Revit 2020 & Visual Studio 2017: required to compile changes into the plugin.Visual Code: Visual Code (Windows or MacOS).BIM 360 Cost Management: Create BIM 360 project, activate Cost Management module, setup project to create Budget Code Template for Cost Management according to the guide.BIM 360 Account: must be an Account Admin to add the app custom integration, or invited by an admin of a BIM 360 Account.Forge Account: Learn how to create a Forge Account, activate subscription and create an app at this tutorial.Create the Web App to call the workitem.Or you can use Postman to do that according to this tutorial and repo Create your App, upload the AppBundle, define your Activity, you can simply use the **Configure** button in the Web Application to create the Appbundle & Activity.Create a Revit Plugin to be used within AppBundle of Design Automation for Revit.The sample also provides the ability to import the generated budgets directly into BIM 360 Cost Management module, and synchronize the Unit Price for each element between Cost module and Price Book database. The suggested scheme of workflow for the design and quantity takeoff for the architectural and structural models of the building proved that consumed time was at least halved and, in some instances, quartered.This sample demonstrates extracting quantity information of Revit element directly from model under BIM 360 using design automation service, and calculate the budget for each element based on the quantity and price which is stored in database. On the other hand, designing the model and extracting its quantities following the proposed solutions proved a 0.0% deviation from real values. In case where the suggested solutions were ignored, a deviation of (1–33)% in Revit quantities and (1–247)% in Navisworks was observed.

The given solutions were then tested on a bigger scale by designing and extracting the quantities of a multi-story residential building. The methods were then compared in terms of accuracy, time efficiency, and skill level of the designer/surveyor. The study covered 11 models and 27 cases, taking into account various assemblies of building elements and different methods to design these assemblies. The steps taken to minimize the time consumed during the design and takeoff processes were also included in this research. In the scope of this paper, BIM-based quantity takeoff feature was studied in Autodesk Revit and Autodesk Navisworks Manage to give design and takeoff solutions for engineers and surveyors to extract the quantities of materials without a deviation from real values.
