Gathering highly accurate, detailed survey data for improvements to existing roadways and runways can be dangerous and expensive. Traditional surveying does not always provide the detail needed for roadway improvement projects and can be dangerous in areas with heavy traffic. Keeping field personnel safe while collecting accurate as-built data using traditional surveying methods often requires closures that impede daily operations and costs the public time and money. Terrestrial and Mobile laser scanning are an accurate, safe, and cost-effective alternative.
The development of laser measurement technology has improved the workflow and efficiency of surveying methods used for decades by enabling the capture of data at the speed of light. Using remote data collection technologies in conjunction with proven workflow and procedures, CoignAMT offers detailed, cost-effective topographic surveys of highways, tollways, urban arterial roadways, runways, bridges, and elevated structures. Given the added value of acquiring significantly more detailed data in less time without impacting traffic flow or interfering with daily operations proves to be a valuable solution for today’s designer.
On a typical project, detailed three-dimensional (3D) data is remotely captured with an average of 3-inch spacing or better throughout the entire project. Each data point has a 3D coordinate value relative to the desired coordinate system when supplemented with control monuments tied using traditional surveying methods. This dense “point cloud” data is then referenced into AutoCAD or Microstation allowing for technicians to easily extract the necessary vector information. The raw data is also decimated and used to create detailed digital terrain models (DTM) representing a very accurate depiction of the actual roadway. Beyond typical topographic data, information such as the location of pavement failures, cracks, areas of stress and possible ponding, and aerial utilities within and beyond the project limits are easily identified. CoignAMT also uses this cutting-edge technology to collect very precise deformation measurements for monitoring surface deviations.
CoignAMT’s extensive facility and asset management experience allows us to look beyond the current objectives and utilize HDLS data to help our clients become stronger by aligning their assets and operational practices with their strategic initiatives. In the past, it was not economically possible to capture this level of detail, but CoignAMT has repeatedly proven the benefits of this service to the transportation and aviation industries.
Ground-based terrestrial laser scanning is a safe, accurate, and inexpensive technology that can be used to supplement light detection and ranging (LiDAR), low-altitude mapping photography (LAMP), or traditional surveying data.
When your project demands superior accuracy, CoignAMT’s ground-based terrestrial laser-scanning services can save time, money, and lives.
