//// CHALLENGE
As part of Exercise Arrcade Strike, NATO ARRC required a TOP SECRET secure working environment within a disused section of Charing Cross Underground Station.
The facility needed to be rapidly deployed inside an existing underground structure while meeting stringent security standards and an exceptionally tight delivery programme.

//// SOLUTION
To achieve TOP SECRET compliance within the existing structure, BeaverFit utilised the NPSA-accredited Bastion Secure Enclosure System to deliver a retrofitted secure working environment.
With just three weeks to procure materials and two days for installation, BeaverFit implemented an accelerated logistics programme supported by off-site manufacturing and pre-assembly to keep the project on schedule.
The underground location required meticulous planning, with materials routed via Imjin Barracks before being transported by rail for installation with minimal disruption.
