Modular Mezzanines

The basic types of modular mezzanines available are free standing mezzanines and mezzanine systems that are supported by previously installed structures.  Free-standing mezzanines are self-contained and can be installed where adequate floor and overhead space allows.  They come complete with pre-engineered support columns, flooring, and stairs.  These systems effectively create an intermediate floor level throughout a portion of an existing building’s floor plan.  Existing interior columns and shelving units are often used to support new modular mezzanine floor structures, following a structural analysis to ensure safe installations.  For any type of mezzanine installation, the decking and framing elements need to be designed with a specific end use in mind.  Maximum floor load limits in pounds per square foot should be posted in a noticeable location to avoid exceeding the mezzanine’s structural capacity.

That there must be adequate open space within a building to install a mezzanine is intuitive, but the ability of existing utility services to support the extra square footage is not always as obvious.  Lighting, air conditioning, and ventilation system adjustments within the existing parent building may be required in conjunction with mezzanine installation.  Consideration also needs to be given to life safety codes as mezzanines are installed, particularly for larger projects involving a significant amount of floor space.  The nature of a building’s layout and original design intent can be significantly altered, triggering revised fire protection and egress requirements for building occupants.
