The recent carrier mergers are causing some constructability issues where integrating the radio equipment is concerned. Here in South Florida many of the sites no longer have ground space available and the adjacent properties have none to offer either. I've seen several approaches to getting the previous two carriers (now one) into the same or nearby lease area but many are costly. Add to this the issues that arise with power meters and separate accounts and you have some construction stalls that seem to go away only by throwing money in the hole. It seems that some shelter additions are costing more than a 1989 raw land. Besides using the tenant meters and stacking on platforms is anything else creative and cost effective going on somewhere else?
