Are duct bank spacers designed for concrete only applications or can they be installed without? An EE told me that since they were not adding concrete to the duct bank that spacers could not be used because the Civil Eng said they needed to meet certain "what ever" to patch the 3' wide asphalt where the conduit lay. Can chairs cause them from being able to pack the dirt down to a certain hardness and cause a bad patch. I was wanting chairs as the specs said but the EE came back with this answer. Has anyone heard of this before? Throwing 30 conduits in a hole on top of each other seems crazy with no spacing. 480V feeders.
