Shanghai Municipal Commission of Housing and Urban-Rural Development | BIM Review System Comprehensively Upgraded; Intelligent Assisted Review with 2D-3D Linkage for IFC-Format BIM Models and Construction Drawings, Effective June 15
WeChat Sync · Xiaowei · 2025-06-06
To address the problems in Shanghai’s BIM intelligent-assisted review pilot regarding data standards, drawing-model consistency, and review rules, the Municipal Commission of Housing and Urban-Rural Development has comprehensively upgraded the BIM intelligent-assisted review subsystem of the Shanghai Engineering Construction Project Approval Management System (hereinafter the “Municipal Engineering Approval System”) (hereinafter the “BIM Review System”), which will be put into use from June 15, 2025.
[Applicable Projects]
This applies to newly built, renovated, and expanded building construction projects in the city that implement BIM technology application.
[Review Method]
Conduct 2D- and 3D-linked intelligent-assisted review on the design files of the architecture, structural, water supply and drainage, HVAC, and electrical disciplines, such as IFC-format BIM models, electronic construction drawings, and structural calculation reports.
[Review Content]
1. Key mandatory provisions for architecture, structure, and M&E;
2. Structural input/output indicators, reinforcement, and loads;
3. Consistency checks between architectural (structural) drawings, models, and (calculations), as well as model quality checks.
[Materials to Be Delivered]
In accordance with the “Shanghai Municipal Building Construction Drawing Information Model (BIM) Delivery Requirements” (see “Attachment Downloads”), carry out BIM modeling and construction drawing design, export model files in “*.ifc” format and the structural calculation review-and-check data package, and simultaneously complete the construction drawing design files.
[Specific Filing and Processing Procedures]
1. Preparation.The design firm uses the Municipal Engineering Approval System client software (v2.0), and completes, in sequence, information filing, preparation of the design description, and import of files such as construction drawings, models, and the structural calculation review-and-check data package. (Client software download: Shanghai “One-Network Unified Handling” — Government Services — Engineering Construction Project Approval Management System https://gcls.sh.gov.cn, then enter “Model-Assisted Review” in the “Download Zone”)
2. Pre-check.Complete the model quality check, the “drawing-model consistency” check, the structural discipline pre-check, and the drawing seal and signature pre-check.
3. Submission.After the project owner initiates an application for construction drawing design file review or parallel approval of the construction permit on the Municipal Engineering Approval System and confirms the drawings uploaded by the design firm, the design firm uses the client software to push the data and files with one click to the Municipal Engineering Approval System and the web portal of the BIM Review System, for conducting online 2D and 3D review. The project owner submits after review.
4. Model-assisted review (2D and 3D in sync).The BIM Review System launches the intelligent review and generates the review results. The construction drawing review agency verifies the intelligent review results and returns revision comments to the design firm. After the design firm completes the revisions and passes all reviews, the construction drawing review agency issues online a construction drawing design file review certificate of compliance or an inspection opinion.
(The above Steps 1-2 can be completed in advance during the design process, without waiting until the online application; Steps 3-4 are online operations.)
[Relevant Requirements]
Project owner: Secure the relevant funding and organize the design and other entities to carry out BIM design, ensuring compliance with the review requirements.
Design firm: Adopt BIM forward design and drawing output from BIM models, or strengthen the collaboration between BIM design and 2D design, to ensure drawing-model consistency.
Drawing review agency: Make full use of the system to carry out construction drawing design file review and BIM-assisted review work.
Municipal construction administration department: Publish consulting service hotlines by telephone and online, promptly resolve problems encountered by enterprises during operation, and continuously improve system functions and user experience.
Municipal and district construction administration departments and specific-area administrative committees: Intensify training and publicity for intelligent-assisted review, establish rapid consulting service channels for projects under their jurisdiction, strengthen management of the implementation process, and ensure that the work proceeds in an orderly manner.

Zhuwei Architectural Technology is a new-type technical services company specializing in integrated design optimization, BIM consulting and prefabricated construction design consulting. 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.
