Seismic Restraint

Building Codes have undergone remarkable changes in the past twenty years. Enforcement of the Seismic Provisions of the Codes is improving in many areas of the country, and will likely continue to improve.

SVS-Engineering provides full service Engineering support for the seismic restraint of mechanical and electrical equipment. This includes:

  • Floor mounted equipment, such as boilers, pumps, chillers, cooling towers, motor generators, and transformers;

  • wall mounted equipment, such as electrical panelboards; and

  • suspended equipment, including piping, ducting and conduit.
