Core Viewpoint - The article highlights the successful replacement of the control tower glass at Pudong Airport, emphasizing the importance of maintaining safety and efficiency in air traffic control operations while overcoming significant logistical challenges [1][2]. Group 1: Project Overview - The glass replacement project was initiated due to the aging glass showing signs of water seepage and fogging, which could potentially compromise air traffic safety [1]. - The project was executed without halting airport operations, requiring careful planning to ensure minimal disruption during peak flight times [5]. Group 2: Challenges Faced - Four main challenges were identified: the inability to use heavy cranes due to the tower's location, restrictions on scaffolding due to structural limitations, narrow internal spaces complicating glass transport and installation, and the need to work during low-traffic hours to avoid interference with flight operations [2]. - The project team had to innovate solutions to these challenges, including the use of a "spider man + steel structure components" approach to create a working platform without damaging the existing tower structure [3][4]. Group 3: Execution and Results - The project commenced on July 15, 2025, with the construction of a steel structure platform, followed by the actual glass replacement work conducted from September 15 to September 29, 2025 [5]. - The entire project was completed in 77 days, 33 days ahead of schedule, with no glass breakage during the process, showcasing the team's effective planning and execution capabilities [5].
