It will be used for HVAC but there's a duct for data
cabling and another one for electrical cabling.
But it's a good option to have data cables running on
ladder racks. do you think it's fine to run powercables
on ladder racks? I've read a recommendation that say
whenever possible data and power cables should
intersect perpendicularly or at least keep them 6
inches apart if you have to run them parallel. I'm sure
it's cheaper to run them on ladder racks but you know
marketing people says it looks bad ... hide them.

No, HVAC will need an supply air plenum, and ADA, well
I'm out of the states but does it means American with
Disabilities Act? well, it doesn't apply here but I'll
take in consideration their recommendations ... one
more item for my to-do list.
