MicroMVDs for exchange requirements/Quantity take-off MicroMVD
From Wiki.OSArch
The following MicroMVD vocabulary can be used to ensure that data is present for basic dimensional quantity take-off.
- Concrete material: "Concrete" in IfcMaterial.Category
- Concrete construction method: Pset_ConcreteElementGeneral.ConstructionMethod
- Strength class: Pset_ConcreteElementGeneral.StrengthClass
- Compressive strength: IfcMaterial.Pset_MaterialConcrete.CompressiveStrength
Feature: Quantity take-off In order to cost elements For cost planners All elements need to have dimensional and cost-significant metadata assigned Scenario: All concrete elements are identifiable and contain data * All concrete elements must be assigned to a concrete material * All concrete elements must have their construction method assigned with one of the following values: | Value | | In-situ | | Precast | | {value} | * All concrete elements must have their strength class assigned with one of the following values: | Value | | N | | S | | {value} | * All concrete materials must have their compressive strength assigned with one of the following values: | Value | | 20000000 | | 25000000 | | 32000000 | | 40000000 | | 50000000 | | 65000000 | | 80000000 | | 100000000 | | {value} | Scenario: All blockwork walls are identifiable * All blockwork walls must be assigned to a block material Scenario: All partition walls are identifiable * All partition walls must be assigned to a partition material Scenario: All steel elements are identifiable and contain data * All steel elements must be assigned to a steel material * All steel elements must have a coating assigned with one of the following values: | Architectural | | Fire resistant | | None | * All steel elements must have a grade assigned with one of the following values: | 250 | | 300 | | 350 | | 400 | | 450 | Scenario: All walls must have dimensional quantities * All in-situ concrete walls must have a Length, Height, NetVolume, and GrossSideArea quantity * All precast concrete walls must have a Length, Width, Height, and GrossSideArea quantity * All blockwork walls must have a Length, Width, Height, and GrossSideArea quantity * All partition walls must have a Length, Width, Height, and GrossSideArea quantity * All other walls must have a Length, Width, Height, and GrossSideArea quantity Scenario: All slabs must have dimensional quantities * All in-situ concrete slabs must have a Width, Length, Depth, Perimeter, GrossArea, and GrossVolume quantity * All precast concrete slabs must have a Width, Length, Depth, Perimeter, GrossArea, and GrossVolume quantity * All other slabs must have a GrossArea quantity Scenario: All columns must have dimensional quantities * All concrete columns must have a Length, OuterSurfaceArea, and GrossVolume quantity * All steel columns must have a Length, OuterSurfaceArea, GrossVolume, and GrossWeight quantity * All other columns must have a Length, OuterSurfaceArea, GrossVolume, and GrossWeight quantity Scenario: All beams must have dimensional quantities * All concrete beams must have a Length and GrossVolume quantity * All steel beams must have a Length, OuterSurfaceArea, GrossVolume, and GrossWeight quantity * All other beams must have a Length and GrossVolume quantity Scenario: All foundations must have dimensional quantities * All footings must have a Length, Width, Height, GrossSurfaceArea, and GrossVolume quantity * All piles must have a Length, OuterSurfaceArea, GrossVolume, and GrossWeight quantity Scenario: All other elements must have dimensional quantities * All railings must have a Length quantity * All openings must have a Width, Height, Depth, Area, and Volume quantity * All stair flights must have a Length and GrossVolume quantity * All structural members must have a Length, OuterSurfaceArea, GrossVolume, and GrossWeight quantity * All reinforcement bars must have a Length and Weight quantity * All reinforcement mesh must have a Length, Width, and Weight quantity * All curtain wall panels must have a GrossArea quantity * All windows must have an Area quantity * All duct segments must have a Length, OuterSurfaceArea, and GrossWeight quantity * All pipe segments must have a Length, OuterSurfaceArea, and GrossWeight quantity
