Sisk has carried out numerous projects for Allergan in Co. Mayo including, construction of a new production facility. This included a warehouse & ancillary accommodation. Relocation of an existing and local access road and the construction of a new circulation route to the existing Allergan facility.

In 2014, Sisk completed the MD14 Project for Allergan. This required the installation of a new ‘Fill Line’ within the existing facility, incorporating all necessary demolitions, cleanroom and service installations. The new Fill Line is a replacement of the existing facility within the live plant. The location of the works within the live pharmaceutical environment meant that the project involved extensive planning and enabling works to allow the works to proceed in close proximity to Allergan activities and operators, without causing disruption from construction activities.

In 2013 Sisk completed the construction of cleanrooms (walls and ceilings are all cleanroom modular system) and plant area to facilitate the production of a new medical product. The new cleanroom facility was constructed within an existing vacated warehouse.
