Topcon Positioning Group now has a new building information modeling unit—the LN-100—designed specifically for construction layout. Said to be the world’s first 3-D positioning system, the LN-100 allows for smooth integration and flow of project data from the design to construction stages. Company officials say the BIM unit provides straightforward operation and makes it easier for contractors to perform construction layout. An included wireless controller enables the BIM unit to function from anywhere on the project site, with an operating range that can cover a 200-meter diameter area. Once properly angled, the LN-100 laser can immediately locate the exact design point or line that needs to be staked out. The LN-100 can also lock onto a prism and guide an operator to the next design points, company officials say. Additional information on this product can be found on the company website.
