To take advantage of latest state-of-the-art computer and communications technologies, equipment must be constantly upgraded. The Tech Floor series of raised access floor systems, offerd by Bergvik North America Inc. of Salisbury, Md., allows for such modifications and expansions. Each corner of the floor panel rests on a pad, which jointly locks the floor panel and the pedestal in position. Its optional Seismic Bracing Frame has been tested for Seismic Zone 4.
