Quantification in Navisworks has now been available for around 18 months and during that time I've shown it to many customers, whilst there are obvious benefits for the estimators and quantity surveyors, the people who seem most excited about the possibilities are not in those teams, why?
A typical Bill of Quantities can take weeks to build, verify and validate, this can be dead time for planners, site managers and buyers who need to make rough estimates in the meantime of quantities needed for purchases, transportation needed for planning and many more tasks on any construction project. Whilst not dismissing the BoQ, as it's an essential document for contractual reasons and verified accurate quantities, Quantification from models can free up essential resources at a key period and empowers many more in the supply chain to make better informed decisions when it is relevant to them. It allows for the extraction of key information from the model and project, a key principle of BIM, which allows you to utilise the model for many purposes.
As with many other parts of the Autodesk portfolio, working with a single tool can solve a business need, working with multiple tools together can solve multiple needs to people who have never seen the need for BIM in their workflows before. These videos demonstrate the first in a series of potential powerful workflows that can help site managers, planners, buyers and more utilising Quantification and various other tools in the Autodesk Construction portfolio.
Remember you can quantify from Revit files, DWFx, DWF and IFC out of the box, a PDF reader is available through the App Exchange, and you can easily map more quantities by using Takeoff Mapping on the Item Catalog Toolbar.
