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 named and contain data * All concrete elements must be assigned to a concrete material * All concrete elements must have their construction method assigned * All concrete elements must have their strength class assigned * All concrete materials must have their compressive strength assigned Scenario: All concrete element data must be in a standardised form * 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 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
