Approved Use Matrix
The Approved Use Guide is intended to clearly define what the BIM should be capable of at various points in its development. For example, a LOD 200 BIM can be used to create time scaled, ordered appearance of major activities when used for 4D scheduling.
|Model Content||LOD 100||LOD 200||LOD 300||LOD 400||LOD 500|
|3D Model Based Coordination||Site level coordination||Major large object coordination||General object level coordination||Design certainty coordination||N/A|
|4D Scheduling||Total project construction duration
Phasing of major elements
|Time-scaled, ordered appearance of major activities||Time-scaled, ordered appearance of detailed assemblies||Fabrication and assembly detail including construction means and methods (cranes, man-lifts, shoring, etc.)||N/A|
|Cost Estimating||Conceptual cost allowance Example $/sf of floor area, $/hospital bed, $/parking stall, etc.
Assumptions on future content
|Estimated cost based on measurement of generic element (i.e. generic interior wall)||Estimated cost based on measurement of specific assembly (i.e. specific wall type)||Committed purchase price of specific assembly at buyout||Record costs|
|Program Compliance||Gross departmental areas||Specific room requirements||FF&E, casework, utility connections|
|Sustainable Materials||LEED strategies||Approximate quantities of materials by LEED categories||Precise quantities of materials with percentages of recycled and/or locally purchased materials||Specific manufacturer selections||Purchase documentation|
|Analysis/Simulation||Strategy and performance criteria based on volumes and areas||Conceptual design based on geometry and assumed system types||Approximate simulation based on specific building assemblies and engineered systems||Precise simulation based on specific manufacturer and detailed system components||Commissioning and recording of measured performance|
