What is Raised Floor?
Also called raised flooring, access flooring, or raised access computer flooring, a raised floor is a construction model in which an elevated floor is built above a building’s original concrete slab surface, thereby creating a hidden void between the two floors that is used for the passage of mechanical and electrical services.
There are two general types of raised floors:
- Traditional/Standard Access Floor (Post and Panel Raised Floor)
- Low Profile Access Floor (Cable Management Floor)
The type of raised floor needed depends upon several considerations:
- Application type (data center, office, medical facility, industrial site, etc.)
- Cooling system/air distribution setup
- Cabling/Wiring needs (flexibility, routing, distribution and delivery)
Let’s take a look at each of these raised floor types and what they are designed
for.
A traditional raised floor used for underfloor air distribution
The Construction Specifications Institute (CSI) and Construction Specifications Canada (CSC) have designated the following Masterformat numbers and titles for this standard type of raised flooring:
The traditional post and panel raised access flooring system was introduced in the 1960s with the primary purpose of providing cooling and air flow to the large computer mainframes of that era, as they ran exceptionally hot.
A traditional access floor creates a sealed air space (called a plenum) between the raised access floor and the subfloor. The plenum is there to accommodate and contain underfloor air distribution (UFAD). These floors can be installed at a variety of heights, from 6 inches (152 mm) to 4 feet (1.3 m), or higher.
The height of the posts is dictated by the volume of cables and other services to be stored beneath the raised floor; the typical height is somewhere between 24 inches (610 mm) and 48 inches (1219 mm).
To meet industrial demands of low profile systems, traditional post and panel manufacturers have attempted to bring their raised floor heights, in some cases, down to four inches. However, at that height, post and panel flooring still doesn’t offer the usable space or flexibility that low profile systems have as a standard.
The key components of the traditional post and panel flooring system are as follows:
-
Post (pedestal): This is a vertical, adjustable post that supports the floor panels mentioned above. The panel is attached with screws to a steel post at each corner (4 posts per panel). The posts are usually bonded to the subfloor with an epoxy resin-based adhesive and with mechanical fixings, if required. - Stringer: This is a horizontal piece of hardware that connects to the post head, adding additional lateral floor support, if needed.
- Additional structural support and lighting are often needed when a floor is raised enough for a person to crawl or even walk through.
- Added requirements may include fire suppression systems and cable tray systems.
After installation, the floor panels can be covered with a variety of flooring finishes, such as carpet tiles, vinyl files, linoleum, high pressure laminate, rubber tiles, wood, marble, and stone and ceramic tiles.
Should repairs or changes need to be made to the services under the floor, a special tool and a trained worker will be required. This tool (called a floor-puller, tile lifter, or suction lifter) has a curved handle atop a large suction cup. To open the floor, the suction lifter is attached to an individual tile and then lifted with brute strength. For carpet tiles, a hook and loop lifter is usually used.
There are several things to consider when using a traditional raised access flooring system.
Structural problems, such as rocking panels or gaps between the panels, can cause significant damage to equipment—or even lead to the injury of personnel. It is vital to look out for problems like these by conducting regular inspections to check out the structural integrity of the flooring system. This practice will help identify and mitigate any problems before damage is done or people are hurt.
These types of problems can be mitigated if the installation process is done correctly in the first place. During installation, special attention must be paid to the condition of the subfloor. The subfloor should be clean of all debris and be as level as possible. And the walls surrounding the raised floor need to be as square as possible. This will minimize the need for cutting the panels, which, in turn, will minimize panel rocking and gaps.
Another thing to avoid is flooring that does not meet the load demands of the work space. Load ratings range from 1,000 to 25,000 pounds. The panels can be mixed by using lower-weight panels in the lighter load areas of the building, while using higher-weight panels in heavy load areas of the room.
In summary, traditional post and panel raised access flooring systems are a good solution when heavy duty systems like air distribution are required. Outside contractors or highly-trained inside personnel will be necessary to service these floors.
This flooring system does not provide easy access to the wires, cables, and pipes under the floor. The individual panels are heavy and require the use of a special tool to access the plenum. Also, it is not advisable to pull too many floor panels at once, as the entire floor can lose stability; this can be a major problem if you are several feet off the ground.
There are several other types of raised flooring systems available that are a little different from the traditional post and panel model. These primarily have a telecommunications/data center application.
In today’s world, raised access flooring is primarily used in IT data centers and computer rooms where there is a requirement for UFAD. All cabling and wiring are routed under the floor as well.
A telecommunications facility is usually made up of continuous lineups of equipment cabinets. These data centers often have the most populated installation configuration in terms of square foot area, and, therefore, the heaviest floor load anticipated for a raised floor system.
Moreover, data centers are often located in remote locations and are subject to physical and electrical stresses from sources such as fires and electrical faults.
In data centers, isolated air-conditioning zones are often associated with raised floors. Perforated floor tiles are placed beneath computer systems to channel cool air directly into them. In turn, the computing equipment is designed to draw conditioned air from below into the room. Then an air conditioning unit draws the air from the room, cools it, and forces it back beneath the perforated tiles of the raised floor, thus completing the cycle.
Traditional post and panel raised floors are not used in a telecommunications/data center environment. Several different types of raised flooring systems can be employed instead and are bullet pointed below.
-
Stringerless raised floors: With this system an array of pedestals (posts) provide the necessary height for routing cables and also support each corner of the floor panels. No horizontal stringers are required -
Stringered raised floors: This system is composed of an array of steel pedestal assemblies (that consist of a steel base plate, a tubular upright, and a head) that are uniformly spaced on 2-foot centers and mechanically fastened to the concrete floor. -
Structural platforms: The components of this system are constructed of steel angles or channels that are welded or bolted together to form an integrated platform used to support equipment. -
Truss assemblies: This system utilizes attachment points to the subfloor to support a truss framework on which the floor panels rest. The truss has high lateral strength and transfers lateral loads to the subfloor with less strain than a vertical pedestal assembly does.
