Description
TMG completed work on two levels of roofing at this historic Air Traffic Control Tower. The top-most portion, constructed of steel and metal, was re-sealed, scraped and then painted. The lower portion of the roof served as a catwalk. On this level, the existing pavers were removed, the substrate repaired, and new roofing membrane and walk-pads installed.
An intricate four-story scaffold was erected to serve as a basis for yet another scaffold that functioned as a swing-stage, which was raised and lowered by means of 12 cables and six motors. This configuration allowed movement of the platform between the different levels of the tower without blocking the view of the air traffic controllers as the ATCT roof was refurbished. In addition to the use of netting, care was taken to protect the lower level roofing of the terminal, in particular the glass-covered awnings over the entrances.
Once work on the exterior of the ATCT was completed, the crew moved inside to perform climate control measures of the “attic” space immediately below the uppermost roof. This phase involved spraying insulation, sealing the core area and painting.
