Existing Conditions
This communication site is located on Stensgar Mountain across the Columbia river east of Inchelium in Stevens County. There is primitive road access to the site.

  • Tower is (2) short Rohn 45G tower sections erected vertical with 45G sections erected horizontal between that is being utilized as a communication 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.
  • 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 not 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 served by commercial Power.
  • There is no emergency back-up power generator unit on auto start controls.
  • There is solar and battery backup system installed.
  • Commercial power needs to upgraded and maintenance.
  • There is no TVSS or Transtector Surge Protector to protect communications equipment from transient voltage spikes installed.
  • The existing equipment shelter is inadequate. Equipment shelter is a CMU Block Building that is showing signs of age and deterioration.
  • Equipment shelter is not equipped for environmental conditions. No climate control (HVAC) or dust control. Signs of rodent infestation are present.
  • There is no security fence or anti-climb system in place to restrict unauthorized personnel from accessing this structure or deterring vandalism and theft.
  • Equipment Racks require anchorage and seismic bracing.
  • Climb Warning signs, RF Warning signs and No Trespass signs were not posted.
  • Tower is fully loaded in its current configuration per the requirement of the TIA/EIA-222-F or G Standards.
  • Tower Guy anchors and cables need replacement.
 

Initial Recommendations

  • 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.
  • 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’ Pre-fabricated 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.
  • The existing tower Rohn 45G tower sections could also be re-purposed in another more suitable application.
