P

• Package CoordinationThe coordination of design or construction information across a defined work package and its interfaces with other packages.
• ParameterA named data field used to describe or control a model element, type, or project record. Parameter quality is essential for schedules, model checking, and information exchange.
• Parameter AuditA check that required model parameters are present, correctly named, populated, and formatted.
• Parameter ManagerA tool or function used to create, map, audit, and maintain model parameters across files or projects.
• Parametric ConstraintA rule that controls geometry or relationships using dimensions, formulas, alignments, or locked references.
• Parametric ModelerA model author who builds geometry and data using parameters, rules, constraints, and reusable logic.
• Parametric ModelingA modeling approach where geometry and data are controlled by parameters, formulas, and constraints. Parametric Modeling makes model content adaptable, reusable, and more consistent.
• PhotogrammetryA reality capture method that derives measurements and 3D information from overlapping photographs. Photogrammetry can support Point Cloud creation, site documentation, and progress monitoring.
• PipeworkA network of pipes, fittings, valves, and accessories used to convey fluids or gases. Pipework appears in Plumbing Model, Fire Protection Model, and mechanical systems.
• Plain Language Question PLQA simple business question used to define what information must be captured to support a decision.
• Plumbing ModelA discipline model representing domestic water, sanitary, storm, drainage, gas, or related piping systems. Plumbing Model coordination often uses Pipework, slopes, clearances, and equipment locations.
• Point CloudA large set of measured points representing surfaces and objects in physical space. Point Cloud data is commonly used for Scan-To-BIM, progress checks, and existing-condition documentation.
• Point Cloud ViewerA tool used to navigate, measure, and compare dense scan data against models or survey references.
• Post-Appointment BIM Execution PlanThe agreed BIM Execution Plan developed after appointment and aligned with the contract, team structure, and delivery schedule. It turns proposals into the working information management approach.
• Pre-Appointment BIM Execution PlanA proposed BIM Execution Plan prepared before a party is formally appointed. It demonstrates capability, intended methods, and understanding of the Exchange Information Requirements.
• Precast ConcreteConcrete elements manufactured away from their final installed position and then transported to site. Precast Concrete modeling can include panels, beams, connections, reinforcement, lifting points, and assembly sequencing.
• Preventive MaintenanceMaintenance performed on a planned schedule to reduce failures and extend asset life. Preventive Maintenance can be managed through a Computerized Maintenance Management System using Asset Register data.
• Product Data Template PDTA Data Template focused on product or manufacturer information needed for specification, procurement, or handover.
• Progress TrackingThe comparison of planned progress against actual site status using model, schedule, field, or capture data.
• Project Data ManagerA role responsible for data structure, data quality, reporting, and integration across project systems.
• Project Information Model PIMThe information model developed during design and construction to support project delivery. The Project Information Model can be transformed or filtered into an Asset Information Model at handover.
• Project Information Requirements PIRInformation requirements that support decisions and deliverables during a specific project. They translate organizational needs into project-level information outcomes.
• Project Information StandardA project-specific rule set for naming, classification, model structure, data fields, and exchange behavior.
• Project ParameterA parameter added to categories within a project to store information that is not necessarily built into family definitions. Project Parameter use can support schedules, filters, and project-specific…
• Project TeamThe combined participants working toward the project outcomes, including client-side, design-side, construction-side, and specialist contributors.
• Project TemplateA preconfigured starting file or setup containing standard views, settings, families, parameters, and documentation rules.
• Property DictionaryA controlled vocabulary of property names and meanings used to reduce ambiguity in digital information exchanges.
• Property Set PsetA grouped collection of properties attached to an object or object type. Property Set structures help organize IFC data, asset attributes, and information requirements.
• Proprietary BIMBIM workflows based mainly on native formats, vendor-specific features, or closed data structures. Proprietary BIM may improve tool-specific productivity but can create interoperability challenges.
