Written by GovTribe AI · Feb 20, 2025

This is a technical engineering drawing package prepared by EET, LLC for tower modifications to an Oakland County communications tower located at the Pontiac Social Services site in Michigan. The drawings detail modifications required for five sections of a 285-foot self-supporting tower, including converting X-bracing assemblies to C-shape assemblies in sections T5 (230-250 ft), T6 (210-230 ft), and T9 (160-170 ft), reinforcing diagonals in section T15 (50-70 ft), and reinforcing redundant horizontals in section T17 (0-30 ft). The 16-page drawing set, dated January/June 2018, includes detailed fabrication specifications, assembly details, and parts lists for all modification components.

The modifications require various galvanized steel angles, bolts, washers, nuts, and V-clamp assemblies. Key components include 120 5" V-clamps, multiple reinforcement angles ranging from 2"x2"x1/8" to 3"x3"x1/4", and hundreds of galvanized fasteners. The drawings emphasize critical safety notices regarding structural stability during modification work, requiring temporary bracing and adherence to TIA-322 and ASSE 10.48 standards for rigging plans. All steel must meet ASTM A-36 specifications with hot-dip galvanizing per ASTM A123, and field modifications must maintain minimum edge distances and coating requirements.
