5D quantities
BIM quantities & 5D: measurable scope and cost change
Reconcile a bounded takeoff and track the effect of a model revision on a cost plan.
What you will be able to do
Reconcile a bounded takeoff and track the effect of a model revision on a cost plan.
Explore the course curriculum
Open each section to explore the planned learning activities.
Define the measurement
- State included elements, units and deduction rules
- Separate modeled, inferred and manually measured quantities
Build a reliable takeoff
- Map classifications and avoid duplicate linked elements
- Reconcile sample quantities with an independent calculation
Connect quantities to cost
- Attach dated training rates and document inclusions
- Separate base cost, allowances and uncertainty
Control revisions
- Identify added, removed and changed scope by stable IDs
- Explain quantity and rate effects separately in a change report
