Rigging and Assembly of 15 Air Handling Units
Client: Kirby Group Engineering on behalf of Janssen Sciences Ireland
During a €300m expansion project for Janssen Sciences, Wm. O’Brien was responsible for the rigging and assembly of 15 air handling units (AHUs). Involving a complex lift and shift operation, the AHUs needed to be manoeuvred and assembled in a tight environment, whilst also working around other teams in the facility.
The AHUs came in a number of sections, each weighing up to 2 ton. The AHU sections were brought to the entrance and skated into the building. Where possible, we used an electric forklift to safely raise them on to a temporary second floor steel platform. When it was too tight to work with the electric forklift chain blocks were utilised instead. The AHUs were then positioned, assembled, and bolted together.
