BIM for Construction Industry Workflow

This Workshop will cover recommended practices for using BIM in Construction and its associated workflows. Several workflows will be highlighted, including Constructability Modeling, Multidiscipline Coordination, Quantification and Field Layout. These workflows will highlight the capabilities of the Autodesk BIM Solutions for Construction, as well as Autodesk BIM360 cloud-based offerings and how they benefit a wide range of professionals in the Construction industry.

Constructability Modeling In this lesson, we will explore the tools and capabilities you can use to add the construction detail to your design intent models. We will focus on how to consume 2D information, use it to build our 3D models, and then how to add or configure a model for construction detail. In the following exercises, you will:

Convert 2D information into a 3D model

Add construction information to the model

Configure the model for preconstruction activities

Create and manage assemblies

Create detailed exploded views

Exercise 1 – Convert 2D Information into a 3D Model

A typical deliverable from our design teams today is 2D paper or digital construction documents. It can be a challenge to use this 2D information to build the models needed to gain the maximum value from BIM in our preconstruction processes. Here we will look at specific tools in Autodesk Revit for consuming this information easily and accurately.

Open Video- Exercise One 1. In Revit, open New Project.rvt. 2. In the Project Browser, verify the Ground

Floor view is the active view. The current view will be Bold. Double-click the view to make it current.

3. To link a CAD file of the Ground Floor plan, on the Insert tab, Link panel, click Link CAD.

Exercise 3 – Configure the Model for Preconstruction Activities

We further enhance our BIM for construction processes by configuring the building components to better suit the construction intent for our project. We start by dividing larger building components into the pieces or sections needed to suit construction practices. This is important because most design intent models do not take construction practices into account when they are created. With these division tools, we can take a concrete wall, divide it into the sections needed to represent individual pours, and add critical detail to the sections like connection details or conduit chases.

Open Video Exercise Three

1. In Revit, open Medical Office – Architectural – Exercise 3.rvt.

2. Verify that the 3D View - Roof Construction view is the current view.

the roof independently.

10. On the Properties palette, from the Parts Visibility list, select Show Original. Click Apply. The original roof is displayed.


Exercise 4 – Create and Manage Assemblies Once all of our building components are divided and the construction detail needed is added, we can use assemblies to pull components together as necessary to best represent our construction practices again. Here we will take several building components that have been modeled separately and combine them into an assembly. The assembly allows us to document, add even more detail, and manage these components easily.

33. Drag the Detail View: Detail Section B view

from the Project Browser onto the sheet.


Exercise 5 – Create Exploded Views The last type of construction detail we can add to our BIM is to take specific building components or critical elements, and create exploded views of the objects to create enhanced documentation and better communicate intent for our project

stakeholders. Here we have a wall connection detail that represents a critical component for the construction process that we need to ensure is accurately communicated to the installers on site. Using straight forward navigation and easy to use selection tools, we simply grab the components we need, and move them graphically to gain the desired look and view of the details. This view is saved with our model, and can be added to any document or sheet, and annotated to further enhance the communication needed to ensure clear understanding.
