三亚凤凰“奇迹”：18个月，一座新航站楼拔地而起

Core Viewpoint - The successful completion of the T3 terminal at Sanya Phoenix International Airport in just 17 months marks a significant achievement in the construction of large-scale airport facilities in China, demonstrating the effectiveness of precise project management and innovative construction techniques [1][15]. Group 1: Project Overview - The T3 terminal has a construction area of approximately 120,000 square meters and is designed to handle an annual passenger throughput of 18 million, contributing to a total capacity of 30 million passengers for the airport [5][15]. - The project was completed in a record time of 17 months, significantly shorter than the typical 2-3 years required for similar projects [1][5]. Group 2: Challenges Faced - The construction faced seven major challenges, including tight timelines, complex urban traffic organization, extensive underground pipeline relocation, proximity to high-speed rail, limited working space, the need for 24-hour airport operations, and adverse weather conditions [3][5]. - The construction site was constrained by existing infrastructure, making it difficult to manage materials and equipment effectively [3][5]. Group 3: Management and Execution - The project management team implemented a granular breakdown of the overall schedule into eight main phases and over twenty specific milestones, assigning responsibilities and timelines down to the day [6][8]. - Continuous operation was ensured with over 200 workers on night shifts and the use of multiple large machines working around the clock [8][12]. Group 4: Innovative Solutions - A "three-step" method was used to navigate the complex underground pipeline network, involving scanning, on-site verification, and careful manual excavation in sensitive areas [9][12]. - Advanced construction technologies, such as membrane shell columns and real-time monitoring of structural integrity, were employed to enhance safety and quality while maintaining speed [11][12]. Group 5: Collaborative Efforts - The project required extensive collaboration with multiple stakeholders, including air traffic control and utility companies, to ensure smooth operations and timely completion [14]. - A flat communication structure was established to facilitate efficient coordination and feedback throughout the construction process [14]. Group 6: Impact and Future Prospects - The completion of the T3 terminal not only enhances the capacity of Sanya Phoenix International Airport but also symbolizes the acceleration of Hainan's free trade port development [15][17]. - The terminal's design incorporates local cultural elements and aims to improve passenger experience significantly, reflecting a broader ambition for enhanced connectivity and openness in the region [15][17].
