This article is about Communication Tower Installation and Commissioning of OSP Telecom Distribution System as per International Codes and standards.
Communication Tower Installation and Commissioning Checklist
Installation
- Verify that all fabricated steel sections are match-marked for field assembly with designating numbers or letters corresponding to the field erection drawings.
- Ensure that the towers material does not contain hollow tubular steel members as part of their structure.
- Verify that all anchor rods are fusion bonded epoxy coated to eliminate corrosion. The coating shall be 500 to 625 micrometers (20 to 25 mils) dry film thickness.
- Verify that the outer ground ring composed a minimum of #2 AWG (35 mm²) solid tinned copper wire and buried not less than 0.8 m (2.5 feet) below grade level and at least 0.6 m (2 feet) outside foundation and tower footings.
- Verify that all tower legs and anchors are bonded to form a grounding electrode system, which shall be bonded to the building grounding system per SAES-T-887 and Standard Drawing AA-036391.
- Verify that each tower leg and anchor is identified with labels. The labels shall be located in a clear location such as the bottom of the tower and top of anchor.
- Verify that alternate sections of aviation orange and aviation white paint is used on the tower to provide maximum visibility of an obstruction by contrast in colors.
- Verify that Lighting units meets the specified intensities, beam patterns, color, and flash rates specified in FAA AC 150/5345-43, except where modified by SAES-B.063.
- Verify that Flashing red beacons and steady-burning obstruction lights is installed to be used during the hours of darkness, during periods of limited daylight illuminance and/or reduced meteorological visibility.
- Verify that double obstruction lights (L-810) are installed horizontally at regular intervals at or near the top of tower that is 60 m AGL or less.
- Verify that (PVC) conduit is used for physical protection of a ground wire.
- Ensure that the ground resistance of the grounding electrode system not exceed 2 ohms for Communications Tower(s).
Precommissioning
Verify that all Pre-Commissioning Phase Quality Control Activities are complied.
