how to get autodesk quantity takeoff to work properly

Hence, this study examines the BIM-based coordination literature published from 2006 to 2020 through bibliometric literature searching, scientific mapping, and in-depth critical analysis to fill the research gap. Recently, there have been numerous studies investigating BIM-based coordination however, no explicit attempt has been made to investigate the current status of relevant research and determine the future directions. Moreover, by conducting a statistical analysis and examining a case study, this paper verifies the accuracy and efficiency of quantity takeoff attained from the proposed BQTCM method and QTCMP.Įnhancing coordination between stakeholders is a critical function of Building Information Modeling (BIM). This paper proposes a BIM-based quantity takeoff code mapping (BQTCM) method to solve the above issue, and develops a quantity takeoff code mapping plug-in (QTCMP) on a BIM modeling software based on the proposed BQTCM method to obtain an accurate bill of quantities directly and efficiently.

Specific construction classification systems embedded in mainstream modeling software for building information modeling (BIM) make it difficult for countries adopting different systems to calculate quantity directly. Theoretically, quantity can be automatically calculated from building information model more quickly and reliably by extracting geometric data and semantic attributes of building elements. So how do I calculate how many linear feet of 6-inch PVC that I have? All I need to do now is on the Analyze tab, click the Takeoff button, from here I can do a Summary or a Detailed report type.Manual quantity takeoff using two-dimensional (2D) drawings and personal knowledge is error-prone and time-consuming. I've also gone in and created some pipes, some 6-inch PVC pipes, and you can see them drawn and labeled here. So if I go to the Settings tab, right-click Water-Residential, we'll see that my 6-inch and 8-inch PVC have a Pay Item assigned to them. Specifically, the incidental construction section where we've gone into water systems and assigned some of these water sizes, these line items, to parts in the parts list. Now just to review, we've gone into QTO Manager, and I'll find that on the Analyze tab, QTO Manager, and we've loaded up a Pay Item file and a Categorization file, and that's what has populated the QTO Manager with all of this information. Once you have pay items assigned to your pressure network, how do you figure out the actual quantities? Let's see how this is done.
