Completion of Acceptance for the Metal Roofing Sub-Project of Terminal 3 at Guiyang Longdongbao Airport
As the golden autumn month approaches, Guiyang Longdongbao Airport The sectional acceptance of the metal roofing works for Terminal 3 was successfully completed on August 30. Leaders from the Guiyang Municipal Construction Engineering Quality Supervision Station visited the project to provide end-to-end supervision of the acceptance process. Also in attendance were leaders from the Command Office of the Phase III Expansion Project, representatives from the Terminal Area Project Management Department, as well as project managers from Guizhou Provincial Architectural Design Institute Co., Ltd., Shanghai Construction Engineering Supervision & Consulting Co., Ltd., Zhejiang Dadi Steel Structure Co., Ltd., China State Construction Third Engineering Bureau Group Co., Ltd., and Guizhou Provincial Analytical Testing Research Institute, among others.
The metal roofing project for Terminal 3 comprises the A-area finger piers and connecting corridors, the B-area main terminal building, the cantilevered eaves, and the C-area connecting corridors, with a total area of 110,000 square meters. The primary systems include the roof structural system, the construction-layer system, the intelligent skylight system, and the siphonic rainwater drainage system. The main materials used are steel, aluminum-zinc coated sheet, vapor-barrier membrane, thermal-insulation rock wool, polyurethane rock wool, TPO waterproofing membrane, stainless-steel gutters, honeycomb aluminum panels, and aluminum-manganese-magnesium alloy panels, among other construction-layer materials, totaling 698,000 square meters in installed area and 3,160 tons of steel. The intelligent skylight system features electrochromic glass covering 6,000 square meters—making it the first application of this cutting-edge technology at a domestic airport—allowing the glazing to dynamically adjust shading and daylight transmission according to indoor lighting needs. To ensure timely completion, the Terminal Area Project Management Department held multiple focused problem-solving meetings, established dedicated task forces, meticulously reviewed construction organization plans, and overcame numerous challenges. Technically, measures such as prefabrication of materials and increased equipment investment were implemented, while limited working hours and constrained workspaces were optimized to fully meet all scheduled milestones. At the same time, the project team maintained stringent safety controls for high-altitude operations, achieving “zero accidents” throughout the entire metal-roofing process—from start to finish.
This project makes rational use of BIM technology and innovative construction methods were employed to model the primary and secondary purlins and the exterior eaves of each work face, which were then divided into several modules for full-scale assembly on the ground prior to integrated lifting. For the exterior eaves, aluminum panels were installed and sealed on the ground, enabling the entire finished unit to be lifted and installed in one go, achieving a single-stage, seamless installation. This approach not only enhances construction efficiency but also improves construction quality, thereby providing critical technical support for meeting the established schedule targets.
Under the long-term guidance of the leadership of the Guiyang Municipal Construction Project Quality Supervision Station, the meticulous planning and efficient management of the Third-phase Command Center, and the concerted efforts and close cooperation of the general contractor, the supervision unit, and all participating construction units, Guiyang Airport The acceptance inspection of the metal roofing subproject for Terminal 3 has been successfully completed.
