in connection with the refurbishment of the existing Polyglas building in Ashbourne.

The original building was constructed in the 1980s utilising a precast frame and was constructed in 3 stages. The refurbishment works required multiple interventions with the existing structure to facilitate the new internal operations.

As part of the works material testing on the precast concrete frame was undertaken to enable a structural assessment to be completed to inform the structural solutions for the refurbishment works. As part of the assessment, pyrite testing was also undertaken of the slab subgrade materials.

The structural interventions included raising the roof in a section of the warehouse to accommodate the operations associated with the new the chrome shop which strips and re-chromes the landing gear for commercial aeroplanes.

A section of the existing warehouse was also replaced with a new structure with an increased 12m height to accommodate cranes.

Internal interventions included.

  • 5 New tank runs with suspended walkways
  • New 1m deep machine plinths
  • New mezzanine for storage
  • Refurbished offices and accommodation

Externally the existing drainage was modified to suit the new internal layouts and also changes to the external layouts. This included the introduction of new soakaways as part of the surface water solution. The external works also included the construction of new substation and plant plinths.

EirEng detailed knowledge and experience of working with existing industrial buildings ensured the solutions were optimised from both a cost and programme perspective.
