HIGH DENSITY LASER SCANNING PROJECT
High Density laser scanning (LIDAR) is a state-of-the-art tool that can quickly collect extremely accurate and detailed information during a topographic survey. Our technicians analyze that data and create a 3D digital replica of the site, accurate down to 3-millimeters. This comprehensive model documents all existing conditions and eliminates the need for costly site visits because all the data is available to the owner and the design team in real time. In addition to being more accurate and comprehensive than traditional surveying, LIDAR is also much quicker and safer than traditional methods. LIDAR’s remote data acquisition requires fewer field staff on site, and allows them to accurately record information while out of harm’s way, such as in busy intersections or parking lots. This better, more comprehensive survey model will result in a more complete design solution, more concise and complete construction documents, and fewer change orders down the road. For example – knowing accurate adjacent grade heights can eliminate change orders for additional asphalt cut backs when field matching. It can also mitigate costly litigation later in the project by providing a well-documented picture of existing conditions at the beginning of the project. No arguments about if damage was there before construction started. Understand the whole picture before you start your project. And then share that picture with the entire team. Use LIDAR to quickly and safely create a more comprehensive 3D model for your design team to build upon.
LIDAR SCANNING DATA IS MULTI-DISCIPLINE FRIENDLY; THE POINT CLOUDS CAN BE IMPORTED INTO AUTOCAD AND REVIT MODELS, USEFUL FOR MECHANICAL, ELECTRICAL, AND PLUMBING DISCIPLINES, AS WELL AS ARCHITECTURAL AND CIVIL
Rocky Mountain College, Billings, Montana; Using LIDAR, Sanderson Stewart’s surveyors were able to provide the College with an extraordinarily accurate view of their campus facilities, right down to the brick detail of the buildings. This allowed the college to map the entire campus at a fraction of the cost of conventional survey methods.
