The details for the suspension system, including the steel
members used to support the bottom of the unit, will need
to be determined by working directly with The VMC
Group. They will also help provide information regarding
the required external isolation system.

Anchoring

Lifting lugs should be used to anchor the unit at the ends
of each shipping split. Per the anchor requirements,
additional anchoring may be needed. If so, anchors will be
provided and installed on the unit. An example of a seismic
anchor is shown in Figure
Anchor selection meets or exceeds IBC 2000,2003, 2006,
2009, 2012, and CBC 2007, 2010 compliance requirements.
Special Inspection per IBC Section 1704 is required on all
installations. All anchors listed above must be installed to
meet compliance.
