BIM technology is applied throughout the entire lifecycle of a building, from the early planning and design stages to construction, operation, and maintenance. It also extends horizontally across all aspects of architecture and project management.
① Pre-Planning Stage
During the initial project planning phase, a project status model is created to guide conceptual design based on requirements like plot ratio and green space ratio, resulting in a preliminary BIM model. This model allows the use of specialized analysis software to assess environmental impacts, including sunlight, wind, thermal conditions, and sound environment.
When finalizing the design scheme, the BIM model enables quick extraction of construction quantities to estimate project costs. It also facilitates comparison between different design options by weighing their cost advantages and disadvantages, providing crucial insights for informed decision-making.
② Design Phase
The traditional 2D design approach has been replaced by 3D modeling, allowing designs to be visually presented to clients and reviewers for better understanding. This method supports feasibility analysis, significantly reducing the time required for decision-making.
BIM technology enables multidisciplinary collaboration on a single model, eliminating inconsistencies between plans, elevations, sections, and various professional drawings that were common in earlier design methods. The detailed building component data within BIM models also supports performance analyses—such as daylight, sunlight, and ventilation studies—using specialized software.
③ Construction Phase
In the pre-construction planning phase, BIM is used to model temporary structures, simulate office and living area layouts, select tower cranes, plan construction roads, and arrange workshops and machinery. This 3D visualization helps avoid planning oversights and clearly presents the construction scheme.
Before reviewing drawings, BIM models for architecture, structure, and equipment installation are created to detect errors, omissions, clashes, and deficiencies. Identified issues are promptly documented and resolved prior to construction, preventing delays caused by design changes on site.
Construction simulation through BIM enhances production management by linking models with the construction schedule to perform 4D simulations. This optimizes the division and sequencing of construction phases, improving workflow efficiency. Integrating BIM with project information such as schedule, cost, quality, safety, and materials allows for precise querying of quantities and generating cutting lists, supporting lean project management and optimized resource allocation.
BIM transforms technical safety disclosures from complex texts into vivid simulation animations. For complex nodes and high-risk construction plans, BIM models enable clear visual presentations or specialized animations to improve understanding.
Measurement and layout accuracy are enhanced using BIM, especially for challenging projects like hyperbolic curtain walls or steel structures. BIM models provide precise 3D spatial coordinates for components and positioning points, boosting efficiency and accuracy in installation.
④ Operation Phase
After construction completion, the contractor delivers the finalized BIM model to the owner. The operation and maintenance team then refines the model and establishes a management system based on it. By integrating equipment data, construction records, and building component information with the BIM model, this system leverages spatial positioning and data tracking to develop effective operation, management, and maintenance plans, reducing unexpected issues during building use.
