Most people think BIM ends in Revit, but in reality, this is where it actually begins.
Everything is placed exactly where it belongs.
No guesswork. No interpretation.
It is a laser-based layout system directly connected to BIM models (Revit / Navisworks).
The site team can see digital coordinates physically projected on the site.
Direct BIM Integration
BIM models (from Revit, IFC, etc.) are uploaded directly into the Topcon laser layout system, eliminating the need for manual drawing interpretation.
High Accuracy Layout
Topcon laser machines provide millimeter-level accuracy, ensuring walls, columns, MEP points, and openings are marked exactly as per the BIM model.
Faster Site Layout
Compared to traditional tape and chalk methods, BIM to laser layout reduces layout time drastically and speeds up construction progress.

4. How the Machine Works on Site
5. Where Topcon Laser Layout Is Commonly Used
Uses Mixed Reality (MR) technology to place 3D building models directly on the real construction site
Works with smart glasses or tablets
Shows walls, columns, MEP services, and structures at full scale
Improves visual understanding compared to 2D drawings
Helps in early clash detection before construction starts
Reduces errors, rework, and material wastage
Allows quick design review and faster decision-making on site
Improves coordination between clients, designers, and contractors

Robotic Total Station Technology
Machines like LN-100 / LN-150 work as robotic total stations, automatically positioning themselves and projecting layout points without constant manual adjustment.
Faster Site Layout
Compared to traditional tape and chalk methods, BIM to laser layout reduces layout time drastically and speeds up construction progress.
Reduced Human Errors
Since layout data comes directly from the BIM model, chances of measurement mistakes and rework are very low.
Single-Person Operation
One technician can operate the Topcon laser machine using a tablet, reducing manpower requirements on site.
Easy On-Site Updates
If the BIM model is revised, updated layout points can be quickly reloaded and marked on site without redoing the entire process.
Clear Point Marking
The laser clearly marks points for walls, sleeves, anchor bolts, electrical boxes, plumbing lines, and structural elements.
Better Coordination Between Teams
Architects, engineers, and contractors work from the same BIM data, improving coordination and avoiding clashes.
Works Well for MEP & Structural Layout
Especially useful for complex MEP layouts, slab penetrations, and accurate structural positioning.
Cost Saving in Long Run
Although the machine is an investment, it saves money by reducing rework, delays, and material wastage.
Ideal for Modern Construction Projects
Perfect for residential, commercial, and large-scale projects where precision and speed matter.
The Topcon Laser Layout Machine is a modern robotic layout system designed to bring BIM models directly onto the construction site with extreme accuracy. It works as a robotic total station, specially developed for BIM-to-Site layout, making it one of the most trusted tools in today’s digital construction workflow.
The BIM model is prepared and layout points are finalized
Data is transferred to the Topcon controller
The machine is placed on a stable tripod and leveled
Reference or control points are set
The operator selects layout points on the tablet
The laser projects exact locations on site
Physical marking is done using chalk, marker, or spray
Wall and partition layout
Column and grid line marking
MEP sleeves and penetrations
Electrical box and plumbing point layout
Anchor bolts and inserts
Façade and interior fit-out works
