Since last year, traditional GIS positioning companies such as TopCon, are getting into the act of providing integration of Building Information Modeling workflows and field layout with their recent collaboration with Autodesk. This collaboration involves an Autodesk BIM 360 app for iPad to make it easier to locate BIM coordinates precisely on a construction site. Designed for general contractors and MEP professionals, the app controls a robotic total station and the LN-100 3D positioning system from Topcon. As-built data can be fed back into the design model via BIM 360 for quality assurance. Topcon was traditionally considered a geospatial company but they have extended their reach into many other industry segments now, including the area of BIM.
