We are estimating the telecommunication cabling on a 45-story condominium building on the ocean. The engineer has a one 1” conduit for the TV, and one 1” conduit for the telephone stacked between the floors going from one condo to an other every 7 floors then the conduit goes back to a telecom room. Isn’t there some where in the code that forbids this due to serviceability of the cabling, or security?
