e labor and equipment to change out eighteen (18) transmission-class tangent poles ranging from 75ft to 90ft in length. This is NOT a reconductor job. All existing transmission class poles to be replaced are wood; all new transmission class poles will be steel and provided by OMU along with all other necessary materials. These poles support two 69kV transmission line(s) and up to one 15kV distribution under-build line. There are also numerous telecommunication attachments on several of the poles. All 69kV lines will be de-energized throughout the project; however, portions, if not all, of the 15kV distribution under-build line(s) will have to remain energized resulting in several of the pole replacements being considered 15kV HOT work.
