As part of its ongoing investment programme the customer instructed ISG to refurbish the ten whisky maturation warehouses which make up the storage facilities at the Auchroisk site. Asbestos removal formed a major part of this project.


The Project

The asbestos insulation ceiling board tiles were removed, along with the suspended grid, insulation quilt, associated fixings and ceiling hangers. A working platform was constructed on top of the existing cask storage racking to gain access to the ceiling. Each warehouse was divided into three storage cells. To comply with current legislation, fire protective boards were installed in each cell. 

A deep clean was undertaken inside the cell of each warehouse to ensure that any fibres dislodged by ongoing wear and tear were safely disposed of. The external roofs of the warehouses were originally made of asbestos cement sheeting on a mansard roof. The sheeting was safely removed and replaced with a composite cladding. New gutters were installed to each roof along with new down pipes and connections into the existing underground drainage network.

The Added Value

The site remained live throughout the project, and the warehouses remained fully stocked with maturing barrels of whisky. To protect the casks a temporary working platform was built over them to allow construction works to continue with no impact and to act as a crash deck.

Auchroisk is a bonded site, which meant that Customs and Excise had to be kept up to date. The programme was set up to allow multiple warehouses to be worked on at a time, and Customs and Excise had to be notified when work was started on a new warehouse and when it was handed it back to the customer. The project was delivered on budget and ahead of programme.
