Principles for routing services
Concentration of services to exploit the ceiling height
By using open cable trays, cables etc. become easily accessible to service. However, one should remove the dust from the cable tray now and then.
Services in linear zones
It is important that it is easy to open up the ceiling alongside service routes, as these need to be easily accessible. A suitable solution is to have panels that can be fully opened adjacent to the service routes. See also "6 Power and data".
Services located centrally in the ceiling tiles
If exposed elements of the services are placed in the ceiling tiles, symmetry can be achieved by placing them centrally in the tiles. If the panels are large or if it is otherwise suitable, installations can be placed centrally in halves or quarters of the panels instead. Following the specific design and installation instructions ensures a good end result regarding technical and aesthetical performance. General advice as well as system specific guidelines should be considered. The unique character of the ceiling systems with concealed or semi-concealed grids (edge details C, D and DG), regarding alignment and levelness/evenness, is maintained by ensuring the tiles precise positioning. Hence, integration in such systems requires extra care from the designer and the installer.
Services located at intersections
Symmetry can also be achieved by placing the exposed elements at intersections between tiles. However, as a result of this, the demountability of the ceiling is often reduced, as more panels are obstructed.
