Video Summary

In this video, David Lockery, Business Development Manager at AllPlan, and Frank Holtz, Senior Technical Consultant at AllPlan, present a digital estimation workflow for precast building projects. They discuss the challenges that estimators face in the current workflow and how a model-based approach can help overcome these challenges. David explains that the traditional workflow involves manually converting EOR documentation into costing data using tools like Excel. However, this process is time-consuming and leaves little room for big picture thinking and risk assessment. By adopting a model-based estimating workflow, estimators can quickly and intuitively estimate projects by directly tracing the model and automating quantities, details, weights, volumes, and other necessary information. This reduces the time required to create accurate estimates and allows estimators to focus more on the big picture and potential risks. The presenters demonstrate the workflow by creating a model of a parking structure and placing various elements such as columns, beams, walls, windows, stairs, slabs, and double T's. They explain how the model can be used for detailed reports, labels, and visualizations. They also mention that the model can be further developed for detailing and production purposes. The video concludes with a Q&A session where the presenters answer questions about the software's compatibility with Revit, custom element shapes, and the usage of the Revit model in the workflow.
