Congratulations! Dadi Steel Structure Wins Third Prize in the 2020 Shanghai Municipal Steel Structure Industry BIM Technology Competition.
Recently, the Shanghai Metal Structure Industry Association announced the winners of the 2020 Shanghai Steel Structure Industry BIM Technology Competition, with Zhejiang Dadi Steel Structure Co., Ltd.’s entry, “Flowers of the Garden Expo Park under ‘Urban Dual Restoration’,” securing third place in the competition.
This competition attracted numerous large construction firms from the industry, which showcased their BIM application achievements over recent years. Following careful evaluation by a panel of experts, three first-prize winners, six second-prize winners, twelve third-prize winners, and seven excellence award recipients were selected.
The competition is designed to implement the relevant requirements set forth in the State Council’s “Guiding Opinions on Improving the Quality Assurance System and Enhancing the Quality of Construction Projects” (Document No. [2019]92 of the General Office of the State Council) and to accelerate the development of new infrastructure, thereby promoting the integrated application of technologies such as Building Information Modeling (BIM), big data, mobile internet, cloud computing, the Internet of Things, and artificial intelligence throughout the entire lifecycle—from design and construction to operation and maintenance—and elevating the level of digital construction in engineering projects.
This entry is presented across five key areas: project overview, 3D layout planning, Tekla application, MEP integration, and construction management.
Jiangsu Garden Expo Park is located in Tangshan Subdistrict, Jiangning District, Nanjing. Built on the site of a former abandoned mining area, the project embodies the philosophy that “lucid waters and lush mountains are invaluable assets,” serving as a model for ecological restoration and urban regeneration. It is poised to become “Nanjing’s garden that blooms forever,” providing additional exemplars for the “dual urban renewal” initiative across the Yangtze River Delta metropolitan region.
Using BIM construction planning software, a three-dimensional site model is created, enabling comprehensive site master planning and full-process virtual animation simulation of construction to dynamically visualize key construction phases. Additionally, MEP piping and pipeline modeling is conducted to perform clash detection and optimize design solutions.
During construction management, Tekla Structures is leveraged to accurately generate layout drawings, component drawings, and detail drawings; intelligently produce various material takeoffs; and precisely extract component coordinates and centroids, thereby providing reliable data and drawings for material estimation and procurement, component fabrication, and on-site installation. Moreover, through functions such as design model input/output and analysis, seamless collaboration with other BIM software is achieved.
The primary challenges of this project lie in the integration of the steel roof structure with the timber structure, as well as the coordination between the two rooftop flowering columns and the upper floral-crown steel and membrane structures. Given that the steel roof, flowering columns, and floral crown all feature complex spatial hyperbolic forms, the project places stringent demands on detailed modeling and drawing production, shop fabrication, component transportation, and high-altitude on-site installation.
Project Application BIM technology is used to perform three-dimensional modeling and layout of structural components, enabling curved surface modeling and parametric control. Coordinate point data are extracted from the 3D model to guide the erection of steel structure assembly jigs and fixtures, thereby ensuring component fabrication accuracy. Furthermore, the 3D model is employed to simulate construction processes, optimize construction sequences, and support technical briefings, enabling field personnel to efficiently and accurately comprehend complex structural connections.
As The development and practical application of BIM technology, B IM It will deliver greater efficiency throughout the project’s entire lifecycle, from planning and design development to construction and delivery, as well as operation and maintenance. This project is one of the company’s recent This represents a comprehensive showcase of BIM applications. Moving forward, the company will continue to expand both the scope and depth of BIM technology deployment in project management, leveraging BIM as a key enabler for enhancing the precision and digitalization of project management. Winning this competition is a recognition of the company’s Building Information Modeling A test of the application of our achievements, with the hope of leveraging this opportunity to lead the company. BIM technology application has reached a new level!
