Heathrow Terminal 5

RMF were recently requested to commence work on the existing flooring design to the walkthrough scanners, this was a continuation of our “Raised Monolithic Flooring” product development and were specified to do so.

Balfour Beatty and Mansell Construction design team selected RMF to assist them with a current issue they were experiencing with the recently laid flooring. It was established that the metal content of the system was adversely affecting the very sensitive scanning sensors. Several proposals were suggested including the utilisation of a plastic pedestal support whilst maintain the load capabilities.

A solution was agreed and implemented to allow the scanners to be commissioned safely and successfully.

Another example of the experience and flexibility RMF has working on all variants of raised access floor systems.

  • Rolling load tests on the completed floor erected at BRE. The floor comprised of 600mm square tiles laid out in 7 rows of 5 tiles, total 35 tiles, (Figure 4)

The component test materials were manufactured and assembled by RMF. The pedestal floor was constructed in BRE’s Structural testing facility by the flooring contractor RMF. Full test report available on request.
