It is often forgotten that the raised access floor forms the backbone of every facility.
Raised access flooring is normally only a small fraction (2-3%) of the total cost of the building cost. However, purchasing the correct type of raised floor system can make a substantial difference in construction costs, time to delivery and the return on investment. This is especially true in a Data Centre environment.
It is often forgotten that the raised access floor forms the foundation of the data centre facility. It safeguards a company’s Server Rack equipment, provides a plenum to distribute air to areas that require cooling, while also allowing for moderate cable management. Until recently, these were the added values that raised access floor solutions offered, being accustomed to a type 600×600 mm grid floor system.
However, what if you were able to design the raised floor around the equipment layout being the focus, placed on a modular floor sub-structure having various sized panels to optimise the floor space? Such a floor would generate additional income (or revenue) by allowing for placement of more equipment in the same room.
Bergvik’s Iso Floor with its unique and modular sub-structure, made in South Africa, allows for different sized floor panels to be installed, offering more flexibility and ensuring more access to the void space under the floor. The system use 70% less pedestals than with standard 600 x 600 grid floors at a 15kN/m² loading. This allows for less congestion and obstructions under the floor, providing easier airflow underneath the floor and reducing energy consumption by 30-40%. The Iso Floor can easily support loading of up to 40kN/m² by simply moving the pedestals closer together.
From a contractor’s point of view, the speed of construction is paramount. As Bergvik’s steel sub-structure only utilises 30% of the standard number of pedestals and can be installed without panels, other subcontractors such as electricians, fire suppressant installers and even CRAH-unit installers can start their work sooner. In a 1 000m² room, about 950 pedestals are needed with the Iso Floor system, versus over 3 000 pedestals with a 600 x 600 grid system at 15 kN/m². Another feature that reduces the cost and installation time of the Iso Floor system is the fact that only two grounding points are needed versus multi-point grounding with standard floors.
Quoting a prominent CFO of a large data centre: “With a cold aisle of 1 000mm compared to the standard 1 200mm, the Iso Floor allowed us to install 20% more Server Rack cabinets on the same floor area, thereby exceeding the revenue stream that we originally forecasted. Additionally, considering the money we saved by not having to purchase expensive stand alone frames for our heavy and specialised equipment, which was just supported directly to the Bergvik floor sub-structure.”
Bergvik’s Iso Floor also allows for future changes in the ever-evolving world of data centres by easily adapting its sub-structure to meet future equipment changes at a minimum cost. At the end of the day, it’s about getting a system that adds value and feeling confident that you are not only saving money, but preventing future cost and generating additional revenue.
The Iso Floor is considered a definite must for all data centre CFO’s who are serious about achieving high return on their investment.
In addition, Bergvik’s new Iso Flex-Grid structural ceiling system, made in South Africa, will be launched to the industry soon to provide for even more savings and flexibility in your facility.
