Using Navisworks to save time and money with Improved Co-ordination

1. Using Navisworks to save time and money with Improved Co-ordination There are various benefits of Building Information Modeling (BIM); in an MEP department, the majority of the projects are modeled in Revit. Often, other project trades work with Architects who are not designing a building in 3D; in those cases, 2D floor plans are under played, and an appropriate offset is set for each level in Revit. Then, MEP systems can be built in 3D. There are various advantages of this workflow, the most impactful being visualization that comes with modeling in 3D. To summarize, Autodesk Revit delivers a myriad of tools that allow visualizing structure, ductwork, walls, piping, etc. from different user perspectives. Revit can also be leveraged to gain a more realistic view for presentation purposes. While all of these tools and features are useful, they are slow in the case of Revit. This is where Navisworks can help

2. save time and money through quick renders, 4D schedules, clash- detection, and more. Navisworks helps designers show 3D models through reduced constraints & systems; this is what slows down Revit. For example, one can export a view from Revit, to Navisworks, and the result is a visual of every 3D object, minus the large database of parameters and properties that come along with these objects. Not all, but some of that information is taken by Navisworks, which includes object names, classification (door, duct, window, etc.), and the level of detail of development they are modeled on. Navisworks retain material properties for appearance and other information like data for constraints, schedules, etc. is cut out. The result is a 3D model of the building that can be easily and quickly manipulated for visual goals. Once a 3D model is exported to Navisworks, it is possible to any building component, view its modeling details, change the color, transparency, etc. Navisworks uses the selection tree to change the classification of objects at once. For example, designers or modelers can hide an entire floor, or the brightness of the entire structure can be altered. Aside from making images pretty, this is particularly applicable for complex construction where coordination is critical, and it provides an excellent check for designers and contractors. Navisworks Manage includes another tool called “Clash Detective” that identifies collisions in 3D geometry within the model. Due to the simplicity at which one can visualize a model in Navisworks helps identify quick collisions. With both programs running in unison, designers can make modifications to a Revit model as part of the quality control process. Navisworks enables users to select specific objects to look for clashes, for example, structural columns and ducts. Designers and modelers can even identify objects and set tolerances that help in setting certain clearances for equipment. It also helps ensure adequate space is kept for accessibility. By utilizing these visual aids through Navisworks, clients can improve design to save on cost and money with improved coordination. It is important to keep in mind that “A fully coordinated model does not mean clash-free”, a fully coordinated design indicates clashes were detected and

3. reviewed, but not necessarily resolved. For example, a valid penetration that is detected and reviewed is not resolved as a few holes can be drilled onsite for pipes to go through. Navisworks Simulate and Navisworks Manage are two versions of Navisworks that deliver advanced tools for simulation, comprehensive project review for analysis, coordination, and communication. The file types used in Navisworks can be classified as – NWC – cache file that contains all the geometry and setup related information during an export The file is smaller than the original file NWF – also called the Navisworks File Set, it holds all the NWC files that are appended to the project Can be accessed in Navisworks Manage NWD – also called as the Navisworks Document, it holds the complete geometry and other information added in Navisworks like Comments, Timeliner Simulation, saved Viewpoints, and Search Sets. Conclusion Here at iFieldSmart Technologies, we believe in being highly visual. We are also at the forefront of BIM adoption through technology automation to leverage high efficiency. By using and integrating visual technology such as Navisworks and iFBIM, we’re able to improve client designs for visual purposes through quick and easy manipulation, identification, auditing, analysis, and more.
