Project Detail: Pharmaceuticals- Vibration

King of Prussia, PA

GSK is installing a mass spectrometer in an existing facility and needs to identify locations where the equipment will not be affected by existing conditions which will potentially interfere with proper operation of the machine. The installation location is challenging for a number of reasons. First, it is not on the ground level of the building which is not the ideal circumstance for the location of a highly sensitive piece of laboratory equipment. Second, it is on two slab bays surrounded by corridors which are susceptible to pedestrian footfall throughout the day. Third, there is an elevator nearby which seems to be in need of service that is possibly introducing unnecessary vibration into the installation location.

We reviewed the facility including building structures such as slab/column/beam/girder types and configurations, the proposed mass spectrometer installation locations, and all of the potential sources of vibration—the HVAC plant, the mechanical systems, the elevator shaft, and the corridors. We measured the ambient vibration in the floor slabs and columns as well as the vibration introduced into the floor slab with heel and weight drop impacts, footfall at various rates, with and without the air handling units, and elevator operation under several loading conditions. We compiled the results into modal maps and presented all of our data to the client. The resolution to our findings is ongoing.
