Establish a perfect BIM management and standard system, while supporting software development and engineering application, including basic standards, execution standards, data standards and management standards, to realize the standardization of BIM application in urban rail transit projects.

Modeling Base Management System includes a platform side and a plug-in side, which enables unified management of building blocks, components, and product families, and releases and applies them on a project-by-project basis, with suppliers being able to upload and update their products:

1. The component library supports user management, family list publishing based on project dimensions;

2. Associated component-level model unit data templates to support data-model separation;

3. It has gone through multiple version iterations and basically satisfies the use of each component family of the project;

4. The component library provides 2 dimensions of component categorization: professional classification and functional classification, which enables you to find design resources clearly and quickly;

5. Users automate design and reduce modeling costs by selecting multiple components and applying them to the model;

6. The product library supports browsing by specialty, category and supplier; it supports uploading and downloading and updating maintenance of product families;

7. Supports flexible replacement of code indexes and product family objects, which significantly improves the rapid conversion of design models to construction models.

8. The self-developed "Co-Design" BIM data unification service, based on design tools, enables in-house and out-of-house designers to carry out off-site design and multi-disciplinary design on a single model file.

9. It is divided into two parts: the main functions of the platform side include homepage, project group management, directory management, etc.; the main functions of the client side include project browsing, model downloading, synchronizing models, clearing cache, uploading models, etc. Online management of processes, including BIM design process, BIM countersigning process and so on. It can realize online submission, online review and online reply to comments, and the BIM countersigning process can inherit the corresponding BIM design process information to avoid duplication of work and improve efficiency. By combining process management with time plan management, online progress plan control can be realized. Statistical analysis of data generated in the process, mainly including: statistical analysis of model data, statistical analysis of quality data, statistical analysis of personnel data, etc. You can statistically analyze the process status of the model (design in progress, completion of the design, countersigning in progress, completion of the countersigning), and the quality data of the process (the number of questions posed, the number of questions that have been replied to, etc.).
