Generated from the model — column positions, wall runs, space polygons and grid spacing are read out of the IFC — so a sheet cannot drift from the building it documents. ARCH-D, 5 of 22 registered sheets issued.
Library / Data Center
A 12 MW colocation building: four 3 MW data halls on a raised floor, an electrical yard with N+1 generation, and a chilled-water plant sized for concurrent maintainability.
Generated from the model — column positions, wall runs, space polygons and grid spacing are read out of the IFC — so a sheet cannot drift from the building it documents. ARCH-D, 5 of 22 registered sheets issued.
Share of IfcElement occurrences carrying each part of the record,
read out of the IFC inside the container.
Manufacturer and material fall short of 100% by the same reason: an
IfcOpeningElement is a void and an IfcElementAssembly is a grouping —
neither is a thing anybody manufactures or pours.
