Specifications include, but are not limited to: labor and equipment to change out sixteen (16) transmission-class tangent poles ranging from 75ft to 85ft in length. This is NOT a reconductor job. All existing poles to be replaced are wood; all new poles will be steel and provided by OMU along with all other necessary materials. These poles support a variation of one or two 69kV transmission line(s) and one or two 15kV distribution under-build line(s). There is also numerous telecommunication attachments on several of the poles. All 69kV lines will be de-energized throughout the project; however, portions 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
