The General Principles of Building Information Modeling (BIM) Standards are established to continuously promote the use of BIM technology across the entire project lifecycle. These principles unify the fundamental requirements for BIM application and standardize the creation, preparation, release, implementation, and revision of BIM-related standards. They provide an overview and define the scope of application, outline the framework and core content of the BIM standards system, explain the integration between BIM standards and information systems at various levels, and specify responsibilities for departments involved in preparing, maintaining, and supporting these standards.
The Classification Standards for Building Information Modeling Components and the Coding Standards for Building Information Modeling ensure consistency, standardization, and sustainability in BIM applications. These standards aim to improve the efficiency of BIM technology usage and raise the technical level within enterprises. They clarify how 3D model components are classified and how component data correlates with business information such as cost, scheduling, quality control, and commercial management.
These standards apply to building information model creation and maintenance during design, construction, and project handover phases. They cover general principles, terminology, classification of BIM components, coding rules, and extension regulations. Additionally, they establish guidelines for linking component codes to cost lists and provide classification and coding tables, as well as correspondence tables connecting component codes to key progress milestones, quality inspection items, and enterprise list codes.
The Basic Standard for Building Information Modeling is designed to support BIM application requirements in design management, construction management, and project management throughout project execution. This standard unifies component naming and production methods, defines the smallest modeling units, and consolidates all design parameters.
It also enforces classification-based management of all professional components, enhancing modeling efficiency and reducing construction costs. The standard promotes storing management information—such as design details, cost, quality monitoring, and scheduling—within components to facilitate data integration across BIM models.
The content of the Basic Standard includes general principles, terminology, modeling regulations, component library rules, family library guidelines, and delivery and acceptance protocols.
Specifically, general provisions address the purpose, scope, user roles, and reference standards. Modeling regulations cover modeling planning principles, naming conventions, model organization, and environmental requirements. Component library rules define classification, basic component standards, information content, and maintenance management. Family library guidelines include naming conventions, parameter settings, production processes, acceptance criteria, usage rules, and management practices. Delivery and acceptance protocols specify deliverable formats, content, model compliance, integrity, drawing-model consistency, and acceptance procedures.
The purpose of the Design Application Standards is to guide all design contractors involved in a project to adopt standardized modeling methods, workflows, and technical measures. This ensures compliance with model technical standards and data requirements.
These standards include general principles, preparation of project documentation, naming and color coding for mechanical and electrical systems, modeling specifications, coding and data entry methods or solutions, model validation procedures, and appendices. The modeling specifications detail the processes, modeling details, and any special requirements specific to each design discipline.
The Design Delivery Standards regulate the submission of BIM deliverables from design teams and clarify the requirements for delivering models during the design phase. These standards are formulated based on the Basic Standards for BIM, Classification and Coding Standards for BIM Components, and the Application Standards for BIM Design.
They encompass general provisions, deliverables, and acceptance criteria. Deliverables are categorized into five types: model files, interface files, auxiliary files, report files, and audit files. Acceptance covers the basis, principles, steps, participants, and key review points for approving the deliverables.
Construction Application Standards address the planning, detailing, organization, management, safety, and other BIM-related activities during the construction phase. Serving as a crucial link between construction and operation phases, the Completion Delivery Standards define required deliverables for the completion model in terms of components, information, and data.
They also clarify the procedures for inspection, review, and handover to ensure a smooth transition from construction to facility operation and maintenance.
