to inspect the tunnel. A preliminary visual inspection by CTL found corrosion on the steel beams and minor cracks in concrete walls. On August 23, the MTA agreed to commit $39 million of its own funds to fix the Archer Avenue and 63rd Street Lines, of which $14 million was given to the Archer Avenue project. Had the UMTA funds not been restored, the MTA would have absorbed the cost by cutting back other projects in its $8.5 billion capital program. On April 9, 1986, the head of UMTA stated that if the 63rd Street and Archer Avenue lines were not completed, he would demand that the NYCTA refund more than $700 million in federal aid used on the projects. The federal government paid for two-thirds of the $1.23 billion spent on the two projects. In June 1986, CTL issued a final report that found that the tunnels of the Archer Avenue and 63rd Street Lines were structurally sound. The report had been ordered by the MTA after UMTA stopped payments on $75 million in grants for the projects, which were 90 percent complete. While the grants were frozen, for a year, the MTA spent $22 million of its own funds to complete existing contracts and to maintain them. The study was requested to show that it was possible to fix leaks and cracks in both projects and an improperly altered ceiling girder in the 63rd Street Tunnel. If the study was approved, work projected to resume in January. It found that there were minor flaws in the projects, such as flaking concrete on a portion of the Archer Avenue tunnel wall, and uneven welds in the altered girder in the 63rd Street Tunnel. The report recommended some rewelding, the removal of stalactites, filling air pockets in some sections of concrete, the removal of debris, waterproofing, and the use of weak electrical charges to prevent corrosion of steel beams. In August 1986, a study by Knight Associates, which cost $300,000, was scheduled to be released. The study analyzed damage done to the switches, signals, lights, pumps, ventilation fans, substations, third rail and escalator and elevator equipment that resulted from years of moisture, vandalism and neglect. Damage was worse in the Archer Avenue line, where electrical equipment was damaged by a rainstorm in 1984. On February 6, 1987, NYCTA President David Gunn announced a proposal to spend $41 million on the
