Here we have a wall connection detailthat represents a critical component for theconstruction process that we need to ensure isaccurately communicated to the installers on site.Using straight forward navigation and easy to useselection tools, we simply grab the components weneed, and move them graphically to gain thedesired look and view of the details. This view issaved with our model, and can be added to anydocument or sheet, and annotated to furtherenhance the communication needed to ensure clearunderstanding.Click here to start video1.

We begin in NavisworksManage, and Append a model directly fromAutodesk Revit. Once we have a base model wecan aggregate additional models by appendingmore files. It is important to note that thesemodels do not have to all be from Revit, becauseNavisworks support 60 file types and formats,making it very easy to work with any type of 2Dand 3D information provided.Click here to start videoPage 28

From the Save as Type list, selectNavisworks File Set (*.nwf).Click Save.Exercise 2 – Use Clash Detective to find clashesAn integral part of the coordination using a BIM isthat we can run analysis to determine exactlywhere we have conflicts in our building. ClashDetective is used to run that analysis, and we willPage 31

create and explore several clash tests to analyzethe various systems to find any problems nowinstead of out in the field during construction. Inorder to quickly find the systems we wish to clash,we will start by creating a selections set to collectall the like building components together foranalysis. With the selection sets created, we cannow run the clash detective, and analyze forconflicts. Note that once we have test results, wecan quickly and easily explore the individualclashes, and start to see the areas of conflict we’llneed to manage in the coordination process.Click here to start video1. In Navisworks, open Medical Office – Exercise2.nwf.Note: If a Resolve message is displayed, clickIgnore All.2. On the View tab, Workspace panel, clickWindows. Select Saved Viewpoints.3.

On the Results tab, select a clash to zoom into it.21. Use zoom and pan tools to find a desiredviewpoint of the individual clashes.22. Close the project when finishedExercise 3 – Manage clash views andviewpointsWith our clash tests performed, we can nowmanage the conflicts found through clash groupsand viewpoints. This is beneficial to you and yourPage 33

coordination teams, as we can focus on just theclashes that represent real conflicts, and have areference to come back to throughout the processuntil that conflict is resolved. We can also usecomments to further communicate intent orrequests for the extended team on how to manageor resolve the conflicts.Click here to start video1. In Navisworks, continue from the previousexercise or open Medical Office – Exercise3.nwf.2. In the Clash Detective, under the Struc vMech test, select the Results tab.3. In the Clash list, select Clash 1.In the Items pane, note that the duct ispenetrating a concrete wall.4. Use CTRL wheel to orbit around the clash tothe desired viewpoint. Use the mouse wheelto zoom.5. In the Clash Detective, click Assign to assignresponsibility, and add a comment.6. In the Assign Clash dialog box: For Assign To, enter Mech Sub. For Notes, enter Relocate duct to avoidwall. Click OK.7. To group a set of clashes, in the clash list,select Clash 2.A pipe is interfering with a beam.Page 34

8. In the Items pane, left side, click GroupClashes Involving Item.Several pipes in conflict with the beam aregrouped together.9. Click on the group name to rename it. For thenew group name, enter Pipes in Beam.10. In the Clash Detective, click Assign.11. In the Assign Clash dialog box: For Assign To, enter Mech Sub. For Notes, enter Lower pipes to avoidbeam.Page 35

Click OK.12. On the Review tab, Comments panel, clickView Comments.Page 36

13. In the Clash Detective, click on a clash tozoom to it, and to view the comments in theComments windowClose the project when finished with the exercise.Exercise 4 – Resolve conflicts with SwitchbackAutodesk Navisworks Manage offersinteroperability with Autodesk authoring tools forthe purpose of directly managing clashes found andultimately, taking action to fix them. The switchbackcapability allows us to move from the aggregatedmodel where we found the clash, directly back tothe constructability model, in this case, in AutodeskRevit. With the view opened in Revit, we can takethe appropriate action to resolve the conflict, andthen save the file to update the coordination model.The benefit of using the switchback capability is thatteam members can see exactly what needs to belooked at when resolving a conflict quickly andeasily, greatly reducing the chance for errors oromissions in the coordination process.Click here to start video1. In Revit, on the Add-Ins tab, External panel,click External Tools Navisworks Switchback2015.This allows the Switchback function to operatein Navisworks.2. In Navisworks, open Medical Office – Exercise4.nwf.Page 37

3. In the Clash Detective, on the Results tab,select the 1st flr – duct at beam clash.4. In the Item 2 pane, click Switchback.5. Navisworks switches over to Revit and selectsthe duct for you.6. In Revit, with the duct selected, on theViewCube, select the Southeast isometriccorner.In canvas, you are zoomed to the selectedduct.7. To lower the duct, on the Properties palette,for Offset, enter 11’-1”. Click Apply.8. Save and close the Revit project.9. To update the Navisworks model, inNavisworks, on the Home tab, Project panel,click Refresh.This will reload the current Revit files.10. In the Clash Detective, click Re-run Test.11. Scroll through the clashes to find 1st flr – ductat beam.Page 38

Note that the color has changed and theStatus now reads “Resolved”.12. Click Compact to remove resolved clashesfrom the list.Close the project when finished with the exercise.Exercise 5 – Export clash reportsIn this exercise, we will create clash reports thatallow us to track and communicate the conflictmanagement process with all project stakeholders.These reports will also be a record of the status ofthe coordination process at any given time. Here wecan generate reports for either a selection ofclashes, or the entire clash tests we have in ourmodel currently. We can easily configure theformatting and detail included in the reports, andthen export to standard files formats for viewing,sharing and management.Click here to start video1. In Navisworks, open Medical Office – Exercise5.nwf.2. In the Clash Detective, select the Report tab.3. Under Contents, clear Simulation Dates andSimulation Event.4.

This is where we can further gainvalue from our constructability model and theenhanced documentation with the detail andinformation we added to it earlier to enhance theEstimating process for our building project.This workflow exercise demonstrates how to extractdata from a 2D DWF and PDF file as well as a 3DNavisworks model in order to generate quantitytake offs of elements for the purpose 0f estimation.You will do the following: 2D Quantification using DWF Files 2D Quantification using PDF Files 3D Quantification using BIM Sharing Information with EstimatingPlatformsPage 41

Exercise 1 – 2D Quantification using DWF andPDFWe start the 2D quantification process byleveraging the sheets and construction documentspublished from our Constructability model managedin Revit. Using Navisworks, we can view this 2Dinformation and begin to interact with it togenerate quantities. In order to generate thesequantities, we’ll use a catalog that has our standardquantification items and resources built into it. Atany time we can edit or modify this catalog forproject specific considerations. The important thingto note is that the catalog system allows you andyour firm to leverage a standard set of item names,descriptions and formulas for accurately and quicklygenerating project quantities. We use some simplebut powerful 2D tools to make selections from thedocumentation to quantify our buildingcomponents. We have tools for single line, multiline, area and counts. Note that as you quantifyitems, our workbook is keeping a running tally ofthe critical parameters from the documentation andour catalog, making it very easy to generate andtrack the counts and quantities needed.We will also gain further value from 2D projectinformation provided to us by also using PDF files inour quantification processes. Muck like using DWFs,we can import the PDF versions of our constructiondocuments and perform 2D takeoffs. The importanttakeaway here is the flexibility Navisworks offers forsupporting the 2D information you will have foryour building projects.Click here to start video1.
