The quality control team comprises three main roles: the project BIM manager, the project BIM leader, and BIM leaders from various disciplines. This team oversees the overall planning of the entire project design process, establishes a project schedule, and coordinates other related tasks. They review and verify the BIM project design schemes, standards, and deliverables. By setting clear norms and standards, the team ensures that project members work efficiently and in an organized manner throughout the design process, achieving unified goals, clear responsibilities, and consistent standards. The responsibilities of each quality control team member are outlined as follows:
(1) The project BIM manager is primarily responsible for leading quality meetings, providing essential training and guidance to the design team regarding model quality control, supervising the preparation work for the BIM design project, and reviewing whether the models comply with specifications, standards, and project requirements.
(2) The BIM project leader oversees the quality requirements and reviews of various professional models within their section. They lead quality-focused meetings, review models submitted by each discipline, and ensure that models in the detailed design phase meet the requirements set by the construction unit and the owner.
(3) BIM leaders from each discipline attend quality meetings led by the project BIM leader. They are responsible for reviewing the quality of their professional models and collaborating with other disciplines to review interface models required for design coordination.
Ensuring high-quality model creation requires not only supervision and review by the quality control team but also thorough self-examination by professional model designers. Specific personnel are assigned to quality control for each model, requiring comprehensive reviews of design results after each stage of the design process. The quality inspection of models focuses on four key aspects:
(1) Visual inspection: By navigating through or isolating components in 3D, ensure that all model components are complete, error-free, and accurately represent the design intent.
(2) Clash detection: Use relevant software or plugins to detect clashes within the model, identifying both soft and hard conflicts between building elements.
(3) Standards compliance: Verify that the design results adhere to BIM modeling standards, CAD drawing standards (including font, size, line type, elevation, layer, etc.), and model accuracy requirements.
(4) Model integrity check: Define clear quality control procedures to ensure the project’s equipment database contains no undefined, incorrect, or duplicate elements. Establish reporting protocols for non-compliant elements to facilitate timely corrective actions.
Once the design results pass approval, the corresponding model application for that stage will proceed, serving as the foundation for the next phase of design work and guiding design principles. If the review fails, the design will be revised and optimized based on the identified issues until it meets approval standards.
