Case Study of Constructability Reasoning in MEP Coordination
暂无分享,去创建一个
Building system coordination is a complicated process that requires the detailed layout and configuration of the various building systems such that it complies with design, construction, and operations criteria. Current practice involves an iterative process of sequentially overlaying transparent 2D drawings of each system over a light table to identify potential conflicts and constraints, which is a time-consuming and error-prone process. Recent research efforts have focused on the development of knowledge-based systems to further assist this coordination process. The objectives of this research were to collect and classify data on constructability knowledge utilized as part of a 3D MEP coordination process during design and construction of a complex research facility. We worked with the project team to develop detailed 3D models of all the building systems in several critical spaces. We identified the design and construction knowledge utilized to coordinate these 3D models and classified this knowledge in a multi-variable knowledge framework. The representational framework, 3D modeling process, and modeling constraints are discussed.
