First, establish precise parameters. When applying BIM technology to water supply and drainage systems, it is essential to conduct thorough on-site investigations and repeatedly verify critical data at the construction site. This ensures the accuracy and authenticity of the modeling information.
Second, when planning the arrangement of building materials for water supply and drainage in high-rise buildings, it is important not only to establish a dedicated management team but also to utilize BIM technology to create a specialized material database. This database helps relevant personnel quickly understand the types, quantities, specifications, and usage parameters of materials.
Third, when building the pipeline system model using BIM technology, a comprehensive approach is required. Consider pipeline pre-embedding, densely packed pipeline areas, zoning, and simulation of installation processes to ensure the model’s thoroughness and accuracy.
Fourth, collision detection of pipelines must be performed after BIM modeling. Many construction teams using BIM software to create 3D water supply and drainage models skip on-site data verification and testing. Often, the modeling is based on initial data obtained during bidding, but changes on the construction site may have occurred since then. Therefore, the authenticity and accuracy of much of the data need to be confirmed. Unfortunately, to save time, many designers neglect this verification step, increasing the risk of errors in the model parameters. Conducting collision detection after modeling helps identify and correct any mistakes or discrepancies promptly.
