Core Viewpoint - The completion of the steel structure for the R&D building in Beijing Zhongguancun Comprehensive Bonded Zone marks a significant milestone in the project, showcasing advanced construction techniques and a focus on high-tech industry development [1][3][5]. Group 1: Project Overview - The project is located in Haidian District, Beijing, covering an area of 40 hectares, with the building area of the East District project approximately 140,000 square meters [3]. - The steel structure utilizes a total of 32,000 tons of steel and consists of six individual buildings, with the main structure of the R&D building designed in a "U" shape [3][5]. - The construction team divided the project into seven operational units to expedite the construction process, employing a modular construction approach that includes precise prefabrication of core components [3][5]. Group 2: Construction Techniques - To address the challenges of lifting heavy steel structures, the project team implemented a "ground assembly + hydraulic synchronous lifting + high-altitude precise positioning" technique, reducing high-altitude work by 30% [5]. - The use of hydraulic synchronization systems, reaction force systems, and real-time monitoring systems allowed for efficient ground-level operations [5]. Group 3: Strategic Importance - As the first comprehensive bonded zone in the country characterized by "R&D innovation," the project focuses on high-tech fields such as integrated circuits and healthcare [5]. - The construction of a "pilot workshop" will support enterprises in bridging the gap from technology research and development to product implementation, serving as a key engine for regional industrial innovation and upgrading [5]. - The project's completion is expected to significantly contribute to the integrated development of the Zhongguancun Comprehensive Bonded Zone and Haidian District [5].
