Streamlining the connection between real-world layout data and the 3D model

Streamlining the connection between real-world layout data and the 3D model

Most layout processes have connections to 3D models on larger construction projects. However, often this process is time-consuming and fragmented because of data exchange barriers between the system that conveys and captures real-world layout data, and the 3D modeling software. To help address this issue, Autodesk is pleased to announce the launch of the new Autodesk® BIM 360™ Layout app and the companion layout functionality within Autodesk®BIM 360™ Glue® web service.

The new BIM 360 Layout app for iOS takes advantage of a recent partnership with the folks at Topcon and their LN-100 Robotic Instrument for laser-based positioning on the job site. By connecting to the iPad, the LN-100 offers a purpose-built hardware solution perfectly tailored to the demands of General Contractors and MEP contractors alike. The BIM 360 Layout app with connection to the BIM 360 Glue web service challenges modern layout practices being utilized by contractors today. BIM 360 Layout removes common data exchange barriers and provides a seamless connection between the real-time coordinated model and the process of laying-out and staking points in the field. As a result, significantly improved rigor can now be placed on managing and leveraging the up-to-date, coordinated information by the entire project team for construction layout.

Here’s how the process works. First, the design model with field points created in the Autodesk Point Layout plugin are imported into the BIM 360 Glue web service.* Then, point sets can be shared to project field crew(s) via an email link---that when opened on an iPad, launches the BIM 360 Layout app with the assigned point sets ready to be laid-out. Once the field points have been staked, verified or new points collected (all of which can be done while working offline), the field crew can sync the information back to the BIM 360 Glue web service once connected to the internet. The collected points can then be imported from BIM 360 Glue to Autodesk Revit via the Autodesk Point Layout plugin. Within Revit, a deviation analysis can be performed to assess if completed work by an MEP contractor is within the appropriate tolerance and not in conflict with components in the building model.

New packaging, and intuitive user interface increase ease of use

Along with the introduction of BIM 360 Layout, our recent packaging change of providing Autodesk®Navisworks® Manage and Autodesk® Point Layout client access to any Project-based or Enterprise BIM 360 purchasing company has made it even easier for contractors to create points in the design model and then provide to field crews for layout.
Walking to a point represented in the app’s digital model on the iPad is also user intuitive. The BIM 360 Layout app features audible alerts that get louder and faster as proximity to the selected point increases as well as a visual “bulls-eye” marker that changes from red to green when the user is within staking tolerance. (In addition, users can switch to plan view mode for those that would rather view in 2D!)

Faster, easier system set-up

For those on a layout crew, you know the challenges of aligning the instrument with jobsite control and obtaining prism lock. Now we have more good news: this intuitive solution makes the system set-up process quicker and easier. The Topcon LN-100 is a three-button, auto-leveling instrument. Just center the instrument over your control point and engage the three buttons for power, WiFi, and auto-level. Then join the “LN-100 WiFi” network from your iPad, and begin the step-by-step in-app set-up guide. This intuitive guide aligns the prism to the instrument based on standard “known-point” or “re-section” workflows. (NOTE: the iPad running BIM 360 Layout is attached to the prism rod)
Once through the set-up routine, you are off and running---navigating the jobsite point-by-point using the point list view or tapping into the model and locating a specific point using standard iOS gesture-based controls. We’ve designed the app based on input and job site testing with BIM 360 customers: DPR, Mortenson, and PCL Construction. Their input and direction played a critical role in developing the BIM 360 Layout app from a contractor/field engineer perspective.
