3 As the construction of TTIA’s Terminal 3 advances, the terminal and office buildings, Hangzhan North Road, and the North Concourse are all simultaneously under development. The project has reached its peak construction phase, with over 30 large cranes of various types operating concurrently, proceeding in full swing. The North Concourse Taking Shape The North Concourse, scheduled to be completed in the first phase of Terminal 3's development, is currently undergoing the erection of steel structures and reinforced concrete works, as well as the installation of the structure and curtain walls of the airbridges. With the steel structures below the third floor nearly complete, the external appearance of the North Concourse is gradually taking shape. Subsequent work on the fourth floor and roof structures will follow, extending from Terminal 2's Zone D and increasing passenger service capacity upon completion. The airport exit route has been redirected to Hangzhan North Road for traffic maintenance during the next stage of Terminal 3's construction. The vehicular and drainage box culvert structures beneath the road are nearly finished, and the works for the roadbed, side ditches, and overpass are in progress. Once Hangzhan North Road is complete, the current airport exit route on the south side of Terminal 3's construction site will move there to facilitate the South Concourse construction, while the access route stays unchanged. Pioneering RPS Overcomes Column Erection Challenges The area above Terminal 3's third floor features a large-span steel structure supported by 16 colossal columns, each towering 19 meters and weighing 200 metric tons, along with the trusses atop them, providing the foundation for a double-curved, waveshaped roof spanning over 100,000 square meters. While the first four columns were successfully assembled, challenges emerged during the assembly of the third column due to its distance from the third floor's edge surpassing the reach of conventional cranes. To address this, the project team proposed adopting the "Rail Platform System (RPS)" during the bidding stage, marking its first application in Taiwan. The RPS entails installing a track above designated columns and beams, allowing a mobile platform to move flexibly along it. Cranes are placed on this platform, enabling adaptable roof lifting operations based on construction progress. This method significantly reduces the required platform area, thereby saving time and costs associated with platform assembly and disassembly. During the construction of the giant columns and roof structure, four sets of RPS equipment are to be installed to enhance project execution efficiency. 機場動態Airport in Motion ▲ 航站北路鋼樑吊裝施工。 Erection of steel beams on Hangzhan North Rd. 正在進行中的北登機廊廳空橋安裝作業。 Ongoing installation of airbridges at the North Concourse.
