To comprehensively showcase the achievements of digital transformation in Shanghai's housing and urban-rural development sector, publicize and promote successful experiences, and identify and cultivate innovative talent, the Municipal Commission of Housing and Urban-Rural Development Management organized the 2024 collection of outstanding digital-transformation cases and the selection and cultivation of innovative talent in Shanghai's housing and urban-rural development sector.Recently, the list of outstanding digital-transformation cases in Shanghai's housing and urban-rural development sector was released, and 10 top digital-transformation cases were selected. Let's take a look at these outstanding cases below.
Top Ten Cases:Large-Model and Digital-Twin-Driven Smart O&M for the Shanghai Library East Branch
Implementing Organization:Shanghai Construction No. 4 Group Co., Ltd.
The Shanghai Library East Branch is another 'readable' urban cultural landmark meticulously built by the No. 4 Group over four years, and is the largest single-structure library in China by floor area. The project has a total floor area of 115,000 square meters, with seven floors above ground and two underground, providing 6,000 seats. It meets the cultural needs of more than 200 lectures and over a thousand academic events of various kinds each year, and can receive up to 4 million reader visits annually. The goal is to build it into a 'smart, composite library for the era of mass reading.'
Shanghai Library East Branch
To achieve this goal, the Shanghai Library East Branch smart O&M project came into being. Relying on large-model and digital-twin technologies, and through the collection, analysis, and utilization of full-lifecycle data of the Shanghai Library East Branch, the project built a smart O&M platform oriented toward multi-terminal applications, realizing functions such as digital-twin-driven smart O&M, large-model-empowered knowledge management, AI-assisted security control, and personalized services and support for the library. It not only improves the library's management and operational efficiency, but also provides readers with a smarter, more convenient, and more personalized service experience.

Innovation Highlights
Efficient Cross-Stage Digital-Twin Model Construction and Management:By developing a variety of digital-twin model construction algorithms, the project solved the problem of converting BIM models from construction to O&M, achieving in-depth application across the building's full lifecycle. Model construction efficiency improved eightfold, entity accuracy reached 92%, and the updatability of the model as well as the fusion and dynamic updating of multi-sensor information were realized.Refined Intelligent Control Technology:In response to the differing comfort needs of various areas of the library, personalized regulation of key parameters of the air-conditioning and fresh-air systems is achieved through a refined 'one room, one strategy' equipment-operation approach.Smart O&M Technology Integrating Large Models and Digital Twins:By combining large-model technology with digital twins, the platform is able to understand and analyze building-operation mechanisms, provide users with real-time building-operation analysis and optimization services, and achieve an intelligent upgrade of O&M management.

Implementation Results
After the Shanghai Library East Branch smart O&M platform was deployed, it directly served 5 million reader visits, achieved real-time monitoring and fault early-warning of building equipment, identified abnormal carbon-emission areas, connected with the book-sorting system, and provided alerts for full book boxes, among other functions. O&M efficiency improved significantly: equipment-fault response time was reduced from the original one hour to about 15 minutes; over the past year, 3,394 maintenance work orders were completed, 124 abnormal energy-consumption alarms were triggered, curtains were automatically controlled about 10,000 times, and book sorting and delivery were monitored about 5 million times; cumulative energy costs were reduced by about 8 million yuan. The project's implementation has driven the development of other O&M businesses. To date, it has been successfully applied in a number of landmark building projects, including Shanghai East Hospital, Shanghai Xinhua Hospital, Jiaxing Pinghu Second Hospital, Shenzhen Nanshan Hospital, Qingdao Jiaozhou Hospital, and the Shanghai Children's Library. |

Our team brings together senior engineers from leading design institutes, former executives of real-estate companies, BIM engineers and prefabrication engineers, delivering integrated design optimization, refined drawing review, BIM consulting with MEP detailing, and prefabricated design services.
Design optimization consulting: Positioned as an extension and complement to the design management of real-estate developers, we focus on consulting and optimization for civil buildings. Across the whole process — or at key stages required by the client — we control the economy, rationality and safety of the design, eliminating unnecessary cost while measurably improving drawing quality, achieving "lower cost, higher efficiency".
BIM consulting: Through digital construction technology we help designers reduce errors and improve quality in the design phase, help contractors save cost and plan high-quality MEP installation in the construction phase, and extend BIM models into facility management for the operation phase — in collaboration with mainstream software vendors.
Prefabricated design consulting: Whole-process design on BIM platforms, using Revit and Tekla for PC detailing. Component geometry and reinforcement are linked parametrically — what you see is what you get. We deliver Industry 4.0-ready drawings with cut-length data for every rebar, and IoT-enabled support for production, storage, transport and installation of PC components.
Our expert team comes from leading design institutes, with deep technical grounding and extensive experience in dual-track design and optimization; its technical capability and control are industry-leading.
