This communication site is located on Whitmore Mountain west of Nespelem. There is primitive road access to the site.

Existing Conditions

  • Tower is a Fire Lookout Structure that is being utilized as a communication Tower in combination of a manned Fire Lookout Tower.
  • The construction method and structural capacity of the tower base foundation is unknown. The construction method and structural capacity of the tower base foundation is unknown ICI cannot comment on the adequacy of the existing tower foundation. Tower base foundation displays some visual deterioration in the concrete piers. Tower anchor bolts show mild corrosion.
  • Mild corrosion is evident on tower assembly bolts.
  • The antenna mounts and antenna mounting hardware for several antennas are rusting.
  • No lightning rod is placed on top of tower.
  • The tower is in in compliance with the specifications for a class” A” climb facility as defined in the TIA-222-G tower design standard.
  • In general, the site is not adequately grounded. Sub-surface ground system cannot be verified. Site grounding is not in compliance and does not meet MOTOROLA R56 standards.
  • Site road access is good with winter access issues.
  • Site is not served by commercial Power. Primary power to this site is provided by a fixed angle solar array.
  • There is no emergency back-up power generator unit.
  • There is no equipment shelter is not equipped for environmental conditions. No climate control (HVAC) or dust control.
  • There is no security fence or anti-climb system in place to restrict unauthorized personnel from accessing this structure or deterring vandalism and theft.
  • Climb Warning signs, RF Warning signs and No Trespass signs were not posted.
  • Tower is overloaded in its current configuration per the requirement of the TIA/EIA-222-F or G Standards.
  • It is ICI’s professional opinion it will not be economically feasible to repair the tower to meet the requirement of the TIA/EIA-222-F or G Standard. Another cause for concern is that the existing lookout tower is not designed to be utilized as a communication tower and would require extensive structural modifications and the result would still restrict the CCT from any future growth.
  • All power, antennas, and radio equipment are mounted inside and affixed to the tower structure.
 

Initial Recommendations

  • It is ICI’s professional opinion it would be most feasible to upgrade the site by erecting a new tower 150’ self-supporting lattice tower and placing new 12’ x 30’ Prefabricated concrete equipment shelter with the emergency back-up generator housed in the equipment shelter.
  • This site location is a desirable location for Colocation. It also would resolve all site deficiencies and consolidate all antennas and ancillary equipment to a single structure.
