Can you give me a rough idea for the cost per foot for a monopole telecom tower assuming no special ground conditions and same for a guyed tower? Example: a 250' monopole used for telecom antennae, dishes, whips etc. And before you wonder what on earth I am doing in this website with this Cell Tower 101 question, let me explain that I am a municipal tax assessor and am trying to get a basic idea of the contruction costs for these types of towers. Cost is only one way we value these structures and I'd like to get some reasonable good information so that I am addressing their value properly. Thanks!
