Proposal to make something that is expensive; but simple in design, and easy to fix. Into something that is super expensive, complex to fix, and some may say.. cheeky in design.
- bdamm 11y agoIs it that expensive? In terms of raw materials it may cost more, but not double. The use of prefabricated parts (torso, limbs) reduces each tower's uniqueness and therefore complexity of repairs. Fabrication of unique beams is well within the repair capability of a mobile crew. Is the actual material cost of each tower a major component of a transmission line cost model? I am betting no; transmission wire, ongoing maintenance, land and rights acquisition, and monitoring probably make up the bulk of a transmission line's cost. Finding actual data on this is proving to be difficult, however.
- crististm 11y agoYou're preaching to the wrong audience. Not all people understand "engineering" or "maintenance". Reading comments here is like getting back in time several years ago when it was first submitted. Same comments, different people.
