Co-creating a Safe, Robust Taiwan: Taipei's New Construction Office Wins Construction Golden Safety Awards for Minquan Bridge Reconstruction Project
The Occupational Safety and Health Administration of the Ministry of Labor hosted the 2024 Construction Golden Safety Awards for Promoting Occupational Safety and Health, with the awards ceremony held on November 22, 2024, at True Love Garden Hotel in Taichung. The New Construction Office, Public Works Department, Taipei City Government earned the Excellence Award in Group E for Public Works with the Minquan Bridge Superstructure Reconstruction Turnkey Project! The Office's construction team aspired to set a model example for safe bridge reconstruction in Taiwan, demonstrating robust soft and hard power in construction. By implementing a unique “truss beam work vehicle” method to mitigate construction risks, the Office maximized workplace safety. This recognition by the country's foremost authority on construction safety holds special significance for both the Office and its construction team! Hsiao Chih-lung, Head of the Public Works Division at the New Construction Office, noted that many of Taipei’s older bridges built in the early days are now entering the reconstruction phase. Among the numerous bridges serving the city, Minquan Bridge, located on Minquan East-West Road—the first planned road in Taipei—connects key facilities such as Taiwan's first Songshan Airport and the privately- financed Neihu Technology Park. After 42 years of its completion, inspections have detected sagging at the cantilever joints between the P6 and P7 piers over the river, causing road surface subsidence and posing safety risks for drivers. After professional assessment, the New Construction Office initiated plans to demolish and rebuild the 215-meter-long section of the bridge between piers P5 and P8 with a new steel structure. This not only improves the bridge's structure but also enhances its seismic resistance. Hsiao Chih-lung elaborated that the Minquan Bridge reconstruction project, situated in a riverside area, initially considered using scaffolding over the river to accommodate various construction phases. As the managing authority, the New Construction Office incorporated the most rigorous safety standards into the turnkey project. Genyeh Engineering Consultant Co Ltd., responsible for project management, evaluated the environmental conditions and required bidders to propose safety strategies for beam dismantling and hoisting, traffic management during construction, excavation support, utility detection, and BIM conflict analysis, ensuring robust safety measures from the very beginning. CECI Nova Technology Co., Ltd., responsible for the design, conducted a detailed risk analysis of the project using a high-risk matrix to tackle potential hazards such as falls, water exposure, heat risks, and confined spaces. They recommended that the initial scaffolding method be changed to a cantilever method, significantly minimizing the scale of temporary structures and waterside operations. The company also devised proper construction guidelines, drawings, and budgets, equipping contractors with ample resources to deliver their professional expertise effectively. Hung Chen-ju, Head of the Central Public Works Office of the Public Works Division, noted that Chun Yuan Construction Co., Ltd. led the on-site execution planning, working closely with Genyeh Engineering Consultant Co Ltd., which also acted as the supervisory unit. The project prioritized risk mitigation by transforming the traditional cantilever launching method into an innovative technique that integrated truss beam work vehicles with chainsaw cutting, creating a novel application for existing tools! This new method centered on hazard reduction through mechanization, placing workers in safe environments to operate machinery for cutting and removing concrete structures and hoisting steel components. By eliminating fall risks entirely, the project supported the Ministry of Labor’s 2024 Fall Prevention campaign. Additionally, it addressed potential dangers from structural collapses, traffic impacts, and vibrations, while implementing robust measures to control and mitigate residual risks, lowering overall hazard levels. Hung Chen-ju concluded by noting that the construction team worked responsibly and tirelessly throughout the project, excelling in areas such as professional personnel training, mechanized construction, prefabrication of components, integration of disaster-mitigation technologies, standardization of design, and visualized safety. These efforts ensured comprehensive safety, meeting the team’s original aspirations for the project and achieving robust risk management and safety goals. Emerging as a standout among many teams committed to construction safety, the New Construction Office expressed heartfelt gratitude, reaffirming its dedication to leading the construction team in its mission to strengthen construction safety for Taiwan. The Office aims to provide citizens with more comfortable and well-equipped public facilities.
