The Surface Surveillance Systems Inspection Report details an assessment of the ASDE-3 radar system at the DEN Remote site on August 20, 2024. The primary objective is to extend the life of ASDE antennas by 10 years and towers by 20 years. The inspection evaluated the physical condition and functionality of site assets, including the tower, antenna system, and shelter buildings. Critical issues identified include the tower paint being in poor condition (100% repainting needed) and the elevator being unusable and unsafe due to missing stop plates and a compromised ladder. Moderate issues include the need for saddle clamps on grating and replacement of a broken hydraulic assist for the hatch door. Minor issues include a lock needing replacement on the door underneath the rotodome. Recommendations include painting the entire tower, installing saddle clamps, replacing the hydraulic assist, and installing a new stair tower. The report provides a deficiency breakdown and specific observations for each section, aiding decision-making for necessary repairs and upgrades.

Titan Environmental Solutions, Inc. (TES) conducted a lead paint chip analysis at the Denver CO ASDE Tower, 8500 Pena Blvd, Denver, CO 80249. Three paint chip samples were collected and analyzed by SGS Forensic Laboratories, an AIHA-accredited lab, using EPA Methods 3050B and 7000B. All three samples tested positive for lead, with concentrations ranging from 480 ppm to 3,700 ppm, classifying them as Lead-Containing Materials (LCMs). TES recommends that any disturbance of these materials comply with OSHA's Lead in Construction Standard (29 CFR Part 1926.62), requiring lead hazard communication trained workers and lead-safe work practices to prevent exposures above the Action Level or Permissible Exposure Limit. All lead activities must adhere to applicable federal, state, and local regulations.

The Federal Aviation Administration (FAA) seeks professional paint contractors for the Denver International Airport ASDE Tower and Shelters. The project involves preparing, removing, and repainting the structures to a 12 mil thickness using Sherwin Williams Polysiloxane XLE-80 or an approved substitute. The 90-foot tower must comply with FAA AC 70/7460-1M Obstruction Marking and Lights, while shelters will be white. A lead-containing materials survey identified lead on the tower frame, necessitating compliance with all federal, state, and local regulations for lead-based paint (LBP) removal, storage, transportation, and disposal. Contractors must be SSPC QP-2 certified and provide a work plan, paint submittal, QP-2 certificate, and safety plan for working aloft. The work requires strict adherence to safety standards, including fall protection and containment procedures, with no on-site restroom or utilities provided.
