  • Data DictionaryA controlled reference for terms, properties, units, and meanings used across information exchanges. A Data Dictionary improves consistency between Information Requirements and delivered data.
  • Data ExchangeThe transfer of model, document, schedule, cost, or asset information between parties or systems. Good Data Exchange depends on clear requirements, formats, validation, and responsibilities.
  • Data Extraction ToolA tool that pulls structured information from models or documents for schedules, reports, audits, or downstream systems.
  • Data Integration MiddlewareA software layer that transforms, routes, and synchronizes data between project or asset systems.
  • Data OwnershipThe assignment of responsibility for creating, approving, maintaining, and correcting a defined set of data.
  • Data StewardshipThe ongoing care of data quality, meaning, accessibility, and governance across systems and project stages.
  • Data TemplateA reusable set of fields, units, and rules that describes what information should be collected for a class of objects.
  • Data ValidationThe checking of model or asset data for completeness, format, values, units, and compliance with requirements. Data Validation supports Information Delivery Specification and Asset Information Model quality.
  • Data Validation ReportA report showing whether submitted data passed completeness, format, naming, classification, or rule checks.
  • Delivery TeamThe group of organizations and people responsible for producing project information and physical works for an appointment.
  • Design AuthorThe person or organization responsible for the technical design intent represented by information deliverables. Design Author responsibility is distinct from simply producing or coordinating a model.
  • Design Option AnalysisThe comparison of alternative design solutions using model-based data such as cost, space, energy, or constructability impacts.
  • Design ReviewA review of design intent, coordination, compliance, and performance using drawings, models, reports, or meetings. Design Review can use Federated Model navigation and issue tracking.
  • Deviation AnalysisThe comparison of captured reality data with intended design or tolerance limits to identify differences.
  • Digital Construction ManagerA role responsible for applying digital methods to construction planning, coordination, site execution, and reporting.
  • Digital Delivery Plan DDPA plan that turns digital strategy into practical actions, deliverables, tools, responsibilities, and review points.
  • Digital Delivery StrategyA high-level plan for how digital methods, models, data, and collaboration platforms will support project delivery.
  • Digital Handover LeadA role that coordinates handover requirements, asset data, model deliverables, and final acceptance activities.
  • Digital SignatureA cryptographic or controlled electronic signature used to show approval, authorship, or integrity of a digital record. Digital Signature use can support governance in Approval Workflow and Information…
  • Digital SnaggingThe capture, assignment, and tracking of defects or incomplete work through a digital field process.
  • Digital ThreadThe connected flow of information across design, construction, handover, and operations so decisions remain traceable.
  • Digital TwinA digital representation of a physical asset that is kept useful through data connections, updates, and operational context. Digital Twin use may combine Asset Information Model, Sensor Data,…
  • Digital Twin ManagerA role that manages the operational digital representation of assets, data connections, performance information, and governance.
  • Digital Twin PlatformA platform that connects asset models with operational data, analytics, visualization, and lifecycle workflows.
  • Discipline BIM LeadA discipline-specific lead who manages BIM delivery quality, model structure, and data requirements for one technical discipline.
  • Discipline ModelA model produced by a specific discipline such as architecture, structure, mechanical, electrical, or civil design.
  • Document Control PlatformA platform for registering, reviewing, issuing, revising, and archiving controlled project information.
  • Document ControllerA role focused on registering, issuing, tracking, and archiving documents and controlled records.
  • Document Management System DMSA system for storing, organizing, searching, and controlling documents. In BIM projects, a Document Management System may be part of or connected to the Common Data Environment.
  • Door ScheduleA structured list of doors and their attributes such as type, size, fire rating, hardware, location, and finish. Door Schedule data is usually driven by Architectural Model parameters.
  • Drone Survey UASThe capture of site imagery or mapping data using unmanned aircraft for monitoring, survey, or progress records.
  • DuctworkA network of ducts and fittings used to distribute or extract air in a building. Ductwork geometry is important for MEP Model coordination and Clash Detection.
  • Duplicate Element CheckA review that finds overlapping or repeated objects that may distort quantities, coordination, or analysis.
