BIM Floor Area Analysis

Spatial structure, area allocation, efficiency, and quantity-quality review for the modeled ground-floor storey.

What the numbers say

Data quality panel
Compact checks for the classic BIM floor-area traps: inferred gross area, property-set space quantities, and geometry consistency.
    Room-by-room area table
    Modeled spaces only, with net area, geometry check, and share of the gross storey footprint.
    Space Category Net area Geometry area Δ net vs geometry Share of gross Quantity status Flags
    Room net floor area
    Which modeled space dominates the usable floor plate?
    Gross floor-area breakdown
    How the storey footprint splits across primary room area, circulation, and the residual non-room gap.
    Allocation walk from gross area to primary room area
    A waterfall view showing how the 25.75 m² slab benchmark resolves into modeled net area and then into circulation vs primary space.
    Modeled-space dominance treemap
    Share of modeled net area by space, useful here because only two rooms are carrying nearly the entire floor story.
    Net-to-gross efficiency check
    Heuristic reference only, not a compliance benchmark: values above the high band can indicate compressed wall or service accounting in the model.
