Glossary of Terms
A complete listing of common terminology used in digital delivery is detailed in the linked documents. Key terms are defined below to support information contained on this web page.
Building Information Modeling (BIM): The use of a digital model of a built asset to facilitate design, construction, and operation processes to form a reliable basis for decisions. BIM may also be used as a noun to describe the digital model.
Computer-Aided Design and Drafting (CAD/CADD): A category of computer software that is used to develop designs for a variety of disciplines. CADD software typically uses an object-oriented approach to apply mathematical rules that automate the process of drafting designs. 3D digital design data is a common output of the application of CADD software.
Data Visualization: A thematic display of BIM modeled elements based on property data such as class, materials, and pay items. Tying color, transparency, and display (on/off) to property data allows users to quickly identify and share information about modeled elements.
Digital Twin: Initially conceived of for smart manufacturing, a digital twin is a digital representation of a physical asset that contains a 3D digital model of the physical asset, as well as non-graphical information about the asset such as its properties, functions, evaluative properties, and other analytical context.
Asset Management: A strategic and systematic process for managing assets and programming maintenance and replacement activities. Asset Management Systems are often GIS databases that track the current condition of the assets. The information is updated routinely, when assets are inspected, or when maintenance or construction actions occur.
