DADI WINS THE GOLDEN REWARD OF CHINA STEEL STRUCTURE

DADI WINS THE GOLDEN REWARD OF CHINA STEEL STRUCTURE

China Construction Metal Structure Association (CCMSA) announces in April 2021 the second round of the winning projects in the Fourteenth Session (2020) of Steel Structure Golden Reward of China, featuring the Steel Structure of Jinjiang International Convention and Exhibition Center, constructed by Zhejiang DADI Steel Structure CO., Ltd. under general contract of Longyuan Construction Group CO., Ltd.The Golden Reward of the Steel Structure of China’s Architecture, the highest honor of China’s steel structure industry, is established by China Construction Metal Structure Association under delegation of State Ministry of Housing and Construction. The winning programs, selected once a year, are steel structure projects of various types of buildings undertaken by steel fabricators and erectors in China, which must be conducted within the quality levels deemed outstanding for domestic architecture.Located at Meiling Street, Jinjiang, Fujian Province, one of the starting points of Maritime Silk Road of Ancient Quanzhou, with a steel consumption of 14,200 metric tons, this building covers appr. 103,300 ㎡ and the underground area is appr. 29,400 ㎡, with the aboveground structure dividing into five areas: the exhibition halls, the central ecological hall, the north, and south halls, and the conference center.The roof is a steel truss structure of a large span up to 66 meters with a single facade truss of appr. 101 metric tons. The ceiling of the Central Ecological Hall is single curved with 306m ribbon-like bars. Moreover, this project is the first PPP project undertaken by Long Yuan Construction Group Co., Ltd, and also the first PPP project of venue category constructed in China. As a professional construction company of steel structure, we overcame the difficulties such as the complexity of levers on intersecting joints, thick plates welding and the welding seam, etc. By so far, many auto shows and food shows have been held in this building which is no doubt a brand-new landmark of Jinjiang. As DADI contributing to PPP demonstrative project, the professional abilities and competitive edges are boasted with such a victory. We will consider it as a beginning to keep promoting our principle: “our values are our services to craft a brighter future.”. We will also enhance our construction management and technology innovation and application to provide more and better services for our customers and the society.

Mission Complete: Waterproof Roofing Construction of Guiyang Longdongbao Airport T3 Terminal

Mission Complete: Waterproof Roofing Construction of Guiyang Longdongbao Airport T3 Terminal

Upon our workers’ hard-working, the waterproof roofing construction of Guiyang Longdongbao International Airport T3 Terminal was accomplished as scheduled on March 30. Leaders in charge of the third phase of the expansion and the leadership from DADI attended the ceremony.The project on T3 terminal, covering 90,000 m2, consists of the roofing from the airside and connecting corridors (A zone), terminal building (B zone), and connecting corridor (C zone), including roofing structure, constructional layer, smart skylight, and siphon rainwater system. The total area of paved materials is 658,000 m2 and the steel consumption is 288 metric tons. The smart skylight system, covering 6,000 m2, adopts the electrochromed glass, a high-tech material firstly used in domestic airports, which is able to shield from sunlight and receive natural light in need of the people inside the building. The original three-zone construction plan for totally 320 days was changed to 22-zone for 60 days per zone and the hand-over deadline was postponed to Feb 2021 from April 2020 due to the special geological condition. The tower crane was removed immediately after the completion of civil structure, for the crane had been set up inside the building. Moreover, the large-scale construction or rush work had become difficult because of the work on flight area of the east and the north, and on EPC viaduct of the west.Therefore, it is impossible to finish the construction in 60 days, including the curved roof, the special-shaped steel structure, and the hyperboloid aluminum plate of the outer cornice, with traditional ways making the process neither efficient nor safe and reducing the required precision of high-altitude scattered assembly, to assemble the roof with decentralized parts or to erect the cornice plate by plate after the keels are installed. To solve the problem, the management department adopted innovative BIM technology for modeling primary and secondary purlins and outer cornices, dividing them into various units to be prefabricated and assembled on the ground. The outer cornice was erected and glued on the ground as well, ensuring integral hoisting and one-time forming. Many procedures were conducted on the ground, thus the construction quality and efficiency were enhanced, providing technical support to achieve goals.Since commencement of the roofing construction in March 2020, all the parties involved have been worked so hard against the pandemic and many other difficulties to achieve significant breakthrough with success. On July 15, 2020, the waterproof roofing in GB2-1-1 zone was completed for the first time, and that of the corridor in A zone was accomplished on Nov 30. In the second year, the roofing of the main building was due for completion on March 30, marking the success of achieving the objectives. We will continue to take responsibility on our duty, never forget why we started, and contribute to the airport expansion in 2021. We will also take practical measures to enhance the rapid development of the aviation and economy in Guizhou to celebrate the centenary of the China Communist Party.
