A raised access floor is a type of floor used in modern buildings (such as IT data centers) with a high requirement for servicing to carry cables, wiring, electrical supply, and sometimes air conditioning or chilled water pipes. Additional structural support and lighting are often provided when a floor is raised enough for a person to crawl or even walk beneath. This type of floor consists of a gridded metal framework or understructure of adjustable-height legs (called "pedestals") that provide support for individual floor panels, which are usually 22 feet or 6060cm in size. The height of the legs/pedestals is dictated by the volume of cables and other services provided beneath but typically arranged for a clearance of at least six inches or 15cm.
Interchangeable. A panel share the same size which can be assimilated quickly and easily.
Flexibility in the distribution and positioning of all the technical plants. A technical area with obstructions reduced to a minimum facilitates plant movement with resulting cost reductions.
The system is equally effective for newly-built structures and those undergoing renovation. In the latter case, the floor can be installed without touching the pre-existing surface.
Dry installation. This reduces costs and installation times as well as reducing the extent of the building works required.
Plant maintenance: it provides an easy and immediate opening, maintenance and closing.
Flexibility in the installation of new work stations for plant and equipment and in the movement of those previously installed.
Combination of raised floor with other technical fittings, such as mobile partitions and false ceilings, for a complete intervention in interior design.
Benefits relating to writing down costs and tax costs. The raised floor can be included in the same category as office furnishing and mobile partitions.
