Raised floor systems

The right floor should be strong, yet cost effective

Telecom operators around the world depend on Bergvik to deliver and install

critical flooring infrastructure to protect their networks from downtime and

damage caused by sudden earthquakes or flooding. Bergvik, a world-leading

raised floor supplier, offers a series of raised flooring systems engineered

for use in all seismic zones. Adapted to accommodate heavy equipment

and designed with room to expand, the Bergvik Iso Floor is a flexible,

secure and cost competitive solution for your central office flooring needs.

Complete product packages

Custom designed to match the equipment on which it is mounted, the Bergvik

raised floor system can be delivered as a complete package, including standard

options such as stepless brackets and cable ladders to expedite installation

and to securely organize cabling to and from the equipment.

Advantages of raised floors versus overhead mechanic systems

A raised floor system is engineered for optimal access to

network wiring and cabling. Floor panels are easily

removed for servicing or supplementation and large

spans between pedestal supports simplify installation

and access to equipment underneath. An overhead

mechanic system, on the other hand, has a less

integrated service pathway that makes access difficult

when adding or repairing wiring, as well as increased

labor and expensive hardware to “suspend” wires and

cables in the ceiling.

Seismic areas with very high risk for personal

injuries and network failure. Shakes and

earthquakes measuring up to 9 on the

Richter scale can occur.

Areas with no or low seismic activity. Serious

earthquakes are very unusual.

Areas with higher risk for personal injuries and

network failure. Shakes and earthquakes mea-

Secure any OEM equipment –quick delivery and fast serviceThe Bergvik raised floor product package also offers secure solutions for

any OEM equipment installed in the central office. Bergvik will provide

a design proposal within three weeks following receipt of equipment

drawings. After the order is approved, we can ship the custom seismic

frames within four to five weeks.

Proven mechanical strengthBergvik has developed and adapted a series of three different raised

floor designs to accommodate all seismic zones. To further verify all

structural calculations, we submit the floor and bracing structures to

dynamic full-scale laboratory tests in accordance with NEBS GR-63 (IEC

68-2-57) and NEBS GR-2930.

The base model of Bergvik's raised flooring is built from a stable

framework of zinc-plated pre-fabricated steel that is bolted together,

without welding, for optimal flexibility. This floor system meets the

requirements for non-seismic zones. The 800 mm panel depth allows

for optimized cabinets to line up back-to-back and be securely

mounted on top of the floor.

Pre-cut panels for cable intake, stepless brackets, and cable ladders

are standard options that expedite installation in the central office.

Bergvik recognizes that time is money.

Raised floors for areaswith higher risk of seismic activity

Bergvik's floor design for NEBS Zone 1–2 offers the same stable

construction as our base model but with additional reinforcements

to accommodate a higher risk of seismic activity. Strengthened with

a 60x60 mm pedestal anchored to the sub-floor with steel plate

connections between primary and secondary steel sections, this

model fulfills the requirements for seismic reliability according to

NEBS. The floor has passed both calculated stress as well as dynamic

full-scale tests in accordance with NEBS GR-63 (IEC 68-2-57) and

NEBS GR-2930 from Bergvik.

The Bergvik raised floor designed for NEBS Zone 3-4 is the most secure product

on the market today. The addition of solid bracing frames anchored to the

concrete sub-floor provides the strength and stability to withstand severe seismic

activity. This Bergvik raised floor system fulfills all the requirements for seismic

reliability according to NEBS. The frames have passed both calculated stress

as well as dynamic full-scale tests in accordance with NEBS GR-63 (IEC 68-2-57)

and NEBS GR-2930.
