Mitigation strategies, cost estimation, and documentation – EMI/RFI Design Support

At each project milestone, for EMI/RFI Design Support, Vitatech reviews project documents (i.e. conceptual and schematic design, design development, construction/tender documents, and commissioning and certification). This review includes analyzing building construction techniques, electrical and mechanical schematics, as well as civil and utility plans.

Careful, ongoing assessments
Lab data sheets and equipment tool lists are reviewed, in tandem with manufacturer’s installation guides, to identify EMI/RFI thresholds and design needs related to protecting equipment, personnel, and patients from elevated magnetic fields. This information is then presented in a series of diagrammatic graphics, finite element method modeling, simulated predictions, and narratives analyzing and documenting each design phase’s progress.



Schematic Design

Schematic Design Support

  • Initial reviews of the design package, specifically placement of laboratories, classroom, MEP
  • EMI Modeling as necessary for fully realized electric distribution systems within schematic design drawings
  • Review size and proximity of elevators and lifts in reference to EMI sensitive instrumentation
  • Review civil plans for existing transportation routes (i.e., loading docks, high volume highways, parking garages, railways, subways, etc.) and predict their EMI impact
  • Review utility plans for existing/future and underground utility services
  • Identify EMI locations and review all research equipment
  • We provide feedback and design criteria for future design phases to all trades

Design Development

Design Development Support

  • Provide final EMI models of all building electrical distribution systems to include systems not previously included in Schematic Design
  • Final design recommendations and cost estimates
  • Draft technical narratives and specification documents to be reviewed by the design team
  • Review of all design development drawing and specification packages for compliance of EMI/RFI criteria
  • Participate in design workshops

Bid Ready Documentation

We assist our clients with build to design and performance based bid-ready documents.

Predicted Levels

Determine the Impact of Quasi-Static DC Emissions.

Predicted Elevator and Vehicle DC Emissions As a Function of Distance

Large and small ferromagnetic masses in motion produce quasi-static DC geomagnetic field perturbations in the sub-extremely low frequency (SELF), 0 – 3 Hz band.  These perturbations radiate from the source, generating quasi-static DC (EMI) in sensitive scientific, medical, and research equipment. Vitatech and the University of Alberta in Edmonton, Canada, collaborated on measuring the quasi-static DC fields from a passenger elevator in steel and concrete buildings. These field levels depend on the size, mass, and speed of the moving ferromagnetic object. It’s important to assess the distance from elevators, loading docks, and roads during preliminary design stages.
