49. Assembly Model
Stable section ID: S05-CON-007-SECTION-50 · 59 content blocks
An Assembly is a coordinated collection of Components arranged to perform one or more combined engineering functions.
An Assembly may be:
structural frame;
wall panel;
floor panel;
roof panel;
façade panel;
utility rack;
service core;
kitchen panel;
bathroom panel;
equipment module;
temporary construction assembly.
Each Assembly shall define:
Assembly Type and Instance IDs;
constituent Components;
internal Connections;
external Interfaces;
assembly coordinate system;
reference geometry;
mass and center of gravity;
provided capabilities;
required capabilities;
internal dependencies;
manufacturing state;
transportation state;
installation state;
inspection requirements.
Example:
assembly Wall_Panel_WP01 : ExteriorWallPanel {
id: "s05:assembly:wall-panel-wp01";
coordinates: @WP01_Local_CS;
- contains: [
- @Stud_Frame_WP01,
- @Exterior_Sheathing_WP01,
- @Insulation_WP01,
- @Air_Barrier_WP01,
- @Interior_Finish_WP01
];
- internal_connections: [
- @WP01_Frame_Sheathing_Connection,
- @WP01_Insulation_Retention
];
- external_interfaces: [
- @WP01_Base_Interface,
- @WP01_Top_Interface,
- @WP01_Left_Interface,
- @WP01_Right_Interface
];
}
Composition shall not erase the identities of critical subcomponents.
An Assembly may be represented as one transportable or installable unit while retaining detailed internal structure for manufacturing and maintenance.
BDL shall distinguish between:
logical Assembly;
factory Assembly;
transportation unit;
site-installed Assembly;
functional Assembly.
Changes to a subcomponent shall trigger validation of Assembly-level mass, geometry, capabilities, Interfaces, and certification.
