MSD Carlow - Pharmaceuticals


Expansion of the Carlow pharmaceuticals facility required a new production building. Soft ground determined the need for piled foundations. This called for a 9,000m2 piling platform constructed with imported granular fill. The contractor saved €58,000 on the platform with Tensar’s solution. 


  • €58,000 cost savings to the contractor 
  • 5,000 tonnes less imported aggregate used 
  • 35 tonnes CO2e reduction in estimated construction emissions 

Client's Challenge

Due to the presence of weak ground on site, comprising of made-up ground overlying glacial deposits, the building foundation was to be piled. The Geotechnical Interpretive Report proposed a 650mm thick granular fill working platform to support the 80 tonne piling rigs. The contractor sought to reduce the cost.

Tensar Solution

The contractor, Robert Quinn Ltd, contacted Tensar to ask for a value engineered alternative to the suggested working platform design. Tensar was able to provide a full design solution for a working platform that saved 45% of imported granular fill compared to the original design. The solution featured a Tensar Mechanically Stabilised Layer incorporating Tensar stabilisation geogrid to achieve the required bearing capacity with a thinner aggregate layer.
