What are the alternatives to using a raised access floor?

The alternatives are:

.  Suspended ceilings. High level trunking runs are above the ceiling and services drop down at the 
             required locations through service poles. However any relocation, maintenance etc is at high level 
             thus causing major disruption to the office area.

.  Pre-cast trunking. This method was common in the 1970s. Steel trunking is cast into the structural 
             slab or topping screed along pre-defined runs. No flexibility to cater for future changes.

.  Skirting and Dado trunking. Steel or plastic trunking which runs around the perimeters of individual 
             rooms. Adequate for small rooms but very limited for larger areas, also limited cable capacity.

.  Furniture. Specialist furniture which encompasses in-built service runs. Expensive and limited to 
             vicinity of furniture runs.
