NC A&T and UNCG Collaborative Building

Vitatech was commissioned by HDR Architecture in November of 2008 to perform an initial full-spectrum (EMI/RFI) site survey at the future location of the University of North Carolina at Greensboro and the North Carolina Agricultural and Technical State University’s collaborative building project: the Joint School of Nanoscience and Nanoengineering in Greensboro, North Carolina.

The site survey was commissioned during the excavation phase of the project after the announcement that the building was to feature various EMI-susceptible imaging instruments.  Vitatech performed an AC ELF, DC EMI, and RF site survey to measure the ambient magnetic field and radiofrequency environment on-site and to detect any unintended EMI sources before construction began on the project.  Due to the instrumentation (NMRs and other instruments) desired for the building, Vitatech provided target specifications of 1 mG RMS (for the NMR) and 0.1 mG RMS (for the Quiet and EM laboratories) during the survey.

The site survey confirmed that the location was an extremely favorable site for this type of building, with very low AC ELF magnetic flux density levels (approaching 0.0 mG RMS) throughout, very low radiofrequency levels, and the only source of DC EMI being the access road.
