00 Level of Development - LOD
Level of Development - LOD is generally defined as follows:
LOD 100 - The equivalent of conceptual design, the LOD 100 model usually consists of overall building massing designed to perform whole building type analysis including volume, building orientation, square foot costs, etc.
相當於概念設計，模型通常包括整體建設集結設計及執行整個建築類型分析所需包括容量、 建設方向、 平方英尺的成本，等等。
LOD 200 - Similar to schematic design or design development, the model would consist of generalized systems including approximate quantities, size, shape, location and orientation. LOD 200 models are typically used for analysis of defined systems and general performance objectives.
類似原理圖設計或設計開發，該模型包括近似的數量、 大小、 形狀、 位置和方向。LOD 200 模型通常用於定義的系統分析及一般性能目標。
LOD 300 - Model elements equivalent to traditional construction documents and shop drawings. LOD 300 models are well suited for estimating as well as contruction coordination for clash detection, scheduling, and visualization. LOD models should include the attributes and parameters defined by the owner in the BIM deliverable standard.
LOD 400 - This level of development is considered to be suitable for fabrication and assembly. This LOD is most likely to be used by specialty trade contractors and fabricators to build and fabricate project components including MEP systems.
這一級別的發展被認為適合於製作和程式集。此級別被認定為工程承建商生成和製造加工包括製作 MEP 系統元件所適用的類型。
LOD 500 - The final level of development represents the project as it has been constructed including as-built conditions. The model is configured to be the central data storage for integration into building maintenance and operations systems. LOD 500 models will include completed parameters and attributes specified in the owners BIM deliverable specification.
模型配置為建築維護和運行參數皆由中央系統存儲。LOD 500 模型包括已完成的參數和業主所需規範中指定的屬性及其 BIM 的最後結果。
