Alexion, Purification Facility

Concept, basic and detailed design and CQV for a multi-product single use purification facility housed in a standalone building, with black utilities fed from the existing CUB.
About this project

The new building is designed as a standalone facility independent of the existing manufacturing building with fallow area for future development. The single use design results in a flexible facility, suitable for multiple product introduction, facilitating a fast track project with minimum time to construct and commission. The concept and basic design phases were delivered to a very aggressive schedule of 14 week, including submission of planning, EIS, fire and DAC to the local authorities. This was achieved by close co-operation of the DPS and client representatives, an intensive technology transfer period in the USA and rapid mobilisation of a high quality engineering team in DPS. The following major elements formed the scope of the project
