MPS Terms and Definitions

The Model Progression Specification introduces very specific nomenclature.  But it is on this rigid foundation that your virtual construction project will be built.  By assembling Level of Detail, stages, building element categories, aspects and their classes, along with primitives, we start to form a matrix into which your project neatly falls.


Building Elements Categories are defined by Uniformat classification structure.  Aspects are types of downstream information we would like to derive from our project, such as the schedule and estimate, as well as energy calculations.  The Stages are numbered instead of traditional phases (such as 80% CD) because we believe there will be many more model iterations.  The Level of Detail is a definition of the overall building element completeness (geometry, scheduling information, and estimating data); whereas Classes further delineate the information richness in an Aspect.


The Virtual Construction Toolkit contains your element Primitives, along with the corresponding task data and estimating data from the 5D Library.  The Toolkit holds these model elements, estimating database information, and a task list for scheduling.  And users can simply drag and drop content from the Toolkit into the new project.  Because all the naming conventions are consistent, the virtual construction plan starts to come together very quickly.
