Alternatives to raised access flooring could be:
Suspended Ceilings – hard to relocate/ maintain services because all must occur at a high-level;
Skirting – running cables along skirting boards around a room is adequate for small rooms but not an option for larger rooms or those which require more than a few small cables. Hard to maintain or access;
Poke-through – running cables down power poles between floors provides no flexibility and is almost impossible to access. This method also requires cutting large holes into concrete and the building itself;
Pre-cast Trunking – Common practise in the 70’s, this method involves steel trunking to be cast into structural slab along pre-defined runs. There is again no flexibility or the option to change set-up.
