Raised access flooring systems are common in commercial spaces like data centers and offices. These systems provide a space under the floor for wires, plumbing, and heating, keeping everything organized and hidden. Over time, the floor panels may wear out, requiring replacement. This guide will walk you through the process of replacing access floor panels, ensuring a smooth and safe procedure.
What Are Access Floor Panels?
Raised access floor panels create a space above the original floor, allowing easy access to electrical wiring, cooling ducts, and plumbing. Common materials for these panels include concrete, steel, wood, or aluminum, and they can be customized to fit any space. You’ll often find them in offices, data centers, and schools.
Why Replace Access Floor Panels?
Here are some reasons to replace your access floor panels:
- Wear and Tear: High-traffic areas cause scratches, dents, and other damage over time.
- Improved Aesthetics: New panels refresh your office space.
- Changing Needs: Technology changes may necessitate newer panels for better airflow or efficient cable management.
- Ageing Panels: Older panels may become less effective and require replacement.
Preparation for Tile Removal and Replacement
Planning the Task
Before starting the replacement, consider:
- Why do you need access? Define the specific task or repair.
- How many tiles will you lift? Plan for the extent of the task.
- How long will the tiles be removed? Consider any disruptions.
- Who will be affected? Notify staff if they need to adjust their workspace.
- Alternative arrangements: Ensure access and egress plans for others if needed.
- Known hazards: Check for potential hazards under the floor, such as live cables.
- Physical fitness: Ensure you’re physically able to lift a panel (up to 15kg) while kneeling. Tile lifting should not be performed while lone working.
- Consider who may be affected by the removal of panels. Any lifted panels create a hazard that could lead to a fall into the void from height. A thorough risk assessment of the site should always be undertaken, and adequate safety barriers and signage should be present to mitigate these risks.
Required Tools and Materials
Make sure you have:
- Replacement access floor panels (ensure correct size and type).
- Panel puller or suction lifters: A pair of CE-marked vacuum suction lifters are recommended.
- PPE: Gloves and goggles for safety.
- Barrier and signage: Collapsible barriers and signs to prevent accidents.
- Measuring tape and marker: Ensure proper fit and track removed panels.
- Cleaning tools: A vacuum cleaner, paintbrush, and waste container.
- Light or powerful torch to inspect the void.
Step-by-Step Guide to Replacing Raised Floor Panels
Step 1: Assess the Situation
- Identify which panels are damaged.
- Consult drawings for floor layouts.
- Communicate with affected personnel and set up barriers/signs.
Step 2: Remove Carpet Tiles
- Lift carpet tiles from a corner, noting orientation for easy re-laying. The carpet is typically held down by a tackifier glue.
Step 3: Lift Raised Floor Panels
- Attach suction lifters to the panel and lift vertically. If the panel is tight, use a rubber mallet on the edges. Do not use screwdrivers or force to remove panels.
- Lift panels in rows, leaving single panels at 3-meter intervals for safety.
Step 4: Prepare the Space
- After removing the panels, clean any debris in the void with a vacuum.
- Inspect the support structure, check for loose pedestals or any signs of damage.
- Ensure fire barriers are intact and adjust if necessary.
Step 5: Install the New Panels
- Choose the correct replacement panel and place it in the void, using suction lifters to lower it carefully.
- Secure the panel in place, ensuring there is no wobbling.
Step 6: Clean and Finalize
- After replacing the panels, clean the surface and remove barriers. Ensure that carpet tiles are replaced correctly.
Step 7: Inspect Your Work
- Walk across the replaced panels, ensuring they are stable and secure. Double-check for any unevenness or loose pedestals.
Additional Safety Considerations
- Inspection before void access: Ensure lighting is sufficient, and check for live cables, sharp edges, rodent infestations, or water ingress.
- Fire barriers: Refit fire barriers neatly after working in the void.
- Leave pedestals intact: Do not remove or balance pedestals. If they become dislodged, seek help from a specialist.
- PPE: Always wear gloves to prevent cuts from sharp floor panels or pedestals.
Maintenance Tips for Access Floor Panels
- Routine cleaning: Keep panels free from dust and debris.
- Avoid heavy loads: Be cautious of placing heavy items on the panels, as they may warp or get damaged.
- Regular inspections: Periodically check panels for wear or damage, replacing as necessary.
- Professional help: For complex replacements or tight panels, seek professional assistance.
