The MPS is a language that owners, designers, and builders can use to define every element and task in the building construction process. It serves as a coordination point for information about the building, what is being modeled, and to what level of detail it is being modeled, estimated, and scheduled. It provides the efficient framework for the project stakeholders – a written checklist that matures from a very schematic level of detail to a high level of detail in terms of 3D geometry, cost, and time.
