Cable Route guidelines

Cable Route guidelines

Cable Route guidelines

(OP)
How to approach cable routing for HVAC works? Should it be started after or before the duct layout has been prepared? How the clashing between cable tray and duct, pipelines can be avoided?

RE: Cable Route guidelines

Construction coordination is the job of the General Contractor.

RE: Cable Route guidelines

Ductwork above ceilings should have very few vertical transitions; having unnecessary bends and transitions makes the fan work harder and the system becomes less efficient. The cable trays I've seen are always run at an elevation below the ductwork all but eliminating conflicts. Then during construction, the GC will offset small duct branches, piping and your cable trays as needed to make everything fit.

To answer your question, it does not matter.

IF you are that concerned about conflicts, the best thing to do is layout where you want the cable trays then talk to the HVAC designer to coordinate.

Being in a position where I frequently review designs, I cannot tell how how often I've seen plans where it is clear the engineers and architects have not coordinated with each other. It's as if they are each in their own little worlds.

RE: Cable Route guidelines

Will your designers not be modelling the system in 3D? I have noticed that with everyone working within the same model (or space) any conflicts will be identified and remedied long before they become a problem in the Field.
If you are not all working in the same model, you obviously must have good communications, and have designers who care about their work.
