• Landscape ModelA model representing external spaces, planting, hardscape, terrain, furniture, and landscape systems. Landscape Model information can coordinate with Civil Model and Architectural Model content.
• Laser ScanningA reality capture method that measures dense spatial points using laser-based instruments. Laser Scanning produces Point Cloud data for existing conditions, verification, and As-Built Model workflows.
• Lead Appointed PartyThe appointed party responsible for coordinating information delivery across one or more task teams. It often leads the BIM Execution Plan and consolidates the Master Information Delivery Plan.
• LevelA horizontal reference plane or building storey used to organize model elements vertically. Level information supports views, schedules, coordination, and Location Breakdown Structure.
• Level of Development LODA framework used to describe how developed or reliable model elements are at a given stage. Level of Development is often used with Model Progression Specification and coordination…
• Level of Information Need LOINA way to define the required amount and quality of geometry, information, and documentation for a specific purpose. Level of Information Need helps avoid both under-delivery and unnecessary…
• Life Cycle Assessment LCAA method for assessing environmental impacts across a product or asset life cycle. In AEC, Life Cycle Assessment can use model quantities and material data to compare design…
• Lifecycle DimensionA way of organizing model information around the full asset life cycle from planning through operation and renewal.
• Lighting FixtureA modeled element representing a luminaire or lighting device, often with type, location, electrical, and performance data. Lighting Fixture information supports Electrical Model coordination and schedules.
• Linked DataA data approach that connects information resources through identifiers and explicit relationships. Linked Data can connect BIM, GIS Integration, asset records, and external datasets.
• Linked ModelA separate model file referenced into another model so multiple teams can work independently while coordinating together.
• Loadable FamilyA reusable family definition created or edited separately and loaded into a project. Loadable Family content is common for doors, windows, fixtures, equipment, and custom components.
• Location Breakdown Structure LBSA hierarchical breakdown of a project by physical locations such as building, zone, level, area, or room. Location Breakdown Structure supports planning, quantities, logistics, and progress tracking.
• Logistics ModelingThe modeling of site access, storage, traffic, cranes, hoists, and temporary arrangements to support construction planning.
