An involvement is a connection between an involved party (usually a company) and a physical entity such as a building, a module, a complex, or a zone. Each involvement covers one role played by the involved company or individual. A company, for example, can be connected to a building in multiple roles, each of which entails one involvement. Involvements can be projected, historical, or ongoing. A projected involvement is an assigned involvement, where the company has not yet performed its role (as when an architect is selected but has not begun the design). A historical involvement is a one-time action which continues to hold relevance (for example a contractor builds a building once then leaves the project when completed). A continuing involvement is relevant only for its actual time period (e.g. a property manager's relationship with a building).
