Specifications include, but are not limited to: General: • If there are immediate tower or anchor concerns that need to be addressed, the Contractor must contact BIT/State Radio Engineering immediately for a decision on the corrective action. The Contractor will take pictures of the issue and send the pictures to the BIT/State Radio Engineering. BIT must provide approval before the Contractor can begin work to address the concerns. • Any immediate corrective action deemed necessary by the Contractor with the approval of the tower owner will be at the tower owner's additional expense, billed on a time and materials basis. The Contractor will provide the amount to the tower owner's representative for approval before work begins. • The Contractor must not use sub-contractors for any work. • The Contractor will visually inspect the tower structure, guy wires, and anchor points (no digging) and address any safety concerns or hazards before proceeding with any work. Tower Inspection work: • The Contractor will mobilize a two-person tower crew and all necessary tools/equipment to the job site(s). • The Contractor will perform an initial check of plumb and tension measurements for each tower and document those readings. The Contractor will also note the condition of all guy wire preforms or guy wire hardware clamps, turnbuckles, turnbuckle safety cables, turnbuckle attachment pins and cotter key keepers, thimbles, fan plates, and ice protection equipment. • The Contractor’s tower crew will climb the tower and inspect all tower members, bolts and hardware, antennas, mounts and hardware, antenna feedlines and feedline mounting hardware, feedline connectors for proper sealing of connector junctions, and feedline grounding. The Contractor’s tower crew will check moisture weep holes, if applicable. • The Contractor will visually inspect safety climb cables, hardware, and attachments, if applicable. • The Contractor will perform a visual inspection of Federal Aviation Administration (FAA) lighting for proper function and verify the proper operation of the photocell. • The Contractor will visually inspect the overall site condition. • The Contractor will document all work, in writing and with pictures, for all inspection items above. • The Contractor will provide a detailed written report with accompanying pictures within 30 days of the completion of the tower site inspection work. • The Contractor will clean up and remove all unwanted trash and debris accumulated during the inspection. Anchor Inspection work: • The Contractor will mobilize a two-person tower crew and all necessary tools and equipment to the job site(s). • The Contractor will connect a safety chain to the guy wire anchor fan plate back to a suitable, substantial anchor such as a vehicle or anchoring device before beginning anchor shaft excavation, so that if there are any anchor shaft issues, the safety chain and anchoring device will hold the tower in place. • The Contractor will excavate around anchor shaft down to the concrete anchor block, inspect, and notify BIT/State Radio Engineering staff of any immediate issues at the anchor points. • Upon completion of excavation and inspection, the Contractor will backfill soil around anchors and anchor concrete block in 18" lifts with compaction for each lift. The Contractor must backfill the soil to the same level or slightly higher than the surrounding soils. • The Contractor will provide written documentation and photos to provide complete details of each anchor point. Anchor Guard work: • The Contractor will mobilize a two-person tower crew and all necessary tools and equipment to the job site(s). • At the tower sites where anchor guard systems need to be installed for anchor corrosion protection, the Contractor will procure and install anchor guard systems. • The Contractor will document and provide initial readings of anchor guard systems in a written report to BIT. • The Contractor will clean up and remove all unwanted trash and debris that was accumulated during the civil work and installation of the anchor guard systems.
