Exchange Model and Exchange Object Concepts for Implementation of National BIM Standards

Abstract

The industry foundation class ͑IFC͒ standard building model schema is a necessary but not sufficient condition for achieving full interoperability between building information modeling ͑BIM͒ tools. Unless each information exchange within construction project workflows has its specific contents and level of detail defined, the breadth and flexibility of the IFC schema leaves room for errors. The national BIM standard approach for resolving the ambiguities of information exchange is based on "use cases," which precisely define the data required in each information exchange between disciplines in engineering workflows. In this paper, we define specific procedures for developing information delivery manuals ͑IDM͒, which capture the use cases and the precise information to be exchanged. We also identify some of the data semantics we found problematic that require workflow specification. We further propose details of the information capture that allow the IDM to serve as a specification for later implementation and testing. The procedures are illustrated using examples from an IDM specification developed for the domain of architectural precast concrete.

Object Interaction Query: A Context Awareness Tool for Evaluating BIM Components’ Interactions

“…Rule--based checking in BIM has been widely studied and developed by, among many others, Charles M. Eastman (Eastman et al, 2009(Eastman et al, , 2010Zhang et al, 2012). In their paper titled Automatic Rule--Based Checking of Building Designs (2009), Eastman et al provide a thorough survey of both the technology and structure of several IFC--based rule--checking efforts.…”

Exploratory Study on BIM-based Information Breakdown Structure for Construction Document Management

“…Lee (2008) checked that it is possible to control construction info through BIM by applying info process to the project of apartments from proposing the process for BIM application in stages of design, building, and maintenance. Eastman et al (2010) suggested a data conversion system for compatibility of figure info between the IFC file system and the US BIM standard system to smooth info sharing through BIM models. Also, Liu and Issa (2012) examined plans for smooth info compatibility between BIM model info and info of the maintenance system so as to apply the BIM model info to the maintenance system for heightening the availability of BIM of the design stage in the maintenance stage.…”

PLM and architectural rehabilitation: a framework to improve collaboration in the early stages of design

“…For example, the National BIM standard approach, well suited to the construction of new buildings, uses groups of experts in AEC to specify use-cases in what they call "Information Delivery Manuals" (IDMs). These IDMs serve as a basis to create specifics import and export translators to facilitate collaboration between design and construction stakeholders (Eastman et al, 2010); -Assisting the redesign of existing buildings, especially to the degree befalling France at time of writing, is less of a concern to BIM than assisting the design of new buildings allowing leeway for redesign later in the lifecycle; -More importantly to us, BIM software is currently incompatible with design approaches placing user involvement at their core such as participatory design, and is therefore of limited interest to user-centered architectural redesign.…”
