Dunbar.jpgDunbar Mechanical Utilizes Trimble® RTS Series Robotic Total Stations
for Predictable Excellence

The professionals at Dunbar Mechanical provide project management services that go beyond drawings and flow charts to incorporate all of the real world conditions which are part of your project. To that end, we utilize the Trimble® RTS Series Robotic Total Station system to take information from the plans, check this against actual site elements and ensure accuracy in all details. This extensive coordination between manufacturing fabrication and site installation has many benefits for our clients.








Dunbar’s trained professionals can accurately and individually lay out hundreds of points in a single day, even when the design is complex, with the help of Trimble® equipment and technology. Shown here on the site of a recent Dunbar project, the system incorporates data from the project plans/CAD layouts and enables laser accuracy in the field. The curved walls of the facility provided no fixed corner points for layout reference on this project. The Trimble® system is set up on site and programmed with control points for the exact location of each bathroom plumbing assembly. The fabricated underground piping assemblies (completed in Dunbar’s Production Manufacturing Fabrication Facility) are positioned in place and the ground marked for excavation. When the correct depth is reached each unit is aligned through the center of the casings to the exact points indicated on the drawings. The units are then secured in place and progress continues on the site.
