In this assignment, you’ll use the models of your proposed design for the multi-story office building that you created in Modules 6 and 7 as the basis for analysis and performance-based design.
You are expected to develop 2 tasks:
‣
Task 1:Create a 4D simulation of the construction sequence for the elements in your structural model using the Timeliner tool in Navisworks Manage
You can create a 4D simulation of the construction sequence for the structural elements in your structural model using the Timeliner tool in Navisworks Manage. The steps typically include:
Exporting the elements from your structural model to Navisworks as a Navisworks Cache (.nwc) file.
Creating a task timeline in Navisworks or importing one from a project scheduling tool.
Attaching elements to the tasks and simulating the construction process.
‣
Task 2:Create a model-based estimate for the structural elements in your structural model using Autodesk’s cloud-based Assemble software.
You can create a model-based estimate for the structural elements in your structural model using Autodesk’s cloud-based Assemble software. The steps typically include:
Publishing the elements from your structural model to Assemble.
Filtering the model elements in Assemble to decide which should be included or excluded from the estimate.
Choosing the units to be quantified for each type of model element.
Assigning unit costs to each type of model element.
What’s Expected
‣
Task 1: 4D Simulation
Using your structural model from Module 7, create a 4D simulation of the construction sequence for the structural elements in your proposed design using the Timeliner tool in Navisworks Manage.
Export the structural elements from your structural model as a Navisworks Cache (.nwc) file.
Open the Navisworks Manage application. Be careful not to open Navisworks Manage for BIM 360 — a similarly named application — that works with projects saved on the Autodesk Construction Cloud. For our purposes, Navisworks Manage is the one to use to import your locally stored .nwc files.
Create a new Navisworks Manage project and append the .nwc file containing the structural elements.
Create a task schedule for the structural elements. For this visualization, a very simple schedule with 20 to 30 construction tasks would be an appropriate level of detail.
You can create this task schedule using a project-scheduling tool, such as Microsoft Project, or use a simple table created in an Excel or Google Docs spreadsheet.e
This table shows a simple example of a pattern that uses a repeating sequence of erecting columns first, followed by beams, then beam systems (joists), and finally floors at each floor level.
Create tasks in the Timeliner tool, entering a title for each task, an expected start date, and an expected end date.
Attach your model elements to the associated construction tasks in the Timeliner tool task timeline.
Run the Timeliner simulation to verify that the construction process illustrated feels accurate and realistic.
Export your 4D simulation as an AVI file.
Create a 3D view that includes only the elements to be included in your estimate.
Using your structural model from Module 7, create a model-based estimate for the structural elements in your proposed design using Autodesk’s cloud-based Assemble software.
‣
Task 2: Model-Based Estimate
Publish your model elements to Assemble.
Option A: If you’re using a virtual machine and cannot modify the software in your environment, you can import your Revit model from within the Assemble project interface.
Upload your Module 7 structural model to your ACC Docs folder.
Login to Assemble at https://stanford.tryassemble.com
You’ll have access to an Assemble project with a name that looks like Fall 2025 - CEE 120A_220A.
Open this project.
Click the Add/Update Models link to select the model to import from your folder on the ACC Docs site.
Option B: If you can modify the software in your environment, you can publish a view directly to the Assemble project from within Revit.
Install the Assemble plugin for Revit (not available yet for Revit 2025)
Open the Revit model view containing the elements to be published to Assemble.
Open the Assemble > Publish tool and connect to stanford.tryassemble.com.
Choose the Fall 2025 - CEE 120A_220A project.
Turn on the Filter using current view’s visibility/graphics overrides checkbox.
Click Continue:
FIlter the model elements in Assemble to decide which should be included or excluded from the estimate.
Then, for each of the elements to include:
Choose the units to be quantified for each type of model element.
Assign unit costs to each type of model element.
This model-based estimate — created using a very early model of your structural design — will necessarily be very high-level and based on just a few major elements that typically drive the construction cost. For your estimate, you can use these very rough cost guidelines:
Cost of Fabricated Structural Steel: use $1,800 per ton. For our purposes, you can assume structural steel weighs about 490 pounds per cubic foot.
Cost of Wood Beams and Columns: use $120 per linear foot (including installation)
Export a summary report presenting your estimate for the major structural elements in your model.
